the Big Bang Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
How elements are formed in the universe?
Elements and the 'Big Bang' theory As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies. The other 86 elements found in nature were created in nuclear reactions in these stars and in huge stellar explosions known as supernovae.
