2. Interesting question

I have seen that first illustration in several places when discussing wormholes. The problem I see is this: how do we fold space in half? Sure, it looks like an elegant solution to long distance space travel, but honestly, we can't even get humans to Mars. What makes us think we will ever figure out how to fold spacetime?
