What do you mean by non-zero energy? And how are thinking of momentum in your description, I know p=MV but are you thinking of it differently to make the explanation clearer in you head? Thanks for your help I think I'm close to understanding.

Well I'm asking because Einstein theorized that outside of our universe there is no spacetime. Then you have so many theories of multi verses and how our universe could be a bubble, is that theoretical bubble just a group of matter or a bubble of matter and spacetime?

E= mc2

What do you mean: four-momentum?

So this is what I think all this means. When calculating the energy of rest mass you times the mass by C, but you also have to times mass by P and the P would be the same as C so squaring C in e=mc2 doesn't make the final calc higher than it should be. Or mc^2 times mp^2

Points in time.

I have a hard time comprehending the theory when I apply c2. Maybe a better question would be how does light apply or how is energy not mass?

Since E=mc2, that means that mass is energy and energy is mass right?

I'm in 10th too. Space-time does act like a force field, I knew that but I needed to hear it in the way you said it. Some of what we have been discussing is string theory and how the energy that makes the strings vibrate means they won't pass through things, instead they'll act as a force or a...

That makes sense, thankyou

I found this helpfu . Very simplified, it sounds like energy warps spacetime because E=mc2 but a mass does not have to be solid to do so. In other words it can still pass through things. Is that right?

So why doesn't spacetime go through matter unaffected?

I guess a more precise question would be why does mass effect mass even if it can sometimes pass through things like neutrinos do or maybe how the strings in String theory might?

Whatever spacetime be made of strings or some other erotic substance it seems that it doesn't have mass so what causes it to warp around mass, shouldn't it pass right through?

So when subatomic particles are going near the speed of light the amount of energy creates a measurable amount of more mass?
