The Big Bang Theory Unit

The universe is expanding.  This means that:

• Galaxies are getting bigger.

• Atoms are getting bigger.

• The universe is creating more matter.

• The amount of space between galaxies is increasing.

Match the following

• The Big Crunch

• The universe will expand until gravitational forces break down and stars and planets are ripped apart.

• The Big Rip

• The universe will expand and then reverse, resulting in another big bang.

• Dark Matter

• The thing that is slowing the expansion of the universe enough to prevent galaxies from flying apart.

• The Big Chill or The Big Freeze

• The universe will keep expanding until everything freezes and life is no longer sustainable.

• Dark Energy

• Something that we cannot observe but we know exists because it is speeding up the expansion of the universe.
