the theory of everything; A relationship for all the laws of the world (Persian subtitle)

Until now, in various fields of physics, various relationships have been proposed, each of which describes their range well, but scientists are looking for a relationship, or in a better word, a theory that can cover everything from the smallest subatomic particles to the largest galaxies and galaxy clusters. to describe The theory of everything.

Scientists have been able to investigate various phenomena at various scales. But they have found that the relationships governing these scales do not match perfectly.

In fact, the structure of modern physics is divided into two columns. Classical physics, which includes the theories of Newton, Einstein, Galileo, and other people who propose gravity, deals with the movement of large objects from the objects around us to stars and galaxies, and quantum physics, which deals with the interaction of subatomic particles and has its own rules. /p>

Although these two fields are not currently compatible, Einstein believed that there must be a way to reconcile the two. It should be a theory that connects the subatomic world with the world of massive objects and creates "Unification". A theory that can really predict everything, and for this reason it is called "Theory of Everything".

At the end of the 20th century, Stephen Hawking made significant progress in this field. . He stated that although nothing, not even light, can escape from a black hole, black holes lose mass over time and release energy. What is known today as Hawking radiation.

Hawking used a quantum explanation for such a theory. In other words, he reached such a conclusion by integrating a quantum principle with the concept of gravity. What is known as quantum gravity or the "standard model".

Although we have not yet achieved the theory of everything, researchers have made significant progress in this field. Including the "String Theory" which states that all subatomic particles such as electrons and quarks are composed of small vibrating strings that cause different properties with different vibrations.

In order to test the string theory, people use various ways. It has been tested and has achieved significant progress such as the discovery of the Higgs boson particle. But it still has a long way to go in answering its questions, which Aperture reviewed in this video.
