An analysis of Einstein's 1931 paper featuring a dynamic model of the universe
A paper published in the European Physical Journal H provides the first English translation and an analysis of one of Albert Einstein's little-known papers, "On the cosmological problem of the general theory ...
Paper stirs up controversy over the nature of the quantum wave function
UQ researchers break the law -- of physics
(PhysOrg.com) -- Two UQ Science researchers have proved two famous physical laws that have been widely used for the past 25 years do not always work.
Cold atom laboratory chills atoms to new lows
(Phys.org) —NASA's Cold Atom Laboratory (CAL) mission has succeeded in producing a state of matter known as a Bose-Einstein condensate, a key breakthrough for the instrument leading up to its debut on the ...
Survey shows physicists can't agree on fundamental questions about quantum mechanics
Pulsars: The Universe's gift to physics
Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the Universe. Research on these extreme and exotic objects already has produced two Nobel Prizes. Pulsar researchers now are poised ...
New light shed on old dispute between Einstein and Bohr
In classical physics there are no uncertainties - the properties of matter on an atomic level are deterministic, that is to say predetermined. The theories of quantum mechanics, however, only say something ...
Physicist suggests Einstein could have beaten Bohr in famous thought experiment
Mission accomplished for Europe's cargo freighter
Europe's heaviest-ever cargo carrier to the International Space Station burned up in Earth's atmosphere Saturday in a controlled manoeuvre after a five-month mission, the European Space Agency (ESA) said.
Ultracold atoms reveal surprising new quantum effects
Vienna University of Technology physicists have studied the transition of quantum systems towards thermal equilibrium. They detected an astonishingly stable intermediate state between order and disorder. ...
The first model for capturing and condensing light under realistic conditions
Quantum particles can be divided into two types: fermions and bosons. When cooled down to near-absolute zero temperatures, bosons can condense together into a collective state of matter called a Bose-Einstein ...
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.
Europe set for record-breaking space launch
Nearly 40 years ago, European countries worried by US and Soviet dominance of space gave the green light to the first Ariane rocket, a wee launcher capable of hoisting a satellite payload of just 1.8 tonnes—the ...
On the deceleration behaviour of black holes
(PhysOrg.com) -- Researchers use the concept of "anti-kick" to explain why the speed suddenly decreases after the collision of such exotic objects.
