Image of a black hole

Depends on the mass of the black hole and it is defined by Schwarzschild radius.

 

And you would expect this to increase over time. As it keeps attracting more light and matter.

It is only radio as this is beyond infrared.

Yes

It increases as long as there is matter that moves in the direction of the event horizon. It is not a magnet to attract things.

Yes, of course not. I am just wondering, given that it takes up matter, if the gravitational field increases over time, making the radius bigger.

I still don't understand how they can image a black hole using light, when black hole should have enough gravity to bend a beam to light. Is it the diffracted light they are imaging? It obviously is more blurry if it is diffracted light instead of reflected light. 

That light is arund the even horizon. Not directly from black hole.If you got time watch this . This is very closely how Kip Thorne came up mathematically for Interstellar movie.

Maybe that's why, the image is blurry. At each point, the light wave is refracted. So the topography is not very accurate. Maybe it's not a circle with a hole? Maybe the dimensions are different. 

Image is blurry because ..the actual image of around a pea size and they had to make it bigger public consumption ani ekkado read.
