The first-ever “photo” of a black hole. It’s an achievement once thought impossible, given that black holes exert such monstrous gravity that they swallow light itself.
Over the last century, science has shown that our universe is a far stranger place than our everyday experience would suggest. Space itself is curved and warped by mass. Time slows down on an object the faster it travels. Electrons act both as particles and waves. “Entangled’’ particles seem to instantly know and react to what happens to their partner across vast distances. At the quantum level, there is no empty space: Particles constantly pop in and out of existence, creating an ephemeral quantum “foam.” At the other end of the scale, there are least 2 trillion galaxies in the universe, each containing billions of stars and probably more than a few planets where intelligent life has evolved and is puzzling over the same questions as we are. The more we discover, the more it becomes clear that our certainties, whatever they may be, are built on illusions. We live in a great mystery.
