Hi - I have a question about wormholes, specifically when the two endpoints have a differnt gravitional potential. If we imagine the technology extisted to create a person sized wormhole between say the earth and the moon, I think the popular perception would be that one could simply walk through the wormhole on earth and walk out on the moon. However there is clearly a big difference in gravitational potential energy between the earth and the moon. A rocket leaving the earth has to expend alot of energy climbing out of the earth's gravitational well, and not much breaking against the moon's gravity when it lands. If the wormhole is say one meter long, this difference in potential occurs over the space of meter instead of the 200,000 miles or so of ordinary space. So I would expect their to be massive gradient inside the wormole, which would require a massive force to get something through. Converly if one pushed an object from the earth to the moon it would experience a huge force pushing it down to the earth and presumably smash to bits. Is this roughly correct?
