"This is too much!"
Well, technically there is nothing outside the universe for it to expand into. As far as physics is concerned, really we can treat anything beyond the Hubble distance as if it doesn’t exist either, since it can’t affect us.
Perhaps the universe is not expanding at all, but all the matter inside the universe is shrinking...
Anybody remember learning about the oscillating universe in school? The idea was that the big bang happens infinite times, matter and energy are always slung way out (universe expanding), the expansion slows from gravitational attraction and eventually reverses, then when all the matter and energy are all in one point again another big bang happens. Over & over & over.
That was the atheists explanation to science geek Christians when the Christians pointed out that a giant explosion would create so much chaos for a universe that seems to be so ordered like it was tailor made for advanced life to exist somewhere. Atheists: Well, then it must happen infinite times so that it's just right at least once.
Then the Hubble telescope was made and showed the universe's expansion is accelerating, not slowing down. Like the big bang was a one time event, not infinite times. Thus, the chaotic event just happened to sling out all matter and redefine physics just right -- the one time it happened.

At least Brooklyn is not expanding. Well, at least for Billions of years.
“If the universe is expanding, what is it expanding into?................”
That is the ultimate, inexplicable mystery.
We’ll never know the answer. There’s not even a plausible theory/bullsh!t story for it.
That’s like “What do they ship Styrofoam in?”
