Experimental Quest to Test Einstein's Speed Limit
Special relativity states
that the speed of light is
the same in all frames of
reference and that nothing
can exceed that limit. UC
Berkeley physicists used a

Largest Magnetic Fields in the Universe
Numerical simulations show
for the first time the
occurrence of an instability
in the interior of neutron
stars that can lead to
gigantic magnetic fields,
possibly triggering one of

Behavior of Turbulent Flow of Superfluids Is Opposite That of Ordinary Fluids
A superfluid moves like a
completely frictionless
liquid, seemingly able to
propel itself without any
hindrance from gravity or

Space-Time Is Not the Same for Everyone
Before the Big Bang,
space-time as we know it did
not exist. So how was it
born? The process of
creating normal space-time
from an earlier state
dominated by quantum gravity

New Method Proposed for Detecting Gravitational Waves from Ends of Universe
May 16, 2013 — A new window into the nature of the universe may be possible with a device proposed by scientists that would detect elusive gravity waves from the other end of the ... > full story -
New Principle May Help Explain Why Nature Is Quantum
May 14, 2013 — Like small children, scientists are always asking the question 'Why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. ... > full story -
Einstein's Gravity Theory Passes Toughest Test Yet
April 25, 2013 — A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive ... > full story -
Light Bursts out of a Flying Mirror

Curtains Down for the Black Hole Firewall Paradox: Making Gravity Safe for Einstein Again
March 6, 2013 — Scientists have revealed new insights into the life and death of black holes. Their findings dispel the so-called firewall paradox which shocked the physics community when it was announced in 2012 ... > full story -
Particle Physics Research Sheds New Light on Possible 'Fifth Force of Nature'
February 21, 2013 — In a breakthrough for the field of particle physics, researchers have established new limits on what scientists call "long-range spin-spin interactions" between atomic particles. These interactions ... > full storyMore: -
Journey to the Limits of Space-Time: Black Hole Simulations on Supercomputers Present New View of Jets and Accretion Disks
February 21, 2013 — Black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy. In a recent article, researchers predicted the formation ... > full story -

Dark Energy Alternatives to Einstein Are Running out of Room
January 9, 2013 — Astronomers have found that a popular alternative to Albert Einstein's theory for the acceleration of the expansion of the universe does not fit newly obtained data on a fundamental constant, the ... > full story -
News from the World of Quantum Physics: A Non-Causal Quantum Eraser
January 9, 2013 — Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and ... > full story
