Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.

If there was no universe or plants where did the big bang happen?
It happened in the center of the universe, for which it is still expanding on the universe.
What are the universal things?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
Will the universe ever begin to contract?
It doesn't seem so. There is evidence that the expansion is accelerating (the Universe is expanding faster than in the past). The reason for this is still somewhat of a mystery; do an Internet search on "dark energy" for more details.
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.
Is the universe still expanding?
Yes, and the expansion is accelerating - it is expanding faster and faster.
Do you believe that the universe is still expanding?
The evidence - for example, from the redshift, normally attributed to a Doppler effect - is that indeed, the Universe is expanding.
If there was no universe or plants where did the big bang happen?
It happened in the center of the universe, for which it is still expanding on the universe.
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 things are beyond the universe?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?

How did the size of the universe change?
In the immediate aftermath of the "Big Bang" there was rapid inflation of the universe. That slowed and the universe is now believed to be still, slowly, expanding.
Which term is evidence that the galaxy is still expanding?
There is no evidence that our GALAXY is expanding. Are you confusing the word galaxy with the word universe - if so they are NOT the same thing.
Why is the universe cooler?
It is because the Universe is expanding.
Is universe getting bigger?
Yes. To be more exact, it is "space" within the "observed universe" that is expanding. A confusing fact is that many astronomers believe the universe as a whole may already be infinite in size. This doesn't stop them saying the observable universe is still expanding. "Infinity" is a tricky idea.
How much did the universe increase after the big bang?
From an infinitesimally small point to the present size, the universe is still expanding as a result of the big bang.
When was ...And the Ever Expanding Universe created?
...And the Ever Expanding Universe was created on 2009-07-14.
