In a landmark discovery for physics and astronomy, scientists said Thursday they have glimpsed the first direct evidence of gravitational waves, ripples in the fabric of space-time that Albert Einstein predicted a century ago. When two black holes collided some 1.3 billion years ago, the joining of those two great masses sent forth a wobble that hurtled through space and reached Earth on September 14, 2015, when it was picked up by sophisticated instruments, researchers announced. "Up until now we have been deaf to gravitational waves, but today, we are able to hear them," said David Reitze, executive director of the LIGO Laboratory, at a packed press conference in the US capital.
CLEVELAND (AP) — The mayor of Cleveland apologized Thursday to the family of Tamir Rice, a black 12-year-old boy fatally shot by a white Cleveland police officer, for the city having sent the administrator of the boy's estate a "decedent's last dying expense" claim of $500 for ambulance services.
