The trillions of neutrinos going through you are low energy neutrinos from the sun. We've been able to detect those for decades, and with only moderately pricey technology.
The neutrinos in the article are high energy ones produced from proton collisions at the LHC. Although we have ways of producing neutrino beams from accelerators, the LHC is not set up for that, and these neutrinos are sparsely produced, incidentally to the high energy hadron collisions being produced there.
In any case, the LHC cost at least an order of magnitude less than a trillion dollars. And the FASER experiment in particular which runs parasitically on existing LHC infrastructure runs on a shoestring budget, largely privately funded.
- Noobquestion 5y agoNoob qestion, but I am interested: um "So why the heck they doesn't 'fusion'-react their stuff in a hu liquid?", and why isn't there an energy-surplus gotten from 'friction' ? And yes, way back i read something about the (reversed) bernoulli-effect. Any help ?
- cshimmin 5y agoHmmm... in good faith I'm not able to parse your question. I don't know what hu liquid is, or what you mean by "their stuff". Maybe you could try again.
- magicalhippo 5y agoI had similar issues parsing the question. I've noticed a marked uptick in almost-but-not-quite comprehensible questions in the last few months in various internet venues, like Discord and Slack. Having run my own MegaHAL[1] on IRC back in the days, it made me think about if someone is having fun with a new generation AI chat bots... Not saying that is the case here though.
