Scientists have argued about this for centuries. At the moment, most people agree that the Universe began between 12 and 15 billion years ago. It all started with a mind-boggling explosion called the Big Bang.
Amazing! The Big Bang was super-hot! Scientists don’t even bother writing out all the zeros in its temperature. They write 1027 C meaning 10 with 27 zeros after it!
What was the Big Bang?
It was a huge explosion that created all the mass and energy in our Universe in less than a second! The effects of the blast are so strong that the Universe is still expanding.
What if the Big Bang happened again?
It couldn’t happen again in our Universe, but some people think it may be happening millions of times, making millions of different universes. Only a few would last as long as ours — most would pop like soap bubbles.
Is it true? You could see the Big Bang through a telescope.
Nearly. Our telescopes aren’t powerful enough yet – but we can already see light from the other side of the Universe that began its journey just after the Big Bang!
