The universe

Scientists are always trying to measure the universe. They use special equiment that tells them if an object is moving closer or farther away from Earth. Many scientist belive that the universe is still expanding and might never stop. Scientist also belive the universe started with something called The Big Bang. The Big Bang theory is that before the universe started there was matter and anti-matter. Massive amounts of matter and anti-matter collided and caused a huge explosion. Most anti-matter was destroyed, but some matter survived. This created the universe. Some scientists believe the universe has already expanded and the light from far away galaxies are finally reaching us. The universe is on big mystery on how it started. What do you think happened?
