Scientists Report Finding Reliable Way to Teleport Data
Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

Researchers create the world’s most sensitive thermometer
According to a report from the University of Adelaide, Australia, physics researchers from the University’s Institute for Photonics and Advanced Sensing (IPAS) have built the most sensitive thermometer in the world, boasting a threefold advantage in precision over the best thermometers – 30 billionths of a degree. Interestingly, the thermometer uses light to measure temperature.

Physicists hunt for disappearing Da Vinci
Da Vinci is disappearing. This once-vibrant red chalk drawing by the master – widely believed to be a self-portrait – has faded into a dull watermark blotted by dark marks. Now the history behind the disappearance has been uncovered, offering hope that we can save what little is left of the famed face.

10 Reasons Why You Can’t Live Without A Particle Accelerator
Physicists use particle accelerators to answer questions of fundamental physics—how our universe was created, why objects have mass, and so on. Accelerators are huge—Fermilab’s Tevatron, near Chicago, is four miles in circumference, while the Large Hadron Collider in Geneva is more than four times that size—and extremely expensive. In some ways, they’re the epitome of the pure research instrument. But if you think these machines have no use outside of research, you’re in for a surprise.

Physicists finally explain why your earphones are always tangled
We performed experiments in which a string was tumbled inside a box and found that complex knots often form within seconds. We used mathematical knot theory to analyze the knots. Above a critical string length, the probability P of knotting at first increased sharply with length but then saturated below 100%. This behavior differs from that of mathematical self-avoiding random walks, where P has been proven to approach 100%.

Could time travel soon become a reality?
If a time traveller went back in time and stopped their own grandparents from meeting, would they prevent their own birth? That’s the crux of an infamous theory known as the 'grandfather paradox', which is often said to mean time travel is impossible - but some researchers think otherwise. A group of scientists have simulated how time-travelling photons might behave, suggesting that, at the quantum level, the grandfather paradox could be resolved

Teleportation Accomplished by Netherlands Physicists
Physicists at Delft University, Netherlands have teleported information. The teleportation took place over a distance of three meters (10 feet), and used a procedure called entanglement. The team achieved this teleportation with 100 percent reliability and without altering the pieces of matter. Teleportation of this nature has never been accomplished before outside of fiction.

First Evidence Of A Correction To The Speed of Light
When astronomers first observed light from a supernova arriving 7.7 hours after the neutrinos from the same event, they ignored the evidence. Now one physicist says the speed of light must be slower than Einstein predicted and has developed a theory that explains why...

It’s okay. Nothing really matters. We don’t actually exist, anyway. Or so the Higgs Boson particle suggests
IT took $10 billion, the world’s largest particle accelerator and decades of research, but now scientists are convinced: The universe doesn’t exist.

Have We Been Interpreting Quantum Mechanics Wrong This Whole Time?
For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as a definite location and instead existing everywhere and nowhere at once. Only when a particle is measured does it suddenly…

The most basic unknowable property of matter
When you think about the Universe on a global scale, you might think of the very large (like stars, galaxies, or clusters of galaxies), the very small (like cells, molecules, or individual atoms), or anywhere in between. The Universe, as you well know, encompasses it all.

China plans super collider
For decades, Europe and the United States have led the way when it comes to high-energy particle colliders. But a proposal by China that is quietly gathering momentum has raised the possibility that the country could soon position itself at the forefront of particle physics.
