Wow!! This is cool ! We r so near to have a view in to "fabric or reality "
Ripples in spacetime, a bit like ripples on a pond, that propagate out at the speed of light. Throw something really big into the stillness of space – like two black holes colliding, or two pulsars merging – and gravitational waves created by the event should spread not just across the galaxy, but ultimately through all of spacetime. #science #space #time
