Frontiers of Astronomy: A Space-time Symphony of Gravitational Waves

On February 11, 2016, scientists announced the first detection of gravitational waves, a Nobel Prize-level achievement and a profound moment for humankind. Prior to that discovery, the only way we learned about the distant Universe is through light we were able to see. And now, humanity has observed the ripples in space-time caused by the motion of massive objects like black holes; these gravitational waves have opened a whole new window to the Universe of things we can't see with light—things that could change our understanding of the Cosmos
