I liked my first pin hole camera.
It was a piece of cardboard with a pin sized hole in it.
I constructed a box with wax paper on one side, the cardboard with the pin hole on the other side.
As I panned the box around the backyard, I could see its image upside down and inverted on the wax paper. I was amazed about the amount of information carried by light through such a small hole.
I could see the back yard through it!
Black Holes 125 million light years away.
They bend light towards their center, however, some light must escape.
I would think some light might even do a U-Turn around the black hole.
If that is found to be true, a very powerful telescope should be able to view our sun's light from 250 million years in the past. It would offer us a reflection from the past, and it would eliminate our need to travel faster than the speed of light, to look back into Earths past.
Who knows for sure. Maybe the Hubble has already discovered this to be true. hmmm.
