The Big Bang Theory
Scientists think that the universe was created by the big bang, and that energy came out of energy pockets and turned into mass ( E=MC2 ). The universe then started expanding, and heavier elements in the periodic table started to form (at first there was only Helium and Hydrogen).
Scientists believe that the world was created through a process called the Big Bang, which occurred approximately 13.8 billion years ago. This theory suggests that the universe came into existence from a hot, dense state and has been expanding and evolving ever since.
They estimate the age of the Universe in more than 12 billion years.
