Albert Einstein's assertion that there's an ultimate speed limit – the speed of light – has withstood countless tests over the past 100 years, but that didn't stop University of California, Berkeley, postdoc Michael Hohensee and graduate student Nathan Leefer from checking whether some particles break this law.

I Love Q Formula Insights Into Universe
2013-07-26 11:51:21

The so-called 'I Love Q' equation that relates to neutron stars may offer surprising insights into the nature of the universe.

Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now.

Nature's Constants Not Constant
2013-07-05 08:29:31

Researchers recently studied a distant white dwarf star to measure the strength of the electromagnetic force, one of the four fundamental forces that shape the universe as we know it. They hoped to determine whether the laws of physics were constant throughout the universe.

Astronomers Use The Very Long Baseline Array To Set New Record
2013-06-13 14:46:36

An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from Earth.

Exchange of electromagnetic energy is fairly well understood. The force carrier, the photon, is readily detectable and manipulated, making the physics of electromagnetic radiation easy to study.

Cosmic Test Upholds Einstein's Theory Of General Relativity
2013-04-25 13:56:53

A team of researchers used telescopes around the world to study the most massive neutron star confirmed so far, orbited by a white dwarf. The scientists wrote in the journal Science that so far the new observations match up with Einstein's predictions for general relativity.

String Theory -- A string theory is a physical model whose fundamental building blocks are extended objects (strings, membranes and higher-dimensional objects) rather than points. String theories are able to avoid problems, such as infinite energy density, associated with the presence of mathematical points in a physical theory. The term 'string theory' properly refers to both the 26 dimensional bosonic string theories and to the 10 dimensional superstring theories discovered by...

Spacetime
2004-10-19 04:45:42

Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...
