Massive U.S. Machines That Hunt For Ripples In Space-Time Just Got An Upgrade
"Scientists are about to restart the two giant facilities in the United States that
register gravitational waves, the ripples in the very fabric of the universe that were predicted by Albert Einstein more than a century ago."
"Einstein realized that when massive objects such as black holes collide, the impact sends shock waves through space-time that are like the ripples in water created by tossing a pebble in a pond."
"In 2015, researchers made history by detecting gravitational waves from colliding black holes for the first time — and this was such a milestone that three U.S. physicists almost immediately won the Nobel Prize for their work on the project."
