Scientists are still working to find a way to merge the theories that describe the laws of the macro- and microworld. While Albert Einstein’s theory of relativity explains the behavior of objects at the Universal scale, it struggles to reconcile with quantum mechanics. Many physicists are actively seeking a unified theory to combine these two fundamental areas, with some proposing minor adjustments to the theory of relativity, while others suggest more radical revisions.
One revision to the theory of relativity is the Modified Newtonian Dynamics (Mond), which challenges the need for concepts like dark matter, which although observed in cosmic phenomena, remains hypothetical. However, Mond is not without its flaws, prompting physicists to continue the search for alternative solutions.
A group of scientists from the National Technical University in Athens introduced an innovative approach known as the theory of “blurry” gravity forces. Their findings were published in the journal Progress of Physics, where they outlined their proposed changes to Einstein’s theory. Their hypothesis centers around the idea that instead of continuous, space-time may be discrete, similar to the concept of matter being composed of atoms. This theory has been debated for years, yet there remains a lack of experimental evidence to confirm it due to the minute scale at which these studies would be conducted – in the ballpark of the plank length, which is significantly smaller than the diameter of a proton.
Expanding on this hypothesis, the researchers suggested that not only is space-time discrete, but it is also non-commutatively structured. In traditional geometry, the process of changing coordinates consistently produces the same result. However, in this innovative theory of “blurry” gravity, the outcome of coordinate transformations may vary, introducing a new and intriguing aspect to the exploration of fundamental interactions at microscopic scales near the plank length.
