Everything is too far away and the speed of light is really, really slow compared to the size of the universe. And to make matters worse, the universe is expanding.
We may leave Earth, and might even manage to leave our solar system, but we’ll never leave our galaxy.
- syssu 5y ago"The universe is expanding"..I would ad "faster than the speed of light". And that some galaxies that we see today we will not see in the future, as the space between us will be traveling faster than the light they emit can travel.
