Every visualization I've seen of t=zero looks like an explosion, rushing out from a point. But in an infinite universe, t=zero must also have been infinite, just a much smaller and more densely packed infinity.Indeed, this is rarely conveyed in pop descriptions of the theory.
The explosion from a point seems to be the only choice of methods to convey it with pictures since pictures necessarily are pre-existing space into which the illustrated thing must bang. So forgive the visualizations which effectively depict a finite size (presumably what is now the visible) universe that starts effectively at a point and gets bigger, instead of an unbounded universe compressed to an arbitrarily high density.
I also did not wade through the long video, only skimming it briefly. Policy of the site is to make your point here. So what exactly do you propose that 't=zero' was like? The video seems to harp considerably on the matter/antimatter (+/-) thing.
So I animated a visualization of an infinite and perfectly ordered universe at t=zero, and then let that universe play out, to see what would happen.What rules do you think you're simulating? The early universe was not perfectly ordered, else it would still be perfectly uniform. Quantum mechanics doesn't work that way.
