Big Bang Theory
[No Not The TV Show!]
In the 1920s, A Belgian priest named Georges Lemaître was the first to suggest the Big Bang theory when he theorized that the universe began from an early atom. The Big Band theory explains how the universe was created. It has been identified as an unquestionable fact of Creationism. About 15 billion years ago, a tremendous explosion, which is known as the Big Bang, started the expansion of the universe. The theory states that, immediately after the Big Bang, the universe quickly expanded.
[And Not The Candy]
Our solar system is located within a spiral galaxy called the Milky Way galaxy. The Milky Way got its name because most people believed it looked spilled milk.
Our sun and the stars in the night sky are part of the Milky Way Galaxy. The Milky Way Galaxy is 100,000 light-years and about 12-14 billion years old. The rotation of the Milky Way Galaxy is clockwise and the spiral arms trail in the same direction.
Dark matter
Dark matter is anything in the universe that we know it exists but invisible. This means the matter is not giving off light. Black holes could be dark matter. Dark matter exists in our solar system, and a large cloud of it envelops the entire Milky Way. More than 90% of the universe may be dark matter.
Dark energy
Repulsive force that opposes the self-attraction of matter and causes the expansion of the universe to accelerate is dark energy. The concept of dark energy was first proposed, and then discarded, by Albert Einstein early in the 20th century. Roughly 70% of the universe is dark energy. Dark energy is considered a complete mystery.
Ultimate fate of the universe
The Big Game Over?
What is the ultimate fate of our universe? Fire? A Big Crunch? A Big Rip? Big Bounce? Ice?
Most of these theories are based on the Big Bang Theory.
Some say that the universe will not end but earth will.
