Physicists are getting closer to the discovery of the secrets of the Universe, but until complete Understanding is still far . Riddles, such as dark matter and dark energy, still remain unknown, and some researchers call the search for the theory of everything (toe) useless.
The theory of everything implies a single law uniting all the well-known forces of nature. However, this idea causes disputes among physicists.
“Speaking about the unity of all the forces of nature into one, physicists imply the unification of four fundamental forces,” explains Katherine Frieze, professor of physics at Texas University in Austin.
These four forces include electromagnetism, gravity, strong and weak interaction. They explain the phenomena that we see around us, but do not give a complete understanding of the universe.
The theory is not able to explain absolutely everything. She cannot tell why someone prefers more cucumbers in a hamburger or is afraid of clowns. She can even be unattainable in practice.
However, some scientists are still confident in the possibility of finding a theory that describes at least a limited “everything.” Frieze, for example, remains optimistic: “The opening of TOE will change things as large fundamental discoveries always do.”
The problem is that gravity, unlike other forces, is best described by the general theory of relativity of Einstein, which contradicts quantum mechanics. This creates serious difficulties in finding a quantum version of gravity.
Nevertheless, scientists continue to look for new ways to unite theories. One of them is string theory, the other is quantum gravity in loops. But both of these theories are faced with their problems and criticism.
The search for the theory of everything can seem hopeless to someone, but it continues to inspire physicists around the world. If scientists someday can open it, this can radically change the course of human history. Or, perhaps, it will simply offer new ideas for areas that are far from our everyday experience. However, this search, of course, will lead to large scientific breakthroughs on the way to understanding what makes space work.
