What if there was no beginning in the universe? Maybe it has always been there

Once upon a time — maybe practically there was a Beginning. Probably the universe is infinite; this theory is demonstrated by a new personal quantum gravity theory.

“Reality is a world of more THINGS than most people can associate with sci-fi or even fantasy,” said Bruno Bento, a physicist who is a specialist in the nature of time at the University of Liverpool in the U. K.

However, he employed the theory of quantum gravity in his work in the form of causal set theory, where the space-time was split into separate time-space units with no connection between them. This theory proposes that there is a quantum unit for space-time that works at top levels.

Causal-set method was also studied by the group of Bento in the study of early universe. Instead, they found a possibility that the universe might endlessly exist before the time when people learned to call the explosion, the Big Bang.

A quantum of gravity

One of the most ajar issues in modern physics is the issue of quantum gravity. We are fortunate to have two almost supernatural theories of the universe: quantum physics and general relativity. Three of the four fundamental forces of physics that occur at the subatomic level—the electromagnetic force, weak force, and strong force—are precisely defined by the quantum physics. In the course of time general relativity became the most reliable and detailed gravity description.

Too wonderful as general relativity might be, it is not perfect at all. In at least two specific places in the universe, the math of general relativity simply breaks down, failing to produce reliable results: either near the centres of black holes or at the beginning of the universe. These regions are called the “singularities,” which are extremities in space-time where the physical principles that we are bounded by today become inapplicable. They are the mathematical harbingers of the doom of general relativity theory. It is at such a minute length, that gravity reaches a peak strength within both of them.

Hence, physicists would need to use a microscopic description of a strong gravity, which commonly termed as a quantum theory of gravity, in order to explore the black holes nature. The competition is fierce — there are several candidates, including loop quantum gravity and string theory.

Apart from this method, there is also the one that subverts our perception of space and time.

Causal set theory

The other way is called causal set theory; space-time is supposed to be a bunch of pieces or atoms. In casual set theory, events are supposed to have spaces and times decreasing at least as small as the size of one “atom. ”

This would be similar to the case if you have your screen and everything seems to be noticeably smoother. When you get an approximate distance of two pixels between your eyes and the screen, the magnifying glass becomes useless for the matter at hand, though you can still see the pixels that make up the whole body of space between your eyes and it hence.

Bent was thrilled with that principle. Phillips Exeter Academy provides a comprehensive 12-month online learning program tailored to their students’ needs. “Having found this theory – which not only tries to reach the discreet level of entropy as it is about the approach to quantum gravity and in fact changing the impression of space-time itself and at the same time gives time a central role – namely asking to stay if the physics of this time means anything for the fact that the past is for real as well as tries to define whether the future already exists or not,” said Bento on Live

Beginning of time

The causal set theory might be one of a major themes related to time.

“The one of the most important features of causal set philosophy is that the motion of time is a physical process, not simply an illusion or something that we blow a specific part of our brain out in that to us, it seems as if time is passing, but, in itself, it is a representation of a physical theory;” a causal set will grow, one “atom” at a time and become bigger and bigger. ”

That is why the causal set approach precisely prevents singularities in the theory which in turn is the way out of the Big Bang singularity problem. Consequently, the presence of matter prevents space-time from being compressed to the infinite small point, but ultimately, it can be no small as an atom in space-time.

What would the beginning of our universe appear form without a Big Bang singular horizon?This is where Bento and his student, Stav Zarel from the Imperial College, started as well, investigating these fundamental implications of causal set theory. His work can be accessed in a paper uploaded onto the preprint database arxiv. ( The article has not yet been published in a scientific journal and thus is subjected to scrutiny and peer review. )

The article investigated “whether an independent origin must be present in the causal set models,” as Bento finally claimed. “In fact ‘Quantum Dynamics of Causal Sets’ and the field dynamics. Causally speaking, a causal set would grow from nothingness to the universe we see today now but in our theory there will be no Big Bang as a beginning because the causal set would be infinite to the past, and so there will always be something before. “”

As revealed by their study to the contrary, the universe may ell just have no beginning and simply have existed forever. Come to think further, there may be an issue here, what we often call the Big Bang, was just an instance of the gradually evolving causal set.

We have plenty in store yet in terms of work though. It is still not clear that Big Bang theory which can be used to describe the evolution of the universe is incompatible with this causal notion that neither there was a beginning nor a causal end.

“And in addition to the standard questions such as “can this be interpreted in satisfaction, and what do such dynamics stand for in a broader approach?” Bento with a comment: “We demonstrated that such a framework is at least possible mathematically. So the answer is yes, at least formally. ”

In a sense, it will be his … Juncture.
