U.S. astronomers have discovered a black hole in the middle of the spiral galaxy NGC 3147.
It appears as a thin disc. There is one thing that is puzzling researchers, technically it should not exist.
It is 130 million light-years from Earth.
The Hubble Space Telescope detected a thin disk of material rapidly whirling around the black hole.
This goes against Albert Einstein's theories of relativity.
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.
This supermassive black hole weighs approximately 250 million times more than the Sun.
