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 ...
Blue Origin's famed New Shepard spacecraft successfully simulated the moon's low gravity on board its capsule during a brief flight Tuesday morning over West Texas.. Video of the uncrewed launch ...
The uncrewed Starship spacecraft was apparently destroyed during its first flight launch of 2025 that blasted off from south Texas. SpaceX's Starship spacecraft is apparently destroyed after ...
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
Supermassive black holes sometimes shoot vast jets of high-energy particles into space, but no such jet has been detected in this instance, according to astrophysicist and study co-author Lorena ...
