Speed of Gravity Measured for First Time
Taking advantage of a rare cosmic alignment, scientists have made the first
measurement of the speed at which the force of gravity propagates, giving a
numerical value to one of the last unmeasured fundamental constants of
physics.
"Newton thought that gravity's force was instantaneous. Einstein assumed that
it moved at the speed of light, but until now, no one had |
