But if watching matter tumble over the edge of a black hole might now be possible, it is only because of the efforts of a generation of astronomers 1 to wrestle 2 these dark dragons of the cosmos 3 into the realms of scientific reality.
As is often the case, it began with a series of observations that made no sense to anyone. A new generation of radio telescopes had come on stream on the 1950s that made it possible to see the universe in a completely different way. Almost immediately, they began to detect a series of strange, previously 4 unseen sources of light. Nothing had ever been seen like them.
These things looked very different, very strange, much more powerful, much larger, and really different than sorts of galaxies 5 and stars in our neighbourhood.
