Big Bang – overview

Why do scientists think the Universe began with the Big Bang?

According to the Big Bang Theory, the Universe began as a tiny, tiny dot and grew over billions of years to the enormous (mostly empty) space that’s here today.

The thing is though, the Universe began long before humans were around to see. And we can’t make it happen again. Why then do scientists think the Big Bang theory is probably right?

Science is all about observations. We can’t observe the Big Bang happening but luckily, there are useful observations to be made by looking at what is here today.



At this point – please make a choice.
