Okay My Science teacher told me that our telescopes cannot physically see Black Holes. Okay then so I started watching Discovery Channel, then they
said that we detect Black Holes by measuring magnetic things etc. (I DONT REMEMBER). How exactly do we do this if we can't go near the Black
i am not a pro but can remember stuff like it it is near a star you can see the trail of light from the star to a swirl also i think you use
something like radiation micro gamma rays or something like that.
I'm not at all a specialist with this type of stuff but I recall hearing about a certain kind of radio wave or something of the sort, that right
before it reaches the event horizon of a black hole releases radio waves/micro waves/x-rays and then the event horizon absorbs it. But the signals it
sent out right before reaching the event horizon can be detected. Sorry, that's the best input I can give on this one.
Black holes have massive gravitational fields, and they affect the things around them, like stars. Sometimes a black hole is found near a star, and
the black hole's gravity starts pulling matter off of the star, and the stream of matter can be seen entering the black hole. Also, in some solar
systems, there are what are called binary star systems, and sometimes one of those stars is instead a black hole. So, they can basically see this
star orbiting something invisible.
