If the universe is always expanding, that means that there are places that the universe hasn’t reached yet. What is there before the universe gets there.

Question

I just can’t fathom what’s on the other side of the universe, and would love if you guys could help!

Answer 1

One thing I was told, similar to the ballon metaphor, was this: Imagine an infinite ruler. Like the one with inch/cm markings. Just infinite long. And now expand this ruler. You clearly see the markings get farther and farther apart, the bigger the ruler gets. But it’s still “just” infinite.

The universe is already infinite. Just because it’s expanding doesn’t mean there can be something beyond this infinity
