- nonbel 10y agoWell, ok. But apparently someone at NASA thinks it is plausible. Argument from authority heuristic tells me to listen to them rather than you in this case. Since you are not coming with any links or specific argument against what was said there, that is pretty much all I have to go on.
- petewailes 10y agoPrimordial black holes are the candidate here as you mentioned (black holes exist, primordial black holes may exist, but we haven't found any yet). Thanks to LIGO we think we may have the first evidence for them, but there is still a lot of work to do to prove them. Decent article on that: https://www.sciencenews.org/article/ligo-black-holes-dark-matter https://www.sciencenews.org/article/ligo-black-holes-dark-ma... The interesting thing will be if we can prove they are around, which would then give some options for showing if they're dark matter or not (looking for gravity waves in areas where there's large dark matter concentrations would be the most likely candidate for now).
