Greek Philosophy is still useful. greek science may be obnsolete but we stilll need to study them. Learning from past mistakes is still an important concept in science. Reading from old science also helps us appreciate how far ourk knowledge has improved.

So your mind and my mind think otherwise that what we are actually seeing.? Speak for your own mind. My mind thinks the Earth is spinning around at 1,000 MPH and moving around a sun at 67,000 MPH. Planets are far away. That is why it takes a certain time for us to fly there. This is the distance that we give it. Someone else 1000 Light years away might give it a different distance according to them. If we were in a black hole most likely we would be merged with all the other bodies. Light could not escape let alone anything else. So you are saying everything within a black hole can operate normally.? Also we could not see other Galaxies if within a black hole. Would make a good movie though. Within A Black Hole.

David Butler we are living on a black hole, planets looks so far cause cause black hole expand on his mass, and solar sistem spins cause black hole spins. Milkyway that we think we are living, is just dust of the black hole we inside, our mind and vision belive otherwise 👁

Because if it is the former, you are actually entitled to it, however wrong, idiotic, uninformed, narrow minded, shallow or stupid it might be - but if is is not the latter .... well - then you have not advanced the human race at all ... not in the slightest - you have then actually moved all of us back in knowledge, insight and understanding - and that's no help now is it?

It's what make them amazing they're never wrong. Humans make mistakes and lie but if you have enough parts of an equation you can figure out the parts missing. 2+3 is always 5 and if you know you started with 2 and ended with 5 you know 3 is the number missing. Just bc numbers get bigger doesn't mean the math gets less reliable it just means you've never done a 4 page equation to get a number everyone else also got
Ro Jay (3 months ago)
Bob Loblaw That happens a lot but I don't think flat earthers and others understand the concrete reliability of geometry and other equations.
Jared B (4 months ago)
I always like using the ancient view of the universe when understanding the difference between theory, hypothesis, and natural law. As well as demonstrating the difference between how science changes and how religious beliefs change. The observation that things move in the sky is a natural law: it's just so. The explanation of epicycles for planetary movement is an example of a theory. The theory explains the natural law and makes predictions: predictions which held true for over 1,000 years. The heliocentric model, starts out as a hypothesis, perhaps epicycles are wrong and things are not really rotating about the Earth. Tyco Brahe provided evidence to support this claim, but that's it. It's not until Newton that we have a new theory: a new explanation for the heliocentric hypothesis. Later, Einstein again reshaped our understanding of gravity by formulating the Theory of General Relativity. Here is where religious beliefs become important: religious beliefs change to support new evidence, but do _not_ make an attempt to reconcile previous beliefs (rather previous beliefs are simply discarded). On the contrary, science requires an equivalence principle. The new theory _must_ explain why the old theory appeared to be correct. Newton (or rather his predecessors) did this with the theory for epicycles (by showing how how the epicycles can be recovered by accepting the heliocentric view but changing the reference frame to Earth) and Einstein, likewise did this for Newtonian gravity with General Relativity. The new theory, while does invalidate the old, also explains why the old theory made such seemingly good predictions. Religion makes no such attempt. Once the old belief falls out of favor, there is no attempt to reconcile it with the new (aside from simply saying: they were wrong and didn't know better). In summary: a law is an observed phenomenon and a theory is an explanation for _how_ that phenomenon behaves. For Newton, this was that apparently all massive objects attracted each other. The theory explains how the natural phenomenon works. For Newton, this was his equations which shows _how_ , given this attraction, planets orbit the sun, and moons orbit the planets. And probably the most important part of a new theory is that it _must_ explain the previous; something often lacking in religious beliefs.

Get outta here! (5 months ago)
37rainman there ARE differences. The issue I have is that the Quran claims to be correcting the bible and I hear this nonsense about thw Quran which obviously plagiarized off the bible. Is it ok ? Did I come in here promoting tje Bible. No. The Quran doesnt have its own valuable stories only condemnatio for not following and believing it. Read page ONE.
37rainman (5 months ago)
+Get out:  Sorry, big fail.   There are differences in the Genesis and the Epic of Gilgamesh stories.    So if it is okay for the Bible writers  to take a Gilgamesh story and change it, it is just as okay for the Quran writers to take the bibles version and change it.   There is no difference.  It is trivial.   The Bible is the word of man in response to a belief in God.   So is the Quran.  Neither is the word of God.   That fact does not make the Bible less valuable, but it should make you begin to contemplate what exactly is the bible, and what it might be useful for.  If a lot of people understood these points, a lot of people could begin to grow up, and perhaps the world could be a better place.   Here is an example.  The story of Jonah.   Layers and layers of interesting, funny, valuable story.  If your discussion becomes whether or not Jonah could have survived in the belly of a fish, you have already proven that you are likely incapable of getting any value out of the story.  In the end, it does not even matter whether there ever was a person named Jonah, the story is still just as valuable and valid.

Quran 6:1 and 17:12 copied from Genesis 1:1-5
Get outta here! (5 months ago)
No. The issue I have is someone brings the Quran into a discussion about science and tries to use this to validate the Quran. What that person fails to respect is that firstly, copying from an earlier material and trying to claim ownership of the originality, as the Quran does, is outrageous ignorance. You can assure me that some of those stories came from other civilizations, but the Bible does not claim to have invented the stories. "In the beginning" isn't saying "In the Jewish Beginning". It's merely saying "In the Beginning". So the Bible doesn't take credit for "discovering reality". It just recites it. The Quran, had it done the same, would have simply continued on, not tried to erase what was said, retell it, and then act like the retelling is somehow based on some correction. The Quran however tries to say "In the Beginning, Adam was a Muslim" or that "the first language was Arabic" and other nonsense. The compiling of Genesis occurred clearly long before Moses as the names and events preceded him.
37rainman (5 months ago)
+Get out:   Your only "point" seems to be that the Bible is more relevant than the Quran, because the Quran might have been copied from previous material.     I can assure you that the genesis stories came from earlier civilizations than the Israelites.  Both of you are doing a pretty good job beating a worthless and dead horse.   If there is something in either of your books that can help the people of earth get along better, good, but that is their only value.  If these two books become only magical talismans to fondle, and supposedly get you to some wondrous place in the heavens when you die, they are worthless.  I can assure you that in Gods eyes, one is of no more value than the other.   There is no god in this universe that cares one whit about you and Rizwan's little concerns

It IS very very flat locally.  For instance if you mark a 1/2 mile long span on a sphere of 3959 miles radius.  The crown in the middle of that span is only 1/2 inch.    All of flatters so-called "proofs" revolve around the fact that earth is very large, thus very flat locally.   Their minds do not process geometry well

Your comment had nothing to do with the issue of why we might use one measuring system or another.  But I am glad you could get that rubbish out of your system. It is typical of naïve, envious, self righteous people in the world.  Some of us are looking for a day when we stop pouring money into your countries and let you fend for yourselves.  Here is one Canadians take on just the nonsense you spewed out.  It came out in the 70s.    Give it a listen.   https://www.youtube.com/watch?v=Lw2ysu1RWLA

"I belong to the technologically greatest country on earth. We use what we want" Yeah to make war against weaker countries really your country is the most advanced technologically speaking in the world, but in the matter of humanity is falling more and more, one day your country will ask for help for the weak ones. It's time for certain countries to be more humble.
37rainman (5 months ago)
At any rate if you cannot quickly change one to the other, you have greater problems than what system is being used.  I use "miles", I can just as easily use "kilometers".  I belong to the technologically greatest country on earth.  We use what we want.  Deal with it.

Show me proof that the ancient people weren't right!?
37rainman (5 months ago)
They were right.  Earth is flat locally.  Very flat.   But still a sphere of 3959 miles radius.  Deal with it.  Why do you think the ancients knowledge of the universe is more important or relevant than our knowledge of the universe?   Knowledge continually increases.  They knew that even back then.  If it didn't, you would not be communicating on your computer.  You would have none of the toys that you SO take for granted.   There is nothing high and holy about what the ancients understood about their reality.   If you make religions over stuff like this, that is your problem.  Those ancients would think you are stupid if you do.  The people who wrote the Bible would think you are stupid if you make some issue over helliocentrism, or the shape of earth.  Get over it, grow up, and move on.

Hello David, Don't forget about poor old Giordano Bruno who believed the Coperican model and lectured thus throughout much of educated Europe (against great ridicule) and may have done as much to plant the seeds of these ideas as anyone in his day! Also, we can't really blame the Classical Greeks for their model, very few of them had the education and time to really test it and . . . besides they did not have the Judeo/Christian bible which explains that earth is a globe that circles around the Sun.
37rainman (5 months ago)
You know, 4000 years hence someone is going to be saying exactly the same thing about our understanding of our universe.   "Cant blame"???  There is nothing to "blame" anyone about.   Btw, in the Bible, "earth" is not what you think it is. Look in the very first part of Genesis.   When they talked about "earth" they were talking about the land under their feet as opposed to the "sea".   No one was sitting around visualizing a big sphere or a big flat disc floating in "space".   They were living on something that apparently went in all directions forever.  That was their universe.   "Earth" was that bit of the universe that you lived on, surrounded by "sea". Nowhere in the bible is a finite globe indicated, and nowhere is a finite flat disc indicated.  And it certainly means little to us what they may have believed..  Btw, some history:  Bruno was not put to death for believing in heliocentrism.  We cannot find one person in history put to death for heliocentrism.  Copernicus worked a lifetime on heliocentrism and was deeply respected in his own time, he was so respected that a catholic cardinal famously wrote him a letter begging him to publish his findings about heliocentrism.    You can find the letter online.  Bruno was born well after Copernicus died.  Mouthy and disrespectful and sinful Galileo didn't die over heliocentrism, and likely would have never been put under house arrest if he had been a little different, more respectable person.  The classical greeks came up with the best, most revolutionary, most correct visualization of the world to date.  They would have known the Torah and other Jewish literature.  There is nothing in there that would have, or could have have helped then figure out their universe.

J Roger Trudel (8 months ago)
How can a person ever believe this? I know we were all indoctrinated with this science in our school education. But people, this is all fabricated assumed theoretical science. How can one ever measure a distance to the sun, moon, or stars? I use to believe all this as factual information. Today I'm beginning to question it all. The pictures shown here are all CGI composite pictures. And, how can one determine the chemical composition of a planet, let alone our own earth which they classify layers 4,000 miles deep, when we have only been able to scientifically core sampled only 8 miles of drilling depth? And the theoretical distances measured in light years? A car will disappear out of sight in about a mile distance and when you apply the loss of sight distance formula to a particular size object it disappears rather quickly, yet we see objects like the sun at 93 million miles out? Scientifically impossible. The moon at 250,000 miles out? Scientifically impossible. and the stars, hundreds of light years out, again with the loss of sight formula scientifically impossible? The formula being dx/sx = dy/sy. The left side will calculate the size distance ratio, then you can apply that ratio to the right side to determine the size or distance providing you know at least one, (size or the distance). Such as; how far is a five foot car that looks about 0.2 inches high as seen at 2 feet from your eyes. That gives you a perception ratio of 120. 120 x 6 feet equals 720 feet away. Or, if you know the distance to be half a mile away and the perception ratio is 500 then 2640 ÷ by 500 will give you the car size as 5.28 feet. When you look at the sun or the moon they both look approximately the size of a pencil eraser as seen at 24 inches from your eyes. Now do the math.
SamytheGreek (7 months ago)
That will only give you the distance of 1 light year, they claim billions of light years, I don't think they can do it.
SamytheGreek (7 months ago)
They can do it but there is a limit, they need the distance of earth's orbit to measure as far as 1 light year, that I can believe but they claim the have measured as far as 18-20 billion light years, that I can't believe.
Dennis Dougherty (7 months ago)
Well David, I think Mr. Trudel is on to a good point with this 'loss of sight formula' its just that he gets a little ridiculous with this car analogy. We know you can see a car farther away if the lights are on at night. Stars work similarly. And as to this geometry, it works well if you know either the distance or the size of the object. These great stars and galaxies are most likely billions of 'earth light years' away but we don't know for sure. We also don't know how fast light travels (or even if it travels straight) in outer space do we?

Nasa and all there scientist would never find any other planet because they don't have the ability except lying. In this Documentary its mention that this is ancient idea that universe is full of life and the earth revolve around the sun . This is the open Challenge of This Book.The only book on this earth from last 1400 years still the same each and every word. First Its mention no where in Quran that earth is revolving around the sun. The Holy Quran says in chapter (36) Vers-38,39,40 [ "And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming.] I request the Nasa and all the scientist please do not destruct human dignity by saying and claiming those things which you all don't have any ability. God has made this Earth for us with all the facilities which we are using enjoying. we have put human in terrible situation most of the people are lake of basic necessities and you want to conquer galaxies . Sun Moon and all other stars are only to remind you about the creator. please stay on the planet earth and do some thing cording to your ability and leave what ever out of your reach.

Junsi27 Chin ... u only can see his creation around us from the time of beginning of prophet Adam our first fathers till now today we live together in this world moving around us.

Back when I was in school we never got to watch informative videos like such, it would of made school so much better with visuals like this, but then again maybe we would of thought in our heads it was more laid back so I would of forgot more, Idk. If the teacher were to give the heads up about the tests the following days then that would've stuck better.

If I were a science teacher, I'd feature one or two of your videos per week, and have a test the following day.  Your the best!

These are a superbly edited and presented series of documentaries, the perfect balance of level and explanation. I'm fairly advanced in this area but the summaries here have added measurable background information and clarified facts, thank you very much.
David Butler (8 months ago)
I did put them all on a blue-ray disk, but it was just for my children and grandchildren. Nothing I do in this arena is for sale. Thanks for asking. I love your note.
Andrew James (8 months ago)
I have just watched it, am progressively working my way through all. Do you have this set available for sale in HD / on DVD? As a gift for either my 77 year old father, (a life-long amateur), a 16 year old son (looking for somewhere to focus mental energy) or my 24 year old PhD daughter (who is in at least this way a chip off the old block), they would be considered by all a bargain. I really cannot recommend this series enough, thoroughly enjoyable; presentable to audiences from near beginners or just more information and examples to serious amateurs, it's the best out there by a margin. I'd just like to point out to others reading this that I consider myself a low end semi-expert, I was a guest evening lecturer on deep space a a significant college in England, and have tested my own calculations for distances, magnitudes and Supernova masses etc. but still many points are clarified by this series - the best I've seen. Thank you again,

Mr butler, can we see stars from outer Space? What do you think about intelligent life in outerspace. Great videos thank you
David Butler (9 months ago)
Ferdinand, You can see stars better from space because the atmosphere is no longer in the way. The pictures from the Hubble Space Telescope are the best ever taken. You'll see a lot of them if you continue with the 'How Far Away Is It" video book. I'd guess that there are intelligent being out there, but they are too far away to ever communicate with us.

Why centripetal force as opposed to centrifugal force? As I understand things, centripetal force is the sun's gravity pulling the Earth towards the sun. If there was no opposite force, Earth would be sucked into the sun. Centrifugal force is the force that opposes the sun's gravity and prevents the Earth from falling into the sun.
David Butler (9 months ago)
Your are right. The real force to the center is 'centripetal'.

it was not Coppernicos,but Aryabhata hindu astronomer mathematician and inventor of zero who proposed the heliocentric model in year 500. 1000 years before europeans.
beryl peril (8 months ago)
While a moving Earth was proposed at least from the 4th century BC in Pythagoreanism, and a fully developed heliocentric model was developed by Aristarchus of Samos in the 3rd century BC, these ideas were not successful in replacing the view of a static spherical Earth, and from the 2nd century AD the predominant model, which would be inherited by medieval astronomy, was the geocentric model described in Ptolemy's Almagest.
beryl peril (8 months ago)
As mentioned, Aryabhata advocated an astronomical model in which the Earth turns on its own axis. His model also gave corrections (the śīgra anomaly) for the speeds of the planets in the sky in terms of the mean speed of the sun. Thus, it has been suggested that Aryabhata's calculations were based on an underlying heliocentric model, in which the planets orbit the Sun,[33][34][35] though this has been rebutted.[36] It has also been suggested that aspects of Aryabhata's system may have been derived from an earlier, likely pre-Ptolemaic Greek, heliocentric model of which Indian astronomers were unaware,[37] though the evidence is scant.[38] The general consensus is that a synodic anomaly (depending on the position of the sun) does not imply a physically heliocentric orbit (such corrections being also present in late Babylonian astronomical texts), and that Aryabhata's system was not explicitly heliocentric.

I just saw the classroom aids for this segment and although some are similar to scenes from this video, there appears to be more coverage of different topics as well such as dwarf planets and asteroids. I can't wait for the new video to come out! But a concern is that all the views from this video will disappear when you upload the new video in its place. This already happened with the Earth video. Is there a way to prevent this from happening?
David Butler (10 months ago)
All the 'Classroom Aids' for the segments of "The Earth" are still there. These will remain as well. The idea is that the classroom aid playlist will be the music free version of the full video for those who do not want music.

Not here in India. Indians knew that Sun is at the centre with planets around since the day one (As mentioned in our ancient books).

I understood that they came close, but didn't consider the Earth a planet.

can u tell me... why Venus and Urenus revolve Anti-Clockwise
David Butler (10 months ago)
All planets revolve around the Sun in the same direction. This includes Venus and Uranus.
Parv Bhadana (10 months ago)
yep... thnkx Sir... i wnt to knw how our Solary system Revolve...
David Butler (10 months ago)
We don't know why, but the current thinking is that they started out with the same spin as all the others, but then off center collisions with very large objects changed the direction of the spin.
Justin Casar (10 months ago)
Damn I was thinking the son was more like 99.6% of the total mass of the solar system. I guess my calculations were a lil off.
