Physicist suggests some types of wormholes may stay open long enough to send a photon through
Philosopher untangles Einstein senility controversy
When it comes to looking at reality from the subatomic perspective of quantum theory, many physicists are nearly as much in the dark as the average person on the street.
Einstein's 'spooky' theory may lead to ultra-secure internet
(Phys.org) —Einstein's scepticism about quantum mechanics may lead to an ultra-secure internet, suggests a new paper by researchers from Swinburne University of Technology and Peking University.
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 ...
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 ...
Einstein's conversion from a static to an expanding universe
Albert Einstein accepted the modern cosmological view that the universe is expanding long after his contemporaries, new study shows.
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 ...
Scientists demonstrate quantum phenomenon for the first time using a plastic film
For the first time, scientists at IBM Research have demonstrated a complex quantum mechanical phenomenon known as Bose-Einstein condensation (BEC), using a luminescent polymer (plastic) similar to the materials ...
Scientists predict coreless vortex in ultracold atoms
Swirling, persistent vortices can be created in superfluid helium. Generally no atoms sit at the eye of these miniature hurricanes. Things might be different in condensates of ultracold atoms. Theorists at ...
'Spooky action' builds a wormhole between 'entangled' quantum particles
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as "spooky action at a distance," could be even spookier than Einstein perceived.
Quantum 'sealed envelope' system enables 'perfectly secure' information storage
A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity - allowing the sender ...
Theoretical physics – like sex, but with no need to experiment
There are not many professions where people routinely ask you to justify your work, but theoretical physics one of them. In the wake of the recent Nobel Prize to Peter Higgs and François Englert for their ...
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.
European cargo freighter undocks from ISS
Europe's heaviest-ever cargo carrier to the International Space Station undocked on Monday after completing its mission, and will burn up in Earth's atmosphere on Saturday, the NASA space agency said.
