A quotation from Dyson, Freeman

There is an enormous variety of things we’ve discovered that we never dreamed of, like, for example, black holes, pulsars, quasars, all these unbelievably active goings-on in the universe. Which in Aristotle’s time the universe, the sky, was supposed to be quiescent, it was supposed to be perfect and peaceful, and nothing ever happened in the celestial sphere; and that remained true, actually, throughout all of the revolutions. It remained the general view of astronomers right through Copernicus, and Galileo, and Newton, and everybody else, still, the universe looked very quiescent — until just the last thirty years, and now we know it’s not like that at all. In fact the universe is full of violent events, and fantastic, strong gravitational fields, and collapsed objects, and huge outpourings of energy. All these things were discovered in the last thirty years.
