RE: Are we thinking about the big bang all wrong?
This is a complex thought process and makes me re-consider the idea of infinite points. I wonder about the infinite velocity though. Space can accelerate away from us faster than the speed of light, simply because there's more than one direction.
If we had multiple points moving away at lightspeed, then the velocity compounds to something far beyond lightspeed, no?
Would be great to get your buddies involved!
If lightspeed is constant, and the distance between origin and destination increases due to spontaneous eruption of space between them, then lightspeed would appear to slow to observers keeping an eye on it. But it's not space that erupts - it's spacetime.
Since speed is a function of both time and space, lightspeed appears constant because both time and space are actually one thing. Although the light now has more space to traverse, it also has more time to traverse it. The speed of light remains constant.
