Why does the expansion of space cause redshifts of distant galaxies?

Why does the expansion of space cause redshifts of distant galaxies? The amount of space in between the galaxies is increasing. All galaxies are moving away from us because we are at the center of the universe.

Do galaxies move away from each other at constant speed?

Galaxies are moving at a constant speed, the ones further away are so because they move faster. Galaxies move faster away the further they are from each other, because there is more matter between them that expands.

When viewed from Earth the light from very distant galaxies shows a red shift which statement is supported by this evidence this is evidence that these distant galaxies are?

The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point).

Is the universe really expanding?

The Universe really is expanding, and the reason we see the light from distant objects as so severely redshift is due to the expanding fabric of space, not due to the motion of galaxies through space. In truth, individual galaxies typically move through space at relatively slow speeds: between 0.05\% and 1.0\% the speed of light, no more.

How fast do galaxies move through space?

In truth, individual galaxies typically move through space at relatively slow speeds: between 0.05\% and 1.0\% the speed of light, no more. But you don’t have to look to very great distances — 100 million light-years is totally sufficient — before the effects of the expanding Universe become undeniable.

Why aren’t we expanding at the speed of light?

At the largest distances, galaxies are being pushed away so rapidly by this expanding Universe that no signals we can possibly send will ever reach them, even at the speed of light. But even though the fabric of space is expanding throughout the Universe — everywhere and in all directions — we aren’t. Our atoms remain the same size.

What is the relationship between the universe’s expansion and formation?

On the largest scales, the Universe expands and galaxies recede from each other. But on smaller [+] scales, gravitation overcomes the expansion, leading to the formation of stars, galaxies and clusters of galaxies. On the largest scales of all, the expansion wins.
