We all know how the black holes form from stars. We also know that there is a region outside the black hole called "event horizon". Beyond such a region, our laws of physics become invalid. (Right?)
We also believe that the universe began with a huge explosion known as the Big Bang.
Now here comes the interesting bit I was wondering. There is a length called "Planck length". I know (from calculation or data) that the Schwarzschild Radius is bigger than the Planck length. Our knowledge about the origin of the universe becomes meaningless if we go back in time and the size of the universe becomes less than the Planck length. So, when we either go into the black hole's singularity, or come out from the singularity of the origin of the universe, our laws of physics is not valid.
So I want someone to tell me what the purpose of the GUT (Grand Unified Theory) is. Or does the Quantum theory allow us to work out the origin or end of the universe?
