Physicists develop new theories that can ultimately unify gravity with other fundamental forces

In theoretical physics, which may prove to be a groundbreaking advance, researchers at Aalto University have developed a revolutionary approach to understanding gravity that can solve one of the most enduring challenges in the field: how to reconcile Einstein’s theory of gravity with quantum field theory to describe the natural fundamental forces of other fundamental forces.

The new theory is called “Uniform Gravity”, which is a comparison with the previous quantification of gravity by introducing the concept of the “Spatial-Time Dimension” field and the use of concepts similar to the mathematical structures that successfully describe the other three fundamental forces in the standard model of particle physics.

“Our goal is to bring gravity theory to the specifications of the standard model,” explained researchers Mikko Partanen and Jukka Tulkki in their paper in a report on advances in physics.

Unlike previous methods that relied on non-compact, infinite dimensional symmetry, unified gravity utilizes compact, finite dimensional symmetry, called u(1) instrument symmetry. This approach reflects a proven mathematical framework that has been so successful in describing electromagneticism and strong and weak nuclear forces.

The theory is based on a new way of understanding how space-time itself emerges from the underlying quantum field. The researchers introduced what they called the “space-time dimension” field, which allowed them to extract four-dimensional space-time quantities from eight-dimensional mathematical structures called rotators.

One of the most attractive aspects of the theory is that it does not introduce any new free parameters other than the physical constants determined by previous experiments. This extraordinary property contrasts sharply with other proposed quantum gravity theories, such as string theory, which often involves many unverified parameters.

“The theory is expressed based on known physical constants, and all results are quantitative and can be compared directly with possible future laboratory experiments or astronomical observations,” the researchers noted.

The classic limit of unified gravity is equal to what physicists call “the mutual relationship of remote relativity”, which means it is consistent with all established observations and experiments that have been confirmed by Einstein’s general theory of relativity. These include attacks on mercury orbits, bending of light around the sun, and latest measurements of gravity waves.

Perhaps most importantly, the researchers show that their theory seems to be redistributed at the quantum level, at least in perturbation theory at most one ring of order. Gravity has been a persistent obstacle to previous quantum gravity theories because it determines whether a theory can provide meaningful predictions on all energy scales without producing mathematical infinite attitudes that make the calculation impossible.

Professor Turki stressed that they still need to extend their miscalculable proof of ability to all circular orders, but the consistent mathematical structure of the theory strongly suggests that this should be possible. “The dimensionless coupling constant of unified gravity strongly suggests that the theory is reassignable,” he explained.

In addition to potentially solving theoretical problems, unified gravity can ultimately help answer profound questions about the most extreme environments of the universe, such as the interior of a black hole and the first moments after the Big Bang.

The theory also makes specific predictions about how gravity will modify quantum effects, which can be tested experimentally. For example, the researchers calculated how gravity interactions will facilitate correction of Coulomb potentials, magnetic moments of electrons, and even scattering of fundamental particles.

Although the mathematical foundations seem promising, researchers acknowledge that there are still major challenges. Due to the weakness of gravity interaction, the lack of experimental data on quantum gravity has made limited progress in the field. However, as experimental techniques develop, there may be an opportunity to test some predictions of the theory in the coming years.

Physics has long been seeking a consistent theory of gravity that will accomplish our understanding of fundamental forces. If unified gravity can be further theoretically reviewed and experimentally tested, it can represent the crystallization of this task, ultimately bringing gravity into the same theoretical framework that very successfully describes other fundamental forces of nature.

After extending the theory’s re-standard proof to all circular orders and further understanding of the theory’s non-perturbation regime, physicists may eventually end up with the tools long-seeking to investigate the areas of intense gravity in black holes and conduct research at the beginning of possible. ”
