Can You Believe It? #31 How Many Neutrinos Pass Through Our Body Every Second?

[@andalucian7434]

Not all heroes wear capes. You are living proof of that mr Biezen. Thx for the video

[@MichelvanBiezen]

Thank you. Glad you are enjoying the videos. 🙂

[@innovationsforall]

@@MichelvanBiezen cape next time :)

[@andalucian7434]

@@innovationsforall hahah that would be a fantastic idea

[@Megatron118x]

I remember learning about this in one of my physics classes for my major in college years ago. Fascinating stuff! That underground water detector facility in Japan to detect neutrinos has always intrigued me too

[@MichelvanBiezen]

Yes, it took 30 years to unlock the secret of the missing neutrinos! 🙂

[@JH-ux1re]

@@MichelvanBiezen what’s that? Can you make another video to talk about it? I’m a coming sophomore of physics. I know so little and want to absorb as much as possible.

[@MarioDallaRiva]

I think my wife called me a big bag of emptiness only yesterday! These explainers are brilliant, thanks professor 👏🏻👏🏻

[@MichelvanBiezen]

You should hear what my wife calls me. 😂😂

[@toml-oq1vw]

The way he said "virtually" none of them interact...out of that many. Wild

[@MichelvanBiezen]

Wild indeed!

[@fizixx]

Yeah, that's pretty amazing! A friend of mine does research in this area, and has contributed to building, not just the detectors, but the entire tanks they use for detecting neutrinos. It's really interesting. This is a great video and put this into perspective really nicely. :)

[@MichelvanBiezen]

Very cool!

[@JH-ux1re]

What kind of research you friend does?

[@fizixx]

@@JH-ux1re Dark matter originally, but he started working with with neutrinos. He designed, or built the detectors, and he had involvement in the construction of the tanks used to 'capture' neutrinos, or maybe a better way to say it is 'detect' their presence.

[@JH-ux1re]

@@fizixx that sounds very cool. I wish I could know more details. I’m a coming sophomore of physics and very curious about the universe and dark matters! Thanks a lot!

[@fizixx]

@@JH-ux1re That's good though, so do a lot of reading, watch good videos, like this one, and carry on with your studies. Find what appeals to you most. Science can always use talented people. Best of luck :)

[@sombrero9738]

I read an article where they claimed that there are so many neutrinos created during a supernova, that those neutrinos would kill all life on the planets orbiting that exploding star. Death by neutrino Would be interesting seeing if you could do a video on the insane amount of neutrinos of a supernova compared to our sun.

[@MichelvanBiezen]

That is a great idea. We'll add it to the list. Thank you. 🙂

[@zakirhussain-js9ku]

While Neutrinos have mass & magnetic moment, they are said to have no electric charge. Electric charges produce Magnetic field. How can Neutrino have magnetic field w/o electric charge. I think as a stable particle neutrino(also photon)must have mass, electric & magnetic charge like electron & positron.

[@MichelvanBiezen]

If the neutrino has a magnetic moment, it is too small to be measured with current instruments. It may be more of a theory than a determined fact.

[@JH-ux1re]

Very interesting! Thank you! What if because we are hit by neutrinos every single second we eventually age and die?

[@MichelvanBiezen]

Since neutrinos very seldom interact with any of our atoms in our body, they do not have much effect on damaging or aging us. But if we were to live close to a supernova explosion, that may be a different story. (I'll have to calculate the effect of that).

[@JH-ux1re]

@@MichelvanBiezen Perfect 👍 it makes a lot of sense! Thank you!

[@sailorguy9288]

Amazing video .. But do deserve more views .. Good luck

[@MichelvanBiezen]

Thank you. Glad you liked it. 🙂

[@pranavamali05]

Great fact thnku

[@MichelvanBiezen]

Something we don't think about in our every day lives, but it is quite remarkable.

[@pranavamali05]

@@MichelvanBiezen yup

[@bbartt80]

If there's 3.6x10^38 atoms converted every second and you need two protons (H atoms) to produce 1 neutrino, isn't like 1.8x10^38 neutrinos produced each second? Not that this difference matter much with 10^38 factor thou :)

[@MichelvanBiezen]

You are correct. In the proton proton chain 2 of the 4 protons are converted to into neutrons and only 2 neutrinos are produces. So the final number should be divided by 2.

[@mapleext]

So you would say trillions of neutrinos pass through us per second and some small number of them actually strike us on a molecular level? They also mostly pass through everything, right?

[@virginiatyree6705]

Oh great, another dang thing to worry about. As if, there isn't enough going on. It's enough to discourage a human. Thanks for posting & informing me about this topic. v

[@MichelvanBiezen]

Luckily most go right through our body without colliding with anything. And the few that do collide with something in our body, we can handle that. 🙂

[@virginiatyree6705]

@@MichelvanBiezen , I thought it was interesting that a nutrino may interact at the molecular level without a significant effect. Maybe, humans have evolved with the help of nutrinos, maybe. The universe is a fascinating & mysterious realm to exist in; I am happy & have immense gratitude for the life I have...v

[@MichelvanBiezen]

Life is indeed an adventure, full of discovery and experiences.

[@alianjohnson6035]

so that's from our sun, are there neutrinos hitting us that come from other suns further out in the galaxy? great video by the way.

[@MichelvanBiezen]

Thank you. Yes, but in much smaller quantities, since the stars are so far away. They will have been dispersed over a much greater area.

[@alihms]

​@MichelvanBiezen The neutrino effect of 1 star located light years away is small. But since almost all neutrinos can travel far without hitting anything, wouldn't the effect add up? Neutrinos from stars, galaxies, supernova explosions including those at the edge of observable universe can reach us pretty easily. Much much more than that from the sun. Is this correct?

Lucky you! 🎉 congrats 🎉🎉🎉 v
