Very impressive. 👍 😀
I wonder what the physicists will learn from it?

I read this in the voice of Todd from Project Farm

Any idea of what they are looking into? I always thought neutron detectors were for detection of nuclear activity.

Here are some neat neutrino facts:

  • Neutrinos are incredibly difficult to detect.
  • There are many neutrino sources, although supernovae may be the most prevalent with 99% of energy released as neutrinos vs 1% as visible light.
  • Our sun radiates about 2% of its energy as neutrinos.
  • They travel at the speed of light and rarely interact with normal matter. So rarely, in fact, that 99.99% of neutrinos would pass through a 10km-thick slab of lead.
  • Most neutrinos pass through the entire earth without hitting a thing.
  • 10^21^ nuetrinos pass through each 1" x 1" area of your body per second and, on average, you have a 25% lifetime chance of interaction with a neutrino particle.

Who knows what will be discovered!

That’s exciting!

RFK Jr announces that the environmental hazard causing autism is being hit by a neutrino while in the womb!

I can feel all those neutrinos on my body

Iirc there are some unsettled theoretical questions about the nature of reality and the cosmos that would possibly be answered by studying the behavior of neutrinos, but I forget what.

No sorry, I have to wait for the video. 😋

These are neutrino detectors, not neutron, so they won’t be looking for nuclear activity with it, right?

BussyCat@lemmy.world on 30 Aug 05:29 collapse

Nuclear reactions do involve neutrinos and antineutrinos but they aren’t super important for fission so I am assuming the decade long detector would be for something else

How to lock photons into their particle state and then manipulate them.

panda_abyss@lemmy.ca on 29 Aug 11:26 next collapse

Aren’t neutrinos very small? They might have a tough time looking for the giant ones.

Joking aside, it’s good to see progress like this, hopefully they share their findings openly.

That smile is going to be wiped right off your face when China actually finds a giant neutrino

panda_abyss@lemmy.ca on 29 Aug 14:28 next collapse

sigh time to rewrites the standard model of quantum physics again…

Isn’t giant neutrinos the thing that destroyed earth in 2012?

Trump turns off a completed wind farm while China completes decade long research platform. We are watching the seismic shift of technological progress from east to west in realtime.

Trump really has fucked everything up. America is falling.

this, like an open casket funeral, remains to be seen.

I’m already disappointed that it didn’t tear a hole in time space, not just destroying this reality but also making it so that it never existed and never can exist. A bit of a missed opportunity if I’m going to be honest. Maybe next time chums.

You mean a false vacuum collapse?

Soleos@lemmy.world on 30 Aug 16:56 collapse

Well it’s a lab in China, and neutrinos are small, like viruses. So clearly they’re developing a quantum virus to destabilize the west. Come December, we will see the first cases of the ominous QUOVID-25.

Congrats, you are now on a list, admittedly made by an idiot, but a list none the less.

Are they going to find out they’ve mutated again?

Whenever you hear that name, think about Chinese spies in big companies stealing secrets. A few other such places too.
