I came across this website which basically contradicts most of what I've heard about a black hole.
http://www.engr.newpaltz.edu/~biswast/bhole/blackhole.shtml
In particular, it claims that it's possible to escape a black hole by reversing one's momentum after crossing the event horizon.
Is that right? It seems reasonable if we treat mechanics as time-reversible; yet, almost everyone says that nothing can escape a black hole. If nothing can escape a black hole, what is the time reverse of an object free-falling into a black hole?
