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 ...
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]
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 ...
The high voltage pulses would travel along the spacecraft's exterior cables and end the mission. Too late to cancel the mission or divert the probes there was no time to go through “normal ...
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 blanet is a member of a hypothetical class of exoplanets that directly orbit black holes. [1]Blanets are fundamentally similar to other planets; they have enough mass to be rounded by their own gravity, but are not massive enough to start thermonuclear fusion and become stars.
A gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense.
Superluminal motion is most often observed in two opposing jets emanating from the core of a star or black hole. In this case, one jet is moving away from and one towards the Earth. If Doppler shifts are observed in both sources, the velocity and the distance can be determined independently of other observations.
