What is Big Bang explosion?
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
What the Big Bang looked like?
In this early stage, the universe was extremely bright and at frequencies of light that humans cannot see. There were no stars, only a uniform and formless soup of particles.
How do we know the Big Bang happened?
That moment was the Big Bang. We can even work out when it happened from the speed of the galaxies: about 14 billion years ago. We can’t actually see the galaxies moving, but the clue is in the light coming from them – it is redder than it should be. We can see that almost all galaxies appear to be moving away from us.
