How can we see black holes when it does not even allow the light particles escape through it
Answers
Good question...
➡️Black holes cannot be seen....Why?
If we want to see a object, light should fall on its surface and it should reflect back to our eyes.
So...black holes won't reflect light...Bcz it captures all light...
➡️Then how we know that there is black hole?
Black holes are predicted using complex mathematical calculations and physical analysis of the Gravitational waves...
As u know Black holes have infinite density, it's escape velocity is equal approximately equal to 300000000 m/s
While that of Earth is 11000m/s
So it got much density and unimaginable gravitational force...
➡️Easily explain Black hole?
Suppose u know that a star like our sun is more than 1000 times larger and heavier than our mother planet Earth...
If a star like Sun is compressed to a football like structure (keeping matter and weight same) it will have density tending to infinity...
So the gravitational force will be extremely high(actually gravity acts like a stretched rubber sheet... Heavier the particle u put I btw, all surrounding bodies will move towards it)..
So black holes are having infinity gravitational power and density so that even light can't escape
