Question

why can't we see black holes?

Answer 1

Because it is present in the space so we can't see it

Answer 2

HELLO DEAR

HERE IS THE REASON WHY WE CANT SEE A BLACK HOLE  acually the images we see over the internet are  virtual and  made with   imaginations..

THE MAIN REASON why we cant see a black hole is that the escape velocity of a black hole is more than as compared to the speed of light i.e. 3 x 10^18m/sec

and hence the gravitational pull is very ,very strong and light can also not pass through it .  

so a black hole have probably   two main parts .. . the photons sphere and the event horizon  

HERE ARE THE EXPLAINATIONS WHICH MAY HELP U TO UNDERSTAND THE CONCEPT ...

PHOTON SPHERE : A photon sphere is a location where gravity is so strong that light can travel in circles. Photons orbit the black hole at the distance of the photon sphere. A photon could leave the back of your head, go once around the black hole, and be seen by your eye - you can see the back of your head. Isn't it sounds to be interesting :)

EVENT HORIZOZN : Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever cross the boundary and escape beyond it, including light. Thus, nothing that enters a black hole can get out or can be observed from outside the event horizon.

"HOPE U WILL UNDERSTAND THE CONCEPT " be brainly

plz mark it as brainliest :)
