isotropy (things look the same in all directions) No matter where you traveled in space, you would observe very similar distributions of galaxies.
Hubble's law describes this expansion.. Please help!
I'm thinking b? The theory used to determine these very great distances in the universe is based on the discovery by Edwin Hubble that the universe is expanding. That the spiral arms are regions of star formation.
But am so unsure and can't miss the question again. Hubble showed that, in our expanding universe, every galaxy is rushing away from us with a speed which is in direct proportion to its distance, known as Hubble’s Law, so that a galaxy that is twice as far away as another is receding twice as fast, one ten times as far away if receding ten times as fast, etc. a) The solar system is expanding.

Scientists must move from direct observation to using observations in conjunction with a theory. If we assume that the expansion's apparent velocity (that is, how fast the galaxies appear to be moving apart) has been constant over the history of the universe, we can calculate how long ago the galaxies began their separation.
A major discovery made by Shapley using RR Lyrae stars and globular clusters established That the spiral nebulae are actually galaxies outside the milky way. Expanding Universe The distant galaxies we see in all directions are moving away from the Earth, as evidenced by their red shifts. This is an example of.
