>>112403341) If the Universe is infinite in size then it must also be infinite in depth because of physics symmetry requirement, furthermore, if the Universe is infinite in size then the odds that our scale would be as close to the "quantum foam floor" as we are would be essentially impossible given the infinite number of other scales we could have optimized into. So, the vastly more likely solution is the Universe is infinite in both directions and we can only detect down to the quantum foam.
2) If the Universe is infinite and the speed of light is constant, that light speed acts as a conversion factor between different time scales. In short, the larger the scale, the slower it moves relative to smaller scales, and time is simply a measure of energy through space. i.e. large scales are slower and small scales are faster through time.
3) If smaller scales are faster through time - and they must be if light speed is constant, and the Universe is infinite - then this gives an elegant explanation for why angular momentum of subatomic spin is recorded as being faster than light - it's because its literally traveling faster through time.
4) The recorded shapes and distributions of atoms, including their electron clouds, are virtually identical to the shapes and distributions of galaxies, and the distribution and number of galactic solar-clusters is essentially the same as the distribution of electrons in the electron shells.
5) The galactic and atomic scales are essentially mirrored. You could blow one up, or shrink one down, and they would essentially overlap each other. They represent the fractal unit, the point where the Universe begins repeating in pattern.
I could go on, but this is a good primer.
