Everybody has a basic idea of what goes on with
Cosmologists generally accept the Big Bang theory as the official start to the universe. A couple of physicists have developed a new model that could blow this old theory out of the water. It could also explain the existence of dark matter and energy. How so?
The Big Bang theory, which holds that all matter in the universe burst from a singular point approximately 13.8 billion years ago, still prevails amongst scientists. The Big Bang aligns nicely with Einstein’s theory of general relativity, but the theory neglects to explain what happened before or during the singularity. The theory also doesn’t explain why the “bang” happened at all.
A new theory seeks to explain all that and more. Two researchers, Saurya Das (University of Lethbridge in Canada) and Ahmed Farag Ali (Benha University in Egypt) suggest the universe has always existed. It never had a beginning, and it shall have no end. They say the bang may still have happened, but the universe is not finite: “It lasted forever. It will also not have an end … In other words, there is no singularity.” Further and as Ali explains, “the Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there.”
Here are their findings in an easily digestible nutshell:
(1) They weren’t trying to disprove the Bang theory, it just happened: Ali and Das say their research set out to unite quantum mechanics and general relativity. While trying to make quantum adjustments to Raychaudhuri’s equation (on formulation of singuliarites), an unexpected result happened. Ali and Das found that the universe was probably never infinitely dense enough to support a singularity before the bang.
(2) Discovery of a new gravity particle? Ali and Das theorize that the universe is filled with quantum fluid. This fluid is made up of gravitons, which have no mass themselves but can transmit gravity and affect quantum phenomena macroscopically. This could explain how the bang happened and also account for what came before the big event.
(3) More work to be done: All of this complicated scientific data could eventually, according to Ali and Das, account for the existence of dark energy and dark matter. For now, Ali and Das have opened up a valid challenge to a long-held theory that could certainly use some readjustment. And you never know, the new theory could create some incongruities of its own.
