The Big Bang

By: Tia Browne, Azine Spalding, Adrian Briseno, Michael Annecharico
Scientists believe the universe was created 13.7 billion years ago.
The Big Bang Theory states that the universe was created in a very hot expansion.
Galaxies are moving away from us
Farthest galaxies move fastest, and away from the explosion.
Explosion left microwave radiation as heat from the explosion.
NASA has launched two missions to study the cosmic background radiation, taking "baby pictures" of the Universe only 400,000 years after it was born.
Electrons bonded with nuclei and made the universe transparent. Gas clumped together to form stars and galaxies.
Our solar system formed 9 billion years after the Big Bang. Our solar system is 4.6 billion years old!!!!
Dark Energy , Dark Matter
What is Dark Energy ?
It turns out that roughly 68% of the Universe is Dark Energy
Neutrons, electrons, protons, positrons, photons, and neutrinos spread across the universe.
As the universe cooled, compounds formed.
One explanation for the Dark Energy is that it is a property of space.
What is Dark Matter?
It dark and not very viewable.
Dark matter is not antimatter because it can produce gamma rays.
