Geometry of Spacetime as a Quantum Information Processing Device
In the race for building a scalable quantum computer, devices using photons as carrier of quantum information are in the front run. The reason is the easiness… Read more “Geometry of Spacetime as a Quantum Information Processing Device”
A Sad Day For The Scientific Community – Stephen Hawking Passes Away
Science’s brightest star has passed away aged 76. A physicist and best-selling author, Dr. Hawking did not allow his physical limitations to hinder his quest to answer “the… Read more “A Sad Day For The Scientific Community – Stephen Hawking Passes Away”
What Are Gravitational Waves?
Gravitational waves are ripples in space-time (the fabled “fabric” of the Universe) caused by massive objects moving with violent accelerations (in outer space that means objects like… Read more “What Are Gravitational Waves?”
Exoplanet WASP 12-B Is So Hot It Eats Light
NASA’s Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it… Read more “Exoplanet WASP 12-B Is So Hot It Eats Light”
Accretion-powered pulsar reveals unique timing glitch
The discovery of the largest timing irregularity yet observed in a pulsar is the first confirmation that pulsars in binary systems exhibit the strange phenomenon known as… Read more “Accretion-powered pulsar reveals unique timing glitch”
The Mystery of High-Energy Cosmic Rays
Hold out your hand for 10 seconds. A dozen electrons and muons just zipped unfelt through your palm. The ghostly particles are what scientists call “secondary cosmic… Read more “The Mystery of High-Energy Cosmic Rays”
20 Facts About the Big Bang
Modern cosmology has its roots in the 1920s when physicists were starting to get to grips with relativity theory. Calculation of solutions to relativity was producing some… Read more “20 Facts About the Big Bang”
Astronomers may have seen a star collapse directly to a black hole
One of the basic truisms in astronomy is that, when a massive star ends its life, it goes out with a bang. A big one. A supernova.… Read more “Astronomers may have seen a star collapse directly to a black hole”
Cassini probe shoots through Saturn’s rings
NASA’s Cassini spacecraft has successfully executed its daring dive through the 1,500-mile-wide gap between Saturn and its rings, the first time a man-made object has navigated through… Read more “Cassini probe shoots through Saturn’s rings”
Black Hole Swallowing a Star Mistaken for Brightest Supernova
The universe’s brightest supernova ever may be something far more rare. An extraordinary display of light in a distant galaxy that had been previously dubbed brightest supernova… Read more “Black Hole Swallowing a Star Mistaken for Brightest Supernova”
Supernovae showered Earth with radioactive debris
An international team of scientists has found evidence of a series of massive supernova explosions near our solar system, which showered the Earth with radioactive debris. The… Read more “Supernovae showered Earth with radioactive debris”
