![]() Most matter that passes by simply gets deflected a bit towards the black hole, and that's it. But the radius where this effect works is also rather small. And some matter that passes really close and looses enough momentum due to Bremsstrahlung (gravitational or electro-magnetical) or collision with other matter will become bound to the black hole, circle it while radiating away its energy, until it comes close enough to get sucked in. Matter that's on direct collision course will hit, of course. At the mass of the moon, the radius is on the order of $\fracmm$ sphere. The gravity field would be just the same as it is now. If the mass of the moon were concentrated in a black hole, you could draw a sphere around that black hole the size of the moon, and for everything outside that sphere, nothing would have changed. ![]() What do you think? If you could drop anything into a black hole, what would it be? Tell us in the comments below.It would suck in basically nothing. Would you still be totally screwed? YOU BETCHA! So if you happened to be near a supermassive black hole, you could cross the event horizon without really noticing. In fact, the larger the black hole, the weaker the tidal forces near its event horizon. For a solar mass black hole, the tidal forces near the event horizon can be quite large, but for a supermassive black hole they aren't very large at all. Unfortunately, this goes along with those who suspect black holes are actually some sort of portal. Many people think that it is at the event horizon where you would be ripped apart, and at the event horizon all sorts of strange things occur. The sky would simply appear more and more black until you reach the event horizon. What you would see is the darkness of the black hole fill your view and as you approached the event horizon you would see stars and galaxies on the edge of your view being gravitationally lensed by the black hole.

This effect of tidal stretching is sometimes boringly referred to as spaghettification. Eventually the tidal forces would become so strong that they would rip you apart. Because of the tidal forces it would feel as if you are being stretched head to toe, while your sides would feel like they are being pushed inward. ![]() These differences in forces are called tidal forces. As you got closer, your feet would feel a stronger force than your head, for example. Suppose you were falling feet first toward a black hole. Technically this is always true, but you wouldn't notice it… at least at first. As you get closer, the gravitational forces on various parts of your and your dragon's body would be different. But, as we've agreed, you're ignoring my advice and flying dragon first into this physics nightmare. The gravity of a black hole is just like the gravity of any other large mass, as long as you don't get too close. If you were falling toward a black hole, most of the time you would simply feel weightless, just as if you were playing Bowie songs and floating in a most peculiar way in the International Space Station. We know it won't take you to another world or galaxy, but what would you experience and see on your way to your inevitable demise? And what would the rest of the Universe see as this was happening, and would they point and say "eewwwwww"?
