Dan Burns explains his space-time warping demo at a PTSOS workshop at Los Gatos High School, on March 10, 2012. Thanks to Shannon Range from the Gravity Probe B program for creating the original demonstration which he shared with Dan in 2004.

Yes the orbiting is nice, but I have a question. Gravity is explained as "objects following the curvature of space" but curvature alone cannot cause acceleration. In this simulation the downward force of gravity causes objects to orbit -- this would not work on the ISS. Isn't a force necessary to make objects accelerate in curved space?

but i have a doubt sir , the more massive object bend the space more , is that right sir in this clip you are moving the marbles towards the the star ,but in reality what moving the objects towards star , and if you keep the marble without disturbing is will go in straight line towards the star , and what force preventing it from merging, please give me an answer sir .than you.

The experiment is flawed. Most of the things happening on the blue sheet are influenced by earth's gravity.

Question? If an object like earth bend space, in which direction the space is bend? In the video the space is bend downward which make sense if the space is flat like a lake.

'Objects are not influenced by gravity, but follow the curvature of spacetime.' Not true. All the objects in the video are influenced by real gravity. If you tried this experiment in a zero gravity situation, it would not work.
Lew South
Lew South Day ago
There are at least 2 reasons why this “demonstration” actually fails to demonstrate anything about the nature of gravity. First: The balls wouldn’t “attract” each other if not for the local gravitational field, i.e. exactly what we’re trying to “explain”! The demo obviously wouldn’t work at all in so-called “zero gravity” (i.e. freefall). Second: The “explanation for gravity” is NOT that “matter bends space”-as said at the start of the video-but that matter (etc.) curves *spacetime*: This distinction is crucial. The term “spacetime” may be used throughout the rest of the video, but no notice is taken of the fact that the curvature of the elastic sheet is purely spatial. Additionally, I must point out that the dark energy illustration is just nonsense. Dark energy does not curve spacetime (or space) “in the opposite direction” from anything else-in fact, that’s not even meaningful. (See intrinsic vs. extrinsic curvature.... Hmm, come to think of it, confusion of those two is a 3rd reason that the whole thing doesn't work.)

So how come we don't fall out into space from all directions?? And if we spin how come smoke from a volcano won't leave a trail like a plane..?? And if the plane flew the opposite way why doesn't the smoke follow ??
Puberty Assosiation of New Mexico
I hope you're joking tho or this is gonna be the biggest wooosh I've ever experienced.
Puberty Assosiation of New Mexico
First, very immature commenting "FLAT EARTH" over 5 times. But anyway I'll debunk your points. The reason we do not fall out into space from all directions is that gravity overpowers the spin of the earth. Second, everything is spinning with the earth, including the air. Volcano smoke doesn't leave a trail because it's moving with the earth.

I have a very stupid question for anyone familar with cosmophysics, which I have always been curious about. I know there is no up and down in the universe. Then, I have to guess gravity is supposed to affect materials, in any possible directions (correct me if I am mistaken). So, my question is: Are the planets in our solar system revolving around the sun "concentrically", in a way that the sun and all the planets can be drawn 2-dimensionally? Or are the planets revolving around the sun like electrons revolving around an atomic nucleus? This video seems to be showing the former is the case, but why? Add: To clarify, I understood what the professor is explaining. But I still don't understand why the gravity of the sun (or of any other greatest star in their own system) distorts the space in that particular direction, thinking that there is no up and down in the universe.
Jose Luna-Bojalil
You are right that gravity affects objects in all possible directions. The reason planets orbit the sun in a 2D plane has to do with how the planets were formed. This article explains it well: www.forbes.com/sites/startswithabang/2018/03/01/why-do-all-the-planets-orbit-in-the-same-plane/#50f8b57856c6

I can see one theory that Mr Bern's dont have right . When Mr Bern's said that objects rotate around an object in different directions 90% of the time they all end up going in the same direction ! That may be true only if all the objects are the same size and the same mass . Here is the problem when masses and sizes to become different then Mr Bern's theory dont count . As in his demonstration @ 7:52 . So here is the proof . If your largest and heavest mass was going counter clockwise and the lightest and smaller object is going in the op direction and if they both hit each other dead on the the heaviest object will dominate the direction . The only time when a smaller mass and size will ever to over rural the larger mass is when the smaller mass has a faster speed in relitive or = to the mass of the heavier object . So if the heavier mass is four times the height of the lighter mass then the lighter mass has to achieve at lest 4 times of speed of the heavier mass . Then there is another equation the size differences have to be accounted for . Sorry to bust Mr Bern's theory but hell . It dont talk some one smart to figure the problem . It's pretty much like this . If you let a 400 pound man punch you right in the face with his fist and then you have a 40 lb person hit you with his fist in your face ! Which one of those fist going to hurt worse and do more damage ? Einstein is not that smart at all and still he did not prove anything . The Germans had it right before Einstein ever thought about it .

So which way is the "gravity". It's should be bulging as much from the other side than from this side. Or is that too complicated to figure out. This might work if there is a universal law that the gravity is just one-sided. Something is flawed with this theory.
Jose Luna-Bojalil
This is just a simplified analogy so that students can understand. The 2D fabric is supposed to represent 3D space, so you're correct that it should be bulging from the other side as well, that's just much more difficult to visualize.

Is there some fourth dimension influence in gravity. Like this works with force downward (3d influence).
KaiTMR Gaming
KaiTMR Gaming 23 hours ago
There is no way for a three dimensional being to infiltrate the fourth dimension. Therefore there is no way to see what happens during the influence, or if there is any influence at all. QUANTUM MECHANICS ARE CONFUSING!!!!

Griffin Kowash

I'm confused by his explanation at 2:45 for why all the bodies in the solar system orbit in the same direction. I thought this had to do with conservation of angular momentum during the Sun's formation--all of the infalling matter formed a rotating circumstellar disc, after which the planets and asteroids and other bodies coalesced. His demonstration makes it seems like all of those discrete bodies formed traveling in different directions. Can somebody help clear this up for me?

Ironic, Time brings context to scientific history, time is religion and not of space or G. Space is not a place where nothing exists, existence offsets its existence, nothing is exclusively relative in an abyss of space. The one thing that was sensible is when he said the marbles do what they want, this contradictory abstraction implied real failure of relativity in space time.

What a hoot. He is not demonstrating attraction between any two of those balls, nstead between any ball and the center of the Earth. The second ball simply creates a path which has a vertical component, so the first ball can move. If the table was covered with a glass top whose normal vector points to Earth's center of gravity, then nothing will move, yet the gravitational pull still will be exerted on each ball.

But space is 3D, so it warps around a heavy object in every direction, whereas in this demonstration space is 2d and warps only in one direction, towards the base of the heavy object; which is why the smaller orbiting objects can only orbit on one plane (the surface of the flat 2d sheet of Lycra). In 3D space, what determines the plane of the orbiting objects? How come they all still orbit on the same plane around the heavy object as opposed to orbiting around its equator or from pole to pole?
