What is a Neutrino - the Most Mysterious Particle in Modern Physics?

In today's video, we will attempt to understand what a neutrino is, the role it plays in the universe, what we know and don't know about it, and why these particles are considered the most mysterious and paradoxical among all known elementary particles in physics.

UPD: I drew the reactions incorrectly at 11:05: the protons and neutrons in both reactions need to be swapped, and it is the upper reaction that should be crossed out, not the lower one. In the narration, I explain everything correctly, but the diagram is wrong.

This may be the best video on neutrinos I have yet seen on YouTube so far, and believe me, I've been searching.
Yes, I would like to know more, please!

I had not been able to understand the reason for 3 different neutrino masses until this video, thanks.

[mikkel]

Great video. Finally informing about other explanations than oscillations.
More please.

[davevann]

More please. Great detail on the current knowledge about neutrinos. More details would be great, including gaps in our knowledge, new ideas, new and planned experimental equipment, where neutrinos might get mass, and how and why neutrinos fit into the standard model.

As a person who studied neutrinos in undergrad and now doing research in a different type of particle for a PhD, this video is very enlightening and informative while being interesting through and through. I would love to see more videos about neutrinos and possibly about rare B decays (which is what I am studying right now)

I appreciate the attempt to create educational science videos but the use of AI voice and stock video makes this feel very generic. There are dozens or perhaps hundreds of other videos and channels dedicated to this sort of content, without the shortcuts in creating the content. You need to offer something more substantial if you want your channel to grow into something worthwhile. Just my two cents.

Excellent video!!! I look forward to additional info on neutrinos physics from you. Please accept my sincere thanks for your great efforts!!!

1 neutrino is positive 1neutrino is negative 1 neutrino grounds the other 2 so charge can be held. Once this charge is used the separation occurs. This makes most sense in my opinion. Peace ✌️ 😎. Alex 79suited. Great video, Thanks.

Excellent summary. And if the voice is AI it us a very good one. Saying leed instead of lead was the only slip that i picked up and a living voiceover would probably have made a few more given the subject matter ! AI will be the end of us all

What IF the neutrino mass is negative? Oscillating from tiny positive mass to negative. Meaning they would travel faster than light while having negative mass, and possibly be a key to gravity

[atomhydrogen]

All is known about neutrinos. This is explained in paper of this year entitled “ Direct derivation of the neutrino mass “.

[arlenestanton]

What kind of math would I need to study to have deeper understanding of this neutrino theory?

[davidelghammer]

1 neutrino 2 neutrino 3 neutrino Four!
Find more particles! I implore. 😜🙄😁
I love particle physics...

[ioanbota]

Realy I like this video so so much like you can imagine

There are about 10^{22} stars in the universe with an average neutrino flux of 10^{50} neutrinos/second/star. Assume that production is constant for the last 14 billion years = 4.42 x 10^{17} sec. With no neutrino sinks, 4.42 x 10^{89} neutrinos presently exist in the universe. Assume each has energy of one Mev=1 amu= 1.66 x 10^{-27}$ kg/amu. (take it as one ev if you like), then the present mass of neutrinos in the Universe is
7.3 x 10^{59} tons. This is considerably more than the present estimated mass of the Universe which is about 2 x 10^{49} tons. Either neutrinos have sinks, or they do not exist.

Do we know if they have the same charge strength or are they different

[SavvaLevkovich]

Спасибо за такие видео, хорошо понятные объяснения и любопытные темы. Интересно, а вилика ли вероятность что в нейтрон одного из моих ядер поподёт электронное антинейтрино и я стану чуточку положительно заряженние 🤔. (Читать субтитры - хорошо, но слушать Ю.Ткачёва лучше👍)

[kirbyschneider]

A lead shield? Or did she mean lead shield?

[andrewpotapenkoff]

Dear Terra Physica, i'm struggling to understand what is 'Energy'?
Humanity is perfectly capable to handle Energy well, but what exactly is it?
What transfers from one particle to another?

I haven’t watch the video yet. Is the misspelling in the thumbnail intentional, like Inglourious Basterds?
