We are surrounded by matter in all its forms day and night—furniture, houses, trees, and even the air. But, as per physicists, the visible matter well known to us might only add up for almost 20% of all substances in the universe. As per the present theory, almost 80% might be dark matter. This statement is based on various calculations, one of which is that galaxies and stars rotate much quicker as compared to what they might if there were only standard matter that existed in the universe.
Eventually, researchers have designed different theories to clarify exactly what this unexplained dark matter may be composed of. Amongst the possible candidates that come into doubt are WIMPs or weakly interacting massive particles. Scientists have invested many years attempting to find these down with particle detectors, but with no success.
Various years back, on the other hand, researchers proposed an option—a bunch of particles dubbed as axions, which are significantly lighter as compared to other particles. As per the theory, the region of these particles swings, which indicates that it differs continuously. The frequency of this swing is relative to the particles’ weight, and, as this is very low, the frequency should also be less. But nobody recognizes just yet if that is the case.
On a related note, researchers at Cornell University have designed a method developed to envisage models of the universe so as to solve some of greatest mysteries of physics. The method was designed by using scientific standards employed to make models for knowing physics and cell biology to the challenges of big data and cosmology.
“Science operates since things behave much more easily as compared to what they have any right to,” claimed James Sethna, professor of physics, to the media. “Very complex things end up doing very simple communal behavior.”
