Research says that cause, not time, is the primary feature of our universe.
Physicists believe that time may not be at all. The researchers argued that time has no place in new formulas for combining quantum mechanics and relativity. SciTechDaily writes about it.
“Physics is in crisis. Over the past century, we have explained the universe using two extremely successful theories: general relativity and quantum mechanics,” said the book’s author. Out of timea physicist from Australian Catholic University Sam Baron.
According to him, quantum mechanics successfully justifies working with the very small world of particles and their interactions. At the same time, the general theory of relativity describes the general picture of gravity and the motion of objects.
These theories are more in conflict with each other. Therefore, scientists believe that they should be replaced by a common one.
In particular, we are talking about the theory of “quantum gravity”, which should explain how gravity works in the smallest dimensions.
“But creating a new theory of quantum gravity was a very difficult task. One such attempt was string theory. It replaced the particles of strings that vibrated in 11 dimensions. However, string theory had some drawbacks. “The theory describes a universe similar to ours, but does not provide any clear predictions that can be tested during experiments. Thus, the theory presented cannot be confirmed or refuted,” the scientists added.
The most popular approach thereafter was the quantum gravity loop. It says that the fabric of space and time consists of a network of very small discrete fragments, in other words “loops”. One of the most powerful properties of the quantum gravity loop is the elimination of time.
“The quantum gravity loop is not the only theory that eliminates time. Some other techniques also eliminate time as a key aspect of reality. There are no tables, chairs or even people in the theories. of physics, but we still know that it all exists.We know very well that all of the above is made up of basic particles, but we have no idea what time it might be “composed.” it can be said that it exists. , “-emphasized the author of the book.
According to him, based on this, there may be no time in any of the available theories.
However, theories have left the cause of the relationship intact. That is, physics says that causality, not time, is the primary feature of our universe.
“We believe that the discovery that time does not exist may not have a major impact on our lives, but it could lead physics into a new era,” the author summarizes.
