Physicists have developed a new approach to solving one of the most stable problems in theoretical physics: unifying gravity with the quantum world.
In a modern paper published in the magazine Reports on progress in physicsScientists determine the reformulation of gravity that can lead to a fully compatible description with the quantity-without invoking additional dimensions or strange features required by more speculative models, such as String.
At the heart of the suggestion there is a rethinking of how gravity is made on a basic level. While all electromagnetic, weak and powerful electromagnetic forces are described using the theory of the quantum field-the sporty framework that includes uncertainty and duplication of wave particles- attractiveness Still strange. General relativityEinstein’s theory of gravity is a purely classic theory that describes gravity as falsification of space and energy space. But attempts to mix quantum theory with general relativity often contradicts fatal mathematical contradictions, such as endless possibilities.
The new approach is re -interpreted the field of gravity in a way that reflects the structure of the theories of the known quantum field. “The main result is that our theory provides a new approach to the risk of quantity in a way that is similar to the formulation of other basic reactions of the standard model,” said the author of the study, Miko Portan, a physicist at Alto University in Finland in an email.
Instead of bending at space, mediation is made in gravity in its model through four interconnected fields, with each similar to the field that governs magnetic. These fields respond to the mass in the same way as the electric and magnetic fields of shipping and current. They also interact with each other and with fields Standard In a way that reproduces general relativity at the classic level, also allowing the quantum effects continuously.
Since the new model reflects the structure of established quantum theories, it avoids mathematical problems that hindered historical efforts to employ general relativity. According to the authors, their working framework produces a good quantity theory that avoids common problems-such as non-marketed endless quantities and negative possibilities of material operations-which are usually arising when estimating public relativity using traditional and direct methods.
A main advantage of this approach is its simplicity. Unlike many quantum gravitational models that require undiscovered molecules and additional forces, this theory is committed to familiar terrain.
“The main advantages or differences compared to many other quantum gravitational theories are that our theory does not need additional dimensions that do not have direct experimental support yet,” said Gokka Toulky, a professor at Alto University and co -author of the paper in an email. “Moreover, the theory does not need any free parameters that exceed the known material constants.”
This means that the theory can be tested without waiting for the discovery of new molecules or the review of the current physical laws. “Any trials can be used directly a direct amount to test any (upcoming) predictions of the theory,” Tolkki added.
We look forward
Despite the promising features, the model is still in its early stages. Although the initial calculations indicate that the theory acts well under the verification of the usual consistency, complete evidence of its consistency is still to be solved.
Moreover, the framework has not yet been applied to some of the deepest questions in gravitational physics, such as the true nature of Black hole exclusively Or a large explosion physics. “The theory is not yet able to face these main challenges, but it has the ability to do this in the future,” said Barthenin.
Experimental verification may prove to be more far away. Gravity is the weakest known forces, and its aspects are incredibly hidden. The direct tests of quantum gravity effects are out of the reach of the current tools.

“The test of quantum gravity effects is difficult due to poor gravitational reaction,” said Tolkki. However, since the theory does not include any adjustable parameters, any future experience benefits from the behavior of quantum gravity can confirm – or exclude – the new proposal.
“Given the current pace of theoretical progress and observation, it may take a few decades to take the first experimental breakthroughs that gives us direct evidence of the effects of quantum gravity,” said Partanen. “Informed evidence can be obtained with advanced notes earlier.”
Currently, Partanen and Tulkki work opens a new direction for the viewers looking for a quantum theory of gravity – those that remain based on the successful frameworks of particle physics with some of the most deep puzzles in the universe.
