The Gravitational Waves Of Uncle Albert

Somewhere out in the far reaches of space, 1.3 billion light years from Earth, two incredibly dense black holes spin around each other, racing at incredible speeds and moving ever closer to their inevitable collision.  Finally, their event horizons merge, and they become one.

At the moment of contact, the black holes lose mass and emit gravitational waves — bursts of pure energy so powerful that they warp space time.  It sounds like a fantastic, far-fetched scenario, but it’s not.  This week, scientists announced that they were able to detect, and record, the gravitational waves here on Earth, on special antennae.  You can listen to the chirp-like sound of the gravitational waves through a link here.

Gravitational waves, the bending and stretching of space time, the changes in relative time as a traveler approached the speed of light — all of these, and more, were born in the fertile brain of Uncle Albert.  This week we learned, yet again, that the story of Albert Einstein is one of the great stories in the history of the human species, and it reaffirms that one person, through hard work and brilliant insight, can make all the difference.
