No. The nearest black holes to Earth are many light years away, much to far to affect us.
It is believed that quasars are most likely caused by supermassive black holes. Matter falling into the black hole would emit the radiation that has been observed.
The number of deaths in the famous mid-18th century incident at the black hole of Calcutta is a subject of dispute, figures seem to vary from low 40's to as many as 123 died.
a black hole is caused by a supernova, then the black hole forms. the matter sucked in and gets shot through a worm hole. after the wormhole the matter gets shot out a white hole. the wormhole is impossible to see, for witch this hard to belive for it goes from one end of the galixy to the other endhope i helped!
No one has "seen a black hole" but evidence of where a black hole must be has been observed.
No. Tomorrow has been and gone and no black hole has appeared.
No rubbish has been sent into a black hole.
Well, since nobody has ever been in a black hole....... what do you think?
Yes. Matter falls into black holes all the time; the first known black hole was the "Cygnus X1" black hole, which was discovered by the X-ray emissions caused by matter being pulled off the companion star and falling into the black hole.
Black holes do not create supernovae. Black holes are created from a supernovae.
No, if it had been sucked into a black hole, it wouldn't still be there shining in the night sky.
The black hole nearest to our Earth is (fortunately) several thousand light years away. No human has been farther from our Earth than our Moon. Thus, we are technologically quite a ways away from being able to travel to a black hole.
No one we know about
