What if there were no stars in the universe?

Have you ever wondered, how it will be like in the universe, if there were no stars?

If there were no stars, then there would have been no planets also . Because most of the planets are made of higher elements which results from fusion reaction.

Universe would be dark and cold place. All the light and heat is created due to the stars.

There would have been no Black hole, no Supernova, no hyper nova. The scene would be same as it was before the big bang.

Your body is made up of carbon, oxygen, silicon, calcium, iron and many other elements, but from where did these elements come from?

Definitely not from the big bang, because if you look back in time using the telescopes, you will notice that these elements were found in a very small amount. So some mechanism must be able to produce them.

So, the only mechanism we know of which does this is nuclear fusion, but nuclear fusion naturally takes place in regions which are highly dense, and such regions are seen at the core of a star, which prevents a star from collapsing on itself due to gravity.

So, stars are like the furnaces which forge elements. Without them, there won't be elements other than hydrogen and helium, and hence the universe would be very cold and dark place, bathing itself with cosmic background radiation with no life forms to be seen anywhere.

It's good that there are stars, because of it life exist in the universe.
