If you have equipment sensitive enough to make the observations and measurements,
you discover that regardless of what direction you look, all of the distant galaxies
outside of our "local group" are moving away from us, and the farther away from us
a galaxy already is, the faster it's moving away from us.
When the local TV station sends a reporter who doesn't understand these things,
to talk to you and get a story that runs 30 seconds and tells it to a lot of other
people who also don't understanbd it, a simple way to describe these observations
is to say that it looks as if the entire universe is expanding and we're at the center
of it. The truth is a lot more incredible and beautiful than that, but in order to have
any hope of understanding or appreciating it, you need more Math and Physics than
the typical TV viewer has, and it helps a lot if you live in a society where staying in
school, studying Math and Science, doing your homework, and graduating, are cool.

What is a universe that expands and comes back together repeatedly?
a closed universe.
A universe that expands and comes back together repeatedly?

If the universe expands would the earths gravity decrease?
no
What model of the origin of the universe believes that the universe expands and contracts in a regular pattern?
it is the oscillating model
How many miles does the universe expand per second?
The universe expands 45 miles every second.
What does the universe continue to do because of the initial big bang explosion?
expands
Dark energy seems to be accelerating the expansion of the universe causing what?
That means that the Universe expands faster and faster. It causes the Universe to grow, and the general density of matter in the Universe to decrease over time.
How far is it to the end of the universe?
Yes universe is endless and it is expanding but every thing that expands has its end once it reaches that end it explodes this might be the cause of the end of universe so there might be a end of universe
What happens to two particles which start off near each other as the bubble expands?
the two particles move further apart as the universe expands because I am a beaver
What is the different between space and universe?
Space contains multiple Universe which shrinks and expands. Means that Space has multiple BigBang and Universes. (This point of view is based on Scientist's theory on Universe). (Subramanian, J.R.)
What is happening to the distance between galaxies because of the big bang?
The distance is getting larger as the universe expands.
How does density change as the universe expands?
The density of what? Any metal, liquid, etc. will have the same density since density depends on mass and volume of the sample (not volume of the universe).
