Or is this "just" a model?

I know. That's why I put it in quotation marks. But it's not perception. It's apperception.

Vote will have to decide. I don't know which is best.

Because according to General Relativity, the stress-energy density is related to the curvature of spacetime. In other words, a curved spacetime is equivalent to presence of mass-energy. One can either say that mass-energy bends spacetime, or bent spacetime is mass-energy. The tensor relation between spacetime curvature and mass-energy is G = 8 pi T, where G is the curvature tensor of spacetime and T is the stress-energy tensor.

objects don't bend space-time. The force responsible for bending space-time is actually Gravity. Every object we in counter like stars, planets, and comets have gravity. Think of gravity as an upside down tornado. When a mass less object approaches it like photon(light) the particle is bend. This usually causes space-time distortion or the bending of space-time.

grasping well-known Relativity at a conceptual point is basically previous all yet an rather few. There are mathematical suggestions that are already very complicated, yet previous it quite is, particularly, inaccessible. The trampoline analogy is an rather simplistic 'tale' that, as you believe you studied, quickly breaks down. The curvature of fourspace isn't for the faint-hearted. In his time, Einstein theory there have been some others who understood his theory.

We don't have a good answer to this question. We have observed that massive objects bend light, but we don't have any perfect theories to explain it.
Ancient man knew about gravity, and we've been trying to understand it ever since. Newton was the first to be able to describe it mathmatically, and Einstein was able to extend our ability to reason it out. Yet neither of them 'knew' why gravity works the way it does.

Our space time continuum is already bent and actually patterns a bubble as in most universes but some can have other mechanics depending on their particular physics.

Don't know, don't think anyone does. I believe objects with mass bend space, not tjme, though. Maybe I'm wrong.

It is a model, but I wouldn't say "just". All human perception is a model.
