1) Well, yes, it took some time to cool down and stars to star fusing, but there was still an expansion pressure energy from time 0. 2) Yes, mass is energy in a localized form, however, mass and energy do not have the same properties. In context to the OP, mass produces attractive forces upon...

If it all started with a big bang of incredible density and energy, does that mean there must be particles that can travel faster than light? How would anything escape the grip of that kind of gravity? I was under the impression that at a certain threshold of mass/density, it turns into a...

One of the things I have yet to come across in the explanation for the expansion of the universe is the effect of light... Most all of the matter we observe out there are stars - fusing nuclei and radiating EM energy in incomprehensible quantities... And this has been happening since the dawn...

I appreciate the attentiveness and thoroughness to the answers from you all. I humbly admit that some of what has been described with the terminology used is a bit challenging, however, I still feel unfulfilled to a satisfactory answer. Perhaps a different approach to my question is in order...

Nugatory, If these forces, and light, are expected to behave this way in 3-dimensional space then how does that expectation fit in with strong and weak nuclear forces?

Ok then. When spacetime curves, how does this "curvature" interact with matter to apply a force to make it move? To say that mass affects the spacetime around it in such ways, does this not also infer that spacetime must have a structure to it as well? And if this is the case, what is the...

1) If the idea that gravity is a curvature of space that causes objects to move towards each other then would it be appropriate to say that magnets do the same thing to space? 2) Does it seem a bit coincidental that both gravity and magnetism operate by the inverse square law or is it possible...
