The Universe is not a static, stable place. Out of a vast collection of simple atoms, gas clouds collapse to form stars and planets, which then undergo their own individual life cycles. The most massive
Somewhere in space, two neutron stars slowly orbit one another. Their slow dance would have a cataclysmic ending. They were doomed to collide, to merge in a spectacular display of gravitational wave fireworks.
Fast radio bursts are one of astronomy’s tantalizing unsolved mysteries. These sudden pulses of radio waves come from far outside our galaxy. They last about a millisecond. And sometimes, the signals Until
Ripples in spacetime known as gravitational waves could reveal the answer to one of the greatest questions in the study of the Cosmos — why anti-matter in the early Universe did not completely annihilate
