You need to consider one main thing... Space is a 4 Dimensional object. Matter is 3D. The reason this whole concept messes with our head is because it's hard for us to actually visualize a higher dimension. Think of a square made of 4 (1D) lines - easy. A cube made of 6 (2D) Squares and now - quite simple duh.... ..... a hypercube or tesseract (4D) made of 8 (3D) Cubes.... turns your brain inside out hoping someone just hit you on the head real hard as that would be an easier way to explain..... Also consider this.... If you lived in a 2D world (assuming you were a square) would see everything else as 1D lines. and the fact that you see in 3D only means that you live in a 4D space.

Can anyone explain how this works with different frames? Like for example watching from a particular frame the earth rotates in a horizontal circular direction But if the same person rotates (let's say 90°to the left) then the earth should start rotating at vertical circle. But that does not happens Then it should means that curvature of space-time is in a particular direction. So why does this curvature happens in a particular direction?

So, these idiots are basically saying that gravity has a "speed", meaning the attraction between two masses has to bend the fabric of space to reach the other object... Wow !!! I knew this is a complete nonsense when they say the "gravitational waves" detected by LIGO came to earth after 1.3 billion years or so... A device that detects variations of length equal to 1/10,000 the width of a proton over 4,000 metres, such a croc of s**t !!! ... and how do they know these variations of length detected by LIGO come from gravitational waves and not, say, micro earthquakes, temperature variation of the arms, some atoms of the mirror surface that evaporated due to heat, interference from gamma rays, small variations of the earth's gravity (probably caused by magma movements or so), variations of the wavelength of the laser caused by fluctuations in the power grid, your pick...

At the end there, wouldn't you need to translate into 4D spacetime instead of just 3D space to get the complete picture? There's no good way to visualize or display 4D structures, I know, but shouldn't it have been mentioned?

2 physicists walk us through THEORETICAL BLAH BLAH BLAH in 2 minutes ... and what are we left with when these two PhDUHs who are ignorant of facts that Einstein was also ignorant of ... ? ANSWER one question ... *did Einstein suspect that GRAVITY was CHIRAL?* Now why did Einstein's [died in 1955] woo woo science which was ignorant of the Wu experiment in 1956 continue to live on? geesh and DUH folks the Einstein god was ignorant of a fact, that everybody knows today ... the 4 forces of physics are asymmetrical NOT symmetrical as his generation believed ... standard model of physics was turned upside down in 1956 ... when Einstein was 6 feet under ... ... so after about 100 years you are left with just more THEORETICAL bullshit waiting so desperately for another brain fART to take physics to the next level of AHA FAIL FAIL FAIL the paradox of the human intellect sharing a body with a dimwit lives on ...

To maintain a constant acceleration we need a energy supply. In other words if a constant force is applied to a body, for this we need a constant energy supply also. Now if we take earth and moon, earth is applying its gravitational force on moon on a constant basis, now from where earth is getting this energy from ? Certainly every body with a mass exert a gravitational force, but to do this where does a mass gets energy from ? If we consider above logic and if there is a energy source, will it decay like all others, doe that mean amount of gravitational force earth exerting now will be less and less with the time.

No shit 3d messes einsteins concept completely. Let me set you straight. The light beam approaching a star does not get pushed out by curved space caused by the star. The foreign light beam gets bumped around our sun because our sun is pushing out light particle force. The original light beam from a distant star resumes its spooky connection from a distance as it travels around our sun. All you jave to do is git me and you'll eat your pudding.

The rubber sheet analogy is okay up to a point, it gives the general idea, BUT rarely reminds people that there should a kind of infinite number of 'rubber sheets' surrounding any mass. Think in 3 dimensions; and then imagine that the space also has a time element too. :0)

Einstein's Theory of General Reactivity with the idea of ​​the space-time fabric is simply absurd, and goes totally against the physical-observational reality. In the event that it were real and existed, that tissue should totally block or block the light that would emanate from the stars, why space surrounds and is in all the neighborhoods or on the sides and above the stars and is not only below them as a floor or as I see in the drawings and graphs of modern cosmology on relativistic space-time fabric. Then, that ethereal fabric of space-time should be filling the entire environment of the stars and as it is present for all directions in the environment of the stars, the lights that the stars emit would never escape and be emitted by space, that the particles or continuous elements constituting the fabric were going to sweep the light until it absorbed it totally, as a material obstacle! Even if the fabric of the space-time of Einstein's relativity was a kind of ground for the stars and was just below them, as shown in the drawings and graphs of modern cosmology, the curvature that the stars made in that one tissue would form a slope, and the planets would all go down that ramp to the surface of the sun, fall on the Sun and they would all be destroyed. This questioning of general relativity can be done experimentally with a simple simulation, it is just taking a trampoline and placing in its center a heavy bowling ball that would correspond to the Sun, and on the peripheries of the bed put gude balls, tennis and several sizes smaller. It will be verified experimentally that the heavy bowling ball will make a slope in the trampoline and the smaller and lighter ones will all roll in that decline falling on the big and heavy central ball! The following video shows an example of scientific refutation in physical - experimental simulation of the general relativity of Einstein, in the video shown below by the physics teacher himself! https://www.youtube.com/watch?v=l-BVkHRLPfo The video above is in accordance with my experimental physical refutations of relativity, if there were curvature of space, the planets go down the slope in the fabric of Einsteinian space - time and roll down that ramp falling on the Sun and being all completely destroyed! Then, existence as we know and observe would be impossible. Not to mention that the teacher in the video, throw the balls to the side of the slope and turning them to obey a translative orbit and try to make it seem proven that with that Einstein's general relativity is scientifically proven. The demonstration that he wanted to give of relativity had the opposite effect of what he tried to pass, served to refute experimentally what he accepts as well as an absurd belief about curvature of space, without empirical and consequently scientific foundation! Then, in various ways, with solid logical, philosophical, empirical reasoning and physical - experimental simulations, the theory of general relativity suffers from immense physical difficulties and impossibilities is rigorously refuted.

PelycheeaceRA did not read all his comments, but 1) general relativity does not even postulate the existence of a "fabric" of space-time. the whole fabric thing was only created to give lay people an understanding of the concept. Answer 1: False Einstein in a 1920 letter to Leipz University in response to his Belgian physicist friend Paul Eiwseinherofest said clearly that the idea of ​​time space curvature would imply a new type of ether introduced into the theory of relativity, that space without ether was unthinkable, that purely mathematical space exists only on paper 2) The reason why marbles spiral toward the central mass in your video is because they lose momentum due to friction. there is virtually no friction in space, so the planets continue to orbit (conservation of angular momentum) Answer 2 : False again, because once the curvature of the ether time space is affirmed by the contact of the masses of the stars and stars on this material structure pressing to the sides for it to bend and through its deformation attract the astronomical bodies, these planets are in contact with the physical structure - time space or time space, all the friction observed in the example of the burquinhas falling in the center of the elastic bed should also be observed necessarily with the flexible physical structure time space denominated by the Einsteinians of time space fabric.

Space does not suffer from curvature of anything and does not interact with anything. For matter and bodies move, space most probably must be empty and immaterial, if not the movement of things, bodies and phenomena or it would be difficult or impossible! They are the things that move in space, but space itself is not moved by anything, is not distorted or curved by bodies or stars and remains always in its usual place. As César Lattes said, Einstein was foolish. Einstein's theory of relativity is a pseudo-scientific theory, in the very terms of relativity it is spoken in pseudo-Euclidean metric, pseudo-Riemannian variety and etc ... (In English) "Space-time intervals, conceived in a variety (mathematical term), define a pseudo-Euclidean metric called a Lorentz Metric.This metric is similar to that of distances in Euclidean space, but it is observed that while distances always are positive, space-time intervals can be positive, null or negative Events with a space-time interval of zero are only separated by the propagation of a cones of light light Events with a positive space-time interval, in the sense that the observer was traveling between them Spacetime, seen in light of this pseudo-Euclidean metric, constitutes a pseudo-Riemannian variety. One of the simplest and most interesting examples of spacetime is R4 with the space-time interval already defined behind. This, is known as Minkowski space, being the usual model of the Theory of Relativity restricted. In contrast, General Relativity proposes that the underlying variety should not be flat in the presence of gravity, so space-time rather than Minkowski's space is preferred. Source: http://es.wikipedia.org/wiki/Espa%C3%A7-tempo Below are some of my reasonings and philosophical, logical and empirical demonstrations that space is empty and immaterial: Space is immutable and indestructible because it is empty and immaterial, it is the things and bodies that move in space and move only because space is empty, immaterial and immutable. When we move our arms, what is moving is only our arm over space, but space by vacuum and immaterial manages to cross our material and corporeal arms and maintain itself in its immutability and indestructibility. When we destroy and demolish houses and walls, what is destroyed are only the material buildings, but the space where this building was standing, remained unchanged and indestructible in its same place as always. We never manage to move the space of the place, because it is empty and immaterial, being consequently immobile, indestructible and not reactive with anything, with any material body.

Space-time is a concept not a physical entity....The moronic idea of time being the fourth dimension can be traced back to d'Alembert from 18th century. Einstein space-time has no physical reality and is there to replace the Aether...Time  is just a Relative Measure between two movements ....there is no metaphysical Time being part of a fourth dimension .....the whole thing is a  FRAUD. The bending of light is caused by refraction of light thru plasma matter (plasma that form  the corolla of the sun), nothing to do with space-time curvature.

JohnnyD63007 (3 месяца назад)
Still there is no prediction made by General Relativity...The result from the eclipse in 1919 are not meaningful since they took result from north Africa and discarded the one from Sobral,  Brazil .They had 1.5 '' instead of 0.90 ''(which had an error more than 50%) ....the whole thing is just a scam . It's ridiculous to think that a concept like time ( derived from measurement between two relative  movement) can become somehow a secret dimension in union with the already existing 3 dimension of space....Maybe it's good for science fiction books and Hollywood movies .It gives you the impression that time is an entity by itself that can be change (time dilatation)....The only thing that dilates I thing is  Einstein's head....

sure. theyre mathematical tools we can use to describe reality and make predictions. thats the whole point.

Time as a 4 th dimension is useful to track a movement just like when you plot speed as y variable against  time for x variable to track acceleration using derivative or force as a y variable against time for x variable to calculate the total impulsion using  integral. Those are MATHEMATICAL TOOLS not REALITY. Time as a 4 dimension attached to space dimension is a FANTASY inspired by French Scientist Jean Le Rond D'Alembert who came up  first with that concept in 18th century .Einstein then paid a visit to an other famous mathematician ,David Hilbert, to put that fancy metric (space-time) in mathematical equation (and by the way , big bang theory and black holes are direct chimeras offspring from that theory)....Einstein is a plagiarist... he took e=mc2 from mathematician Henri Poincare who came up with that conclusion 1 year before him (in 1904). The previous formula calculated by others before Poincare  was e= 4/3 mc2 but Poincare subtracted  to it 1/3 mc2 to take in account the energy needed  to stabilize the electron (and prevented it to become a 'crepe') because of that theoretical space compression along  the x axis. Also his theory of special relativity is inspired from Poincare relativity and Lorentz transformation .When he talks about relative simultaneity is talking about relative perception not reality ...just an other twist from Einstein so called thought experiment...The photoelectric effect is just an application of Max Planck quantic formula for energy (E=hv) applied to the electron. Einstein didn't invent the H bomb , Oppenheimer did...Einstein is just an opportunist and a plagiarist who happen to be at the right place at the right time  and with the help of  Zionist controlled media , has been elevated to a world genius hero stature .

Nearly 1400 yrs before its in Quran.... --Chapter 36, verse 38-40. “It is not for the Sun to overtake the Moon nor for the night to outstrip the day; each one is swimming in a sphere.” --Chapter 50, verse 6.
"Do they(Man) not look at the sky above them, how We have built it and adorned it, and there are no rifts in it." --Chapter 31, verse 10:
"(God) created the sky without any pillars that you can see..." --Chapter 51 , verse 47: And the sky, We(God) built it with craftsmanship and We are still expanding it. --Chapter 81, verse 15-18 So verily, I swear by the stars that are veiled(Have blackness/hidden for our eyes). And by the (sweeping) stars that move swiftly and hide themselves. And by the night as it departs; And by the dawn as it brightens. The holy Quran mentions the black holes by its very specific characteristics, these are : 1 - They are running stars. 2 - They are veiled or receded. 3 - They are sweeping stars. --Chapter 56, verse 75-77 Then I(God) swear by the places where stars fall/drop. And indeed, this is a great evidence/oath if you could know. That this Quran is a very noble book(Sayings of God, signs for those who read & Research).

2:37 isn't that grid bent in the wrong direction? as far as i get it, the space is suppressed by a heavy mass object, the light goes around it. Imagine a 3D grid, now press a ball in it, the lines would bent convex around it and not towards it.

K. Chris Caldwell (5 месяцев назад)
There are only two entities in the universe: Energy, in all of its forms, and space. Period. Time is only apparent from the interaction of energy with space. Some energy here, a change in energy here, let us call that one second. Or, some energy here, over there, back here, let that be called one second. Time then is not a real entity, the passing of time is, but time itself is a change of energy in relation to space. It follows then that _space-time_ is nonsense. To say _space-time_ is to say _space-and change of all the energy of the universe in relation to all the universe's space._ Or to use space as a coordinate is to say, 3 from that, 4 from that, 6 from this, and all the energy in the universe as related to all the space in the universe. Yes, _Relativity_ is real, but the interpretation is wrong. Until mankind defines time properly, physics and the understanding of the universe will remain stymied.

A giant stone inside a water bents or displaces water. But only the water exerts the pressure of its displacement back on the giant stone. How can some other object, maybe a small nail get attracted and stick on to this giant stone. Isnt that the gravitational pull explained here in a manner. But I feel this is impossible. because only space is supposed to be bent. And empty space is empty and how can emptiness exert pressure or force on other objects.

+PelycheeaceRA Atleast, if u know it better way, please give guidelines to understand the curvature of space time. I am hardly able to fit this concept in to understanding the real world. For me it looks like that is a much more complex determination and leading me to flat earth concept because of curved space time.
KV Jithin (3 месяца назад)
+PelycheeaceRA Buddy. When physics can't explain certain things, don't leave it to philosophy or religion. As I know, "why" is always better explained by physics (Except this subject as I know). No philosophy, no religion does ever explained "why" or "how" as better as science does.
PelycheeaceRA (3 месяца назад)
well no it doesnt explain "why" things follow geodesics. just like quantum physics doesnt explain "why" opposite charges attract each other, or "why" two identical fermions cant occupy the same quantum state. but its a representation of reality that fits our observations better than the 3d method. and thats the whole point of physics. "why" is a question for philosophy or religion, not for physics.
KV Jithin (3 месяца назад)
+PelycheeaceRA You explained well from a 4 dimensional perspective. But the problem here needs more details to prove. First of all there is no such thing as 3 dimensions or 4 dimensions in the real world. Its just a globally accepted term created by human mind to analyse real world materials fundamentally. In 3 dimensional system, we measure only length in horizontal (x), vertical (y), and field depth(z). It doesnt mean that the world is 3 dimensional, but we humans use this method to analyze any particular object in size using 3 dimensional method. Now if u want to reason out why do objects fall, using 3 dimensional system, u will get a straight down, because the basic of 3 dimension system is implemented with the factors of horizontal, vertical etc Its basic itself is formed from us standing on earth. Now if u implement a four dimensional system where the 4th axis is time, it simply just went to a complex method of analysis of real world material. Only the analysis method is changing and u r getting a different shape result of graph representation. Such as u said above, using that complex 4 dimensional analysis, if u will reason out, why do objects fall, the 4 dimensional analysis (space time) was made to be curved and objects fall can be graphically represented as a straight line. Graphically, but the real world is still real world, and its not just these 4 dimensions that exist simultaneously. My point is simply easy to understand if u can relate this example. Consider water freezing at 0 degree celcius. Well its again another human made analysis to relatively understand temperature of any material. If u use this system of measurement, the water always freezes at 0 degree celcius, but if u use another system of temp measurement such as kelvin, u get the same water freezing at 273 k. This explains that if u use two methods of analysis, u get two entirely different results. But it doesnt explain why water freezes. Now bring up the real question, as why do objects fall. (1) If u use the 3 dimensional analysis, u are pointing a negative value in the y axis or a straight vertical downward graph representation. (2) if u use 4 dimensional method of analysis, u get a straight graphical representation, since the spacetime method is explained to be curved around. But it doesnt explain why do objects fall, that only gives a different graph representation or value. It is different simply because the method of analysis is different. The difference doesn't prove nor explain the fact as to why do objects fall.

spaceTIME is bent. things move in straight lines unless a force acts on them. but a line that looks straight in 3 dimensions doesnt have to be straight in 4 dimensions. imagine a curved stick. if you hold it so that the direction of its curvature aligns with your line of sight, you dont see the curvature. thats why the "time" in spacetime is important. when an object is attracted by gravity, it still follows a straight line in 4 dimensional spacetime (called geodesic). theres no force needed. its just that spacetime is curved in a way so the objects FUTURE doesnt coincide with a line thats straight in 3 dimensions.

The Physical characteristics of TIME in relation to Time Travel The presence of matter gives birth to Time being the ideal means by which man can ascertain the perfection of the movement through which God created the universe. As there can be no Light without the sun, so there cannot be TIME without matter. TIME is a tool for man like the stethoscope that reads the beats of the heart but without ever being able to intervene or influence the way the heart works or functions! https://plus.google.com/+jameswiliams How God created Time http://curezone.com/ig/i.asp?i=44451 God bless

These all are theories with no credible evidence. Infact Gravity itself a theory to define how objects fall down straight and how things work. But there is no physical evidence of such force.

things fall. we call that phenomenon "gravity". you can argue about what causes it, but you cant deny that it exists. or are you denying that things do in fact fall?

say if there was a 3d trampoline with sun at the centre then not all planets would have almost the same plan of orbit. some would be rotating on a plain that passes through sun's north and south pole and others on plain through sun's equator and yet others on even different plains. but even more likely, they would not orbit. they would just smash into sun and merge. afterall, in any kind of trampoline , whether 2d or 3d, it's all downhill once you are inside the depression.
PelycheeaceRA (3 месяца назад)
the planets orbit in one plane because they also attract each other. they dont crash into the sun because while they keep falling towards it, they keep missing the sun because of the tangential component of their orbital velocity. and they dont loose that velocity because theres no friction in space.

Why does space bend due to gravity
AL Can (7 месяцев назад)
Planets don’t sit on space, space contours, or squeezes, around objects equally on all sides. This is what causes planets “gravity”. The object in space has a magnetic field that causes a sort of “top and bottom”. The stretched out middle of the object, due to the magnetic field and the squeezing of space, is where planets gets “caught” and end up circling around said object, gravity.

If the fabric of space warps massive objects shouldn’t space itself have a boundary? This boundary should deflect the fabric of space in all directions in the universe. What if space was program at a scale that it knows what size it needs to be to contain all the matter and dark matter from the expansion it’s self and keep everything within the time to expand out into the multiverse?

Einstein's Theory of General Reactivity with the idea of ​​the space-time fabric is simply absurd, and goes totally against the physical-observational reality. In the event that it were real and existed, that tissue should totally block or block the light that would emanate from the stars, why space surrounds and is in all the neighborhoods or on the sides and above the stars and is not only below them as a floor or as I see in the drawings and graphs of modern cosmology on relativistic space-time fabric. Then, that ethereal fabric of space-time should be filling the entire environment of the stars and as it is present for all directions in the environment of the stars, the lights that the stars emit would never escape and be emitted by space, that the particles or continuous elements constituting the fabric were going to sweep the light until it absorbed it totally, as a material obstacle! Even if the fabric of the space-time of Einstein's relativity was a kind of ground for the stars and was just below them, as shown in the drawings and graphs of modern cosmology, the curvature that the stars made in that one tissue would form a slope, and the planets would all go down that ramp to the surface of the sun, fall on the Sun and they would all be destroyed. This questioning of general relativity can be done experimentally with a simple simulation, it is just taking a trampoline and placing in its center a heavy bowling ball that would correspond to the Sun, and on the peripheries of the bed put gude balls, tennis and several sizes smaller. It will be verified experimentally that the heavy bowling ball will make a slope in the trampoline and the smaller and lighter ones will all roll in that decline falling on the big and heavy central ball! The following video shows an example of scientific refutation in physical - experimental simulation of the general relativity of Einstein, in the video shown below by the physics teacher himself! https://www.youtube.com/watch?v=l-BVkHRLPfo The video above is in accordance with my experimental physical refutations of relativity, if there were curvature of space, the planets go down the slope in the fabric of Einsteinian space - time and roll down that ramp falling on the Sun and being all completely destroyed! Then, existence as we know and observe would be impossible. Not to mention that the teacher in the video, throw the balls to the side of the slope and turning them to obey a translative orbit and try to make it seem proven that with that Einstein's general relativity is scientifically proven. The demonstration that he wanted to give of relativity had the opposite effect of what he tried to pass, served to refute experimentally what he accepts as well as an absurd belief about curvature of space, without empirical and consequently scientific foundation! Then, in various ways, with solid logical, philosophical, empirical reasoning and physical - experimental simulations, the theory of general relativity suffers from immense physical difficulties and impossibilities is rigorously refuted.

How can a massive body be placed on the (space-time) trampoline to make it bend... I mean that how can time be treated as a space related phenomenon and bend... Please someone help me...!!
Wes Baumguardner (7 месяцев назад)
Einstein was a lunatic, not a scientist. The model does not work for 3D space, which is quite obvious. Neither space nor time have properties of physical geometry and cannot be bent or warped. Only energy has physical properties, which is why all observations are made of and with energy. Space is not energy and is both inside and outside of all energy so when energy moves, space is completely unaffected, however other energy is affected. Only energy can effect energy. To claim space effects energy is equivalent to saying leprechans effect energy.

Space does not suffer from curvature of anything and does not interact with anything. For matter and bodies move, space most probably must be empty and immaterial, if not the movement of things, bodies and phenomena or it would be difficult or impossible! They are the things that move in space, but space itself is not moved by anything, is not distorted or curved by bodies or stars and remains always in its usual place. As César Lattes said, Einstein was foolish. Einstein's theory of relativity is a pseudo-scientific theory, in the very terms of relativity it is spoken in pseudo-Euclidean metric, pseudo-Riemannian variety and etc ... (In English) "Space-time intervals, conceived in a variety (mathematical term), define a pseudo-Euclidean metric called a Lorentz Metric.This metric is similar to that of distances in Euclidean space, but it is observed that while distances always are positive, space-time intervals can be positive, null or negative Events with a space-time interval of zero are only separated by the propagation of a cones of light light Events with a positive space-time interval, in the sense that the observer was traveling between them Spacetime, seen in light of this pseudo-Euclidean metric, constitutes a pseudo-Riemannian variety. One of the simplest and most interesting examples of spacetime is R4 with the space-time interval already defined behind. This, is known as Minkowski space, being the usual model of the Theory of Relativity restricted. In contrast, General Relativity proposes that the underlying variety should not be flat in the presence of gravity, so space-time rather than Minkowski's space is preferred. Source: http://es.wikipedia.org/wiki/Espa%C3%A7-tempo Below are some of my reasonings and philosophical, logical and empirical demonstrations that space is empty and immaterial: Space is immutable and indestructible because it is empty and immaterial, it is the things and bodies that move in space and move only because space is empty, immaterial and immutable. When we move our arms, what is moving is only our arm over space, but space by vacuum and immaterial manages to cross our material and corporeal arms and maintain itself in its immutability and indestructibility. When we destroy and demolish houses and walls, what is destroyed are only the material buildings, but the space where this building was standing, remained unchanged and indestructible in its same place as always. We never manage to move the space of the place, because it is empty and immaterial, being consequently immobile, indestructible and not reactive with anything, with any material body.

Here's some advice for the uploader: The trampoline analogy is entirely unhelpful, and the reason people say "oh, I get it now" is that they assume that you don't know what you're talking about or that you're a terrible teacher and they don't want to embarrass you. Listening to you any further would probably be a complete waste of their time and if they say "oh, I get it now" perhaps you'll shut up and leave. It's a very misleading analogy. Explain it in 3 dimensions. It's not that hard. Your 3D diagram isn't even consistent with the trampoline, because the trampoline is wrong.

Well the 3D version would be like water and has a velocity where Mass can fload. Can also see iT as different layers like oil on water, would also explain the “waves” Funny would be when at the start all matter was at he same level, but “time” and “space density” Lets matter sink and drift. Together with the “waves” “current” makes ‘m spin while the object with the most Mass Lets em form a galaxy. And are the waves the golden ratio? That would explain why we see iT everywhere.

The Einsteinian concept of warped "spacetime" is total nonsense folks. Space is nothingness and nothingness can not be bent, flexed, stretched, twisted, warped, weighed, or painted green! One does not need to warp space in order to explain how the straight line path of a photon gets deflected as it passes near a massive body in space. All one needs to do is say that the photon has some gravitational mass and it is being attracted to the body's gravity field.
StillCloser (22 дня назад)
Except that according to physicists photons do not have mass, so why on earth can light bent by a gravitational field? Bonus question: It's been said that photons do not have mass but have momentum... Since Momentum equals Mass times Velocity, seems pretty fair to conclude that whatever the speed is, photons shall never have momentum...

facepalm (7 месяцев назад)
It shouldn't, because they both lack the dimension of time. The way it is explained here and in virtually all popular science material available, is that light just follows the curvature of space. And the analogy with marbles on a sheet with dimple is actually using your intuitive understanding of gravity, to explain gravity! If you hold an apple in your hand and release it, then why does it start to move towards the Earth? It's not because it follows the curved space, because it's not moving to begin with. It's because it also follows the curved time! That is a very important detail. You can not explain gravity without taking time into account.

Don't listen to this bullshit. Space does not Warp. You can see the star behind the Sun during eclipse not because space is being warped. It's the magnetism of the Sun that is repelling the light. Exactly like you would expect from magnets. Einstein's theory is meant to confuse people. They will do everything but say what gravity is magnetism. Which is the only Force.

Well, I explained to my son several times that when an apple drops from a tree it's not the apple falling down, but it's the ground accelerating up till it hits the apple. Thats hilarious to my son because the entire earth would be expanding continously. But thats just because he does not take curved space time into account. There is no difference between the force when accelerating an object or force as a result of gravity. It's just the same thing.
