“It is official today that the whole of our solar system is moving, insensibly, towards the celestial point marked by the sixth star of the constellation of Hercules (or Zeta Herculis, according to our language). This igneous abyss—of dimensions such that the numbers which express it would somewhat confuse thought (if, for those who think, the apparent sky could have any importance)—seems, in astronomy, to be the end or the inevitable erasure, in fact, of our set of phenomena.”

Auguste Villiers de L'Isle-Adam, 1890
