    This animation shows two massive black holes in the OJ 287 galaxy. The smaller black hole orbits the larger one, which remains stationary in the animation and is surrounded by a disk of gas. When the smaller black hole crashes through the disk, it produces a flare brighter than 1 trillion stars. But the smaller black hole's orbit is elongated ...

  3. Alcubierre drive - Wikipedia

    en.wikipedia.org/wiki/Alcubierre_drive

    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.

  4. Black hole starship - Wikipedia

    en.wikipedia.org/wiki/Black_hole_starship

    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 ...

  7. Intergalactic travel - Wikipedia

    en.wikipedia.org/wiki/Intergalactic_travel

    There is no known way to create the space-distorting wave this concept needs to work, but the metrics of the equations comply with relativity and the limit of light speed. [ 9 ] A wormhole is a hypothetical tunnel through space-time that would allow instantaneous intergalactic travel to the most distant galaxies even billions of light years away.

  8. Cygnus X-1 - Wikipedia

    en.wikipedia.org/wiki/Cygnus_X-1

    Cygnus X-1 (abbreviated Cyg X-1) [11] is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole. [12] [13] It was discovered in 1964 during a rocket flight and is one of the strongest X-ray sources detectable from Earth, producing a peak X-ray flux density of 2.3 × 10 −23 W/(m 2 ⋅Hz) (2.3 × 10 3 jansky).

  9. Space travel under constant acceleration - Wikipedia

    en.wikipedia.org/wiki/Space_travel_under...

    Clarke's novel "Imperial Earth" features an "asymptotic drive", which utilises a microscopic black hole and hydrogen propellant, to achieve a similar acceleration travelling from Titan to Earth. The UET and Hidden Worlds spaceships of F.M. Busby 's Rissa Kerguelen saga utilize a constant acceleration drive that can accelerate at 1 g or even a ...
