(17,505 posts)Actually...we don't.
Velocity is different from expanding space. We assume we see red shift because of expanding space, not velocity. That's why eventually things will be moving away from everything else faster than the speed of light.... because it's not velocity.
And we have math to help us realize these concepts... and we know math is real.
And the expanding is everywhere. The space between you and your PC is expanding. The space between the atoms in your body is expanding.
And space expanding is not like a balloon being blown up either. The universe is not expanding into some kind of space outside it.... it's just expanding... period. But that is almost impossible to "get" because our only experience with expansion is into the space already created by an expanding universe.
"The weak link is the assumption that velocity is the only thing that causes red shift." No more weak link!
