The Universe

A thought occurred yesterday. I know, shocking.

Hubble has observed the death of stars more than 13 billion lightyears distant. How many directions has it observed these stars in? Is it in every direction? Is the light redshifted in every direction? If it is does that mean every non-local point is expanding away from every other point? Or is it just expanding away from our point? If the universe is expanding from every non-local point does this change how we view relativity?

More is different.

  1. And then I found my answer. Hubble constant.

    I loves the interwebs.
