Roll Over Einstein? Not so fast.


‘We tried to find all possible explanations for this,’ the report’s author Antonio Ereditato of the Opera collaboration told BBC News on Thursday evening. ‘We wanted to find a mistake – trivial mistakes, more complicated mistakes, or nasty effects – and we didn’t.
When you don’t find anything, then you say “well, now I’m forced to go out and ask the community to scrutinise this”.’

As broke everywhere last week, CERN appears to find evidence of neutrinos moving faster than light(!) — time travel possible which would, well, basically rewrite the laws of physics and make. (See what I did there? Anyway, kind of a big deal!)

Fermilab is currently trying to reproduce the results, but for now, the scientific community is, shall we say, skeptical. “Extraordinary claims require extraordinary evidence. I think it will be perceived in retrospect as an embarrassment that this claim received so much publicity–the inevitable consequence of posting a preprint on the Web.

Update: Sorry, aspiring Marty McFlys: As expected, rumors of relativity’s demise have been greatly exaggerated. Here’s the rub: “[T]he distance that the neutrinos had to travel in their reference frame is longer than the distance that the neutrinos had to travel in our reference frame, because in our reference frame, the detector was moving towards the source.” Thus, thte experiment “helps to reinforce relativity rather than question it.

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?’

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.)
