Can We Finally Break The Speed Of Light?

Space time mapped out: Teams at NASA are exploring ways to warp the universe to enable faster than light travel. Pictured is a model of how a ship, enclosed in a space-time 'doughnut', could reach the stars

Can We Finally Break The Speed Of Light? Nasa Breakthrough Suggests Star Trek's 'Warp Drives' May Not Only Be Possible - But Practical -- Daily Mail

* NASA suggests new model which could reduce energy requirements for warp-speed travel from planet-sized to car-sized
* 'Humble experiments' in laboratory could lead to faster-than-light travel

As we take our virgin steps into space, there is one thing that could always put a cap on our ambitions.

Despite our desire to explore the stars, we are limited by travelling at less than light speed - and even if we managed to match that pace, we would still be listing our voyages from star to star in years, centuries or millenia.

But, in what could be a huge breakthrough, theorists from Nasa say there is 'hope' that we can achieve faster-than-light travel, after physicists found a theoretical possibility for warp speed travel.

The Next Holy Grail For Physics: Finding The Anti-World -- Spiegel Online

The apparent discovery of the Higgs boson was hailed as a historic milestone, but for particle physicists it mainly marks the beginning of a new search. Rival teams at CERN in Switzerland are trying to decipher the secrets of antimatter. If they succeed, the laws of physics will have to be rewritten.

Sheep are grazing to the left of the gate to the anti-world. On the right-hand side, a pair of rust-brown steel bottles is waiting to be picked up. A sign warns: "Caution. Radiation!" Another sign prohibits the use of bicycles.

Search For The 'God Particle' Coming To An End?

Chicago's Tevatron particle accelerator: Analyzing data from some 500 trillion sub-atomic particle collisions designed to emulate conditions right after the Big Bang, scientists at Fermilab outside Chicago produced some 1,000 Higgs sightings over a decade of work.

'End Game' For The Higgs: U.S. Particle Collider Helps Prove Einstein Right With New Sightings Of Elusive 'God Particle' -- Daily Mail

A second particle collider - Chicago's Tevatron - has captured glimpses of the elusive Higgs boson, the ‘God particle’ that would complete Albert Einstein's theory of the universe.

The probability that the particles are not the Higgs, but instead a statistical fluke is now just 1 in 250.

Tevatron's sighting tally with measurements from CERN's Large Hadron Collider, which is to 'turn up' its beams this year to find the particle by Christmas.

'The end game is approaching in the hunt for the Higgs boson,' said Jim Siegrist, Associate Director of Science for High Energy Physics.

Were Neutrinos Faster-Than-Light .... Or Not?

'Faster-Than-Light' Particles May Have Been Even Speedier -- CBC

Subatomic particles clocked at speeds exceeding the speed of light may have been going even faster than they appeared, physicists say.

A problem with some of the equipment used in the original experiment may have led to an overestimate of the time it took the particles, known as neutrinos, to make their 730-kilometre journey, reported CERN, the European Organization for Nuclear Research in a statement Thursday.

As a result, their speed may have been underestimated.

The Biggest Unsolved Mysteries In Physics

We've learned so much from science, bet there's plenty we still don't understand

5 Of The Biggest Unsolved Mysteries In Physics -- Y!Tech/Yahoo News

The mysteries of the universe are as vast and wide as existence itself. Throughout history, mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker's Guide to the Galaxy, "I think the problem, to be quite honest with you, is that you've never actually known what the question is."

From Live Science:

A report in April suggesting a giant atom smasher may have detected a never-seen-before subatomic particle had physicists at the edge of their seats with hope, albeit with a healthy dose of skepticism. Now an independent test of the results suggests it was just a fluke.

The tantalizing signal came from the Tevatron particle accelerator at the Fermilab physics laboratory in Batavia, Ill. Inside the accelerator there, particles race around a 4-mile (6.3 km) ring at near light speed. When two particles collide, they disintegrate into other exotic particles in a powerful outpouring of energy. [Wacky Physics: The Coolest Little Particles in Nature]

Electrons Are Almost Perfectly Round, Scientists Discover -- The Telegraph

Electrons may be the most round natural objects in the universe, a study has discovered.

Researchers at Imperial College London have made the most accurate measurement yet of the shape of an electron, finding that it is almost a perfect sphere.

Experts found that the subatomic particles differ from being perfectly round by less than 0.000000000000000000000000001cm.

From New Scientist:

Atoms called positronium inexplicably scatter off gas particles as if they were lone electrons, even though they contain an anti-electron as well. The finding hints that engineers could use the well-known scattering properties of electrons as a rule of thumb in designing future medical scanners that employ positronium. It could also help interpret puzzling astronomical observations.

The Ultimate Field Guide to Subatomic Particles

From io9:

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles.

This is, as you might imagine, a pretty big topic, so we're splitting it into (at least) two posts. Today we're going to deal with just the particles that physicists are certain (or, at least, reasonably certain) exist, and then tomorrow we'll get into the even stranger world of particles that have been hypothesized but may or may not actually exist. I've also made a handy cheat sheet listing all the elementary particles and their vital statistics, which you can find here. But to understand what all of that means, you'll really want to read on.

Electron Vortex Could Trap Atoms

From New Scientist:

Set a beam of electrons twisting, and the resulting vortex could be just the tool to manipulate atoms.

"This is a fundamentally new state that we can bring electrons into," says Jo Verbeeck from the University of Antwerp, Belgium.

Optical vortices, made of twisting beams of light, have been used to spin or move micrometre-sized particles like cells. But electron vortices could potentially trap much smaller particles, says Verbeeck.

The Math Behind the Physics Behind the Universe

Discover Interview: The Math Behind the Physics Behind the Universe -- Discover Magazine

Shing-Tung Yau explains how he discovered the hidden dimensions of string theory.

Shing-Tung Yau is a force of nature. He is best known for conceiving the math behind string theory—which holds that, at the deepest level of reality, our universe is built out of 10-dimensional, subatomic vibrating strings. But Yau’s genius runs much deeper and wider: He has also spawned the modern synergy between geometry and physics, championed unprecedented teamwork in mathematics, and helped foster an intellectual rebirth in China.

Are We Closer To A 'Theory Of Everything'?

From The BBC:

The physicists' ultimate dream is the search for a "theory of everything", a unifying explanation that can make sense of the infinitely tiny as well as the infinitely large.

From the strange particles that are the terrain of atom-smashing machines such as the Large Hadron Collider (LHC) at Cern, to galaxies beyond our own, about which we're learning more and more through increasingly powerful telescopes and observatories.

Ye Cannae Change The Laws Of Physics. Or Can You?

From The Economist:

RICHARD FEYNMAN, Nobel laureate and physicist extraordinaire, called it a “magic number” and its value “one of the greatest damn mysteries of physics”. The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen. One consequence would be that squishy, carbon-based life would not exist.

From Science Daily:

ScienceDaily (Apr. 23, 2010) — Supercooling, a state where liquids do not solidify even below their normal freezing point, still puzzles scientists today. A good example of this phenomenon is found everyday in meteorology: clouds in high altitude are an accumulation of supercooled droplets of water below their freezing point.

From Science Daily:

ScienceDaily (Mar. 30, 2010) — For a brief instant, it appears, scientists at Brook­haven National Laboratory on Long Island recently discovered a law of nature had been broken.

Action still resulted in an equal and opposite reaction, gravity kept the Earth circling the Sun, and conservation of energy remained intact. But for the tiniest fraction of a second at the Relativistic Heavy Ion Collider (RHIC), physicists created a symmetry-breaking bubble of space where parity no longer existed.
