Origins Of The Universe
The Big Bang Theory.
About 15 billion years ago there was an explosion between two particles that created an explosion because all the heat in the universe was released and started to expand and is still expanding. Scientists believe that the Universe was initially so hot
and dense, that even basic particles like protons and neutrons could not
be found. Instead, different types of matter called matter and anti-matter collided together, creating energy. But as the Universe began to cool
during the first few moments, protons and neutrons began to form. Then slowly
over time these protons, neutrons and electrons came together to form basic elements such as Hydrogen
and Helium. During the billions of years that followed, stars,
planets and galaxies formed to create the Universe, The universe is always expanding and will keep growing untill all the heat is finally cooled.
