People have long debated the origin of the universe. Some rely on the big bang theory, while others believe everything happened by chance, and still others believe a supernatural being created everything in the universe. These ideas have long been debated by several great minds including Copernicus, Kepler, Galileo, Lemgitre, Hubble, and Hawking. It has only been in the past 40 years that technology has allowed us to travel beyond our Earth's atmosphere to investigate and assess the validity of the theories on the origin of the universe. Throughout recorded history, there have been many varying cosmological theories.
Every culture has a different myth or legend of how the universe was created.
Some of the most widely known or accepted hypothesis came through religion. These include the Hindu belief in the four-headed god Brahma who created the universe as well as all of humanity. Hindus believe that when Brahma sleeps the universe and everything in it is destroyed, and when he awakes the entire universe is created new, creating a perpetual cycle of creation and destruction. The ancient Chinese believe in two opposite forces known as the yin and yang. Yin is the power of darkness while yang is the power of light and sunshine.
