How did Hubble' s discovery that the universe is currently expanding change scientific thought about the size of the universe in the past?

Expansion, run in reverse, is contraction. The universe gets larger as it moves into the future, and smaller as we examine its past. If we go back to the time when the expansion originally began, which was the Big Bang, the universe was very small, perhaps only the size of a proton, or even a singularity of zero volume.

The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
What is important about Hubble discovery that there is a red shift in the spectra of galaxies?
that the universe is expanding(: YouR WelomE
Which view of the fate of the universe is currently favored a big crunch or an endless ever expanding universe?
Answer: I don't believe that any consensus has been reached, although it seems that more people are arguing that a "big crunch" is more likely that an endless expansion into increasing entropy. But this is definitely a question that you should ask again in about 15 years. Answer number 2: The ever-expanding Universe. The main reason this seems likely is that it has been observed that the expansion of the Universe is actually accelerating - i.e., it is expanding faster now than in the past. Answer number 3 : I agree with answer 2. The discovery of "dark energy" and the increasing rate of expansion of space favors the ever expanding Universe.
What has the Hubble telescope contributed to our knowledge of astronomy?
== it gave the idea that the universe is expanding, which has a lot of supporting data currently. The galaxies in the universe appear to be moving away from each other.==

If all galaxies began to show blue shifts what would this change indicate about the fate of the univerese?
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
Is the universe infinate?
Scientists currently believe that no, the universe is not infinite. It is of a finite size however, this finite size is constantly expanding but not expanding AWAY from anything, just expanding

The discovery that the universe appears to be expanding led to a widely accepted theory called?
Edwin Hubble was one of the scientists who realized that the red-shifted light from far-away galaxies indicated that the universe is expanding.

What is a scientific contribution?
Presenting a discovery (new knowledge) that adds to our collective understanding of the universe and how it works.
American astronomer Edwin Hubble later interpreted this discovery as evidence that?
Galaxies are moving away from each other in a constantly expanding universe.
What info has Hubble contributed astronomy?
He gave the idea that the universe is expanding, which has a lot of supporting data currently. The galaxies in the universe appear to be moving away from each other.
Why is the universe cooler?
It is because the Universe is expanding.
