Wani Wrote:What do you mean "bigger the hole, less force"? o_o And as for the rest, yes, that's exactly my point. If you stay outside the event horizon, yes, you theoretically can escape, but if it's a decently sized black hole (As in, not one made by the LHC), if you're too close, chances are, you're dead anyway.
The force needed to stay stationary outside of a Black Hole's Horizon decreases with the mass.
"Your calculations show that the larger the hole, the weaker the rocket blast you will need to support yourself, hovering at 1.0001 horizon circumferences."
~ pg 40 of Black Holes and Time Warps by Kip S. Thorne.
I can't find the equation on the Wiki page, but it's something like how much the hole bends space. An increase in mass decreased the bend. :>
Imagine a Bowling Ball on a mattress. It bends in. Now imagine a led ball weighing less than the ball, but having a much smaller diameter. It'll make a steeper dip in the mattress. The same applies to Black Holes, if I remember correctly.
