Neutrino detectors are essential in receiving communication from other galaxies.

That doesn't make any sense. Photons would work much better.

Photons work better for driving a car too but being able to hear is still quite useful.

In other words: we already have lots of things that measure photons. You see things on two totally different media it's a lot more compelling than just one.

		That may be the case, but it doesn't explain why neutrinos would be essential for intergalactic communication. Maybe the person I was responding to didn't realize neutrinos travel very close to the speed of light, not infinitely fast?
