Does weak equivalence break down at the quantum level?
Dec 08, 2009 |
4.5 / 5 (26) |
18
(PhysOrg.com) -- One of the givens in physics is the weak equivalence principle. This principle has been considered solid since Einstein proposed that it is not possible to detect the difference between uniform acceleration ...
Buffer gas cooling could open up the field of ultracold physics
Sep 17, 2009 |
4.8 / 5 (23) |
2
(PhysOrg.com) -- "Scientists have been making Bose-Einstein Condensates [BECs] for nearly 15 years," Charlie Doret tells PhysOrg.com. "Essentially all BEC research to date, however, begins with laser cooling. Unfortunately, ...
New Law of Physics Could Explain Quantum Mysteries
Aug 17, 2009 |
4.5 / 5 (98) |
163
(PhysOrg.com) -- Since the early days of quantum mechanics, scientists have been trying to understand the many strange implications of the theory: superpositions, wave-particle duality, and the observer’s ...
Physicists Propose a Method to Observe Dirac Monopoles
Jul 28, 2009 |
4.6 / 5 (18) |
5
(PhysOrg.com) -- For decades, scientists have been intrigued by the hypothetical existence of magnetic monopoles - particles with only a north or south magnetic pole, thus having a nonzero magnetic charge. ...
In Twin Paradox Twist, the Accelerated Twin is Older
Jun 09, 2009 |
3.4 / 5 (42) |
85
Just when you thought you were beginning to understand the twin paradox (maybe), scientists have found something new to ponder. In the original version of the famous thought experiment on time dilation, one ...
Quantum Mysticism: Gone but Not Forgotten
Jun 08, 2009 |
4.4 / 5 (52) |
43
Does mysticism have a place in quantum mechanics today, or is the idea that the mind plays a role in creating reality best left to philosophical meditations? Harvard historian Juan Miguel Marin argues the ...
Studying the 'mountains' and 'starquakes' that develop on neutron stars
May 26, 2009 |
3.8 / 5 (13) |
1
(PhysOrg.com) -- Neutron stars have the potential to play an important role in understanding some of the mysteries of the universe. One of factors that could help lead to an understanding of gravitational waves and the mechanisms ...
Can R2 gravity explain dark matter?
Apr 20, 2009 |
3.5 / 5 (64) |
50
(PhysOrg.com) -- "In many ways, the standard model of cosmology works very well," Jose Cembranos tells PhysOrg. "However, there are very basic features that we just do not know. We have dark energy and dark matter. They d ...
Entangled Light in Bose-Einstein Condensates
Apr 08, 2009 |
4.4 / 5 (16) |
13
(PhysOrg.com) -- When physicists entangle light, they usually use nonlinear crystals as the source. However, it’s difficult to control the entanglement generation process in a bulk crystal, and so scientists ...
Study Rules Out Fröhlich Condensates in Quantum Consciousness Model
Mar 10, 2009 |
3.9 / 5 (36) |
17
(PhysOrg.com) -- Scientists don't fully understand how consciousness works, and, so far, no classical theories can explain consciousness in the brain. In light of this lack of understanding, some researchers ...
It's Easier to Observe the Failure of Local Realism than Previously Thought
Mar 04, 2009 |
4.3 / 5 (41) |
199
(PhysOrg.com) -- Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly ...
It's All Relative: UCSD's Einstein Robot Has 'Emotional Intelligence' (Video)
Feb 13, 2009 |
4.1 / 5 (10) |
6
(PhysOrg.com) -- Albert Einstein may have written his last scientific theory more than half a century ago, but he's still honing his emotional intelligence in a laboratory at the University of California, ...
Physicists Propose Method for Entangling Moving Material Particles
Jan 16, 2009 |
4.2 / 5 (16) |
14
(PhysOrg.com) -- When physicists experiment with quantum entanglement, they usually work with photons, the intangible particles of light. In the past few years, however, scientists have begun to broaden their ...
Physicists use Bose-Einstein condensates to enhance factoring algorithm
Nov 10, 2008 |
4.4 / 5 (54) |
11
(PhysOrg.com) -- Theoretically, quantum computing has the potential to work more efficiently and accurately than classical computing for certain processes, such as factoring. But quantum methods are experimentally ...
Gravity waves could hold key to supersymmetry
Nov 05, 2008 |
4.4 / 5 (59) |
11
(PhysOrg.com) -- "In Geneva," Anupam Mazumdar tells PhysOrg.com, "there is a big effort to discover supersymmetry particles at the Large Hadron Collider. But that is not the only way to find these particles. We should also b ...
