Want To Know What Existed Before Big Bang ?

There are both scientific and non-scientific varieties of the views about what came before the Big Bang. Some say there was nothing at all and a few say a black hole or a multiverse. But now a team of mathematicians from Canada and Egypt has evaluated some progressive scientific theory and a compound set of equations to find what came first the universe in which we live. Their research paper has been published in Nature.






To describe it in simple and certainly understandable terms; they applied the theories of the tiny i.e.from  the world of quantum mechanics, to the entire universe - described by general theory of relativity, and revealed the universe principally goes through four different periods.

More importantly, they discovered what came before this universe. Another universe or more precisely another ‘cosmological phase’.

Regardless of being infinite in size our universe is cyclic and has always been there in one of four stages.

The universe is expanding, and the expansion is accelerating, but the team considers that certain alteration driven by quantum mechanics will eventually stop the expansion and pull the whole lot back to a near infinite point – at which stage the universe will eventually start expanding again.

The paper, called ''Non-singular and Cyclic Universe from the Modified GUP'', written by Maha Salah, Fayçal Hammad, Mir Faizal, Ahmed Farag Ali, is very much complex but Prof. Mir Faizal outlined the conclusions of this paper.

According to Mir Faizal, they have assimilated quantum mechanical effects in cosmology using a methodology called the modified GUP.




This methodology deviates the equation for cosmology in a fascinating way. It predicts four distinct phases for the universe - the present phase of the universe being just a part of those phases.

There is a phase before the big bang in this cosmological model, and it is very much possible to know about that phase of the universe by going through the physics of current phase of our universe.

Professor Mir Faizal said:

"In our cosmological idea. the universe did not start with the big bang, but there was a phase evolution from one phase of the universe to another. This is possible because the universe can exist in four different phases like water can exist in three different phases. Just as we can know about the properties of ice, by studying the properties of water which has formed from it, we can know about pre-big bang cosmology by going through the physics of this universe."

In their model, they were able to study the pre Big Bang state of the universe. The equations in their model calculate that the expansion of the universe will come to a break and then will instantly be followed by a contracting phase.

Prof Mir added:

"When the equations are generalized beyond the extreme rate of contraction, a cyclic universe state emerges. “Other cosmologists have suggested a big bang and big crunch picture – but those models have singularities. Singularities are not good in physics as they point out a region where the laws of physics collapse, and at such regions, one cannot use physics to get reasonable results. This new cosmological model does not deal with such singularity. The big bang singularity can therefore also be avoided by using the improved GUP-corrections to the cosmology."




In their cosmology model, the repeated nature of the universe occurs as a result of integrated quantum effects into a cosmological model of the cosmos.

Prof Faizal clarified that though there are many different mind-boggling procedures to quantum gravity, e.g. string theory and loop quantum gravity, what these different procedures have in common is that there is a minimum length below which there is no space.

Several of these approaches also predict that there is also a maximum energy and no object in the cosmos can have energy beyond that maximum energy.

The research team assimilated the effect of having a minimum length and a maximum energy into a cosmological model, and then they ended up with a repeated universe.

Asked about the philosophical and even more possible theological implications of his work Prof. Mir said:

"No one concludes any philosophical or theological suggestions of a finite or an infinite spatial dimension, and time is just another dimension, so why should it be treated any differently.  Anyhow, I do not believe in a God of gaps, with the big bang being a big gap, but in a God who made the mathematics explaining reality so perfectly that there are no gaps, not now and not at the big bang."

  1. Very cool! This sounds like basically what I've been thinking for a while.... :)
