Gravitational waves detectors, just like any kind of antennas have anisotropic sensitivity. By having multiple detectors with different orientations you can determine the source of the signal. But you can't aim them, no, at least not any current or planned ones. They are simply too big (many kilometers) and require extreme stiffness.
Everybody knows of LIGO, but it's actually three detectors that work together, LIGO, Virgo, and KAGRA.
- _Microft 2y agoThere is also a project called GEO600 in Germany that is collaborating with LIGO (and therefore also Virgo/KAGRA). This detector is much smaller though. https://en.m.wikipedia.org/wiki/GEO600 https://en.m.wikipedia.org/wiki/GEO600
- BurningFrog 2y agoYou can also figure out the source direction by when the signal arrives at the different (currently three, on a good day) detectors.
