writes: Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics — so strange, in fact, that Albert Einstein famously referred to it as “spooky action at a distance.”
Essentially, entanglement involves two particles, each occupying multiple states at once — a condition referred to as superposition. For example, both particles may simultaneously spin clockwise and counterclockwise. But neither has a definite state until one is measured, causing the other particle to instantly assume a corresponding state. The resulting correlations between the particles are preserved, even if they reside on opposite ends of the universe.
But what enables particles to communicate instantaneously — and seemingly faster than the speed of light — over such vast distances? Earlier this year, physicists proposed an answer in the form of “wormholes,” or gravitational tunnels. The group showed that by creating two entangled black holes, then pulling them apart, they formed a wormhole — essentially a “shortcut” through the universe — connecting the distant black holes.Link to Original Source

Simulations were carried out using the Geant4 (Geometry and tracking) software toolkit released by the CERN accelerator laboratory for Monte Carlo simulation of the interaction of particles with matter and fields. Geant permits a more sophisticated and comprehensive design and optimization of antimatter engines than the software environment for simulations reported by prior researchers. The main finding is that effective exhaust speeds Ve ~ 0.69c (where c is the speed of light) are feasible for charged pions in beamed core propulsion, a major improvement over the Ve ~ 0.33c estimate based on prior simulations.Link to Original Source

The Bill C-11 legislative committee concluded its clause-by-clause review yesterday as eight government amendments were added to the bill and all opposition amendments were defeated. The amendments included an expanded enabler provision and some modest tinkering to other elements of the bill. There are still several steps needed before the bill passes including third reading at the House of Commons, Senate review, and ultimately royal assent, but Canadian copyright reform is well on its way to completion before the summer starts.
In the days leading up to the clause-by-clause review, many focused on three key issues: no SOPA-style amendments such as website blocking or warrantless disclosure of information, maintaining the fair dealing balance found in the bill, and amending the digital lock provisions. By that standard, the changes could have been a lot worse. The government expanded the enabler provision, though not as broadly as CIMA requested. Virtually all other copyright lobby demands — website blocking, notice-and-takedown, iPod tax, copyright term extension, disclosure of subscriber information — were rejected. Moreover, the provisions supported by consumer and education groups including user generated content protection, time shifting, format shifting, backup copies, Internet provider liability, and statutory damages reform were left untouched. This represents a major victory for the many Canadians and groups such as Open Media that spoke out on these issues.
