Technically, we can't see the black hole itself - just the results of it. And we know that only a black hole could be doing what we see happening. Like causing enourmous amounts of gas to spiral in onto it, as the now superheated gas emits x-rays.

Black holes do not emit radiation, including visible light. You can't see the actual black hole itself. However, what you would see is a black sphere that is the event horizon (beyond this point, the gravity is so strong that the escape velocity is greater than the speed of light). Around this black sphere is a disk of gas and other matter. The gas is glowing brightly, particularly in the X-ray wavelengths. So, basically, imagine a completely black sphere surrounded by a flat gaseous disk.

I think of them as distortions in space and time. I also think that a massive amount of density in a small area is part of what creates some of the effects that black holes have on their surrounding areas. Even light cannot escape the gravitational pull of them so most likely any models of their appearance have resulted from advanced equations. As far as their shape I believe that they resemble an hour glass. You can find gobs of info at NASA related sites. Check out spaghetti theory I think it talks about the intense compressing forces of the black holes. Makes for neat reading.

They don't look like anything. In order to see, light has to bounce off something and go into your eye. But black holes have such a strong gravitational pull, that light just gets sucked into them and isn't able to bounce back and escape. If you were to look towards one from a distance it would literally look like a big black hole in the middle of space. Because no light would reach your eye from anywhere past it's event horizon which is a mathematical circle around the black hole that indicated the boarder where light can no longer escape.

They look like a black sphere. If the hole is near to any matter, then the matter will usually form a disk in orbit aroiund the hole, and the matter closest to the hole will gradually fall into the hole, being ripped apart as it goes, and giving off extremely bright like, so althought the hole is dark, the matter around it can glow brightly. Think of a giant glowing whirlpool in space. The matter that goes in is gone for good.

They're absolutely invisible because light itself is trapped by their intense gravity. They can sometimes be detected by their effects on surrounding matter, however, for example if it is swallowing a nearby star the result of that star's mass accelerating into the black hole will be the emission of high-energy x-rays.

Black holes are invisible, because light can not escape from them. We know that an object can be seen for two reasons. 1) It has its own light (like sun, lamp)2) It reflects the light (like stones,papers,flowers and ,,,,)
Because light can not reflect from a black hole, scientists can not see it. However there is indirect evidence that black holes exist.

Tall, Dark, and Handsome.
It's more what you don't see. Around them you see stars. Where you should see stars you see nothing.
The cool thing about black holes is that you can take a picture of them and it doesn't matter if you take it in black and white or color, because they look the same.

No light, just a point of darkness.
They inherently cannot look like anything. Why do you think they are called BLACK holes?
Stupid question = stupid answer.

You can't see black holes, they're virtually invisible to the naked eye and cameras.
