In Einstein’s manuscript 1916 :”Two celestial bodies in orbit will generate invisible ripples in spacetime”.
Science must be correct, ‘ two celestial bodies in orbit’ is easy to understand and clear, can not be assuming as two black hole collide or merger. There are difference between the impact of ‘in orbit’ and collide or ‘merger’. Moreover, we know Einstein didn’t believe in black hole. Einstein is The Reluctant Father of Black Hole. He never predicts ripples in spacetime or gravitational wave in connection with black hole.
LIGO’s gravitational waves nothing to do with Einstein.
LIGO’s experiment has not verified the Einstein’s theory of gravity.
Two celestial bodies in orbit will generate invisible ripples in space time yet to be proven.
