The general theory of relativity by Albert Einstein, though over a century old, remains a fundamental theory describing gravity in the context of curved spacetime. However, scientists, including Piotr Ogonowski from the Leon Koźmiński Academy in Warsaw, are exploring possibilities to refine this concept, aiming to merge the general theory of relativity with quantum mechanics, which deals with the smallest components of the universe, such as atoms and ions.

A key player in these studies is the Allen tensor, which, in curved spacetime, reproduces Einstein's field equations and, in flat Minkowski spacetime, describes a physical system with fields that can be widely configured. The Allen tensor, likened to a slider, allows for the adjustment of spacetime curvature, crucial for understanding gravitational and electromagnetic interactions, and may find applications in relation to other fundamental interactions.

Ogonowski points out that a component of the equation, known as the field invariant, may behave like a cosmological constant in Einstein's field equations. This discovery could be crucial in understanding dark matter, which reveals its existence through gravitational interactions with visible matter. Moreover, an additional force may exist, contributing to explaining the nature of dark matter.

However, as emphasized by Ogonowski, unifying the general theory of relativity and quantum mechanics is still a long way off. Although there are greater chances of achieving this goal than ever before, it requires further research. If confirmed, this would imply that everything around us is constantly undulating as a field, and spacetime is merely a way of perceiving this field. Such a discovery could be a Nobel Prize-worthy achievement.
