Black Hole
Timeline (last 90 days)
The Birch Planet is an extreme megastructure concept proposed in science fiction and futurology, referring to an ultra-large habitation structure composed of multiple layers of orbital shells with a black hole as the gravitational anchor and energy core.
The efficiency of converting matter fed into a black hole into usable energy far exceeds that of fission or fusion, approaching the theoretical upper limit set by physics.
In some speculative models, the interior of a black hole may not terminate at a singularity but could instead be the birth of an entirely new expanding spacetime.
The black hole in the eternal solution differs from an astrophysical black hole formed by the actual collapse of a star; a real black hole does not come with a past white hole region.
A white hole is the time reversal of a black hole—a region of spacetime that nothing can enter but from which everything emerges.
Gravity produced by ordinary matter causes spacetime to collapse and contract, which is the mechanism behind black hole formation.
An overcount of quasars means that early black holes may have been overestimated.
