The galaxies themselves are not expanding, and they're not all retreating out
from any central point. Every point in our Universe is moving away from every
other point, because the entire fabric of space itself is expanding, taking the
matter along with it. Thus, every observer at any point in our Universe observes
all other galaxies moving away from the point where he happens to be located.
No point can claim to be the "central" point.
It was Edwin Hubble, working at Caltech and the Mt. Palomar observatory, who
was able to compile the radial speeds of enough distant galaxies to demonstrate
the general expansion in every direction.

Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
Why galaxies are going far away and the universe seems to expanding?
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.

What model of universe supported by red shift?
The universe expanding in all directions.
If scientists say the universe is everything and the universe is always expanding then what is the universe expanding into?
It is not exactly expanding into anything. The galaxies are moving apart from each other, from which we can infer that the universe is expanding. Theoretically, this is a result of the Big Bang, in which the universe began when all matter was compacted into a very tiny sum, and then exploded apart in a very big bang, and as a result is still expanding today.
What do galixies have in common?
they all have stars.
How high is the universe?
The Universe keeps on expanding in all the sides so no one can really tell how high is the universe.
Why are all distant galaxies redshift?
because the universe is expanding.
Who showed all galaxies and discovered that the universe is expanding?
Steven hawking
Is the sun expanding or contracting?
We believe that the universe is expanding.The universe is currently expanding, as evidenced by the Hubble Constant, which indicates that the greater distance a star is from an observer, the faster that star is receding away from the observer. This Hubble Constant holds true for all observers, no matter where they might rest in the universe, and the Hubble Constant applies to all stars in all directions of the sky for each observer.
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.
Is the center of the universe very close to us?
We have no idea where the centre of the universe it and therefore we can not answer this question. The universe is expanding in all directions and we can not tell one direction from another.
Is there any proof that the universe is changing?
Yes, there is proof. The universal redshift that appears in all distant electromagnetic spectra proves that the universe is expanding.
