The event was catastrophic on a cosmic scale — a merger of black holes that violently shook the surrounding fabric of space and time, and sent a blast of space-time vibrations known as gravitational waves rippling across the Universe at the speed of light.

 

But it was the kind of calamity that physicists on Earth had been waiting for. On 14 September, when those ripples swept across the freshly upgraded Laser Interferometer Gravitational-Wave Observatory (Advanced LIGO), they showed up as spikes in the readings from its two L-shaped detectors in Louisiana and Washington state. For the first time ever, scientists had recorded a gravitational-wave signal.

 

“There it was!” says LIGO team member Daniel Holz, an astrophysicist at the University of Chicago in Illinois. “And it was so strong, and so beautiful, in both detectors.” Although the shape of the signal looked familiar from the theory, Holz says, “it’s completely different when you see something in the data. It’s this transcendent moment”.

Vous ne connaissez peut-être pas le nom de Blek le rat alors que vous êtes familier de celui de Banksy. Pourtant, il est l’initiateur de l’art urbain et le premier à avoir introduit la méthode des pochoirs dans le graffiti. Le moins que l’on puisse dire lorsqu’on voit des images de ses réalisations, c’est qu’elles sont très proches de celles de Banksy. Et pour cause, ce dernier aura cette phrase à propos de l’artiste de rue français : « À chaque fois que je peins quelque chose je découvre que Blek le rat l’a déjà fait simplement 20 ans avant ! » Certains l’accusent même de parfois plagier Blek le Rat. Je ne sais pas si on peut vraiment avancer de tels propos mais il est clair que les deux ont de nombreux points communs. Au premier chef duquel, la contestation de certains..
