Ripples never come back.
They do bounce or reflect however.
It is an interesting notion. Do gravitational waves bounce?
Light waves bounce. Neutrons, gamma rays, and radio waves bounce.
Why not gravitational waves.
And if you got a return (like from a radar ping) what would the return from a gravitational wave tell you about the object that it struck?
If you drink enough Ripple it will certainly come back up.
