More Big Bangs may be on the cards, scientists say

There had always been theories that mankind’s understanding of the Big Bang theory may have been too vague.  

We have all heard of the Big Bang theory. Now researchers warn there are more to come. A scientific model that enlightens us on the origins and evolution of the universe, the Big Bang theory says the universe began 13.8 billion years ago.

Theoretical physicists at the University of Portsmouth suggest in a yet-to-be peer-reviewed paper that dark energy considered the mystery stuff behind the expansion of the universe, is likely to switch on and off. This, according to the paper, may eventually lead to the next Big Bang.

Mystery yet to be decoded

The mystery behind the Big Bang theory is yet to be decoded.  The researchers hint that dark energy would always have been part of what they call the “push-pull dynamics”.

And they believe, the Big Bang was perhaps only one such instance of many similar atomic movements called “Big Bounce”.

In simple terms this means that dark energy can eventually cause a “big crunch” which may trigger further big bangs. These processes are likely to continue repeatedly.

The drawback with the dark energy model is that researchers need to artificially insert a value to describe or explain the rate of expansion of the universe, adhering to quantum mechanics. But the scientists feel the analysis may serve as the platform for building more constructive models in this regard.

There had always been theories that mankind’s understanding of the Big Bang theory may have been too vague.  That is why they referred to the big bounce – rather than the Big Bang – as the trigger for the origin of the cosmos

It was against this backdrop that the Planck spacecraft of the European Space Agency began measuring cosmic microwave background (CMB). The CMBs are electromagnetic remnants which date back to the early periods of the universe’s existence. 

New theories on Big Bang doing the rounds

There have been many theories doing the rounds following the findings of the Planck spacecraft, but all researchers would want to scan the universe in a condition right after the Big Bang to come to any definitive conclusion on the origin of the universe.

In other words, despite all the technological advances, we would need more profound studies on the nature of the universe right after it was created or originated.

Some scientists are also against this theory, as they doubt even if we have a peek into what it was soon after it came into existence, it would still be a gigantic task to ascertain what happened before it.
