Nothing really, i am an Graduate student with a degree in electrical engineering. The negative terminals are only grounds, if a voltage is sent to a ground, nothing happens, the electric current just disperses into ground, which is normally a metal that has no voltage. The positive terminal connected to a the negative terminal on a battery has no voltage what so ever, so nothing will happen your fine, but you will not get any power though, that's the only thing that happens, if anything you might melt a fuse if it has one, but that's it.
I disagree, if you hooked both up backwards. You may have "popped" fuses, melted wires or even "fried" computers.
