The Big Bang May Never Have Happened

As crazy as it sounds, we’ve all kind of accepted the part of the Big Bang Theory that says the universe started as a single point around 13.8 billion years ago. The thing is – a lot of theoretical physicists aren’t enthralled with that idea, as a lot of widely-accepted general relativity equations start to break down as you approach the “singularity”.

One recently published study asked the question: What if the there was no Big Bang and the universe has been around since…forever?

“The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,” Ahmed Farag Ali, a physics lecturer at Benha University in Egypt, told

No singularity, no “big crunch”

Published in the journal Physics Letters B, the new study from Ali and his co-author Saurya Das resolved questions around the singularity with an entirely new model based on concepts put forward by the unorthodox theoretical physicist David Bohm in 1950. The study team said they were particularly interested in Bohm’s investigations into quantum trajectories.

In the new study, Ali and Das applied Bohm’s equations to an equation formulated by physicist Amal Kumar Raychaudhuri while working at Presidency University in India. The theoretical model the two physicists came up with does not predict a Big Bang singularity. It also does not predict a “big crunch,” or the theory that gravity will cause the universe to eventually collapses in on itself, returning to a singular point.

The researchers said their model doesn’t predict singularities because of a major difference between classical and quantum trajectories: classical trajectories eventually cross each other and quantum trajectories never do.

Quantum fluid

The study scientists also argued that their quantum modifications can be thought of as a universal constant that disposes of the need for dark energy, on which the current Big Bang Theory is based. The new study terms maintain that the universe has a specific size and, therefore an unlimited age. The calculations also make predictions that agree strongly with current findings and observations of the universe, the researchers said.

The new study also puts forward the idea of a universe filled with a quantum fluid that might be made of gravitons—theoretical massless particles that regulate gravity. If gravitons exist, they are suspected of play a major role in a theory of quantum gravity.

The study authors noted that their model was not applied ad hoc in an attempt to challenge the Big Bang singularity. However, they said they are now motivated by the possibility of resolving the Big Bang singularity and accounting for both dark matter and dark energy. The study team said they plan to apply their model more rigorously in the future and this upcoming work should include reworking their calculations while considering additional factors. They said these additional considerations should not significantly affect their current conclusions.

“It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once,” Das said.
