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
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.
Physicists extend special relativity beyond the speed of light
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.
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'
Gamma-ray photon race ends in dead heat; Einstein wins this round
Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish ...
Light particles illuminate the vacuum
Researchers from the Finnish Aalto University and the Technical Research Centre of Finland succeeded in showing experimentally that vacuum has properties not previously observed. According to the laws of ...
A hint of Higgs: An update from the LHC
The physics world was abuzz with some tantalizing news a couple of weeks ago. At a meeting of the European Physical Society in Grenoble, France, physicists -- including some from Caltech -- announced that ...
Einstein was right, neutrino researchers admit
Scientists on Friday said that an experiment which challenged Einstein's theory on the speed of light had been flawed and that sub-atomic particles -- like everything else -- are indeed bound by the universe's ...
Large Hadron Collider gains pace: CERN
The world's biggest atom smasher is swiftly gaining pace as scientists seek to unravel the secrets of the universe, the European Organisation for Nuclear Research (CERN) said on Monday.
Faster than light neutrinos? More like faulty wiring
You can shelf your designs for a warp drive engine (for now) and put the DeLorean back in the garage; it turns out neutrinos may not have broken any cosmic speed limits after all.
'Faster-than-light' particles fade after cross-check
Neutrinos do not go faster than light, according to fresh measurements of a test last year that had suggested the particles broke the Universe's speed limit, CERN said on Friday.
