Gravitational Waves Detected
Just over 100 years since publishing his General Theory of Relativity in 1915, Albert Einstein has been found correct once again. Perhaps, like myself, he’s tired of being right all the time? We’ll never know.
But with the discovery of gravitational waves, from two colliding black holes over 1 billion light years away, E=mc2 is still the reigning champ of theories known worldwide.
But now that we’re convinced we’ve uncovered proof will it become Einstein’s “fact” of general relativity?
A team of scientists within the cooperative LIGO, Laser Interferometer Gravitational-Wave Observatory, noticed a faint chirp in September of 2015. LIGO is comprised of two locations, one in Louisiana and the other in Washington, at a cost of over $1.1 Billion over 40 years!
However, the chirp wasn’t announced to the world or press until February 11, 2016, after months of fact-checking and mathematical equations to ensure accuracy.
There could be long-ranging effects from this discovery, including a new way to observe the heavens for astronomers. It could also introduce a new realm of physics.
What I’m curious about is, “How do they know it’s from two colliding black holes over a billion light years away?” I’ve read many stories on this discovery but yet, no mention of how they know the source. I wonder when they’ll let us in on this little secret.
Time – and maybe even space – will tell.
That faint rising tone, physicists say, is the first direct evidence of gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago. (Listen to it here.)
