Quantum gravity theory revives ancient ideas "a universe without beginnings" - New News

The “big bang” or the massive expansion of things 14 billion years ago. Many believe that this is the origin of the universe. It’s hard to imagine that without the Big Bang, would there still be a universe that gave birth to Earth and humans like us?

Recently, a physicist from the University of Liverpool in the UK. Sophisticated concepts such as quantum gravity (QG) were used to prove the possibility of the existence of the universe as we have always seen. As it turns out, there is no beginning or big bang. Or if the Big Bang actually exists, it is a consequence.

This unconventional idea is tantamount to reviving ancient beliefs in some cultures that the universe is eternal without origin and may never die.

A new theory of quantum gravity

Bruno Bento, a physicist studying the nature of time at the University of Liverpool. The author of the above research, now published in the online academic archive arXiv.org, says he has developed a new theory within the framework of quantum gravity. Named “Kossel Set Theory”

According to the new theory, space-time can be divided into smaller and smaller units until there are fundamentally indistinguishable units of space-time. Like the atoms of the elements, we can use this basic time-space to find the origin of the universe or the universe itself.

According to the theory of relativity, space-time is woven together into a continuous piece.

The causal theory was developed from the concept of quantum gravity. This is because such quantum concepts can explain physics problems at the particle level. Einstein’s theory of general relativity cannot be explained. Including the problem of “singularity” (singularity) or gravity at the smallest point of infinite density. They are found only in the centers of black holes and at the beginning of things like the Big Bang.

Dr. Bento thought that at the basic level space-time could split like atoms, without a continuous weave of a fabric as we imagine the universe and the real world today. The possibility of when and where two events follow each other. Will be limited immediately

A new perspective on such space-time is like looking in a magnifying glass on your computer screen. This will result in an enlarged image that immediately separates from the rest of the screen. Unlike the naked eye, all screen images are connected together.

There is no beginning of time

Dr. Bento also explains that considering the causal theory, the passage of time is characterized by a wide range of physical features. Instead of being an abstract or an illusion. ”

“Under this conceptual framework, the universe is only the development of one elementary unit of space-time. As a primary particle gradually grows larger, there is no unity or infinite origin in this state, because there can never be anything smaller than the size of the primary space-time.”

“Such a theory is mathematically practical. This means that neither the origin nor the Big Bang is a precondition for the existence of the universe. There must have been something long before the Big Bang.”

“Our study shows that it’s infinitely long and infinite. The Big Bang was not a start. It’s just a step in the evolution of the universe,” Dr. Bento concluded.
