No, Gekko/Neo got it right... Think about this. If the sun were to suddenly dissapear, it would take around 8 minutes for us to see the effects (not see the sun)... Now some people thought that gravity had an 'instant' effect, hence people THOUGHT if the sun dissapeared, the earth would 'instantly' fly out of it's orbit because of no gravity. But some experiments have been performed to calculate it's speed, and scientists have found out that, within a 20% margin of error, that gravity does indeed have the same speed as light. And so if the sun dissapears, it would also take around 8 minutes for the Sun effect of gravity on the earth to totally dissapear, hence only after the 8 minutes are up, would the earth fly away.
