  • What is the Big Bang?

    The Big Bang is the name that scientists have given to the start of the universe.

    Scientists used to think that the universe had always existed. Many thought that it was infinitely large and old, with no beginning point. This was called the steady state model or theory. But some scientists and mathematicians, including many who believed in God, started to notice clues that suggested that the universe was expanding and cooling and had been for a long time. From this they concluded that the universe had therefore been smaller and hotter in the past.

    Taking this further, some scientists worked out that, at first, all the matter and energy in the universe was squished into a single very tiny, very dense, very hot point, before the universe started to expand very quickly, marking the beginning of both space and time! This idea about the beginning of the universe earned the nickname the ‘Big Bang’ by those who criticised it, and the name stuck!

    One clue that helped with the development of the Big Bang theory was ‘red shift’ data, which showed that galaxies and other matter in the Universe appear to be moving away from us, and from each other – suggesting that the universe is expanding The discovery of the ‘Cosmic Microwave Background Radiation’ also helped support this new idea, as scientists interpreted this radiation as the leftover heat from the Big Bang, and it is not explainable in a steady state model. Over time, lots of other discoveries have added confidence to the idea that the universe had a beginning point about 13.8 billion years ago.

    Since the Big Bang, all the stars, planets and everything else in the universe have gradually been made out of the matter and energy that was there at the start of the universe, in that hot, dense point.
