Another instrument used to calculate and measure what is going on in deep space is LIGO (laser interferometer gravitational wave observatory) a very high-tech sensitive detector. One has been built here in Louisiana another twin ligo facility in Washington State and a 3rd LIGO type called VIRGO in Pisa, Italy. Soon there will be a triangulational experiment between all 3 facilities in an effort to prove Einstien's theory of relativity using deep space gravity wave info. Recently 3 new theories have been proposed as possibilities to unify quantum theory, cosmology and relativity by dr Lee Smolin a professor ofv physics at the Center for Gravitational Physics and Geometry at Pennsylvania State University. The LIGO project is a callaberation between The National Science Foundation, Caltech and MIT.
