What is the relationship between the expanding universe and the distances between stars and galaxies?

This is mostly theory,
Galaxies are made of billions of stars.
For some reason Galaxy's hold on to their stars.
We do not really understand how galaxy's can yet hold their form like this.
Our math so far has trouble with making sense of this.
When comparing one galaxy to another,
size becomes so large words are hard to describe the distance of space.
There is an an incredible amount of space between everything out there.
What is the distance between galaxies, why is it there,
The expanding universe is trying to explain the growing spaces between galaxies yet the galaxies appear to stay bound to themselves.

Does the galaxies expanding?
Yes, the whole universe is expanding rapidly and so are the galaxies within it.
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.
Who showed that other galaxies exsisted and obsereved that the universe is expanding?
Edwin Hubble was responsible for the concept of the universe expanding.
Will astronomers measure all the distances of the 100 billion galaxies in the universe?
It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
If universe is expanding but mass of sun and planets is not then shouldn't gravity be reduced due to space-time and mass relation?
The answer is that the expansion of the universe is only noticeable over distances of hundreds of millions of light years or more. Over the much smaller distances found within galaxies and planetary systems its effects are negligible.
Why are all distant galaxies redshift?
because the universe is expanding.
Will astronomers measure all the distances of 100 billion galaxies in the observable universe?
Someday astronomers may have measured all the distances of 100 billion galaxies in the observable universe.
Are all galaxies moving away from ours because your galaxy is at the center of the universe?
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
Are most galaxies spread uniformly throughout the universe?
Yes, The Big Bang theory says all galaxies are moving outward and the universe is also expanding due to the explosion.
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
