Quantum measurement carries information even when the measurement outcome is unread
Quark asymmetries hint at physics beyond the Standard Model
World's best thermometer made from light
(Phys.org) —University of Adelaide physics researchers have produced the world's most sensitive thermometer – three times more precise than the best thermometers in existence.
Hubble extends stellar tape measure 10 times farther into space
(Phys.org) —Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away—10 times farther than previously possible.
Gravity measurements confirm subsurface ocean on Enceladus
In 2005, NASA's Cassini spacecraft sent pictures back to Earth depicting an icy Saturnian moon spewing water vapor and ice from fractures, known as "tiger stripes," in its frozen surface. It was big news ...
New study finds 'geologic clock' that helps determine Moon's age
An international team of planetary scientists determined that the Moon formed nearly 100 million years after the start of the solar system (4.470 billion years ago), according to a paper to be published April ...
Surface of Titan Sea is mirror smooth, scientists find
New radar measurements of an enormous sea on Titan offer insights into the weather patterns and landscape composition of the Saturnian moon. The measurements, made in 2013 by NASA's Cassini spacecraft, reveal ...
Most precise measurement of electron mass made
Scientists in Germany said Wednesday they had made the most precise measurement yet of the mass of the electron, one of the building blocks of matter.
Earth's core reveals an inner weakness
(Phys.org) —The word "core" conjures up an image of something strong. However, new experiments show that the iron found in the Earth's core is relatively weak. This finding is based on x-ray spectroscopy ...
IUPAC votes to change standard atomic weights of 19 elements
New measure of gravitational constant higher than expected
Physicist disentangles 'Schrodinger's cat' debate
Physicist Art Hobson has offered a solution, within the framework of standard quantum physics, to the long-running debate about the nature of quantum measurement.
'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.
Squeezed light produced using silicon micromechanical system
One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as ...
