The Black Mesa facility is built over several decommissioned missile silo complexes constructed during the 1950s, which have been converted into a vast civilian institute for the research of scientific disciplines. Much of the work undertaken at the facility involves fairly practical scientific research, such as radiation, rocketry, theoretical physics, lasers, experimental propulsion, hydraulics, robotics, hydroelectricity, genetics, applied mathematics and a very wide spectrum of theoretical research into chemistry and all manner of physics research.
