mar 12 2018· among other things its a significant step in confirming the origins of gold and other elements. the initial observation in august 2017 by ligo the usas laser interferometer gravitationalwave observatory was followed two seconds later by the detection of a short duration gammaray burst by the fermi space telescope satellite.
weiss himself came up with a design: build an lshaped interferometer and shine a light down the length of each arm at the end of which hangs a freefloating mirror. the lasers should bounce off the mirrors and head back along each arm arriving where they started at the exact same time.added that the event is not just a gold mine
