Researchers suggesting that the speed of light varies have come up with a numerical prediction that will allow their theory to be tested. Many theories in physics are built upon the idea that the speed of light is at a constant rate, but João Magueijo and Niayesh Afshordi think otherwise. In a paper published in the journal Physical Review D, they detailed the creation of an exact figure on the spectral index, a model that can be used to determine if their theory is valid or not. All structures in the universe today were created when fluctuations occurred in the...

WWith hindsight, it seems as though scientific breakthroughs sweep quickly to universal acceptance. A paper is published and everybody says, “Eureka!” But that’s not necessarily the case. Sometimes scientists have too much invested in the status quo to accept a new way of looking at things. This was certainly true when Albert Einstein‘s 1905 paper on “special relativity” first challenged the British conception of ether. Einstein argued that space and time were bound up together (something he would elaborate on in his theory of general relativity of 1915, adding gravity to the mix of space/time), a complicated idea that contradicted...

For nearly 20 years, physicists have known that the expansion of the universe has begun to speed up. This bizarre acceleration could arise because some form of mysterious dark energy is stretching space. Or, it could signal that physicists' understanding of gravity isn't quite right. But a new study puts the screws on a broad class of alternative theories of gravity, making it that much harder to explain away dark energy. The study is also path setting because it exploits an effect called weak lensing in which the gravity from closer galaxies distorts the images of more distant ones. "That's...

Real Clear Science ^ | Ross Pomeroy
The idea that our Universe is filled with dark matter has been around for nearly a century. When astronomers noticed that orbital speeds towards the edges of spiral galaxies remain the same or even increase slightly, rather than decrease, they surmised that either there must be some huge unseen mass driving the rotation, or that the laws of gravity given by Einstein's General Relativity need to be changed. They elected the first option. Over that time, cosmologists have accumulated boatloads of evidence in favor of the notion that this invisible, "dark" matter -- which neither interacts with nor emits light...

+Plus ^ | Yen Chin Ong
The shape of a Schwarzschild black hole is that of a sphere, and so its area is $A=4\pi r_ h^2$. We might be tempted to use our ordinary intuition about geometry, and deduce that the volume of a Schwarzschild black hole must be $V=4/3 \pi r_ h^3$. This is, however, not necessarily the case. It turns out that the volume of a black hole is not a well-defined notion in general relativity. The reason is that general relativity is a geometric theory of a four-dimensional spacetime, that is, three dimensions of space and one dimension of time. In order to...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed. This brings up all sorts of interesting questions, including this one from reader (and Patreon supporter!) Joe Latone, who asks: "Are gravity waves expected to exhibit wave-particle duality, and if so, have LIGO physicists already conceived of ways to test it, like the double-slit experiment?" It started out simply enough: matter was made of particles, things like atoms and their constituents, and radiation was made of waves....

The Universe we know and love - with Einstein's General Relativity as our theory of gravity and quantum field theories of the other three forces - has a problem that we don't often talk about: it's incomplete, and we know it. Einstein's theory on its own is just fine, describing how matter-and-energy relate to the curvature of space-and-time. Quantum field theories on their own are fine as well, describing how particles interact and experience forces. Normally, the quantum field theory calculations are done in flat space, where spacetime isn't curved. We can do them in the curved space described by...

Physics is built out of philosophically fascinating ideas. Or, at least, ideas that fascinate us as physicists. We are often moved to reverentially proclaim the beauty of various concepts and theories. Sometimes this beauty makes sense to other people (we're made of star stuff) and other times it's opaque (Frobenius manifolds in psuedo-Euclidean spaces). I have my own personal favorite idea. It arises from the philosophically fantastic (but mathematically moderate) workings of Einstein's relativity theory. The theory of special relativity holds that time and space are not separate entities, each operating on its own; rather they are intimately and inextricably...

Even more remarkable is that Lisi, who has a Ph.D. but no permanent university affiliation, solves the problem without resorting to exotic dimensions, string theory or exceptionally complex mathematics. A successful Grand...

Another Theory of Relativity by: Malcolm A. Kline, November 06, 2007 Relativists, beware. The professors who tell you that “Everything is relative” probably fail to relate how destructive an idea that is. In an interview with Hillsdale College’s Imprimis magazine, Supreme Court Justice Clarence Thomas noted “the connection between relativism, nihilism, and Naziism.” “The common idea that you can do whatever you want to do, because truth and morality are relative, leads to the idea that if you are powerful enough, you can kill people because of their race or faith,” Justice Thomas explains. “So ask your relativist friends sometime:...

A pair of German physicists claim to have broken the speed of light - an achievement that would undermine our entire understanding of space and time. According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second. However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory. The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of...

AFTER more than 90 years, scientists believe they may have found experimental proof for general relativity, one of Albert Einstein’s greatest theories. Scientists announced yesterday that early results from Gravity Probe B (GP-B), the £400m space mission carrying the first experiments capable of testing the theory, suggested that Einstein was right. The researchers cautioned that they still had several months of work to confirm the result. However, the announcement, made at the annual meeting of the American Physical Society, is seen as highly significant. Since its launch by Nasa in April 2004, GP-B has been using four ultra-precise gyroscopes to...

What do Volvo, Ericsson, Saab and IKEA have in common? The people of Sweden have more faith in them than in the church. Perhaps the news shouldn't come as much of a surprise, coming as it does from a country best known for its meatballs and the bright blue and yellow warehouses selling cheap and cheerful furniture around the globe. Still, preacher men the world over must be reeling. A new poll taken of Swedes indicates that more people trust IKEA than the church in the largely Protestant country. According to the poll, taken by the business weekly Dagens Industri,...

September 14, 2006 - An international research team led by Prof. Michael Kramer of the University of Manchester’s Jodrell Bank Observatory, UK, has used three years of observations of the “double pulsar”, a unique pair of natural stellar clocks which they discovered in 2003, to prove that Einstein’s theory of general relativity–the theory of gravity that displaced Newton’s–is correct to within a staggering 0.05%. Their results are published on the14th September in the journal Science and are based on measurements of an effect called the Shapiro Delay. The double pulsar system, PSR J0737-3039A and B, is 2000 light-years away in...

"Whoever undertakes to set himself up as a judge in the field of truth and knowledge is shipwrecked by the laughter of the Gods." —Albert Einstein  The general, historical dialogue between religion and science goes back a long way—at least to Plato, Aristotle, and Leibniz. Before the 17th century, the goals of science were wisdom, understanding the natural order, and living in harmony with it. Ever since the "quantum revolution" of about 70 years ago, various scientists have been finding the intriguing parallels between their results and certain mystical-transcendental religions. Heisenberg, Bohr, Schroedinger, Eddington, Einstein—all held a mystical, spiritual...
