A space simulation toolkit is a collection of software libraries, assets, and engines designed to replicate the physics, environment, and scale of outer space. Unlike rigid commercial games, these toolkits offer programmable environments. Users can manipulate variables like gravity, mass, time dilation, and atmospheric drag to conduct experiments or build custom interactive applications.
