Two physicists have proposed a new theory regarding gravity that necessarily leads to the conclusion that the universe had no beginning (i.e., no big bang) and no ending.
'The math and the Big Bang theory itself break down because of the infinities,' Professor Saurya Das at University of Lethbridge, Canada told Dailymail.com.
'In other words, the theory predicts its own demise. It also does not explain where that initial state, came from.'
To help solve this problem, the scientists combined general relativity, which describes the forces around us, with quantum mechanics, which governs small objects.
They began with equations created by physicist David Bohm, who in the 1950s attempted to use quantum theory in place of classical equation to describe the shortest path between two points on a curved surface.
They then combined this with an equation by Professor Amal Kumar Raychaudhuri at Presidency University, in Kolkata, which described a fluid of small particles that pervades space.
This fluid is the quantum version of gravity, which has dubbed a graviton by Professor Das and co-author Ahmed Farag Ali at Benha University.
They showed that unlike classical trajectories - which are paths of particles going into the future or past – the quantum particles can never meet or cross.
'As far as we can see, since different points in the universe never actually converged in the past, it did not have a beginning,' said Professor Das.
'It lasted forever. It will also not have an end…In other words, there is no singularity.'
But if there was no Big Bang, what is the history of our universe?
'The universe could have lasted forever,' speculates Professor Das.
'It could have gone through cycles of being small and big.
'Or it could have been created much earlier.'
The theory may also potentially explain the origin of dark matter and dark energy.Obviously the article is lacking sufficient details to form any conclusion, but it is nice to see someone thinking outside the box of string theory.
