A clock that will last forever: Researchers propose a way to build the first space-time crystal
(Phys.org)—Imagine a clock that will keep perfect time forever, even after the heat-death of the universe. This is the "wow" factor behind a device known as a "space-time crystal," a four-dimensional crystal ...
Repulsive gravity as an alternative to dark energy (Part 1: In voids)
New project aims for fusion ignition
Russia and Italy have entered into an agreement to build a new fusion reactor outside Moscow that could become the first such reactor to achieve ignition, the point where a fusion reaction becomes self-sustaining ...
Dark energy is real, say astronomers
(Phys.org)—Dark energy, a mysterious substance thought to be speeding up the expansion of the Universe is really there, according to a team of astronomers at the University of Portsmouth and LMU University ...
A Theory of Dark Matter
Among the most astounding, unexpected, and important achievements of the past century (or even more) have been the discoveries of dark matter and dark energy, collectively dubbed the "dark sector."
New Data Suggests We Don’t Live in a Void, and Supports Dark Energy
Antigravity could replace dark energy as cause of Universe's expansion
Since the late 20th century, astronomers have been aware of data that suggest the universe is not only expanding, but expanding at an accelerating rate. According to the currently accepted model, this accelerated ...
Large Hadron Collider could test hyperdrive propulsion
Scientists Discover Light Force with 'Push' Power
(PhysOrg.com) -- A team of Yale University researchers has discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled ...
The day the universe froze: New dark energy model includes cosmological phase transition
Imagine a time when the entire universe froze. According to a new model for dark energy, that is essentially what happened about 11.5 billion years ago, when the universe was a quarter of the size it is today.
Surprising discovery: X-rays drive formation of new crystals
detect broken bones, tumors and dental cavities, analyze atoms in diverse materials and screen luggage at airports -- but who knew they could cause crystals to form?
Theorists Close In on Improved Atomic Property Predictions
(PhysOrg.com) -- Scientists at the National Institute of Standards and Technology and Indiana University have determined the most accurate values ever for a fundamental property of the element lithium using a novel approach ...
Zeroing in on quantum effects: New materials yield clues about high-temperature superconductors
(PhysOrg.com) -- A team of U.S. and Chinese physicists are zeroing in on critical effects at the heart of the latest high-temperature superconductors -- but they're using other materials to do it.
Magnetism observed in gas for the first time
(PhysOrg.com) -- For the first time, MIT scientists have observed ferromagnetism in an atomic gas, addressing the decades-old question of whether gases could show properties similar to a magnet made of iron or nickel. Specifically, ...
