A New Twist To Big Bang: Universe Has No Beginning And Probably No End

Researchers suggested that the universe has no beginning, it may have existed forever and the Big Bang did not mark the birth of the universe.

The age of universe based on the Big Bang theory is approximately 13.8 billion years old and yes, that is which we consider the event that flung the formation of the universe. However, two researches, Saurya Das from the University of Lethbridge in Canada and Ahmed Farag Ali from Egypt’s Benha University, have suggested that the universe has no beginning and it may have existed forever and the Big Bang did not mark the birth of the universe.

The paper, published in Physics Letters B, apparently goes against Einstein, who suggested that the universe exploded outwards from a single, infinitely dense point 13.8 billion years ago.

The claim, which is based on a new model that applies quantum correction terms to complement Einstein’s theory of general relativity, anticipates that the universe originated when an infinitely dense single point, or singularity began to expand in a Big Bang. Some researchers find singularity problematic because it does explain what happened before or at the moment but only explains what happened after the Big Bang.

According to the statement at, researchers said the Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there. However, the model they newly proposed can resolve that. Eliminating singularity, their model predicts that the universe has no beginning and it has always existed in quantum potential before collapsing into the Big bang.

Researchers do not apply their quantum correction terms for one specific case in an attempt to eliminate the Big Bang singularity. Their work is based on David Bohm’s idea of replacing classical geodesics (the shortest path between two points on a curved surface) with quantum trajectories.

Using these Bohmian trajectories to an equation developed in the 1950s by physicist Amal Kumar Raychaudhuri at Presidency University in Kolkata, India, Ali and Das derived quantum-corrected Friedmann equations, which describe the expansion and evolution of universe (including the Big Bang) within the context of general relativity.

Their model also takes account of mysterious dark matter and dark energy and also predicts cosmological constant.

The model also describes the universe as being filled with a quantum fluid which might be composed of gravitons—hypothetical massless particles that mediate the force of gravity. If they exist, gravitons are thought to play a key role in a theory of quantum gravity.

“As far as we can see, since different points in the universe never actually converged in the past, it did not have a beginning. It lasted forever. It will also not have an end. In other words, there is no singularity. The universe could have lasted forever. It could have gone through cycles of being small and big.” said Professor Saurya Das in a statement at Metro.

“It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once,” Das said. [, TechTimes, One Universe at a Time]


  1. Despite Ghez, this theory would not explain why everything is accelerating away from everything else (red shift,) unless dark energy is cited as the cause; but that is rather speculative at the moment. Otherwise, seems pretty tight.

  2. Very nice. There could have been 16 Big Bangs. Check out the blog on Astronomy at called “seeing into the past.” I want to know what is out there now, while what we are seeing is skewed by x light years.

  3. Finally! They finally publicly acknowledge an alternate possibility – they could of said ages ago that The Big Bang (and many other theories taught in schools as truth) was/is a heavily debated theory.

  4. I like your blog very much,very interesting post, personally I believe in Big Bang Cycles, one after the other.

    The Last Black Hole:
    The End Before A New Big Bang Beginning

    Is it possible that the last ultimate black hole could be the last step before the next beginning and a new Big Bang? I believe so. The following is my theory I call big bangs continuum.

    I think we are in a Big Bang cycle, still expanding and accelerating, but eventually the universe, in my theory, will start collapsing.

    I believe that Black Holes, at the centre of Galaxies, will continue absorbing stars, binary stars, gas clouds, dust, matter, anti-matter, and anything else in it until they will have absorbed the entire Galaxy.

    “Black holes, which form out of the collapse of matter, have such high density that nothing can escape their gravitational pull — not even light. They cannot be seen directly, but their influence on nearby stars is visible and provides a signature,” according to Andrea Ghez, professor of physics and astronomy in the UCLA College.

    I believe, when all Galaxies will have been absorbed by their own ultimate massive black hole, another step will occur: inter-galaxies cluster black holes will form and all galaxies will be absorbed into the next astronomical inter-galactic black hole.

    In my own theory, this black hole cycle will continue until or before all known and unknown matter will reside in the last ultimate universal black hole, at that point all will be contained in this final place and the final collection will be so dense, and collapse in itself into pure energy, when all matter will change form into pure energy that will inevitably create the next big bang and the next universal cycle of life will begin possibly again and again forever ad Infinitum. *

    My own original theory, on this possible eternal cycle, differ with the current established one, where “entropy of the universe”** would be the last step into a permanent conclusion of matter and life.

    My theory by contrast would comply in physics, with the law of conservation of energy which states that the total energy of an isolated system cannot change, it is said to be conserved over time.
    Energy can be neither created nor destroyed, but can change form from matter into pure energy for the next big bangs where pure energy will change again into matter and antimatter.
    I am an optimist and I believe in second, or infinite, opportunities, I hope the universe is no different and multiple or infinite big bangs are given to us.

    1. I believe in Big Bang, too and the new concept that came up with the scientists is truly enthralling, but at the same time it can be quite the opposite because controversy persists everywhere. And thanks for the great piece of information. 🙂
