Why Do Neutrinos Have Mass? A Small Question with Huge Consequences

Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do neutrinos have mass?

1:09 “....they just really don’t like to interact with stuff...”

I have found my -people- particles

[evanrigel]

particle physics is so confusing; I'm in awe that these scientists have made these discoveries at all. Hats off to you!

[justsammy]

Omg Scishow you can't just ask particles why they have mass

[danroth]

My hypothesis: the flavors of the hypothetical high-mass neutrinos was just too delicious and they were all eaten in the early universe.

[thereisapricetoeverything]

Such a strange universe we live in, I’m reminded of that every day.

"We don't allow faster than light neutrinos in here, " said the bartender.



A neutrino walks into a bar.

My dad's cousin actually was a part of the team that helped make that discovery that won that Nobel prize. They worked in a salt mine to gather data and whatnot. I'm glad I was able to learn more about what he was able to discover.

thank you sponsors for making the un wealthy, broke man, smarter.

"we know there are 3 flavours of neutrinos"
mmmm blueberry cosmic particles

[ronr]

And this is why I like the Old-trinos.

6:40 "..I'm not drifting off into space right now"

Hmmm debatable

[militantpacifist]

I was going to make a neutrino joke but it will just fly through your head.

[pamelamays]

Everytime we solve one, another seems to pop up.
Basically the plot of the Scooby Doo franchise.

If I remember correctly, in order for seesaw mechanism to be a viable explanation, neutrino has to be a Majorana particle - it has to be its own anti-particle. This could be confirmed by observing neutrinoless double beta decay and there are several experiments going on in search for that (e.g. GERDA).

I'd like a tau flavored neutrino with neuon sauce and electron sprinkles.

[Scientastica]

Fascinating as always! It’s amazing how far into the molecular composition of things we have gotten!

[brianm]

Why do neutrinos have mass?
Well, they're terribly religious, you see, and...

[joshuainopiquez]

"Billions of them are passing through you every second"

Thanks, I feel very conscious of everything I'm touching now

[jacanchaplais]

Super well researched! But you might want to be careful with throwing around that neutrinos have "antiparticles", as that's still an open question. A lot of particle physicists think that they might be Majorana fermions, which means that they are their own antiparticle, and if that were the case it would also help explain the mass issue.
