the fact is over the past 40 years in all observations and experiment in known particle physics we still don’t know what 80% of the mass in our universe is composed of because in the long history we still have no conclusive evidence or result.
The nature of Dark Matter is the study of strange Masses of particles.
Out of the standard set of particles which include protons, neutrons and electrons. Now in the set of modern particles already known to us are 3 main exotic candidates
Hypothetical Candidates for dark matter: Neutrinos, WIMPS (Weakly Interacting particles), Axions. Ultra small particles considered to be the prime suspects in dark matter can only be imagined and hypothetically pixelated in an event of #Microlensing- this is when cosmic object distort light from something behind them. this phenomenon is a rare event
~these particles that can’t be seen with the naked eye can interact and radiate with nothing and are so small that in Super symmetry theory are described to be -100 billionth the mass of an electron mass and can be hypothetically seen by predicting the theory of nuclear fusion properties interacting in huge reservoirs of liquid Zenon nuclei magnetic cloud field in a small chamber in a lab to hypothetically turn extreme light particles like axion particles to photons that return light signals.
