We have recently managed to feel how space and time vibrate. Two black holes, in a dizzying dance until they merged into one, convulsed the structure of space and time around them with almost unimaginable violence, emitting strange music from a distant darkness. The detection of gravitational waves - the most common way of referring to this finding - culminates the revolution that began a century ago in our ideas about gravity, space and time, and the structure of the Universe. But it also opens up a new way of conceiving the cosmos for humanity. In the same way that the transition from silent to sound cinema uncovered previously impossible forms of expression, the wealth of qualities with which the Universe now manifests itself to us will change our way of imagining it.
