Two Russian scientists claim a device created to investigate the origins of the universe could become the world's first ever time machine

President seeks competitive edge with final budget request. In his final year as president, George W. Bush has put forward a budget wish-list that looks to restore his priorities in science and research, with solid increases for some physical sciences and pretty much no new money for the biomedical sector. Whether Congress will go along with this remains to be seen. In terms of research and development, the budgetÂ’s most pronounced feature is a 15% (US$1.6 billion) increase in physical-sciences spending year on year (see Table 1). In December 2007, last-minute negotiations in Congress derailed the second year of BushÂ’s...

Which math-phobic among us has not beseeched God for help with another colon-clenching algebra or calculus exam? Had we heeded the words of the German mathematician Leopold Kronecker, perhaps we would have realized we've been talking to the wrong person: "God made the integers; all else is the work of man." Pythagoras, who gave us his eponymous theorem on right-angled triangles, headed a cult of number worshippers who believed God was a mathematician. "All is number," they would intone. The 17th-century Jewish philosopher Baruch Spinoza echoed the Platonic idea that mathematical law and the harmony of nature are aspects of...

PARIS (AFP) - Astrophysicists believe they are closing in on one of the cosmos' great mysteries: why the expansion of the Universe, triggered by the Big Bang, is accelerating. The answer could be tantalisingly within reach, according to their study, released on Wednesday by the British weekly science journal Nature. A decade ago, astronomers were stunned to learn that the Universe was expanding more quickly than in the past. It had long been assumed that the mutual attraction of galaxies through gravity would slow the expansion of space, kicked off by the Big Bang some 14 billion years ago. Two...

Could The Universe Be Tied Up With Cosmic String? ScienceDaily (Jan. 21, 2008) — A team of physicists and astronomers from the University of Sussex and Imperial College London have uncovered hints that there may be cosmic strings - lines of pure mass-energy - stretching across the entire Universe. Cosmic strings are predicted by high energy physics theories, including superstring theory. This is based on the idea that particles are not just little points, but tiny vibrating bits of string Cosmic strings are predicted to have extraordinary amounts of mass - perhaps as much as the mass of the Sun...

Garrett Lisi: This surfer is no Einstein... Last Updated: 12:01am GMT 22/01/2008 No Einstein...but behind Garrett Lisi's 'theory of everything' lies an amazing idea, says Marcus du SautoyTwo months ago, the physics world was buzzing with the news of a new Einstein. Garrett Lisi, an unemployed physicist with no university affiliation who spent his time surfing in Hawaii, had come up with the Holy Grail of science: a theory unifying quantum physics and Einstein's theory of relativity.   Dude, where's my theory? Symmetry star Garrett Lisi The media went wild.However, in the last few weeks several physics blogs have uncovered a...

Two British researchers challenged the conventional history of mathematics in June when they reported having evidence that the infinite series, one of the core concepts of calculus, was first developed by Indian mathematicians in the 14th century. They also believe they can show how the advancement may have been passed along to Isaac Newton and Gottfried Wilhelm Leibniz, who are credited with independently developing the concept some 250 years later... historian of mathematics George Gheverghese Joseph of the University of Manchester, who conducted the research with Dennis Almeida of the University of Exeter... says that no one has yet firmly...

This bizarre picture is the outcome of a recent series of calculations that take some of the bedrock theories and discoveries of modern cosmology to the limit. Nobody in the field believes that this is the way things really work, however. And so in the last couple of years there has been a growing stream of debate and dueling papers, replete with references to such esoteric subjects as reincarnation, multiple universes and even the death of spacetime, as cosmologists try to square the predictions of their cherished theories with their convictions that we and the universe are real. The basic...

An impoverished surfer has drawn up a new theory of the universe, seen by some as the Holy Grail of physics, which has received rave reviews from scientists. Garrett Lisi, 39, has a doctorate but no university affiliation and spends most of the year surfing in Hawaii, where he has also been a hiking guide and bridge builder (when he slept in a jungle yurt). rr The E8 pattern (click to enlarge), Garrett Lisi surfing (middle) and out of the water (right) In winter, he heads to the mountains near Lake Tahoe, Nevada, where he snowboards.

A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth. A team of scientists compared leading theories of jets produced by rotating supermassive black holes with Chandra data. A sampling of nine giant galaxies that exhibit large disturbances in their gaseous atmospheres showed that the central black holes in these galaxies must be spinning at near their maximum rates....

The quasar OJ287 contains two black holes (this slightly dated illustration lists the larger black hole's mass as 17 billion Suns, though researchers now estimate it is 18 billion Suns). The smaller black hole crashes through a disc of material around the larger one twice every orbit, creating bright outbursts (Illustration: VISPA) The most massive known black hole in the universe has been discovered, weighing in with the mass of 18 billion Suns. Observing the orbit of a smaller black hole around this monster has allowed astronomers to test Einstein's theory of general relativity with stronger gravitational fields than ever...

CHICAGO (AFP) - Hundreds of rogue black holes may be roaming around the Milky Way waiting to engulf stars and planets that cross their path, US astronomers said Wednesday. The astronomers believe these "intermediate mass" black holes are invisible except in rare circumstances and have been spawned by mergers of black holes within globular clusters -- swarms of stars held together by their mutual gravity. These black holes are unlikely to pose a threat to Earth, but may engulf nebulae, stars and planets that stray into their paths, the researchers said. "These rogue black holes are extremely unlikely to do...

Beamish and Day are the only researchers in Canada conducting experimental research in this area of fundamental physics. At very low temperatures, helium gas turns into a liquid. Put under extreme pressure the liquid turns into a solid. Physicists have been manipulating solid helium so they can study its unusual behaviour. In 2004, a research team at Penn State university in the United States, led by Dr. Moses Chan, electrified the physics world when it announced that it may have discovered an entirely new state of matter - supersolidity. The team made the discovery by cooling solid helium to an...

If the universe contains more than three spatial dimensions, as many physicists believe, our current laws of gravity should break down at small distances. Nothing seems more certain than the "fact" that there are three dimensions of space. But can we be sure that there are only three dimensions? Imagine a tightrope walker balancing on a cable high above the ground. To the tightrope walker the cable is effectively a 1D object, because he only needs one coordinate to specify his position as he walks back and forth. But an ant, for instance, sees the cable as a 2D object,...

It's the end of the world - but not as we know it. A Spanish scientist suggests that the universe's end will come not with a bang but standstill - that time is literally running out and will, one day, stop altogether. Professor Jose Senovilla, of the University of the Basque Country, Bilbao, has put forward the theory as a rival to the idea of "dark energy" - the strange antigravitational force that is posited to explain a cosmic phenomenon that has baffled scientists. It was noticed ten years ago that distant stars - the ones on the very fringes...

WASHINGTON - The latest act of senseless violence caught on tape is cosmic in scope: A black hole in a "death star galaxy" blasting a neighboring galaxy with a deadly jet of radiation and energy. A fleet of space and ground telescopes have captured images of this cosmic violence, which people have never witnessed before, according to a new study released Monday by NASA. "It's like a bully, a black-hole bully punching the nose of a passing galaxy," said astrophysicist Neil deGrasse Tyson, director of the Hayden Planetarium in New York, who wasn't involved in the research. But ultimately, this...

The void: Imprint of another universe? 24 November 2007 Marcus Chown Magazine issue 2631 IN AUGUST, radio astronomers announced that they had found an enormous hole in the universe. Nearly a billion light years across, the void lies in the constellation Eridanus and has far fewer stars, gas and galaxies than usual. It is bigger than anyone imagined possible and is beyond the present understanding of cosmology. What could cause such a gaping hole? One team of physicists has a breathtaking explanation: "It is the unmistakable imprint of another universe beyond the edge of our own," says Laura Mersini-Houghton of...

Dr Gaurav Khanna is a professor at the University of Massachusetts. He has been renting supercomputers at NASA and the US National Science Foundation for US$20,000-$30,000 a year to run complicated calculations on just how much radiation is emitted in the process of a black hole swallowing a star... "For US$4,000 or so, I can get eight PS3s that can do the same task that I'd do on a supercomputer. For a one-time cost, I have this resource I can use privately. I can use it indefinitely over and over again. That's hugely attractive. That's why I considered the project....

The moon formed after a nasty planetary collision with young Earth, yet it looks odd next to its watery orbital neighbor. Turns out it really is odd: Only about one in every 10 to 20 solar systems may harbor a similar moon. New observations made by NASA's Spitzer Space Telescope of stellar dust clouds suggest that moons like Earth's are—at most—in only 5 to 10 percent of planetary systems. "When a moon forms from a violent collision, dust should be blasted everywhere," said Nadya Gorlova, an astronomer at the University of Florida in Gainesville who analyzed the telescope data in...
