In a new study, two University of Chicago astrophysicists laid out a method for how to use pairs of colliding black holes to measure how fast our universe …

Black holes don’t just swallow matter. They also spit it out. From their polar regions, they can launch massive jets of energetic plasma that travel at nearly the speed of light, stretch longer than our galaxy and last for many millions of years. Scientists who are part of the Event Horizon Telescope (EHT) project have announced they’ve imaged the magnetic …
