Atom Interferometers and other sensors for arrays to replace-complement LIGO.

Yijun Jiang,  Thank you, this comes at a good time. I was reviewing all the technologies that can replace LIGO with atom interferometer and other technologies. Some of them are not very mature yet or the groups have not put in a lot of effort to look at black holes. But there are lots of sources on earth and in the solar system that can be used for increasing levels of sensitivity. When the MHz and GHz and higher frequency gravitational detectors come online, they can start monitoring the interior of the sun and other local bodies. But I expect massive black hole interiors will be next. There is every reason to expect those are not singularities. Not compact.
