À propos de cet audio
This is your Astronomy Tonight podcast.
Good evening, stargazers! On this date—February 11th—we're celebrating one of the most breathtaking discoveries in modern astronomy: the detection of gravitational waves from colliding neutron stars!
On February 11th, 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced the first-ever direct detection of gravitational waves. Now, I know what you're thinking—"gravitational waves? Aren't those just theoretical?" Well, they were! Until that magnificent moment when two neutron stars, remnants of massive stars that had long since gone supernova, spiraled into each other roughly 1.3 billion light-years away, creating ripples in the very fabric of spacetime itself.
Einstein predicted these waves way back in 1916, but nobody could actually *see* them—or rather, detect them—for a century! That's right, a full hundred years of theoretical physics patiently waiting for technology to catch up. And when those gravitational waves finally washed over Earth on September 14th, 2015 (though announced on this date), they were so minuscule that LIGO had to measure movements a thousand times smaller than a proton. Absolutely mind-boggling!
This discovery opened an entirely new window on the universe—literally a new way to observe the cosmos without using light at all. It was revolutionary, paradigm-shifting, and absolutely worth every penny of the billions invested in this incredible experiment.
