The Big Bang never happened and our universe may have no beginning and no end, suggests a new theory by physicists, including one of Indian-origin.
The theory applies quantum correction terms to complement Einstein's theory of general relativity and may also account for dark matter and dark energy.
The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.
Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after - not at or before - the singularity, 'Phys.org' reported.
Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, in Egypt and coauthor Saurya Das at the University of Lethbridge in Canada, have shown that the Big Bang singularity can be resolved by their new model in which the universe has no beginning and no end.
Their work, published in the journal Physics Letters B, is based on ideas by theoretical physicist David Bohm in the 1950s, who explored replacing classical geodesics (the shortest path between two points on a curved surface) with quantum trajectories.
Researchers applied these Bohmian trajectories to an equation developed in the 1950s by physicist Amal Kumar Raychaudhuri at Presidency University in Kolkata.
In addition to not predicting a Big Bang singularity, the new model does not predict a "big crunch" singularity either.
The model avoids singularities because of a key difference between classical geodesics and Bohmian trajectories, researchers said.
Researchers explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term.
These terms keep the universe at a finite size, and therefore give it an infinite age.
Why was that clause necessary?
Kuz INDIANS have had GREAT math minds in the past 150 years or so...?
Yes!
Maybe we need to rethink the concept of happened, is happening, and will happen.

Also Revelation and a couple other places. If it is literal, it sounds like some grand collapse. They had to have gotten the idea from somewhere.
Also there will be new heavens and a new earth. I can't imagine the first one, let alone a new one. And I think this earth is quite beautiful but a dangerous place.
And I'm not convinced there is anything but possibly elemental life anywhere out there. A big question is what is the point of it all for existing. I can see why everything hangs in a delicate balance in our galaxy; the other galaxies may be necessary and I shouldn't think egocentrically as we are as nothing compared to all that.
When I saw a child I used to think that one day science and religion would merge or come to the same truth, but that was probably very naive. The best point made is that so long as we inhabit the earth, we can't see all of what is possibly out there.
However it cam into existence, there was a beginning.
That beginning started with something that was “created”.
Whatever created that beginning stuff, can also destroy that same stuff.
Thus, matter is not eternal, and neither is energy, which are the same thing in different forms.
If matter can come into existence (which it apparently did in the “beginning”), then it can also go out of existence. Creation has an equal and opposite reaction.
There was no big bang. Matter just came into existence (via some creation process), and more of it continued to be created, and was spread throughout the “expanse”. The expanse came first. Neither matter/energy nor the expanse, defined “the beginning”. For there to be a beginning, time had to come into existence too. So, in the beginning, there was just “one” of the stuff that makes up the entire universe. That single bit of stuff, or the “singularity” (if you will), was moved here and there and everywhere, in the expanse, but, to one position at a time for eternity. And back; and forth, ad-infinitum. IOW, what we see here today, particle-wise, can be seen in the past and in the future, and multiple times in the present and multiple times in the past and multiple times in the future.
It just takes one most-minute particle (aka: the creation particle), to compose the entire universe. The universe is just one singularity existing at all times (past, present, and future), replicated “infinite” number of times, to compose that entire universe. Thus, there is no beginning and there is no end. What is, has always been, and will be for time everlasting.
The universe is not just what we see. It is composed of matter and energy and the expanse and TIME. The universe knows no bounds as defined by time. What the universe is, is one single timeless “thing” where time (past, present, and future) doesn’t really exist. Time exists as a measurement defined by humans, so we could more readily try to understand our “observations” and to better be able to handle our everyday lives. We are part of that “intelligent” creation, and we were granted the means to try to understand the tiny part of the universe that our puny brains were designed to handle.
Understanding how the universe was actually created, with all that it entails, is only possible to the power that did the creation. That kind of intelligence has to be millions of times greater than our measly intelligence level.
My Dad tried to explain all this creation business to me as a kid and he admitted “It makes my head spin,” so that was good enough for me. I didn’t try to expand my thinking in trying to resolve the conundrum myself.
“It’s an old theory called, Steady State
that one runs into Olber’s Paradox, aka “the problem of the dark night sky”.
An infinitely old universe will have a night sky filled with light.
We will never know as much as we don’t know, period.

I was waiting for him to weigh in. I guess it’s now ‘settled science’. LOL.
“Why was that clause necessary?”
I was going to say so that people don’t take it too seriously, but I see that it is an Indian outfit publishing this, so I guess they like to point those things out.
“...including one of Indian-origin.”
Why was that clause necessary?
...
Not sure, but as I fancy some nice, spicy southern Indian food, had I just eaten such, I might have thrown that extraneous wording in there, too!
Seriously, though, even if big bang did happen, saying it just happened out of nothing takes way more faith than I have.
Fine....but who created God ?
Actually there have been a number of noteworthy scientists from India. The Nobel Prize in Physics in 1930 went to someone from India, Sir Chandrasekhara V. Raman.
Too early for it to be awarded from hatred of George W. Bush, and I don't think the Nobel Prizes in Physics have been politicized...yet.
Fiat Lux
But if there was no one to hear it, was it really a bang?
How can the universe have “no beginning and end” in view of the second law of thermodynamics?
The Big Bang Theory is taped before a live audience. They insist no laugh tracks are used. This makes me wonder if the audience is composed of gibbons wired to shock collars that prod them to laughter. A guy will walk into the room wordlessly and the audience will laugh. Virtually every sentence draws laughter. In order to believe an audience of grown-ups is that insipid, I defer to the gibbons explanation.
And I have a theory the in certain aspects of reality unicorns are real. It has more validity than this junk.
