Creating Artificial Gravity Through Acceleration
- To create artificial gravity, a force must be generated, requiring flaws on a ship to be perpendicular to the direction of acceleration, akin to a building on its side moving through space.
- The sensation of acceleration and deceleration in a lift or elevator mirrors the force of acceleration and lightness experienced in generating artificial gravity.
- Gravity, as described by Einstein, is not a force but an acceleration caused by massive objects curving space-time, leading to the possibility of generating artificial gravity through acceleration.
- The show "The Expanse" delves into the scientific accuracy of generating artificial gravity, a detail appreciated by those well-versed in physics, distinguishing it from typical sci-fi tropes.
