Scientists have finally measured gravitational waves from the collision of black holes. Marcia Bartusiak explains why this matters and talks about some of the universe’s most mysterious objects.
Marcia Bartusiak— Early last year, the field of astrophysics announced one of its biggest discoveries. A cosmic phenomenon that Albert Einstein had predicted a century earlier was at last detected directly. Two massive black holes collided, their spectacular merger generating huge ripples—gravitational waves—in the very fabric of space-time. After spreading
