I had an idea relating to space time.
As this was not easy to explain, I started investigating what a Black Hole is.
There are many concepts about Black Holes. Often these are just former stars that are super condensed. Until recently one of the smallest ones known (because it was part of a binary system) is approximately 15 times the mass of the Sun
It might be interesting to find an orbit for this. Calculating with this mass, the orbit of something going at the speed would be 38 KM from the center (approximately 25 miles) It is possible that my calculations are not correct, but the idea of something in an orbit at the speed of light is not usually talked about.
Inside this orbit, light can not escape, but there are variations in the bending of light according to the distance.
This is not usually accepted in presentations, there is a lot of information, but a lack of knowledge.
