Clumped galaxies give General Relativity its toughest test yet
(Phys.org) —Nearly 100 years since Albert Einstein developed general relativity, the theory has passed its toughest test yet in explaining the properties of observable Universe. The most precise measurements ...
Computer simulation supports a "holographic" theory describing a black hole
A "holographic" theory, which was conjectured to describe accurately the dynamical phenomena occurring in a black hole, has been tested numerically by a research group composed of four researchers: Masanori ...
Engineers building hard-working mining robot
(Phys.org)—After decades of designing and operating robots full of scientific gear to study other worlds, NASA is working on a prototype that leaves the delicate instruments at home in exchange for a sturdy ...
SustainX builds 1.5 MW isotherm compressed air energy storage system
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."
Theorists apply loop quantum gravity theory to black hole
Penn astrophysicists zero in on gravity theory
(Phys.org) -- Most people take gravity for granted. But for University of Pennsylvania astrophysicist Bhuvnesh Jain, the nature of gravity is the question of a lifetime. As scientists have been able to see ...
Quantum causal relations: A causes B causes A
A deeply rooted concept in 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. Physicists from the ...
Out-of-fuel European satellite to come crashing down
A satellite monitoring Earth's gravity field since 2009 will run out of fuel "in the coming days" and eventually crash, with little risk to humans, the European Space Agency said Friday.
Interstellar travelers may be helped by physicist's calculations that solve the Pioneer anomaly
(Phys.org)—Former President Bill Clinton recently expressed his support for interstellar travel at the 100 Year Spaceship Symposium, an international event advocating for human expansion into other star ...
Rapunzel, Leonardo and the physics of the ponytail
(PhysOrg.com) -- New research provides the first mathematical understanding of the shape of a ponytail and could have implications for the textile industry, computer animation and personal care products.
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.
Hypergravity helping aircraft fly further
(Phys.org)—ESA research has helped to develop an aircraft-grade alloy that is twice as light as conventional nickel superalloys while offering equally good properties. The path to creating this alloy required ...
Spacetime ripples from dying black holes could help reveal how they formed
(Phys.org)—Researchers from Cardiff University have discovered a new property of black holes: their dying tones could reveal the cosmic crash that produced them.
