Russian scientists conducted a new study and were able to discover the edge of our universe, which allowed us to take a fresh look at its structure and the question of the existence of dark energy.
Scientists from the Immanuel Kant Baltic Federal University located in Kaliningrad have developed a new theory, Gamebomb.ru reports. In their studies, they concluded that the universe is not expanding due to dark matter, as previously thought. This process arose because the Universe has a certain edge. Various particles exert pressure on both sides of this boundary, which constantly form in the inner part. This pressure on the edges from the inside leads to the expansion of the universe.
Russian scientists based their theory on the previously known Casimir effect from quantum field theory, Gamebomb.ru reports. He explains the interaction between two uncharged bodies. It is assumed that in a vacuum virtual pairs of particles and antiparticles corresponding to all wavelengths of the electromagnetic spectrum are constantly generated and disappear, but between two closely spaced bodies, particles of one spectrum amplify and others stop appearing. This leads to a difference in pressure in the space between them and from the outside. As a result, bodies begin to attract. In reality, a similar effect was observed by sailors in the 18th century, when, with a weak wind and strong waves, two ships at close range began to attract each other.
Russian scientists believe that the same thing happens in the vacuum of the universe. However, on such a scale the effect is reversed. The pressure inside the boundaries of the universe is stronger, so it expands. This means that dark matter does not exist at all, since the required pressure arises due to virtual particles. Artem Astashenok and Alexander Teplyakov of the Immanuel Kant Baltic Federal University published their theory in the scientific journal International Journal of Modern Physics.
