Physicist suggests speed of light might be slower than thought
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 ...
Discovery that quasars don't show time dilation mystifies astronomers
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 ...
Physicists extend special relativity beyond the speed of light
Atom smasher achieves 'Big Bang' collisions (Update)
Scientists at the world's biggest atom smasher on Tuesday started colliding particles at record energy levels, opening a new era in the quest for the universe's deepest secrets.
Speed-of-light 'nano-camera' produces 3D translucent objects
A $500 "nano-camera" that can operate at the speed of light has been developed by researchers in the MIT Media Lab.
Experiment with speeding ions verifies relativistic time dilation to new level of precision
Physicists find a new way to slow the speed of light
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.
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 ...
Ephemeral vacuum particles induce speed-of-light fluctuations
New research shows that the speed of light may not be fixed after all, but rather fluctuates.
Researchers create light from 'almost nothing'
Variables of nature
Within physics there are certain physical quantities that play a central role. These are things such as the mass of an electron, or the speed of light, or the universal constant of gravity. We aren't sure ...
