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.
If this theory was any good I doubt it would require a press release.
God, as Creator, exists outside space and time. Nothing can be said of His origins since nothing can be known about reality prior to existence. In the sense in which we talk about existence God can not be said to exist. His reality both supersedes and precedes existence. As an article of faith I know that God, creator, is also sustainer of the world. He is "in" the world but is not "of" the world. His presence is guaranteed by the presence of His Spirit and of His Son who comes to us that we may be reunited with him in His perfection. I, and all believers, are linked with Him in His eternality.
A singularity divided infinitely would be perceived infinite. Space and Time can be perceived both Singular and Infinite. In other words, the Big Bang did not happen, did happen and is happening - all 'now'...
Exactly...
When does light run out of gas?
Ping
Light is a form of energy (the only kind we can actually see). Energy cannot be destroyed, it can only turn into other kinds of energy.
If there is nothing to stop the light from turning into another form of energy then it will simply carry on forever.
However, chances are that somewhere, at some point, in its journey, light will eventually hit “something”. A lot of that light will bounce off the surface it hits, and some of the energy will be converted into other forms of energy, like heat. Eventually it is possible for 100% of the light energy to be converted into other forms of energy.
But, assuming it is not converted into anything else it will just continue along its path forever
ping ResponseAbility , he’s the one questioning this
But... but...
Our whole universe was in a hot dense state
Then nearly fourteen billion years ago expansion started. Wait...
The Earth began to cool
The autotrophs began to drool
Neanderthals developed tools
We built a wall (we built the pyramids)
Math, science, history, unraveling the mysteries
That all started with the big bang!
I meant it for you re running out of gas. But what the heck? Pinging RA to #87,
Evolution, Big Bang, Global Warming. Three strikes you are out.
Genesis 1:1 says God created the heavens, which would be the material universe. Nowhere in the Bible does it say that the universe was itself eternal like God.
Again, a universe that always existed is what the atheist science-worshipers originally clung to as “proof” of no god. Edwin Hubble shattered that notion.
My “running out of gas” question was to get him to elaborate on that theme of his
If you want to hear an Indian person go on and on and on about an accomplishment, just mention the Bose Wave Radio in passing.
People get strange ideas. An otherwise intelligent, rational, maintenance technician and friend of mine believed fervently that sound is on the electromagnetic spectrum.
So, no reason for the dark matter kludge. Thanks TBP.
****But, assuming it is not converted into anything else it will just continue along its path forever****
I have a hypothesis that at some point light unravels from its little cocoon and becomes Dark Matter, or at least a small component of it.
I love big bang theory, but I’ll admit that I’m a big nerd.
The concept of the origin of the universe coming from nothing is bizarre and the most renowned physicists agree, though they quibble over the details. The concept of an eternal god seems equally bizarre. Before the universe their was no time which is also beyond logic. Everything that we know has a beginning except the universe. When one can tell me what existed in the instant before the big bang I will tell you if it is physics or god.
I vote for god.
