Grey is the new black hole: is Stephen Hawking right?
Over the past few days, the media has cried out the recent proclamation from Stephen Hawking that black holes, a mystery of both science and science fiction, do not exist. ...
Venus mountains create wave trains
(Phys.org) —The planet Venus is blanketed by high-level clouds. At visible wavelengths, individual cloud features are difficult to see, but observations made by instruments on ESA's Venus Express orbiter ...
Why Einstein will never be wrong
One of the benefits of being an astrophysicist is your weekly email from someone who claims to have "proven Einstein wrong". These either contain no mathematical equations and use phrases such as "it is obvious ...
Newly discovered celestial object defies categories
An object discovered by astrophysicists at the University of Toronto (U of T) nearly 500 light years away from the Sun may challenge traditional understandings about how planets and stars form.
How hypergravity impacts electric arcs
A new study on electric discharge behaviour under intense gravitational forces shows that its dynamic changes as gravity increases.
Creation of entanglement simultaneously gives rise to a wormhole
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics—so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."
Earthquake scars Earth's gravity
(Phys.org) —ESA's GOCE satellite has revealed that the devastating Japanese earthquake of 2011 left its mark in Earth's gravity – yet another example of this extraordinary mission surpassing its original ...
Proton radius puzzle may be solved by quantum gravity
UAH research into April 2011 tornadoes uncovers insights
Research into the violent storms that spawned killer tornadoes across Alabama and the southeastern U.S. in April 2011 continues to uncover insights into what might have caused so many powerful tornadoes, plus information ...
X-ray vision for road diggers: The next quantum leap?
Quantum mechanics has been hailed as the next big thing in technology. And quantum computers are a media favourite. But there is a little-known quantum technology that can peer beneath the earth, which could ...
Meteorite impact structure reveals mineral deposit hotspots
The world's largest and oldest meteorite impact structure has been discovered through research on the formation of gold deposits in WA's Eastern Goldfields.
ESA: Satellite causes no damage after re-entry
The European Space Agency says one of its research satellites that had run out of fuel caused no known damage after re-entering the Earth's atmosphere.
NASA pursues new geodesy application for emerging atom-optics technology
NASA technologists working to advance a pioneering technology that promises to detect tiny perturbations in the curvature of space-time now want to apply the same technique to map variations in Earth's gravity ...
Gravity plays a role in keeping cells small
(Phys.org) —The effects of gravity are relevant when building houses or flying airplanes, but biologists have generally accepted that the average cell is too small for gravity to play a role in how it is ...
