Since the 1920’s, quantum physicists have been trying to make sense of an uncomfortable and startling possibility—that an infinite number of alternate universes exist. Leading scientists like Stephen Hawking, Michio Kaku and Neil Turok, all of whom are responsible for life-changing breakthroughs in the field of quantum physics, have all suggested the existence of multiple […]

Is ‘reality’ unreal? Scientists aim to find out

December 18, 2012

0

What if everything — all of us, the world, the universe — was not real? What if everything we are, know and do was really just someone’s computer simulation? The notion that our reality was some kid on a couch in the far future playing with a computer game like a gigantic Sim City, or […]

Megan Fellman – A Northwestern University research team has found a way to manufacture single laser devices that are the size of a virus particle and that operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors. Reducing the size of photonic and electronic elements […]

Physicists May Have Evidence Universe Is A Computer Simulation

October 27, 2012

4

Physicists say they may have evidence that the universe is a computer simulation. How? They made a computer simulation of the universe. And it looks sort of like us. A long-proposed thought experiment, put forward by both philosophers and popular culture, points out that any civilisation of sufficient size and intelligence would eventually create a […]

Quantum causal relations: A causes B causes A

October 2, 2012

1

Fabio Costa – One of the most deeply rooted concepts in science and in our everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. If an event A is a cause of an effect […]

Mouth of Giant Black Hole Measured for First Time

October 1, 2012

8

The point of no return: In astronomy, it’s known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be billions of times more massive than our sun may reside at the heart of most galaxies. Such supermassive black […]

Competing claims pile up around new element 113

October 1, 2012

0

It has teased researchers for almost a decade. But new evidence for the existence of super-heavy element 113 could see Japan claim its first spot on the periodic table – that is, unless a team in Russia wins official approval for its latest results and bags the right to name the element. Confirming the find […]

A scrambled-up material has broken the record for converting heat into electricity. Findings published today in Nature suggest that disorder may be the key to creating a new generation of energy-harvesting technologies1. Laptop owners and car mechanics alike know that heat is a major by-product of any kind of work. In power stations, for example, […]

Warp drive more realistic than previously thought

September 22, 2012

0

NASA scientists now think that the famous warp drive concept is a realistic possibility, and that in the far future humans could regularly travel faster than the speed of light.A warp drive would work by “warping” spacetime around any spaceship, which physicist Miguel Alcubierre showed was theoretically possible in 1994, albeit well beyond the current […]

Boiling water without bubbles

Quantum Teleportation Achieved over Record Distances

August 10, 2012

0

Two teams of researchers have extended the reach of quantum teleportation to unprecedented lengths, roughly equivalent to the distance between New York City and Philadelphia. But don’t expect teleportation stations to replace airports or train terminals—the teleportation scheme shifts only the quantum state of a single photon. And although part of the transfer happens instantaneously, […]

Pulsar star changes its beat – leaving astronomers puzzled

July 31, 2012

1

Pulsars are the ‘beacons’ of space – tiny, burnt out stars, which emit regular pulses of gamma rays – regular, that is, until scientists found one with hiccups. The pulsar J1838-0537 suddenly speeded up the rays it was blasting into space – and ‘glitched’, in a cosmic hiccup that scientists still don’t understand. Even finding […]
