What Happened After The BIG Bang?

Nearly thirteen billion years ago the universe formed. But what happened seconds afterwards? Well light formed around half a billion years later. Twelve million years ago, the first stars formed. Li and Fe were made. Nearly eight billion years later, the Solar System formed. Fusion of heavy elements were in supernovas for billions of years. Two billion years after, water forms. Then another billion years, and life on Earth has finally happened.

Life on Alpha Centauri?


Alpha Centauri does not feature any liquid. This means there is no water located on Alpha Centauri. However, it does have a magnetic field. It is created by the convection located throughout the body. Because it is a star, oxygen can't be found in Alpha Centauri. No human could survive in it's body without a space suit. In my opinion, I believe Alpha Centauri has no alien life on it. It seems impossible for a star to have a complex life species.

There is a body that scientists believe may have life. It is called Enceladus. It is one of Saturn's largest moons. There is water and nitrogen located out it. There is some simple building blocks which may give a hint that it has life. I think it might have life. There is a small chance that it does, and there is some evidence, but no confirmation of life has been declared. http://www.csa.com/discoveryguides/enceladus/images/enceladus.jpg

Can humans get to Alpha Centauri?

There are different types of measurements to measure big bodies like Alpha Centauri. These include, Kilometers (km), Astronomical Unit (AU), and Light Years (ly). We can measure the diameter of a planet or the distance of 2 cities with kilometers. AU is used when you need to measure the distance of a planet to the sun. 1 AU equals up to 150,000 Kilometers. We use light years to measure distance from planet to a star.

Alpha Centauri c is 168,000 years away from Earth. We could not get there from Earth. It would take too many years to travel. Humans would die before they would land. Unless space travel advances, no live human could get to Alpha Centauri A, B, or/and C.
