To that end, several models have postulated that this mysterious material might actually consist of a revolutionary fundamental particle known as an axion.
Research indicates that it could play a part in many interfaces, particularly those between matter and other exotic forms such as radiation or gravity.
23. It is also possible that Dark Matter could be composed of more than one type of particle.
Recent research suggests there is more than one candidate for what dark matter could be made of. Scientists widely speculate that the answer to this is yes, believing there are multiple possibilities.
As refinements in our methods become sharper, new theories and explanations suggest that each type of observable particle must point strongly towards a multiplicity of dark particles.
24. Some theories propose that Dark Matter could be fluid with negative mass.
Select a post first
Certain theories suggest that dark matter, the source behind an estimated 85% of the universe’s mass, could be a fluid possessing negative mass. This hypothetical force is known simply as “dark fluid.”
This proposition effectively suggests the possibility of dark energy counteracting ordinary energy, potentially resulting in a greatly balanced or even canceled-out universe. If proven true, this idea stands to revolutionize how we understand gravity as we currently know it.
25. Another proposed form of Dark Matter is the so-called fuzzy dark matter.
One of the fun facts about Dark Matter is that Proposed solutions to dark matter have extended far beyond the conventional. One such example that has come to light, so to speak, is “Fuzzy Dark Matter.”
