Physicists propose method to measure variations in the speed of light
Best of Last Week – speed of light may be wrong, fungus fights resistant bacteria and link between pesticides and autism
Engineers take big step toward using light instead of wires inside computers
(Phys.org)—Stanford engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead ...
Study finds single photons cannot exceed the speed of light
Goodbye Big Bang, hello black hole? A new theory of the universe's creation
Could the famed "Big Bang" theory need a revision? A group of theoretical physicists suppose the birth of the universe could have happened after a four-dimensional star collapsed into a black hole and ejected ...
Physicist suggests speed of light might be slower than thought
New analysis shows a way to self-propel subatomic particles
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
Physicists find a new way to slow the speed of light
How to test the twin paradox without using a spaceship
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin ...
New kind of cosmic flash may reveal something never seen before: Birth of a black hole
(Phys.org) —When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a ...
Experiment with speeding ions verifies relativistic time dilation to new level of precision
Testing Einstein's E=mc2 in outer space
(Phys.org)—University of Arizona physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be cor ...
Astronomers discover the largest structure in the universe
(Phys.org)—An international team of astronomers, led by academics from the University of Central Lancashire (UCLan), has found the largest known structure in the universe. The large quasar group (LQG) is ...
