  2. Batteries in space - Wikipedia

    en.wikipedia.org/wiki/Batteries_in_space

    Batteries are used on spacecraft as a means of power storage. Primary batteries contain all their usable energy when assembled and can only be discharged. Secondary batteries can be recharged from some other energy source, such as solar panels or radioisotope-based power (), and can deliver power during periods when the space vehicle is out of direct sunlight.

    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 ...

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

    In the Known Space universe, constructed by Larry Niven, Earth uses constant acceleration drives in the form of Bussard ramjets to help colonize the nearest planetary systems. In the non-known space novel A World Out of Time, Jerome Branch Corbell (for himself), "takes" a ramjet to the Galactic Center and back in 150 years ships time (most of ...

    en.wikipedia.org/wiki/Spacecraft_design

    Spacecraft design is a process where systems engineering principles are systemically applied in order to construct complex vehicles for missions involving travel, operation or exploration in outer space. This design process produces the detailed design specifications, schematics, and plans for the spacecraft system, including comprehensive ...

    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
