I have read this:
https://en.wikipedia.org/wiki/Neutrino
The weak force has a very short range, gravity is extremely weak on the subatomic scale, and neutrinos, as leptons, do not participate in the strong interaction. Thus, neutrinos typically pass through normal matter unimpeded and undetected.
Now we know that from black holes even light cannot escape.
And neutrinos should have rest mass. But neutrinos are not affected by gravity on the subatomic scale, because gravity is very weak on that scale, and neutrinos interact very weakly.
The only reason even light cannot escape a black hole is gravity (stress energy) that bends spacetime. But since neutrinos are not affected by it on the subatomic scale, neutrinos should pass through a black hole.
Question:
- Do neutrinos pass through black holes like through normal matter? Has there been any experiment to measure whether we can detect neutrinos that passed through black holes?
Best Answer
No, you have a wrong understanding of the Wikipedia statement. Wikipedia says only "Gravity is extremely weak" on a subatomic scale. It does not say "neutrinos are not affected by gravity".
They cannot pass through a black hole just as light cannot pass through a black hole. Photons are even lighter (no mass is as light as can be!) than neutrinos, and photons are certainly at "subatomic scales" (they are fundamental particles!) and so if photons cannot escape black holes, neutrinos can't either. (In fact nothing can - that's why they are black holes.)
