Comment Dark matter, heavy neutrinos and anti-matter (Score 1) 274

I've seen some speculation that dark matter could be a previously unseen heavy neutrino. I also understand based on current theories there should be a lot more anti-matter than is seen now in the universe. So my armchair physics idea is there was some reaction as part of the matter/anti-matter annihilation in the early universe that converted a lot of the anti-matter into the dark matter forms of heavy neutrinos. Has this idea been pretty much ruled out already?

So transistor is a finite state machine is a computer. Well I've got a jar of pennies where each one is a finite state machine and therefore each one is a computer. Or else maybe they should start teaching more engineering and less computer science.
