Classroom Aid - Dark Matter Candidates (4K)

This clip identifies three current candidates for dark matter: Hydrogen, WIMPs, and Neutrinos.

Amazing, very very well summarized. You rock.

Sir, please update on WIMP failures in last 5 years, from theories to observations (unfortunedly). You video is the best so solid

Correction: Neutrinos travelling faster than light emit Askaryan radiation. Cherenkov radiation can only be emitted by a charged particle, such as an electron or positron.

thanks for explaining how the neutrino detectors work. for the longest time I've been watching these videos with no idea how a lake of water helps scientists see a single atomic interaction. this helps a lot.

Haha, I bet DM doesn't exist, I bet. And am actually rooting for this. I find it too preposterous all the juggling that needs to be done in order to salvage the current theories of gravity. A galaxy is too complex to model, solar systems are much simpler. Then there's the fact GRT doesn't reconcile with Quantum mechanics, when it should. GRT is probably flawed.

Best simple explanation of dark matter.

ive always theorized that dark matter is indeed neutrinos. i read an article in scientific american once (those of you reading scientific american is an EXCELLENT magazine collection, one issued every month, highly recommend subscribing) and was reading about something called neutralinos, could those be dark matter perhaps?

[Scorch]

What about Strangelets or Strange Matter?

Hi David, do you have a preference to which candidate it may be?
