understanding quantum physics is an incredibly important endeavor IMO.
new dimensions
time travel
teleportation
conversion of mass to energy and energy to mass
designer atoms with totally new properties
sure, I read a lot of comic books but I know just enough about physics to know the potential applications are vast
oh, and a black hole with almost no mass in it has almost no gravitational pull, I think.....so that means if they create one it will fizzle out safely contained.
