inflation after bigbang

New research goes against inflation theory of the big bang

A team of scientists has proposed a powerful new test against inflation, the theory that the universe adequately expanded in size in a fleeting fraction of a second right after the Big Bang. Their goal is to give insight into an interesting question: what was the condition of the universe before the Big Bang actually happened?

The predominant cosmological model for the universe which has existed from the initial known phases is the Big Bang theory. Through its subsequent large-scale evolution, the big bang model describes how the universe bolstered from a very high-density and high-temperature state and offers an exhaustive explanation for a broad range of phenomena. This includes the abundance of light elements, the cosmic microwave background (CMB), large scale structure and Hubble’s law.

The Big Bang hypothesis is a push to clarify what occurred at the very beginning of our universe. Albeit there have also been too many misconceptions related to space and time. Revelations in astronomy and physics have appeared past a sensible doubt that our universe indeed has a beginning. The theory is just a way of clarifying what actually happened and what did not.


The primal universe was not entirely uniform. There were tiny irregularities in density on infinitesimal scales that became the seeds of the large-scale structure observed in today’s universe. This is the principal source of information physicists rely on to learn about what happened before the Big Bang.

Avi Loeb of the Center for Astrophysics | Harvard said that “No matter what value people measure for some observable attribute, there are always some models of inflation that can explain it”

Now, a team of scientists led by the CfA’s (Center for Astrophysics) Xingang Chen, along with Loeb, and Zhong-Zhi Xianyu of the Physics Department of Harvard University, have applied an idea they call a “primordial standard clock” to the non-inflationary theories, and laid out a method that may be used to falsify inflation experimentally.

Scientists started their experiment by identifying the defining property of the various theories – the evolution of the size of the primordial universe. Through this, they actually wanted to find some characteristic that can separate inflation from other theories.

Admitting that cosmic inflation is well known for resolving some critical secrets about the structure and advancement of the universe, other altogether different hypotheses can also clarify these issues. In a portion of these hypotheses, the condition of the universe preceding the Big Bang, the purported primordial universe was weak and contracting as opposed to extending, and the Big Bang model theory was in this manner a piece of a Big Bounce.

To identify between inflation and other ideas, the issue of deceit has inevitably arisen. Additionally, some of the scientists have also been so curious about inflation implying that its seemingly endless malleability makes it all but impossible to properly test.
