Also, this applies only to circular orbits, and does not indicate that a powered ship could not maintain orbit.

- dvdkhlng 11y agoBTW most of what I know about black hole physics is from Greg Egan's novel "Incandescence". Which covers quite a lot of science for a work of fiction (and overall extremely inspiring). http://gregegan.customer.netspace.net.au/INCANDESCENCE/Incandescence.html http://gregegan.customer.netspace.net.au/INCANDESCENCE/Incan...
