'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Scientists create light from vacuum
(PhysOrg.com) -- Scientists at Chalmers University of Technology have succeeded in creating light from vacuum observing an effect first predicted over 40 years ago. The results will be published tomorrow ...
Repulsive gravity as an alternative to dark energy (Part 2: In the quantum vacuum)
Four reasons why the quantum vacuum may explain dark matter
Boosting the force of empty space
Vacuum fluctuations may be among the most counter-intuitive phenomena of quantum physics. Theorists from the Weizmann Institute (Rehovot, Israel) and the Vienna University of Technology propose a way to amplify ...
Ephemeral vacuum particles induce speed-of-light fluctuations
New research shows that the speed of light may not be fixed after all, but rather fluctuates.
Single-atom transistor is 'perfect'
In a remarkable feat of micro-engineering, UNSW physicists have created a working transistor consisting of a single atom placed precisely in a silicon crystal.
Researchers create light from 'almost nothing'
Physicists describe method to observe timelike entanglement
May the force be with us? Precise measurements test quantum electrodynamics, constrain possible fifth fundamental force
Light particles illuminate the vacuum
Researchers from the Finnish Aalto University and the Technical Research Centre of Finland succeeded in showing experimentally that vacuum has properties not previously observed. According to the laws of ...
Qubits that never interact could exhibit past-future entanglement
Dark energy hides behind phantom fields
Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from ...
Physicists lay the groundwork for cooler, faster computing
University of Toronto quantum optics researchers Sajeev John and Xun Ma have discovered new behaviours of light within photonic crystals that could lead to faster optical information processing and compact computers that ...
