How One Memory Attaches to Another
A technical revolution provides insight into how the brain links memories, a process critical for understanding and organizing the world around us
Our memories depend on our ability to recall details about the world a child’s face, a goose, a lake. To transform them into actual experiences, though, the brain must somehow merge these individual elements into an integrated whole the look on that child’s face when she sees a flock of geese suddenly take flight from a lakeside stand of reeds.
Is Dark Matter Made of Black Holes?
A hidden population of black holes born less than one second after the big bang could solve the mystery of dark matter
More than a billion years ago two black holes in the distant universe spiraled around each other in a deathly dance until they merged. This spiraling collision was so violent that it shook the fabric of spacetime, sending perturbations gravitational waves rippling outward through the cosmos at the speed of light. In September 2015, after traveling more than a billion light-years, those ripples washed over our planet, registering as a “chirp” in the sensors of the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO).
