Scientists work out how create matter from light, to finally prove Einstein's E=mc2 - ExtremeTech. Physicists in England claim they have discovered how to create matter from light, by smashing together individual massless photons– a feat that was first theorized back in 1934, and has been considered practically impossible until now.
If this new discovery pans out, the final piece of the physics jigsaw puzzle that describes how light and matter interact would be complete. Scientists discover how to turn light into matter after 80-year quest. Imperial College London physicists have discovered how to create matter from light - a feat thought impossible when the idea was first theorised 80 years ago.
In just one day over several cups of coffee in a tiny office in Imperial's Blackett Physics Laboratory, three physicists worked out a relatively simple way to physically prove a theory first devised by scientists Breit and Wheeler in 1934. Breit and Wheeler suggested that it should be possible to turn light into matter by smashing together only two particles of light (photons), to create an electron and a positron – the simplest method of turning light into matter ever predicted. The calculation was found to be theoretically sound but Breit and Wheeler said that they never expected anybody to physically demonstrate their prediction. It has never been observed in the laboratory and past experiments to test it have required the addition of massive high-energy particles.

Moon encylopiedia. Essential question research. Deep Space Industries. Deep Space Industries, or DSI, is an American privately-held company with global operations, operating in the space technology and resources sectors.
The company is developing spacecraft technologies that are needed for asteroid mining, and is currently selling satellites that use these technologies. DSI is expecting to make in-space materials, extracted from asteroids, commercially available in the early 2020s, include space-based refueling, power, asteroid processing, and manufacturing. History DSI was formally announced on January 22, 2013 and currently has three spacecraft and patent-pending microgravity manufacturing technologies under development. According to David Gump, founding CEO, speaking at the company's launch in Santa Monica, California, another early goal of the company is to refuel communications satellites that contain a refueling interface.

Variable Specific Impulse Magnetoplasma Rocket. Artist's impression of multi-megawatt VASIMR spacecraft VASIMRs units for development and test have been assembled by the Ad Astra Rocket Company, headquartered in the city of Houston, Texas, United States. Design and operation The Variable Specific Impulse Magnetoplasma Rocket, sometimes referred to as the Electro-thermal Plasma Thruster or Electro-thermal Magnetoplasma Rocket, uses radio waves to ionize and heat propellant, which generates plasma that is accelerated using magnetic fields to generate thrust.
Electrically powered spacecraft propulsion. For vehicles other than spacecraft that are propelled by electric means, see Electric vehicle.
An electrically powered spacecraft propulsion system uses electrical energy to change the velocity of a spacecraft. Most of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed, but electrodynamic tethers work by interacting with a planet's magnetic field. Ion thruster. NASA's 2.3 kW NSTAR ion thruster for the Deep Space 1 spacecraft during a hot fire test at the Jet Propulsion Laboratory Ion thrusters are categorized by how they accelerate the ions, using either electrostatic or electromagnetic force.
Electrostatic thrusters use the Coulomb force and accelerate the ions in the direction of the electric field. Moon. The Moon is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters.
It is the second-brightest regularly visible celestial object in Earth's sky after the Sun, as measured by illuminance on Earth's surface. Its surface is actually dark (although it can appear a very bright white) with a reflectance just slightly higher than that of worn asphalt. Molybdenum. Molybdenum is a chemical element with symbol Mo and atomic number 42.
The name is from Neo-Latin molybdaenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. Eclipse. Totality during the 1999 solar eclipse.
Solar prominences can be seen along the limb (in red) as well as extensive coronal filaments. The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon.
A binary star system can also produce eclipses if the plane of the orbit of its constituent stars intersects the observer's position.
