Space-Time in a Bottle.

“‘This is an epic result,’ adds Clifford Will of Washington University in St. Louis…’One day,’ he predicts, ‘this will be written up in textbooks as one of the classic experiments in the history of physics.’“

Using “the most perfect spheres ever made by humans,” a NASA experiment known as Gravity Probe B finds evidence of space-time curvature, as Einstein predicted under general relativity. “Everitt recalls some advice given to him by his thesis advisor and Nobel Laureate Patrick M.S. Blackett: ‘If you can’t think of what physics to do next, invent some new technology, and it will lead to new physics. Well,’ says Everitt, ‘we invented 13 new technologies for Gravity Probe B. Who knows where they will take us?’”

Glimpses of Qward.

“‘What we’d like to do is see if there’s some difference that we don’t understand yet between matter and antimatter,” Professor Hangst said. ‘That difference may be more fundamental; that may have to do with very high-energy things that happened at the beginning of the universe. That’s why holding on to them is so important – we need time to study them.‘”

Scientists at the Large Hadron Collider in Cern have found a way to hold atoms of antimatter for a fraction of a second. “[T]he ability to study such antimatter atoms will allow previously impossible tests of fundamental tenets of physics….'[W]e need a lot more atoms and a lot longer times before it’s really useful – but one has to crawl before you sprint.’”

The (No) Big-Bang Theory.

“In his proposal, time and space can be converted into one another, with a varying speed of light as the conversion factor. Mass and length are also interchangeable, with the conversion factor depending on both a varying gravitational “constant” and a varying speed of light (G/c2). Basically, as the universe expands, time is converted into space, and mass is converted into length. As the universe contracts, the opposite occurs.“

By way of cdogzilla, PhysOrg’s Lisa Zyga describes a new cosmological theory by Wun-Yi Shu of Taiwan that, among other things,does away with the Big Bang. “Essentially, this work is a novel theory about how the magnitudes of the three basic physical dimensions, mass, time, and length, are converted into each other…The theory resolves problems in cosmology, such as those of the big bang, dark energy, and flatness, in one fell stroke.”

Nothing New Under the Burning Sun.

“‘This world is a strange madhouse. Currently, every coachman and every waiter is debating whether relativity theory is correct. Belief in this matter depends on political party affiliation.’ So wrote Albert Einstein in a letter to his one time collaborator, the mathematician Marcel Grossmann in 1920.“

A recent history-of-science paper by a Jeroen van Dongen of Utrecht University looks into the anti-relativity theory movement of the 1920’s, and how it compares to today’s climate change denialism. “Anti-relativists were convinced that their opinions were being suppressed. Indeed, many believed that conspiracies were at work that thwarted the promotion of their ideas.” (See also: Evolution and Scopes.)

Whither the Darkness?

“If DAMA’s signal were due to dark matter, Xenon 100 would have seen dozens of events — unless the properties of dark matter are very different than expected, says Lang. ‘If DAMA really does see dark matter, it has to be something very, very exotic, something much different from what we expect, so it’s getting a bit unlikely.‘” A new study casts doubt on apparent discoveries of dark matter particles by the DAMA experiment. Back to MOND, then?

Now We’ve Done It.

Don’t say we weren’t warned: In the wake of the historic particle smashing by the LHC earlier this week, strange and potentially life-threatening anomalies have been reported all around the world, and they’re increasing in both magnitude and frequency. “Dr. Isadora Chin, a spokeswoman for the SCP Foundation, said that several of the anomalies had been granted ‘Euclid’ and even ‘Keter’ status, the designation for life-threatening manifestations of unusual size or behavior…Several have already been relocated to an observation facility in Black Mesa, New Mexico, she said.“

(Maybe Black Mesa? That was a joke, ha ha, fat chance.) Y’know, to be honest, I blame the time travelers from the future who should’ve come back and prevented these catastrophic rips in the fabric of space-time. Bang up job, you effing slackers.

Shedding Light on (a) Dark Matter?

“The second law states that a force is proportional to an object’s mass and its acceleration. But since the 1980s, some physicists have eyed the law with suspicion, arguing that subtle changes to it at extremely small accelerations could explain the observed motion of stars in galaxies.” Also on the subject of spinning, a new experiment finds a way to test Modified Newtonian Dynamics (MOND) on Earth, which, if successful, could revise Newton’s heretofore ironclad 2nd law…and explain away the longstanding dark matter problem. (By way of my new favorite Twitter feed, @newscientist.)

Next Stop, Alderaan.

“‘We are still coming to terms with just how smooth the LHC commissioning is going,’ said CERN Director General Rolf Heuer as the record was announced. ‘It is fantastic.’” Atoms or systems into ruin hurl’d, And now a bubble burst, and now a world…Also in science news, the now armed and fully operational Large Hadron Collider is breaking particle beam records as it warms up for the Big Show, when its handlers will work to recreate the conditions at one billionth of a second after the Big Bang. “Said Heuer: ‘We are continuing to take it step by step, and there is a lot to do before we start [first] physics in 2010. I’m keeping my champagne on ice until then.’” (By way of Dangerous Meta.)

100 DVDs, 1 Disc(overy).

“‘If this can really be done, then G.E.’s work promises to be a huge advantage in commercializing holographic storage technology,’ said Bert Hesselink, a professor at Stanford and an expert in the field.” Scientists at GE develop a way to compress 500 gigs of information onto a standard disc, equivalent to 100 DVDs or 20 Blu-Rays. That should free up some shelf space. “The recent breakthrough by the team, working at the G.E. lab in Niskayuna, N.Y., north of Albany, was a 200-fold increase in the reflective power of their holograms, putting them at the bottom range of light reflections readable by current Blu-ray machines.”

A Measure of Darkness.

“‘We’ve discovered this incredible dark energy, we don’t understand what the hell it is,’ said Lawrence Krauss, a physicist at Arizona State University. ‘It’s extremely small, extremely weak, and it’s so close to being zero, it’s just a total mystery why it should have this small value and not be zero.” While they’re still not entirely sure what in fact they’re looking at, Harvard-Smithsonian astrophysicists announce they’ve found another way to measure and quantify “dark energy”, a.k.a. the repulsive “cosmological constant” force causing the universe to expand rather than contract. “This is a much-needed confirmation that the earlier work was correct, the astronomers said, comparing it to football referees examining a controversial play with multiple camera angles.“

As an added bonus, the results announced today also seem to confirm Einstein’s general theory of relativity. “‘It’s never been proved right on the scale of the observable universe,’ Spergel said.”
