The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
Why does the red shift of galaxies provide evidence that the universe is expanding?
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.
How fast are galaxies moving away from each other in the expanding universe?
Galaxies in the expanding universe are moving away from each other at speeds proportional to their distance, with more distant galaxies moving faster. This phenomenon is known as the expansion of the universe.
Who showed that other galaxies exsisted and obsereved that the universe is expanding?
Edwin Hubble was responsible for the concept of the universe expanding.
Who showed other galaxies existed and the universe is expanding?
Edwin Hubble
Who showed that galaxies exist and observed the universe is expanding?
Edwin Hubble.
Who showed all galaxies and discovered that the universe is expanding?
Steven hawking
Which of the models predict that galaxies should be getting farther apart now?
The expanding universe model predicts that galaxies should be getting farther apart now. This is based on the observation that the universe is expanding, with galaxies moving away from each other at increasing speeds.
Why scientist don't expect to find galaxies that have large blue shift?
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.

What shows the galaxies expanding?
Yes ...why.. well there is a theory that once the universe was as small as a match's red head? i don't know what it's called what ever...so when that bead explodes and it expands. and scientists believe that it keeps expanding. Another question you should ask your self is if that the universe was that small what was around it? answer it cause i wanna know and hope this helps!
