The Big Bang

When we look at the night sky we can see the stars in our galaxy. But there are also some fuzzy patches so we need a telescope to see them clearly. There are other galaxies like our own - but they are much, much further away than the stars.

If we look closely at these galaxies, we'd expect that some would be moving towards us and some would be moving away, But in fact, almost all galaxies are moving away from us - some at very high speeds indeed.

After the Big Bang, the whole Universe was flooded with incredibly bright light. As the Universe has expanded, that light has been stretched so that it is now microwaves. AND THAT’S HOW WE KNOW THE BIG BANG HAPPENED!!

How we know the big bang happened?

.The big bang was such a huge event that the waves it created are still traveling to this very day

. The universe is 13.7 billion years old

. Space began to expand and pushed matter apart

. In the beginning the universe was so hot all the universal forces (gravitation, electromagnetism, etc.) were one force this is a fact!!
