FICTION (25 days ago)
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.

To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view. Tesla
K. Chris Caldwell (1 month ago)
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.

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.

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.

Why does space bend due to gravity
AL Can (2 months ago)
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?

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 (2 months ago)
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.

Clock In The Centrifuge Is Just An Einstein Way Of Measuring Gravity. Gravity Is A Bend In Space. When You Are On An Amusement Park Ride & Are Pushed Outward, That Is Gravity. A "Bend In Space You Went Through" Without Even Knowing It. It's Not Theory It's Just A Measured Effect.

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.

u right I'll trust the random guy on the internet over 100 years of rigorously tested physics.
Ken Behrendt (2 months ago)
The vast majority of university's and institutions can still teach nonsense and make a nice profit doing so. In the second century a guy named Ptolemy came up with a model for the heavens that could predict, with some accuracy, the movements of the planets through the night sky. This model was taught to the children of the rich for over a millennium until a Polish astronomer named Copernicus came along and realized that i twas total nonsense and that the planets were not giant lights attached to concentric spherical crystal shells, all mounted together on giant iron axles, at the North and South Poles that rotated around a flat Earth at different speeds. To keep from being burned at the stake for daring to challenge the established paradigm, he waited until he was on his death bed to publish it. I do agree that space contains tenuous amounts of various gases such as helium and hydrogen, but Einstein's general theory of relativity claims that if one removed all those gases so he had a perfect vacuum, the proximity of a nearby large mass, such as that of a planet or star, would cause the surrounding vacuum to experience a warping of its "4 dimensional space-time" shape. This alleged warping is then used to explain how the light from a distant star gets deflected as it passes close to the body. No one's observed this happening with planets, but only with our Sun during a total eclipse. Well, it turns out that the effect can also be explained by the distant star light being refracted as it passes through the gases being ejected from the surface of the Sun. One does not need general relativity for the explanation. Of course, if one wants to believe that nothingness can be bent, stretched, twisted, or warped, then he has a constitutional right to do so. He is also free to believe in the Sandman, the Tooth Fairy, the Easter Bunny, and Santa Clause as well!
THINKOFTHE CHILDREN (2 months ago)
How the fuck could you honestly say the theory is total nonsense? Why would the vast majority of universities and institutions (if not all, but I could be wrong) continue to teach this concept if it was total nonsense? Space is not nothingness, you're completely wrong. Hydrogen, Helium, Oxygen, Carbon, etc. all comprise the matter of space just like the pale blue dot we live on.

facepalm (3 months ago)
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.

This Matches Exactlt what GOD stated in the holly Quran about how planets and other objects in space are behave in space 1400 years ago.... The Verse which states this is as follow: Curved Spacetime: Surah Al-Anbya [21:33] "And it is He (Allah) who created the night and the day and the sun and the moon; all heavenly bodies in an orbit are swimming." Big bang theory + water creation of life: Surah Al-Anbya [21:30] “Have those who disbelieved not considered that the heavens and the earth were a joined entity, then We separated them, and made from water every living thing? Then will they not believe?” Expanding Universe: Surah Adh-Dhariyat [51:47] “And the heaven We created with might, and indeed We are expanding it” (Quran 51:47)

The rubber sheet actually uses gravity (because gravity will pull down the heavy ball in the 1st place) to explain gravity. This is not how explanations work. You need to use something that is not a direct consequence of gravity - in order to explain it, and so far this is not what the rubber sheet actually does. But on the other hand, it might not explain gravity (obviously it's much more difficult) but it gives people a better intuition of the weirdness of our reality. If you really want to understand gravity, you need to let go of EVERYTHING and I mean *EVERYTHING* your senses tell you. I'll just say this to show you how much you need to let go... If you let an apple fall (in a vacuum inside a gravitational field) the apple doesn't fall. Its the floor that rushes up and meets the apple! The reason why the apple seem to fall (even though it doesn't) is for the same reason why the Sun seems to move in the sky (although it doesn't). Its US that move not the Sun or the falling object. Its us that move both in space and time, and suddenly release an apple - the apple has no longer any force acting on it (so it stays stationary) and our perception that creates the illusion of the falling apple when in reality the apple doesn't move. And it goes even weirder after this... So... yeah, better stick to the rubber sheet explanation!

If space-time bending is the reason for gravity Can u explain why we feel gravity at the top ,bottom ,and center of Earth Suppose the reason for gravity in earth is the massive earth bend space and time and that cause the gravity in earth Then we experience gravity only at the bottom of earth { south pole only} if the earth is a sphere How it is possible I think if the earth is flat the only this theory wil works If the earth is a flat and a massive body then we feel gravity every where in the f flat object And I didn't believe in flat earth I need answers
THINKOFTHE CHILDREN (2 months ago)
I know this is late, but please please please do not believe in the flat earth "theory". It is not based on any kind of scientific evidence. In fact, it is the total opposite. We feel gravity everywhere on earth because the earth exerts this gravitational force. Imagine a weighted ball on top of a flat sheet with nothing underneath the sheet. The weighted ball will dip a little bit into the sheet. If you were to throw in another ball, it would eventually fall towards the weighted ball. This is essentially how gravity works on planets. Our Earth is the weighted ball and we are the extra balls that naturally fall towards the center of the weighted ball. Earth is so dense and massive that it exerts a relatively large gravitational force that pulls the moon, satellites, and any other nearby space objects toward it.

Mass on trampoline is pulled by earth's gravity to make the curvature. Then what pulls masses in space-time so that those masses make curvature. If nothing is pulling, then space time fabric around the mass in space should bulge out due to presence of mass. Just not able to figure out the logic (magic-science). Please answer me. The sheet of trampoline itself is 2d . It gets curved due to gravity. Then how come space-time get curved if there is nothing below planets to make a curve due to it gravity.

Albert Einstein really had no idea on the basic of astronomy.Einstein was interested to Riemann geometry, but he had not realized that Riemann geometry is useless in astronomy.

For understanding that hypothesis and the test are not valid, physics training is needed; but more importantly is celestial navigation training. Unfortunately, physicists and astrophysicists are not trained to become experts in the field of celestial navigation. The navigators around the world will be easily to know the fatal mistakes of these hypotheses and test. Actually, general relativity cannot be proven or tested by in any means. No doubt, the entire tests that says ‘general relativity is correct’ really are the case of ‘knowing the result they wanted to get’.

Almir Hamzic That video shows zero scientific evidence. Big Bang Theory evidence includes the so called CMB and redshift. Vague terms in old books don’t count for much I’m sorry. Redshift has not been proven to be correlated with distance. Halton Arp has taken images showing quasars partnered with galaxies that have very different redshift, so the notion of redshift being a sign of distance is highly unlikely. If redshift is distance then galaxies are moving away at over the speed of light. Not likely at all. The Cosmic Microwave Background was supposedly measured by the cobe firas but it didn’t have a shield to protect it from earths radiation. And all the subsequent data was manipulated and improperly presented. This isn’t an opinion, it is fact and was presented for all to see. Their claims are accepted by those who simply haven’t looked or understood what’s involved. That’s about it as far as I know. BB has no solid evidence and if you go into it on just a basic level it’s obviously nonsense. Big Bang Theory includes silly assertions like no mass and infinite temperature.

I love the way physicists forget physics when it comes to Einstein's relativity . Like the assumption that light only travels in straight lines. If you've seen a mirage on the highway you are seeing light not travel in a straight line, and all it took was a little hot air.

Don Jobin Mirage happens because of the refraction of light, which happens because of the different “speeds” of light in different mediums. Light moves slower in denser mediums, and this causes it to change angles, but it still moves in straight lines. You’re probably thinking isn’t light speed supposed to be constant? The reason behind refraction doesn’t have a straight forward answer. I suggest you watch this: https://m.youtube.com/watch?v=CiHN0ZWE5bk

Trying to explain us spacetime but get the scientist with the worst accent. Well done!

Ne, bu cümleyi mi çevireceğim? Hiç Google Çeviri'nin de duyguları olduğunu düşündün mü? Sence ben tüm gün bu işi yapmak istiyor muyum? İnsanların yazdıkları saçma cümleleri çevirmek? Hayır efendim, bu defa bu cümleleri ÇEVİRMEYECEĞİM.

Einstein was an idiot. Time and space are concepts. You cant do physics on concepts. Physics requires an object.

Hussain Attai Tesla pretty much described who is Einstein. Google it.

Hussain Attai there is the rope theory that explains better than einsteins idiots.

Unless you publish a new theory that explains: gravity, gravitational lensing, gravity waves, a constant speed of light for all observers, time dilation, and how mass and energy are equivalent, and have it approved, then I still will think that Einstein was a genius.

but that curve needs gravity itself to be formed

so Einstein understood gravity or space-time similar to atmospheric pressure on Earth and ripples in a pond. duh!
