the on switch keeps tripping
A spark gap is provided between the conductors and ground. Because it is a physical gap, it does not normally conduct. But when a large surge comes along, the voltage can break down the air in the spark gap and it conducts, shunting the surge to ground.
A black hole is an area gravitationally controlled by an object that has undergone total gravitational collapse. They are called black holes because their gravity is so powerful that not even light can escape. Worm holes on the other hand are theory only. For now most people consider them science fiction. They are proposed to exist as a result of a black hole, sort of like a cosmic gravitational whirlwind created be the immense gravity of a black hole. Some believe that if wormholes do exist, they could be portals to other places in the universe, or to other universes. We do have strong evidence that black holes exist, but there is not yet any evidence at all of worm holes.
Buck Wheat say's a black hole is in space and a worm hole is in your apple !! oooohhh taaaa !!
