BIG BANG (Activitiy)

BIG BANG


The astronomers believe that the universe was formed about 14 billion years ago,

at that moment it was inside a very dense bubble.Then it suddenly exploded. The Universe that we know was born.

The land was growing for a few years.



The cosmos contained a vast array of fundamental particles such as neutrons, electrons

and protons.Only 5 percent of the universe is made up of matter such as planets, stars,

and galaxies. Over the next three minutes, the temperature dropped below 1 billion degrees

Celsius. 


After 300 000 years, the Universe had cooled to about 3000 degrees. Atomic nuclei

could finally capture electrons to form atoms. The Universe is filled with clouds of hydrogen

and helium gas.
