Why humans cannot see the universe.

[rununder]

I’m supposing that the spacetime curvature causes gravity, and not that gravity causes curvature.

Basically physical attraction between objects, movement, and gravity are the result of “falling” from one location to the next, according to the curves in spacetime. It’s like rolling downward from the top of a mountain, you have 360 degrees of movement to fall horizontally yet one direction downward. Spacetime is more complex than this type of 3d geometry though. There ought to be much higher variation of travel when talking about movement in 4 dimensions. More freedom of movement.

Curvature of spacetime is caused by acceleration, expansion, and retraction of concentrations of energy. An object doesn’t have to be massive in order to severely affect spacetime.

Temporarily accepting the notion of bending space; why would the bending of space cause masses to attract (gravity)?

It causes a kind of hill, and the objects have some tendency to roll in that direction, but it’s not bent like a bar of metal.

Saint James is right to ask that.

Humans believe that things only fall “down”. That’s not true objectively. It’s true on Earth, generally, yes. Things “fall” toward Earth. But out in space, nothing falls. Or, things fall left, up, right, down, forward, backward. Things fall every direction, in space. So this applies to all objects and gravity.

Falling in space is the same as the “downward” motion in spacetime, where physical reality is bent and curved. Gravity is merely the act of “falling” toward a concentration of mass.

The problem is, falling is not always down. Sometimes you fall upward, left, right, across, forward, backward.

The curvatures in spacetime dictate the direction of gravity. It’s not the other way around. It’s not gravity bending space time, necessarily, inasmuch it is curvatures in spacetime that indicate where gravity is, and why it is there. In fact, this is the only reason we can even discuss the existence of blackholes and other spatial anomalies.

There is something there, but human perception cannot recognize it.

We’re looking at gravity backward. The curvatures of spacetime should be investigated, not necessarily the massive objects of gravity.

1. first part is pre Newtonian talk.
2. most things about gravity are describe in relativity theory already and therefore are not a mystery, well only to lazy people who doesn’t bother reading it.

James please re-read what I wrote, you have a bad preception of my words.

If planet A and B has X distance, a gravity wave will distorce the fabric of space and time, and one may assume the possebility of X being shortened by the gravity wave, therefore the mutual pull will increase just a tiny bit.

Things roll on a hill due to the gravity pulling them downward, not because of the hill.
If the curvature is “the hill”, then what is pulling them “downward”?
If the gravity is what is pulling them “downward”, what is causing the “hill”?

Please try to understand two things;
A) I understood what you said.
B) 80-90% of the time someone says that the other person didn’t understand, it is actually that the person speaking failed to understand the other person and presumed the opposite.

Your answer did not relate to my point.

Your answer did not relate to my point.

My answer was “I think you missed my point”

Your response was “sigh”, followed by a repeat of what you already said… that missed my point.
Perhaps think a little more about that (B) in my last post to you.
