It's interesting that we can presently see two galaxies that will never be able to see each other. They will drift out of Earth's observable universe before each other's light would have a chance to reach the other. Dark energy & accelerating expansion is weird.
- Tepix 5y agoChances are you can make a string of thousands (trillions?) of such galaxies. We currently have no way of knowing the size of the non-observable universe.
- lelanthran 5y agoWhich two galaxies?
