There seems to be not enough mattersmatter to account for the fact that the speed of some stars located far away from the galaxyGalaxy center moving atis almost the same speed as those stars found nearnearer to the center of the galaxyGalaxy, therefore it seems there should be even more mattersmatter: so thesethis missing matter is coined infamously astermed dark matter. There is a kind of stellar object that isn't massive enough to produce its own light but is many times more massive than Jupiter, a.k.a brown dwarf. Since it isn't bright enough to be detected by our deep space telescope nor the earth bound counterparts, therethey should be numerous of them in every galaxies as I believe these objects sits in the middle range between planets and stars. However it seems the scientific community had ruled out this potential dark matter candidate without scanning the unobservable milky wayMilky Way galaxy as well as billions other with different light spectrums. Why isn'taren't brown dwarf qualifydwarfs considered candidates for the mysterious dark matter?
