Neutrinos: Messengers from a Violent Universe

In this 45-minute presentation Alex Himmel, Wilson Fellow at Fermi National Accelerator Laboratory, explains how neutrinos might provide the answers to many questions that scientists have about the universe. The neutrino is a type of subatomic particle. They are produced in copious quantities by celestial objects -- trillions of neutrinos from the sun will pass through your body while you read this sentence -- but they interact so rarely with other particles that only a handful will strike an atom in your body during your entire life. Yet these benign little particles can tell us about some of the most energetic processes in the universe. In order to detect these elusive particles, scientists build enormous particle detectors deep underground, using tanks full of liquid argon in an old gold mine as well as a cubic kilometer of Antarctic ice. In this talk Himmel works his way from the sun to galactic supernovae to the possible extragalactic sources of the highest-energy neutrinos ever observed. Himmel also answers audience questions from members of the Naperville Astronomical Association.

Really interesting topic but ruine by the speaker saying "right" every fifth word, drove me crazy.

[@erikvanvelzen]

I am not a physicist nor an astronomer but I found this interesting and accessible and it taught me a lot about neutrinos. Good job of Alex Himmel.

[@sergiospitia605]

I wanna thank for this detailed and crystal clear presentation for ordinary people.

[@philswede]

Thanks for an awesome talk!

[@czechthisout]

the questions these guys are asking are really impressive. it really shows that whoever the audience is are critical thinkers.

[@openyoureyesandseethefutur3382]

thanks, your enthusiasm for neutrinos, is super!

[@vicplichota]

One of the most in-depth public talks I've ever seen -- thanks!

Greetings from Lead, South Dakota, home of the former Homestake mine (and current home to the lab!)

[@richardsrichards2984]

Please fermilab more 1hr duration talks...good talk

Without a doubt the neutrino when put into a working model of "E" moving Itself through time via Mass Oscillation creating a byproduct of particle matter along the way holds the key to answering all the major mysteries in physics and astronomy to hand over to all fields of science. And

Nice

[@lpbowd17]

I was so focused I didn't notice Alex use the word right.

Neutrinos are like oven timers, letting you know when where and why the data goes dark.
