If we build enough of these things, can we combine the data and use them to take gravitational photographs?

- snek_case 5y agoThis is more like a microphone than a camera. I don't think you could really build a camera out of a large number of microphones, but you can detect events and infer their direction and distance with good precision.

- snek_case 5y agoThat requires bouncing sounds off of things though. With gravity waves I guess you would have to measure how objects deflect gravity waves produced by other sources. May be useful to try to measure properties about black holes or other invisible objects.
- rbanffy 5y agoYou use the detector as a camera and wait for a black hole merger to use it as a flash. Seems pretty doable with a number of detectors. The more the better the “photo”
