Africa, The Cradle of Human Civilization The Big Bang Theory is a strong scientific effort to explain how our universe began. Even in our generation, people are still asking that number one question “Where did it all begin and how was the universe created?" According to the Big Bang Theory, around 15 billion years ago a gigantic explosion occurred and this expanded our universe. The energy of space and all of the matter met at one point and it clashed. The person that we give credit to for making this discovery is Edwin Powell Hubble. He was an American astronomer. Hubble played a major part in establishing what we call modern day astronomy. In 1919 Edwin Powell Hubble helped to complete the world’s largest telescope. Around the year 1922-1923 Edwin Powell Hubble made an amazing observation. He proved that the nebula was too far away to be part of the Milky Way galaxy. A nebula is a cloud of gas & dust combined. Within the Nebula we learned that there were certain elements necessary for the creation of life and these elements were present during creation. Edwin Powell Hubble also noticed that there were many separate galaxies out there in the universe. When he shared his observations, it changed the scientific view of the universe. As Edwin Hubble continued to conduct his research and observe the stars, he discovered a new phenomenon. In 1929 he observed that the universe was continuing to grow and expand. He also discovered that the galaxy's speed is the same as its distance. Since its birth the Big Bang
Theory has been challenged by many. Those who believe in the theory had to search for more evidence to prove that they're correct while those who oppose the theory continue expressing their views. In June of 1995 NASA made some discoveries which granted themselves as proof that the Big Bang Theory does exist. The astronomers used the Astro-2 observatory to
