Just a reminder, folks: we live in the future.

Physicists are excited by the discovery because it opens the door for telescopes that can “see” gravity.

At the press conference, Reitze said that the gravitational waves the scientists recorded from the colliding black holes “proves that binary black holes exist in the universe.” And that hasn’t been done before. “It’s the first time the universe has spoken to us through gravitational waves,” Reitze said. “We’re going to hear more of these things.”
