If the universe is really expanding, where is it expanding to? That's something I have yet to understand.
BTW, I'm not high.
Neither am I nor was I when I made that post.
Nobody knows. There are many theories on what the "bounds" of the universe may be, but what I was referring to above was matter. Space and time may have no boundaries. The matter in the universe seems to be expanding from our viewpoint. It's not entirely certain that is true as something may be tricking us that we don't understand. And even though we can't see it, more likely than not, the universe is far, far bigger than what we can see (and what we can see is HUGE).
I'm paraphrasing this, but there's something along the lines of the Chimpanzee analogy, in that, the smartest chimp can't understand what the dumbest human can, no matter how much it studies or learns. Its postulated we've rapidly approached this in recent years in terms of human intelligence. We can continue to observe, but we are, perhaps, a large leap away in intelligence from understanding.
