Chrome: If you've ever wanted to see what people are saying about a web page you're visiting beyond the site's own comments, Chrome extension Twitter Reactions will show you the most recent tweets that are talking about the page.

The idea isn't unlike other universal commenting systems, like Google Sidewiki—but instead of just seeing the comments of Google Toolbar users, you can see what the entire Twitterverse is saying about the page that you're on. It takes a bit of filtering with all the retweets or simple linking going on on Twitter, but it's definitely interesting to see what people are saying beyond the site's integrated comments and who's linking to it—especially if it's your own site or blog (you might be surprised how many people have linked to you on Twitter!).

Twitter Reactions is a free download, works wherever Google Chrome does (Note that you need to be on the beta channel for Linux or the dev channel on OS X for extension support). Thanks, Chris!

Go get your protective tin foil hat, because you’re going to need it. German scientists have been trying to understand why their equipment that measures gravitational waves has been picking up a particular sound. One possible answer that they’ve come up with is that the entire universe is a holographic illusion:

For many months, the GEO600 team-members had been scratching their heads over inexplicable noise that is plaguing their giant detector. Then, out of the blue, a researcher approached them with an explanation. In fact, he had even predicted the noise before he knew they were detecting it. According to Craig Hogan, a physicist at the Fermilab particle physics lab in Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of space-time – the point where space-time stops behaving like the smooth continuum Einstein described and instead dissolves into “grains”, just as a newspaper photograph dissolves into dots as you zoom in. “It looks like GEO600 is being buffeted by the microscopic quantum convulsions of space-time,” says Hogan.

If this doesn’t blow your socks off, then Hogan, who has just been appointed director of Fermilab’s Center for Particle Astrophysics, has an even bigger shock in store: “If the GEO600 result is what I suspect it is, then we are all living in a giant cosmic hologram.”

The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level.

The holograms you find on credit cards and banknotes are etched on two-dimensional plastic films. When light bounces off them, it recreates the appearance of a 3D image. In the 1990s physicists Leonard Susskind and Nobel prizewinner Gerard ‘t Hooft suggested that the same principle might apply to the universe as a whole. Our everyday experience might itself be a holographic projection of physical processes that take place on a distant, 2D surface.

Here’s a study that will surely pour more gasoline into the debate of dog vs cat: turns out that cat owners are more likely to have college degrees than dog owners.

A poll of 2,524 households found that 47.2% of those with a cat had at least one person educated to degree level, compared with 38.4% of homes with dogs.

The study said longer hours, possibly associated with better qualified jobs, may make owning a dog impractical.

Believe what you will, but the study authors made one big error: cats don’t have owners. They have staff

La suerte quiso ayer que la periodista Yolanda Sacristán, directora de Vogue España, no sufriera percance alguno tras adentrarse en las profundidades del metro madrileño. Afortunadamente, consiguió regresar a la superficie al cabo de media hora y sólo sufrió el estrés de saberse en peligro. “Fue una temeridad, pero es que no venía ni un taxi, la calle Serrano está toda levantada y llevaba unos Jimmy Choo con tacones de 15 centímetros”, argumenta Sacristán. La periodista, que nunca antes había utilizado un medio de transporte similar, asegura que no repetirá la experiencia aunque reconoce que ha sido enriquecedor “sentir por mí misma el riesgo de la jungla urbana”.

La periodista, que nunca antes había utilizado un medio de transporte similar, asegura que no repetirá la experiencia aunque reconoce que ha sido enriquecedor “sentir por mí misma el riesgo de la jungla urbana”.

La Policía cree que el hecho de que Sacristán no frecuente tertulias en horario de máxima audiencia televisiva ayudó a que la gente no intentara hacerle daño. “Es increíble, pese a todo, que tuviera las agallas de utilizar las escaleras mecánicas con lo alta que es y con el calzado que llevaba. Una caída habría roto esos bracitos de muñeca que tiene”, declara un agente.

Esta mañana, Sacristán ha sido recibida con aplausos al entrar en las dependencias de la editorial Condé Nast. Lourdes Garzón, compañera suya y directora de la revista Vanity Fair, no ha podido reprimir la emoción al verla llegar y ha exclamado “loca, loca, loca, loca, loca” con las manos en la cabeza.
