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.
Rotating wheel space station. Wernher von Braun 1952 concept. A rotating wheel space station, also known as a von Braun wheel, is a concept for a hypothetical wheel-shaped space station. Originally proposed by Konstantin Tsiolkovsky in 1903, [1] the idea was expanded by Herman Potočnik in 1929, [2] and popularized by Wernher von Braun in 1952. [3]
The spacecraft of George O. Smith's Venus Equilateral stories are all constant acceleration ships. Normal acceleration is 1 g , but in "The External Triangle" it is mentioned that accelerations of up to 5 g are possible if the crew is drugged with gravanol [ 11 ] to counteract the effects of the g -load.
The 1999 television series Cowboy Bebop, a rotating ring in the Bebop spacecraft creates artificial gravity throughout the spacecraft. In the novel The Martian, the Hermes spacecraft achieves artificial gravity by design; it employs a ringed structure, at whose periphery forces around 40% of Earth's gravity are experienced, similar to Mars ...
Magnetic sail animation. A magnetic sail is a proposed method of spacecraft propulsion where an onboard magnetic field source interacts with a plasma wind (e.g., the solar wind) to form an artificial magnetosphere (similar to Earth's magnetosphere) that acts as a sail, transferring force from the wind to the spacecraft requiring little to no propellant as detailed for each proposed magnetic ...
In the Star Trek universe, the Romulan D'deridex-class warbird uses an artificial quantum singularity as a power source for its warp propulsion drive. In the 1997 Paul W. S. Anderson science fiction horror film Event Horizon , the eponymous starship uses an artificial black hole drive to achieve faster-than-light travel .
The 2024 Nobel Prize in physics has been awarded to John Hopfield and Geoffrey Hinton for their fundamental discoveries in machine learning, which paved the way for how artificial intelligence is ...
Now, if a fragile thread is tied between B and C, it's not long enough anymore due to length contractions, thus it will break. He concluded that "the artificial prevention of the natural contraction imposes intolerable stress". [2] Bell reported that he encountered much skepticism from "a distinguished experimentalist" when he presented the ...
