The Big Bang Theory The Big Bang theory tells us how the Universe began and is evolving. In essence, it is a theory that was created to explain two facts that we know about the Universe - it is gradually expanding and cooling. In the 1920s, Edwin Hubble found that galaxies far from our own Milky Way are moving away from us. In fact, the further away galaxies are, the faster they are receding. So he concluded that the whole Universe must have been expanding. Working backwards this means that at one stage the Universe must have come from a single point. We also know that the Universe is cooler now than in the past. In the 1960s Arno Panzias and Robert Wilson detected the afterglow of the Big Bang, known as the cosmic microwave background [or CMB for short], which revealed that the Universe was once a very hot, hostile place. Both these discoveries led astronomers to deduce that the Universe began as an infinitely compact fireball. The Big Bang describes how this fireball grew to form all the stars and planets we see around us now. Because of its name many people think of the Big Bang as a kind of explosion that happened at some specific point in space, but this isn't correct, as the Universe didn't spring from one central ignition point. Instead, during the Big Bang space was first created and then stretched. How does this scientific theory Challenge the Christian account of creation? Atheists argue that this theory is the best we have to explain the origins of the universe. This theory states that the universe ‘just happened’ and that it did not emerge as a result of the activity of a creator God. Therefore, the universe is random and not designed! In Christianity, the creation accounts are found in the first two chapters of the book of Genesis in the Bible. According to the book of Genesis, the universe was created in six days and God rested on the seventh. The first Human beings to be formed were Adam and Eve and all humans are descended from them. The Big Bang theory challenges this biblical account of creation because scientists argue that the universe was created from a singular point over 13 billion years ago and that the process of creation did not take place over a six day period. Genesis 2:1-4 ‘And so the whole universe was completed. By the seventh day God finished what he had been doing and stopped working. He blessed the seventh day and set it apart as a special day, because by that day he had completed his creation and stopped working. And that is how the universe was created.’
