I guess that makes sense, thanks. I was wondering if it might have been something like the theories of what might happen much later in the universe's life, where things eventually get so far apart while still accelerating that light can't travel between them. But it couldn't be something like that if we can see the other galaxy, right?
- thisBrian 7y agoThat still holds true, eventually nearby clusters will go beyond our "observable" view.
- gpderetta 7y agoAt some point in the far distant future the night sky will be black, with everything being beyond our visible edge of the universe.
- Filligree 7y agoWe can see light that was emitted from it billions of years ago, before we split apart. Similarly, they can see light that ours emitted billions of years ago. They can never be affected by anything we do now, or vice versa. This doesn't make it "read-only", though -- we can't read it either. All we're seeing is their distant past, back when we were mutually able to reach each other.
