A spacecraft using the halo drive would be capable of accelerating to 133% of the speed of the black hole. This is true regardless of the mass of the spacecraft, so long as it is significantly less than the mass of the black hole. This means that the acceleration of very large spacecraft to relativistic speeds becomes feasible. [1] [2]
Black holes seem to have a sweet spot in terms of size, power and lifespan which is almost ideal. A black hole weighing 606,000 metric tons (6.06 × 10 8 kg) would have a Schwarzschild radius of 0.9 attometers (0.9 × 10 –18 m, or 9 × 10 –19 m), a power output of 160 petawatts (160 × 10 15 W, or 1.6 × 10 17 W), and a 3.5-year lifespan ...
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.
Tau Zero, a hard science fiction novel by Poul Anderson, has a spaceship using a constant acceleration drive. Spacecraft in Joe Haldeman's 1974 novel The Forever War make extensive use of constant acceleration; they require elaborate safety equipment to keep their occupants alive at high acceleration (up to 25 g), and accelerate at 1 g even ...
Warp drive, or a drive enabling space warp, is one of several ways of travelling through space found in science fiction. [3] It has been often discussed as being conceptually similar to hyperspace. [3] [4]: 238–239 A warp drive is a device that distorts the shape of the space-time continuum.
However, the merger of black holes is expected to occur during the collision of galaxies. [8] This unsolved problem is known as the final parsec problem. By finding and studying black holes less than 1 pc apart, ORBIS aims to resolve this issue. [8] Computer simulation of a binary black hole system
Some early "portal" appearances in science fiction include A. E. van Vogt's novella Secret Unattainable (July 1942, Astounding), [2] a radio episode of Space Patrol that aired October 25, 1952 (in which it was called a "cycloplex" or a "hole in space"), and Robert A. Heinlein's Tunnel in the Sky (1955) and its "Ramsbotham jump".
SAFER was co-invented by former astronauts Joseph Kerwin, Paul Cottingham and Ted Christian under a Lockheed contract to NASA for Space Station Freedom. [citation needed] It was later [when?] sponsored by the Space Shuttle Program and developed by Lockheed and NASA personnel. SAFER was the design solution to the Shuttle Program's requirement to ...
