Imagine a giant cube around the entire earth that touches in 6 places -- one on each cube face. Pick 3 faces and place a detector where each touches the earth -- on the surface. You can rotate the detectors around on the surface so that you get an arm in each axis relative to the center of the earth.
- magicalhippo 8y agoRight, that's basically what they do now by building multiple detector facilities. I was talking about multiple arms in a single location.
- jessriedel 8y agoThis isn't necessary since the wave looks the same at all locations on Earth.
- magicalhippo 8y agoIt can come directly from above, in which case you can't discriminate between from above or from below as it'll hit all arms at the same time if they're at a single location. You'd also have poor directionality.
- thewakalix 8y agoWouldn't the Spacetime Cube be just as vulnerable to the perpendicularity problem, though? It might have more sensitivity in near-perpendicular cases, but that's simply because there are more detectors.
- magicalhippo 8y agoAs mentioned, if multiple detectors are not spatially coinciding, then one can use the time difference between detection events as well.
