hey, its like 2 in the morning, can't sleep, and i've always said I do my best thinking in the bathroom.   alright here's my idea, you know how in those high-school videos on basics of the universe show the universe on like a graph, usualy when they talk about weight an how gravity works like a sheet with heavy globes on it puting presure on the sheet. well i was thinking how einstein said nothing could move faster than light, and that every action has an equal and oposite reaction. i think if you could get up past light speed you would drag space with you like draging air with you in a car, and if you kept pulling with a lot of acceleration, you could conceivably tear a hole,
a black hole, that so far seems pretty simple by my gueswork but heres the twist, what if you took this thing accelerated in an instant past the speed of light and dragged the space with you close to the tearing point and killed the engine? i think there could be a slingshot effect as space drags itself in alignment sending the thing hurling at great speeds in the opposite direction,(like pulling back on a slingshot and letting loose, but in this case its space for a ruber band)  this idea is based on einsteins theory that every action has an equal and oposite reaction, plus my assumption tha the universe is elastic rather than rigid, (sadly uneducated)  
i hope i explained my idea well, or if this is an idea thats already been thought up i'm sorry, like i said im uneducated with only a high school diploma, i tend to philosiphises a lot when i dont sleep.
