Inside Japan's Big Physics | Part one: Super Kamiokande
Ғылым және технология
In the first of a new three part series, we go behind the scenes of Super Kamiokande, the world’s largest neutrino detector.
For more than half a century, Japan has been at the forefront of 'big physics', asking fundamental questions about the laws which govern the workings of the universe. Questions of this magnitude require cutting edge technology on a truly massive scale. Over three episodes, Nature reporter Davide Castelvecchi travels across to Japan to get a rare look inside three of its flagship experiments.

Thank you, Japan!

If neutrinos don’t interact with the EM force how do they produce light? Or is that just an analogy of what’s happening?
@Mehull458

Small probability to interact..As they have very little tiny masses

They emit a very faint shockwave or radiation which the photomultiplier picks up, the purpose of the water is to slow down the neutrino as it passes through and the purpose of the location inside the mountain is to ensure that there is total darkness,it is called ghost particle aside from being difficult to trace it can only be observed at night.

Antinutrino is same as Anti matter ???
@finnmurtonz7062
Жыл бұрын
Antimatter is just matter with same properties except charge, for example positron, is just an electron but positive. In the case of neutrinos, it's kinda difficult, because they don't have charge, so some say, antineutrinos are the same as neutrinos, i don't know how the difference them tho.

In 2001 one of the huge $3000 PMTs imploded under the pressure of the water column, generating a shock wave and setting off a chain reaction of implosions of adjacent PMTs that ended up destroying over 6,000 of the tubes in a massive cascade. oopsies

Would it not be better to somehow observe how neutrinos affect living matter...like our cell walls? Where do kids get their energy? You hear this all the time...maybe in passing through our cell walls they make the tiniest of vibration...like hitting a drum skin...the mitochondrial dna uses this to distribute energy to our body...or the light body...kids cell walls are bouncier that old people so transmit more useable vibration Nature is supremely unwasteful... Further...answer this how do we know 100% for sure that the search for new particles by smashing light into itself...how do we know that is not creating the super small sub atomic particles rather than them being pre existent withing what you have now broken
