It's a long story. A very long story. For as long as man has existed, they didn't know the truth that lay above their heads. But now, everything changed. We discovered what the sun provided us, and what could possibly happen to us. Our sun and Earth are both 6 billion years old. More than half of the Earth's life is gone. 5 billion years from now, our sun will become what is known as a Red Giant. The sun is fueled with Hydrogen, the element with the lightest atomic mass on the Periodic Table of Elements. Once the sun can no longer rely on Hydorgen, it will fuel itself with the element with the element that has the secong lightest atomiv mass, which is known as Helium. After our sun becomes a Red Giant, it will become what is known as a Supernova explosion. It will aproximately take around 1 million years for the Supernova to become a Neutron Star. And our story is not finished here. The Neutron star can become a black hole, or recycle itself to become a new star. Black holes are known to devour stars, and other unimaginable things. According to the study of Mars, they have found some possible bacteria-like lifeforms, living on the surface. This could prove that we are not alone. Is the Universe real, or is it just an illusion? We, the people of this super tiny planet will never know the truth, unless we do more research. New things are being discovered each day.
