hypergravity
Beyond normal weight
Hypergravity is gravitational force exceeding Earth's standard gravity.
Scientists use centrifuges to simulate hypergravity for research on how increased gravitational stress affects organisms, materials, and physical processes: Astronauts train under hypergravity conditions.
The term appears in science fiction for planets with stronger gravitational pull than Earth.
