Gravity Waves & Valentines

Valentine heart 120Scientists detected gravitational waves this past September, but spent the next four months checking their figures to make absolutely certain they knew what had happened and then, after giving it some thought, they chose to announce their findings this Feburary, just before Valentine’s Day. After all, these scientists are real flesh-and-blood people, not robots. They were as aware as you are that being swamped by love changes everything, affects your sense of time and space — alternately squeezing and stretching them  — as do gravity waves.

Linking gravity with Valentine’s Day gives a weight to the concept of love and meaningfulness to the notion of gravity. Gravity is powerful when objects are close to each other, but it weakens amazingly fast as the distance between them increases; in fact, it diminishes with the square of the distance and pretty soon it’s so weak as to be undetectable. Essentially, there’s nothing there. Phone calls don’t get returned, emails don’t get answered.

Scientists hoping to detect gravity waves searched for four years and got nowhere, no results. They shut down their equipment, improved it’s performance fourfold and began their search again. And they got lucky. Two intensely powerful gravitational loci circling each other closer and closer finally merged, devouring and sinking into each other in a fashion reminiscent of the poet Lucretius’s description of a man and a woman making love. The event, which happened 1.3 billion years ago sent waves across the universe which were picked up at the LIGO detector in Hannaford, Washington, and the LIGO detector in Livingston, Louisiana.

Those two points of pure gravitational energy were drawn to each other 1.3 billion years ago and the vibrations emanating from that mating have been traveling across the cosmos to us ever since, reaching us this past September, and expanding even now beyond us. It’s good to celebrate Valentine’s Day.

Tim Carmody, in his excellent piece, "How Haiti Became Poor", notes that President Trump's racist policies and vulgar language have sullied the word "shithole" which used to be one of the all-time great swear words. He's right. It's another terrible power this careless President wields.
