Black holes are usually shown as funnels. Is there one "funnel" pointing in a single direction or are there event horizons and "funnels" seen from every direction?
guywithdoubts said:There are no such funnels; what they are showing you in that classic image is that a black hole curves spacetime quite drastically, to the point of "infinity" (not to be taken literally however.) It simply attempts to show you in three dimensions what actually happens in four.
As for the question if they are black from all directions, the answer is, preliminarily, both yes and no. It depends on whether the black hole has angular momentum (and I *think* also charge) and if a singularity can, other than in theory, be effectively "naked" (ie. observable.) If you are thinking of the typical non-rotating black hole, then you'd see a black sphere - and of course a lot of gravitational lensing of the background around it.

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and its core collapses due to its own gravity.
A black hole is black from all directions because its gravitational pull is so strong that it even bends light, preventing it from escaping. This makes the black hole appear dark and invisible.
Yes, anything that comes within a certain distance from the black hole, known as the event horizon, will be pulled into it and cannot escape. This includes light and other forms of energy.
Black holes are detected indirectly by observing the effects of their strong gravitational pull on nearby objects. This can include the distortion of light from stars and gas, and the heating of surrounding material as it is pulled into the black hole.
No, black holes cannot be destroyed. They can only grow in size as they continue to consume matter and increase in mass. However, the Hawking radiation theory suggests that black holes can slowly evaporate over time, but this process would take an incredibly long time.
