Speed of light. Speed of change.
Were physicists all wrong about the speed of light? You might think so, given the stories posted recently about a new paper suggesting that light travels a bit more slowly than the 186,000-miles-a-second figure that's familiar to generations of science geeks. "The speed of light has almost mythical significance in physics", Tyson told The Huffington…

Watch out for the assumptions...
A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere -- a key amplifier of global warming -- will intensify climate change impacts over the next decades. The new study is the first to show that…

Black holes. Magnetism. Fields.
A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched the force produced by the black holes' powerful gravitational pull. (1) Magnetic fields seem to be everywhere. It…

Pedestrians walking. Scientists analyzing.
The behavior of pedestrians can seem unpredictable — especially in a big crowd. Yet a group of scientists has developed an accurate mathematical representation of real-life pedestrian movement. By factoring in people’s ability to anticipate impending collisions, the researchers created simulations in which pedestrians naturally form lanes to walk in opposing directions and slow as…

Science describes. Nothing more.
A new type of quasar found, puzzles scientists since the current theories do not predict its existence. (1) The process of science adapting to experimental data is so fast that we hardly ever notice the fact that theory comes AFTER observations... Science is here to describe... Nothing more. All scientific models will always fit the…
