New quantum theory says universe has 'no end and no beginning'






Until now, scientists have generally agreed that the universe has

celebrated about 13.8 billion birthdays, as calculated using Einstein’s

theory of general relativity. The ‘Big Bang’ theory (no relation to the

popular sitcom) relies on Einstein’s ideas to clearly explain what

happens in the moments and years and eons following the expansion of the

universe

from a point of singularity, but it fails to offer an explanation for

what happened prior to that event. For this reason, quantum theorists

have long been brainstorming other possible explanations that don’t have

such glaring inadequacies.





Ahmed Farag Ali, at Benha University and the Zewail City of Science

and Technology (both in Egypt), and Saurya Das, at the University of

Lethbridge in Alberta, Canada, believe they have the answer to this

quandary, as well as a few others. The two co-authored the paper

outlining their new model, in which the universe has no beginning and no

end. Their new quantum model, which the scientists refer to as ‘quantum correction terms,’ resolves the problem of the Big Bang singularity.



Das participated in a separate study, with Rajat Bhaduri of McMaster

University, Canada, which has takes this model one step further. They

theorize a new gravity particle that was present in the universe at all

epochs. Further analysis of their model will be the future focus, as

they seek to explore the potential to account for dark matter and dark energy.




Essentially, these cosmologists believe their model will take much of

what we think about the origin of our universe and throw it out the

window.
