Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Researchers demonstrate proof of creation of a mirror by optical matter
Superconductivity in orbit: Scientists find new path to loss-free electricity
(Phys.org) —Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor ...
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
With neutrons, scientists can now look for dark energy in the lab
It does not always take a huge accelerator to do particle physics: First results from a low energy, table top alterative takes validity of Newtonian gravity down by five orders of magnitude and narrows the ...
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
'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.
Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published ...
Physicists suggest possible existence of other kinds of dark matter
Scientists capture ultrafast snapshots of light-driven superconductivity
A new study pins down a major factor behind the appearance of superconductivity—the ability to conduct electricity with 100 percent efficiency—in a promising copper-oxide material.
Big Bang breakthrough team allows they may be wrong
American astrophysicists who announced just months ago what they deemed a breakthrough in confirming how the universe was born now admit they may have got it wrong.
