Big Bang

According to our current estimates of the matter in the universe, what will happen to the size of the universe as it ages?

• The universe will continue to get bigger and bigger and bigger forever.

• The universe will eventually stop expanding and shrink back down ("The Big Crunch").

• The universe will eventually stop expanding and its size will stabilize

• The universe will only continue to grow if it's a good universe and eats its vegetables

The universe is expanding!  This means that:

• all of the galaxies are spreading out.

• the universe must have started from a single point.

• the universe is cooling down.

• all of the above.

Which statement is true about the Big Bang Theory? Choose all that apply.

• It should appear longer because of a redshift.

• the universe formed by the rapid expansion of space from a point 10–20 billion years ago

• The universe is expanding because light from faraway stars and galaxies is shifting towards the blue colors.

  
  

• When stars and galaxies move farther away from each other, we say that the universe is expanding and that this is due to a shift in the frequency of light coming from these light sources.
