B If space is transparent how can we not view light from a black hole

AI Thread Summary
Black holes do not emit or reflect light, making them invisible to direct observation. Although space is transparent, black holes capture light with their gravity, preventing any light from escaping. As a result, there is no light available for us to see, leading to the conclusion that we cannot visually perceive black holes. The discussion emphasizes the physiological understanding of "seeing" in relation to light emission. Ultimately, the question of visibility regarding black holes is resolved by the absence of emitted light.

They do not emit or reflect light, so there is nothing to see.

Space is transparent so they do not have to reflect light they capture light with gravity so we should be able to see them
 
This thread will be closed to give the OP the opportunity to learn what "see" physiologically means.

There is no light which is emitted by a black hole. We cannot see what is not there. Question answered.

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
