Exclusive Alternate Scene from Gravity which Redefines the Entire Movie

"Hard to believe, but Oscar-winning director Alfonso Cuaron ("Children of Men") originally shot an opening scene for Gravity that would have radically changed the film. Too bad the brass at Warner Bros. rejected this version." [slyt | no spoilers | watch the last 15 seconds]

A Universe In Which Time Has No Beginning

"Maybe the Big Bang never happened because the universe never began because it has always existed." Scientific American magazine revisits the decade-old idea that we live in a "Rainbow" universe (where different wavelengths of light experience spacetime differently and where the big bang may never have happened) following the publication of new physics research on the subject.

Gravity

Alfonso Cuarón and Emmanuel Lubezki's 22 year collaboration continues to break new ground with the release of Gravity. Whether you enjoy Gravity or not, you may want to take a moment and consider the lengths to which Cuarón and Lubezki went to make Gravity a fully immersed cinematic experience.

"Ring it Out"

Last fall, the Canadian Space Agency asked students to design a simple science experiment that could be performed in space, using items already available aboard the International Space Station. Today, Commander Chris Hadfield conducted the winner for its designers: two tenth grade students, Kendra Lemke and Meredith Faulkner, in a live feed to their school in Fall River, Nova Scotia. And now, we finally have an answer to the age-old question, What Happens When You Wring Out A Washcloth In Space? [more inside]

The solution to quantum gravity is ready.

... and there is no dark matter/energy! Dr. Philip Mannheim has succeeded in developing a cosmological and quantum field theoretic consistent PT symmetric theory that contains no kind of dark matter and dark energy. Space is flat in the absence of matter, and even the largest galactic rotation curves are predicted. Perhaps most interestingly, it also handles the cosmological constant and zero-point energy 'problems' simultaneously! (This is the final paper in a long list of publications, but it makes the case such that it's importance is immediately recognized. I leave it to the experts to recognize it's true beauty.) All hail the internets!

Reflections on Pioneer

As they leave the solar system, the Pioneer spacecraft have anomalously decelerated, pointing to a possible gap in our understanding of gravity. Now, a computer graphics technique known as Phong shading predicts that the Pioneer anomaly is just a side effect of how the shape of the spacecraft reflects sunlight.

spacetime must organise itself in a way that maximises entropy

Gravity from Quantum Information
At the heart of their idea is the tricky question of what happens to information when it enters a black hole. Physicists have puzzled over this for decades with little consensus. But one thing they agree on is Landauer's principle: that erasing a bit of quantum information always increases the entropy of the Universe by a certain small amount and requires a specific amount of energy.

Dark Flow

Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]

Low-tech high-dive

At the Beijing Olympics this summer there is a camera that follows divers through the air until they hit the water's surface in glorious high-definition. The DiveCam was originally invented by Garrett Brown, the inventor of the Steadicam, and was first used in the 1996 Olympics in Atlanta. What new technology made this innovation possible? The power of gravity and pulleys.
