However, scientists from the Georgia Institute of Technology (Georgia Tech) have now proven the opposite – when bodies exist in curved spaces, it turns out that they can in fact move without pushing against something.These findings were published on July 28, 2022, in Proceedings of the National Academy of Sciences.“We let our shape-changing object move on the simplest curved space, a sphere, to systematically study the motion in curved space,” said Rocklin.The scientists set out to study how an object moved within a curved space.
They needed to confine the object on the sphere with minimal interaction or exchange of momentum with the environment in the curved space.
The research provides an important demonstration of how curved spaces can be attained and how it fundamentally challenges physical laws and intuition designed for flat space.
Rocklin hopes the experimental techniques developed will allow other researchers to explore these curved spaces.
Ultimately, the principles of how a space’s curvature can be harnessed for locomotion may allow spacecraft to navigate the highly curved space around a black hole.Reference: “Locomotion without force, and impulse via dissipation: Robotic swimming in curved space via geometric phase” by Shengkai Li, Tianyu Wang, Velin H.
