The Big Bang marks the starting gun of the greatest race of all time i.e. between gravity and the expansion rate. It began some 13.8 billion years ago from a hot, dense, rapidly expanding state. As it is indeed true that our universe is expanding despite gravity. This shows that a more powerful force must be acting on the universe besides gravity.

Astrophysicists have named it as the Dark energy. Dark energy is invisible, but it is based on how fast everything is expanding. Scientists believe that it exists everywhere in space and could make up almost 70% of the universe. According to astronomers, the Sun’s luminosity increases by about 6% every billion years.

THREE WAYS THE UNIVERSE MIGHT END

1. THE BIG CRUNCH

If Astrophysicists theory about dark energy proved to be wrong then gravity would eventually become the most powerful…
