The distribution of matter that because galaxies and such was spread so thin, that it is now basically equal in every direction.

I’m still not understanding. I thought everything started at a point and is expanding, space itself is growing. Suppose there were two shrubs close to gather at the beginning, about a yard from the edge of everything. Space is growing, now they’re far apart. Did the distance between those two shrubs ever increase faster than c? Is it necessary?
Is there ever a case where information travelled faster than light?
