The universe is constantly expanding at a speed faster than light, which would seemingly make it impossible to see the light of distant galaxies. If this is the case, how do we discover new things everyday in this ever-expanding universe?

Key Points:

  • Doesn’t cosmic expansion Einstein’s Theory of Special Relativity? This theory is referring to things that are moving through space, not space itself.
  • Hubble’s observations of the night sky led us to the discovery of universal expansion. Hubble noticed that the further he peered into space, the faster objects were moving away from him.
  • We can see objects outside of the Hubble Sphere.
