Its implications made him uneasy  — that every particle has an antiparticle, and that perhaps the whole […]

Imagine a massive bell ringing somewhere across the cosmos — except the bell is two black holes crashing into each other, and the ringing is not sound, but ripples in space itself. These ripples, called gravitational waves, stretch and squeeze the very fabric of the universe.  Predicted by Albert Einstein in 1916 as a consequence […]
