Einstein or Newton

And more directly to your last question, nothing is pushing the object into the fabric. The fabric responds to the object's mass. It is repelled, like two magnets

Nobody knows.
You can use the Einstein Field Equations to determine the spacetime that results from some distribution of energy/momentum, but this does nothing to inform us of why this happens.

Sal, space-time is 4-dimensional. The two dimensional "fabric" is something of a metaphor for understanding the effect mass in space-time. And the objects don't have to be "sitting" "on" space-time. They can be below or beside it, it doesn't matter. What matters for the purpose of understanding h concept is that they are essentially points on a plane and the greater the mass, the greater they distort the plane. The balls on a blanket is just a way of isolating and understanding the effect without breaking your brain trying to apply it to 3 or 4 (or more) dimensions.

The 3rd dimension is just a combination of length, width, and height, and the fourth dimension is a measurement of change or movement of three dimensional objects relative to each other, like the cycle of the sun relative to the earth divided into units. Starting from a beginning and end defined by visual marks like location or night. So its easy to understand up to the 4th dimension, but beyond that is foreign to me.

So is substance that's interacting with the bodies of mass 2D or 3D? If its 2D like the models represent then I think that's irrational to believe as a cause or explanation of gravity for multiple logical reasons.

If its 3D then that's closer to Tesla's explanations because those "imaginary points in space" that define the "fabric" would be better defined or understood as electromagnetic vortices, not just "space or imaginary points of reference".

Your analysis goes hand to hand with your pro-Muslim debates

It's all shit, go light a trashcan on fire,.

Blahblahblah I don't understand the theory I believe in because its irrational to begin with, so I make up some grandiloquent nonsense as if I know what it means, then reply with useless insults because I lack the ability to think for myself.

i wonder if toehammer notices all the ants that scurry about his feet...

If I have seen further it is by standing on the shoulders of (Gi)ants

I was going to post a response to Daywolf and Saludeen, addressing points one by one, but I just don't have time. I am getting a new postdoc in the lab next week, just got a new PhD student, and am trying to hire a research assistant. Instead, enjoy this fun video of a 2D representation of space(time) as a tool to understand orbits. https://www.youtube.com/watch?v=MTY1Kje0yLg I used to wonder some time ago why planets orbited primarily in one direction... this video actually shows it... fun stuff, you can learn a lot from playing with physics analogies.

However, there are lots of questions and comments in this thread that are very difficult to answer/respond to unless people know a bit about quantum and general relativity already. It is tough to visualize 3D spacetime warping, so 2D does a good visual job. 3D vector spaces are challenging to visualize... took me until the middle of grad school to be able to see them in my head. The weirdest thing that comes out of general relativity is that the mass-energy is the source of the field, and the field is the source of the mass-energy... no analog I can think of anywhere else in science. Also, when you mathematically traverse the event horizon of a black hole, the time and position coordinates exchange places in all physics equations. I have no flipping idea what this means.

The other coolest thing I have been reading about recently is Erik Verlinde's theory of entropic gravity, basically that gravity is not a fundamental force, but just an entropic force.

I can't make long posts any more, sorry.

cant wait for proof that 3D is just perception so the Saludeen's of the world melt into a puddle.

we're all stuck on a wall together, theres a force across from the wall called gravity. this could be what a dimension is, if a dimension requires, or acquires gravity as a side effect of its creation, to be birthed. each dimension would be a wall layer with a gravity hole across from it.

Woke.

somewhere in the universe trans-dimensional beings are entertained by studying the human nervous system and its limitations and explanations of time and space.

Saludeen is a big hit on Saturday nights at Xenu's crib.
