I know that the universe is expanding since the beginning of time or at least the beginning of the universe it self. So I was wondering if the universe has always expanded evenly (some parts getting bigger while other grow not as fast) and if it doing so now?? The example in my head is like dropping die in water. The die on the outer edge will dissipate faster than the die in the middle of the drops. Or even some other kind of form of the idea.
