I haven´t been posting much for a while .. so I don´t know if you had this one already ........
One of Einsteins last enigmas from his theory of relativity from 1916, is the prediction of gravitational waves .... causing vibrations of spacetime ...
So far they have eluded earth based detectors .... AURIGA and LIGO ...
But in ... ahemm ..... 2018 LISA might find them ......... it´s 3 spacecrafts will be placed in a triangle with 5 millions km distance .... and the lasers can measure variations in distance between the spacecrafts of 10 picometers ...
less than the size of one atom !!! ......... theoretically .... hmmm....hmmm ..
