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.

      well what about the other theory the says gravity is actually a force , which explains all of the same things?

      Instead of marble he should use some metallic object which can develop current by it's own

      Because each planet has also metallic property and by rotating they develop current and so magnetic forces and hence do not looses energy and so keep on rotating in the solar system

      Bends time. people it's this!! Some things are denser than the medium they are in. Ie; a rock is denser than water so it sinks. What this goof is postulating and trying to warp those kids minds is hocus pocus theoretical BS. his own crappy experiment just failed. Wake up folks. Please

      Friction is why it looses energy but in space there is no friction

      My guess is that even tho it might not seem, our solar system is costantly moving. Even the Sun is moving. In this representation the most constistent mass is still so the little balls are losing energy. But I'm not an expert nor I study phisycs so I might be wrong.

      Sadly professor i belive you might be wrong i am not a scientist i am only a person who adore reeding nature
      Black hols one kind of it may be a stage after super nove or after the dwarf stage with extrem more heat & gravity
      Or only extreme gravity i could not under stand the protrudeing element you did if you want to understand space wright then it should be in water ask the astronauts on the net the nearest feeling in space is more to the swiming than the fabric deferent lows deferent physics

      This is a beautiful teaching device, to give students the sense of understanding space/time ... which cannot be understood. In reality, this is not what is happening. The fact is, we don't know what is happening, in terms of physics and math, regardless of how Einstein explained things in human terms. In physics, we have mathematical equations, that at best, can predict physical behavior. To attribute grand schemes of human imagination to these equations, is tempting ... but not accurate. (The same goes for quantum mechanics. When someone explains quantum mechanics, in human terms, they are explaining their explanation, and nothing else. It is as flawed theory that makes little sense, yet has predictive value.) -- The reality is that this video is a sheet in a classroom, that crudely mimics a bit of what we see with gravity, yet it does not really demonstrate anything beyond what it is ... a sheet and balls interacting in a room. -- If you see this and say, "Oh, I understand space/time"; you don't. There is nothing in the math of space/time that says anything "warps," - the word, "warp" is a human attribute. Math does not talk or use the word "warp," and that's important to understand. The math equations of space/time do not explain anything; they predict experimental outcomes with utility, yet with flaw. -- In teaching, we should have the courage to explain that we don't really know. An over-explaining approach gives students a false idea of what physics and math are. We should not anthropomorphize (or reality-morphize) equations and pretend to students we know something we do not know. -- Further, it is entirely possible that math, a human construct, does not accurately describe anything. Most likely another system of prediction and discovery, more accurate and advanced than math, will replace math, as conscious beings evolve and improve our awareness. Reality is not math or the way humans think: this is like a dog thinking he knows what reality is because he has discovered some predictive schemes to his world ... and dogs do, in fact, have predictive explanations of the world that are "accurate" and enable them to survive, as does an ant. -- A student will know much more about reality, if we clearly explain to them what science and math are, and are not. It is Ok, to tell students that we do not know, that physics does not explain what something is. An honest, "we don't know" will lead to much better science and further discovery. -- There is a grand difference between predictive equations and "knowing." The reality may be that reality cannot be "known" in the sense we seek to know it. The idea of "knowing things" may be a flawed and egocentric construct that is produced by a lack of evolved intelligence, especially if we are the ones creating reality. If we are the one's creating our physical reality, then seeking to know what we have created will always be a false and fruitless pursuit ... when there is nothing, in reality, to discover but ourselves.

      Me. 2am. Somewhere in Ghana, West Africa. Questioning my existence while reading this entirely.

      Knowing, Even the top scientists, astronomers, physicists etc, with all their mathematical equations, don't "really" know how or why we exist and what we exist on..

      Makes me feel so small😶

      So this gravity model says: the balls are attracted due to... gravity LOL ! Because balls roll into cavities due to the force of gravity: the reaction force of the support is not directed vertically upwards, counteracting gravity, but perpendicular to the curvature of the cavity (as a radius), which means the sum of the forces pulls the body into the cavity. So, to explain the gravity we should have... gravity LOL. It seems modern physics is totally mathematical fantasies irrelevant to the reality. And stills no any evidence of curvature of spacetime, like no evidences that space is something more than emptiness.
