There are three main types of black holes. The black hole's mass and size determine what kind it is.pic.twitter.com/Xt7wrjlHjz

#AskNASA Why do things swirl into black holes? Shouldn't they follow a (nearly) keplerian orbit? -
As long as you don't get too close to the BH's horizon, you can orbit it in a Kepler-like way. In fact, if you replaced our Sun with a black hole of the same mass, the Earth's orbit would be exactly the same! (answer via NASA's Bernard Kelly

Things only get weird if you're within a few horizon radii of the black hole. Then gravity's nonlinearity means there are no more stable orbits. - Bernard Kelly, Gravitational Astrophysics Laboratory

Not really about black holes but related - Why is spacetime represented as a 2-Dl "sheet" that can be bent by gravity instead of a 3-D cube-like form. All representations of space-time seem to show it as a sheet, like surface of a trampoline.
#AskNASA -
You're right - the 2D sheets are an analogy. We cheat and use the 3rd dimension to represent curvature, but if we could we'd use a 4th (space) dimension instead. If you can think of a good way to illustrate curvature in 3D, let us know! (via NASA's Bernard Kelly

If light is able to bend (or sucked) in the direction of gravitational pull, does light then lose its reflective and deflective characteristics in the confine of the black hole field force?
#AskNASA#BlackholeFriday -
All we know for sure is that light of any wavelength is unable to escape a black hole. The physics of what actually happens inside is unknown!

Possibly what’s known as “spaghettification”!

Hi,
#NASA I pray you and your family had a#blessed#Thanksgiving Question: When are you going to stop showing us#CGI or#GraphicArt because I can create that myself. I want posting#HubbleSpace#LiveFeed#FaceTime#LiveStories whatever... where I can see w/o#editing#askNASApic.twitter.com/eQ5ZTW7dMZThanks. Twitter will use this to make your timeline better. UndoUndo

I have my own theory that a black hole is something like an entrance to another place. Just zaps you somewhere else. Kind of like when you bend space/time and it folds, that's the fold point.
