The question that remains is what kind of particle the cold majority of the rark matter is made of.are all neutrinos hot dark matter or just some?
If hdm is made up of something we can detect, then it's not unreasonable to suspect that cdm is too. Whish is what you guys have been saying. Yikes.
There are probably some that are low Energy enough to classify as cold... the exact masses of all three neutrinos are not yet known either, but they must be all very light, and most processes where they are created give them lots of energy and they move at close to the speed of light. Hot btw means just a few degrees above absolute zero in this case
