I'm but a dumb computer developer but I have often wondered if it possible (not now but way into the future) to make a telescope like detector based on neutrinos. Although you still have the resolution problem I think neutrinos are affected by different things than photons (ie ambient light should not be a problem). I know there are neutrino detectors but none of them show the shape of galaxies (I think).
- jjoonathan 11y agoLike the IceCube? Or do you mean low-energy neutrinos specifically? https://icecube.wisc.edu/ https://icecube.wisc.edu/
- pif 11y agoThe fundamental question is: if neutrinos provide a better signal because they overall interact much less than photons (a visible photon coming from the farthest corner of the universe will stop running as soon as it meets my eye; a neutrino can cross a star without noticing), how will you get them to interact with your telescope? That's a big problem for direction detection, too: with a telescope, it's easy to determine which direction the light comes from, as it can cross the front glass but not the surrounding casing. When a neutrino (out of several billions crossing your detector) finally gives a signal, you can't even know whether it's coming from the sky or out of the Earth!
- monocasa 11y agoTo get better than a completely blurred image, you'd need some way to focus the neutrinos. That's where the fact that photons are affected by more things work in their favor for this use case.
