- Gravitational pull and light speed ?
I have a question I have been wondering about lately ,somewhat abstract . Hopefully my description will be adequate . Here it is … The earth revolves around the sun because of the suns gravitational pull and earths inertia . It takes about 8 minutes for sunlight to reach the earth . What would happen if some cosmic force 'blinked' the sun out of existence .( the all powerful Q on Star trek made the sun disappear for some reason) Would the earth continue its rotation for the 8 minutes with the sun no longer there ,or (because the sun was instantly gone ) would the earth just continue in a straight line immediately ? Thanks for your responses
