“They can tell us about deep space in ways we can’t learn otherwise,” says particle physicist Jamie Boyd of CERN. “These very high-energy neutrinos in the LHC are important for understanding really exciting observations in particle astrophysics.”
Can anyone who knows more about this subject elaborate? What are they expecting to learn, or do we not have an idea yet? Like what different things could we learn from this that we aren’t learning from other possible colliders or deep space telescopes like James Webb?
Nuetrinos get generated at center of stars and supernova. So if we can detect them directly we can peer into the middle of the sun or other crazy things we’d never be able to see before
Light hits matter, causing it to get blocked. This is super convenient for seeing things, but super inconvenient for seeing through things.
The early universe was super dense and light couldn't escape it. However, at some point it got cool and sparse enough that nutrinos could. If we could detect those nutrinos from the early universe we could learn things about what the universe was like in the early part of the big bang.

The CNB (Cosmic Neutrino Background), not to be confused with the CMB (Cosmic Microwave Background), composed of photons and which you mention in another reply further down this thread.
As neutrinos were able to liberate themselves in a straight line from the post-Big Bang pinball soup earlier than photons, the CNB would let us peek further back in time.
The holy grail would be the Cosmic Gravitational Background, basically the fading “GONNNNNG…!” of spacetime ripples created at the Big Bang itself, as if it was a bell that was struck.
This summer the detection of low-frequency gravitational waves was announced, and while that’s about “a” gravitational background, it’s not “THE” Gravitational Background, by which I mean not the one from the Big Bang itself.

Could it also help us determine a more accurate age of the universe?

If you’re immediately getting down voted for a relatively innocuous post, it could be you’ve irritated someone with a few bots.

Light gets blocked by matter. Neutrinos are hardly affected by it.
