We have learned that the centre of the milky way contains a very massive black hole. We developed this 
understanding by: - Monitoring the orbital motions of many individual stars in the very central parts 
of the Milky Way 
If the sun were to be squashed down small enough to become a black hole, then: - The planets in the 
solar system would orbit the Sun in unchanged fashion (but would receive no light from it)
