Warped Space and Time Around Colliding Black Holes
This computer simulation shows the warping of space and time around two colliding black holes observed by LIGO on September 14, 2015. LIGO detected gravitational waves generated by this black hole merger—humanity's first contact with gravitational waves and black-hole collisions. Gravitational waves are ripples in the shape of space and flow of time.
The colored surface is the space of our universe, as viewed from a hypothetical, flat, highe
