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?’

“‘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?

You Know You’re Gonna Be A Star.

‘This is something you’re going to tell your grandchildren about,’ the spokeswoman said on a recent tour of the lab. “You were here when they were about to get fusion ignition. ‘It’s like standing on the hill watching the Wright brothers’ plane go by.’” CNN’s John Sutter checks in with Livermore Labs’s National Ignition Facility, a few months shy of a long-awaited experiment in nuclear fusion.

If it works, it’ll be big doings, obviously, although we’re still several decades away from a miracle energy source even by the most optimistic predictions. “‘One gallon of seawater would provide the equivalent energy of 300 gallons of gasoline; fuel from 50 cups of water contains the energy equivalent of two tons of coal,’ the Livermore project’s website says.

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.)

A Republic of Knowledge.

“I believe it is not in our character, American character, to follow — but to lead. And it is time for us to lead once again. I am here today to set this goal: we will devote more than 3 percent of our gross domestic product to research and development. We will not just meet, but we will exceed the level achieved at the height of the space race, through policies that invest in basic and applied research, create new incentives for private innovation, promote breakthroughs in energy and medicine, and improve education in math and science.

It’s poetry in motion: In a clear break with his predecessor, President Obama pledges $420 billion for basic science and applied research. “And he set forth a wish list including solar cells as cheap as paint; green buildings that produce all the energy they consume; learning software as effective as a personal tutor; prosthetics so advanced that you could play the piano again and ‘an expansion of the frontiers of human knowledge about ourselves and world the around us.’” Huzzah! (And fwiw, I would also like more manned spaced exploration…and a jetpack.)
