stage 2

the force of gravity makes them come spiralling in, this gains a lot of heat energy...

stage 3

when temperature gets high enough hydrogen nuclei undergo nuclear fusion - gives out lots of heat light

stage 4

a star is now born. it is now in a huge stable period ...

4 of 5

what is this stable period?

it is when there is LOADS of hyrogen

and the radiation pushing outwards and the gravitational pull pulling inwards is at equilibrium

this can last for a veryyy long time
