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.
I heard it and my ears are still ringing.
Can this model be applied to the Clintons?
Prachett had Alzheimers. He likely wanted a legal way out before he was totally incapacitated.
A band of neolithic desert dwellers?
Hmmmm. These places are not hotbeds of physics. Not that they have to be, but I'll reserve judgement.
Why was that clause necessary?
What have you got against Indian Physicists? Huh?
personally I lean toward the swiss cheese theory ...
What do we know about God (one’s particular theology aside)? The defining characteristics of God would be eternality and infinity. (i.e. God would be infinite and eternal.)
So a Universe that has always existed (and has no boundary) points directly to God.
To say that the Big Bang never occurred is not to say that the Universe hasn’t changed and evolved over time.
At the still point of the turning world. Neither flesh nor fleshless;
Neither from nor towards; at the still point, there the dance is,
But neither arrest nor movement. And do not call it fixity,
Where past and future are gathered. Neither movement from nor towards,
Neither ascent nor decline. Except for the point, the still point,
There would be no dance, and there is only the dance. (T.S. Eliot)
The static state theory holds well with the observable universe. What one needs to reflect on is the introduction of time. Time seems to be the variants that throws everything out of kilter. Assume a universe that has always existed and will always do so. Without time then this is logical mathematically and metaphisicallly. Without time, the universe was never created since the idea of creating something denotes a time component to it. A beginning and end. Without time there is no entropy. Creation out of nothing supposes a timeline: there is a start to something, time? Then again, time is a human construct.
Haha, live studio audience my ass.
The only way they have a live studio audience is if the audience is prompted to laugh every single time someone says anything.
Horrible show, never understand why people like it, it’s always been utter garbage.
They have a live audience. You can get tickets.
But if what we hear during the show is un-augmented laughter, the audience is a bunch of mental cripples.
Did he create it for the other religions? Kind of poses a problem doesn’t it?
Did you read my post and the scripture mentioned? It is self-explanatory.
That was probably my favorite Big Bang Theory scene. Because of the, uh, humor.
****An infinitely old universe will have a night sky filled with light****
I have yet to see proof that light travels forever.
I wonder if that's like a Bohmian Rhapsody?
All seriousness aside, though, the bit about "finite size and infinite age" makes no sense if the U is expanding. Can't have all 3.
As it travels, it loses energy which is expressed by a lower frequency. At some point, the frequency is so low you can’t see it. I suppose then you could say is stopped. But as we can see, the surface of a star puts out a LOT of light and we can see it from incredibly far away, almost back to the ‘flash’ when light became able to ‘shine.’
Ya think?
I’m sure the atheists will have a new cockamamie story before long!
