What if you could follow your own gravity field and travel millions of miles?
Scientists at the Ligo Collaboration project have twice detected gravitational waves from the interstellar collision of two black holes, confirming Einstein’s predictions about gravitational waves.
“It seems we’ve officially entered the age of gravitational wave astronomy,” wrote Gizmodo.
The project’s executive director explained: “It’s the first time the Universe has spoken to us through gravitational waves. Up until now, we’ve been deaf.”
Over at the Washington Post, one writer explained how Einstein predicted these cosmic constants: “A planet will orbit a star not because it is connected to the star by some kind of invisible tether, but because the space is warped around the star.”
In an online essay, writer Gabriel Harper pondered the mystery of our personal gravitational fields, trying to measure how we personally produce ripples in space.
He explained a mind-bending concept: how your personal gravitational field grows over your lifetime and spreads into space.
“Our gravity field weakens over distance, but never reaches zero,” he explained. In the essay, he calculated the stunning distances that your gravitational field travels during your lifetime:
By the time we’re 30 years old, our gravitational field extends some 300 trillion miles around us into space. Still feel small? But the really crazy part is that when we die, our gravity will continue to exist forever, infinitely stretching out into the universe, passing through Andromeda millions of years from now, and beyond. Everyone you have ever known, alive or not, is traveling right now through the depths of space.
Harper concluded his meditation on gravity with some inspiring speculation:
The gravity of our most distant ancestors, and everyone that has ever existed in the history of the world, faithfully hurtling out into the universe, eternally diminishing into nothingness but never truly disappearing. Like a glass of water that you pour, and pour, and pour but it still always has just one drop left to give. I’d like to think when we go, our souls might hitch a ride on that wave of gravity and we can all spend eternity cruising the cosmos together.
