Stephen Hawking's doctoral thesis has been made publicly available online for the first time. The 119-page document submitted by then 24-year old Hawking is titled "Properties of an Expanding Universe", and covers several topics that have echoed through his career such as the origins of the universe, gravitational waves, and singularities.
Quantum computers are a tool of destruction, not creation, according to Alexander Lvovsky, Quantum Optics group leader at the Russian Quantum Center. All the sensitive data sent over the internet is encrypted in order to protect the privacy of the parties involved, but quantum computers can make modern cryptography obsolete.
Researchers at the Universities of York, Munich and Cardiff have discovered that all quantum particles exhibit a unique property known as ‘backflow,’ which gives them the ability to move in the opposite direction to the way in which they are being pushed.
A team of physicists from the University of Nebraska-Lincoln has created the brightest light ever produced on Earth that is one billion times brighter than the surface of the sun. To create this record-breaking light, the team fired an ultra high-intensity laser known as the DIOCLES laser at electrons suspended in helium. Their aim was to study how the laser’s photon scattered from each time it is struck.
A team of physicists at the Australian National University (ANU) have managed to stop light using a cloud of ultra-cold atoms. The experiment, reported in the Nature Physics, could be used to build a quantum logic gate - an important building block in the development of light-based quantum computer.
A team of physicists from University of Maryland has discovered that high-intensity laser is capable of producing violent swirls of optical energy that strongly resemble smoke rings. These donut-shaped light structures, known as 'spatiotemporal optical vortices' or STOVs, can travel along with the laser pulse at the speed of light and control the flow of energy around it.
The center of the earth is actually 2.5 years younger than its surface, and researchers say it all comes down to the effects of gravity as described by Einstein's theory of general relativity.
World's largest and most powerful particle accelerator, the Large Hadron Collider, went offline following a weasel gnawed through a 66-kilovolt power cable.
When water is put under extreme confinement, it exhibits a fourth state known as Tunneling.
