Learn how a "black hole 30 billion times the mass of the sun in a galaxy 2 billion light years away" using gravitational ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

Because it doesn't interreact with light or electromagnetism, dark matter exists to us only through its influence on visible ...
