Birth of the universe

                 BIRTH Of UNIVERSE 


Scientist define the Universe as absolutely everything that physically exists. But the Universe has not always existed. It is believed that the Universe was created by the Big Bang, when it started to grow from a tiny point that contain all matter and energy.

> WHAT WAS THE UNIVERSE LIKE AT THE BEGINNING?
The early universe was very small, but it contained all the matter and energy in the universe today. It was a dense and chaotic soup of tiny particles and forces. But this original universe lasted only a split second just three trillionth of a second.

> WHAT WAS THERE BEFORE THE UNIVERSE?
No one knows. Some people think there was an unimaginable ocean, beyond space and time, of potential universe continually bursting into life or failing. Our succeeded.

> CAN WE SEE THE BIG BANG?
Astronomers can see the galaxies still hurtling away from the Big Bang in all directions. They can also see the afterglow low level microwave radiation coming at us from all over the sky, called background radiation

> HOW DO WE KNOW WHAT THE EARLY UNIVERSE WAS LIKE?
Machine called colliders and particles accelerators can recreated condition in the early universe by using magnets to accelerates particles to astonishing speeds and then crashing them together.

>HOW HOT WAS THE BIG BANG?
As tje universe grew from smaller than an atom to the size of a football, it cooled from infinity to ten billon billon billon°C

>WHAT WAS THE BIG BANG?
In the beginning, all the universe was squeezed into an unimaginably small hot, dense ball. The big bang was when this suddenly began to
swell explosively, allowing first energy and matter, then atoms, gas clouds and galaxies to from. The universe has been swelling ever since .
