The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
A reactionless drive is a hypothetical device producing motion without the exhaust of a propellant.A propellantless drive is not necessarily reactionless when it constitutes an open system interacting with external fields; but a reactionless drive is a particular case of a propellantless drive that is a closed system, presumably in contradiction with the law of conservation of momentum.
White attracted the attention of the press when he began presenting his ideas at space conventions and publishing proposals for Alcubierre drive concepts. In 2011, he released a paper titled Warp Field Mechanics 101 that outlined an updated concept of Miguel Alcubierre's faster-than-light propulsion concept, including methods to prove the feasibility of the project.
Space travel also happens to be a great business opportunity. Helping power Europa Clipper into space was a SpaceX Falcon Heavy rocket. Elon Musk's company has won plenty of government contracts, ...
The Bussard ramjet is a theoretical method of spacecraft propulsion for interstellar travel.A fast moving spacecraft scoops up hydrogen from the interstellar medium using an enormous funnel-shaped magnetic field (ranging from kilometers to many thousands of kilometers in diameter); the hydrogen is compressed until thermonuclear fusion occurs, which provides thrust to counter the drag created ...
AST SpaceMobile made history in April 2023 by completing the first two-way phone call via space on an unmodified cell phone. This milestone was achieved using its low Earth orbit satellite, Blue ...
Timelapse satellite video taken from space shows the rapid expansion of the California wildfires, offering a harrowing look at how quickly the blazes exploded over the last two days amid powerful ...
