Ooguri is funny. He says Hermann Nicolai exposed his secret spin foam past.
That's why I am asking ;-)lfighter said:You don't know what Witten is interested in and why.
I've looked about but I don't see that LIGO or any other experiment has reported discovery of gravitational waves so I assume that Witten is simply suggesting they will surely be discovered but I'm not sure.Gravitational waves seemed hopelessly undetectable when Einstein first proposed - predicted them and the fact that eventually an incredibly story involving the binary pulsar made it possible to discover them was totally unforeseeable.

Have gravitational waves been observed or am I reading too much into Witten's statement?
