![]() Unfortunately, despite it having all the hallmarks of a great arcade experience, Curved Space felt like it was lacking something.Ĭurved Space is an arcade twin stick shoot ‘em up with a twist: you pilot your craft along the surface of objects in a gravity defying way. When I first saw the trailer for Curved Space I knew it was something I wanted to try. Neon lights and pounding music remind me of standing in front of arcade cabinets, gleefully shoving in quarter after quarter as I got pummeled by pixelated threats. ![]() Evrim Yazgin has a Bachelor of Science majoring in mathematical physics and a Master of Science in physics, both from the University of Melbourne.There’s a place deep in my psyche that responds with childlike glee at the sight of arcade shooters. This article was originally published on Cosmos Magazine and was written by Evrim Yazgin. That engine was indeed impossible, but because spacetime is very slightly curved, a device could actually move forward without any external forces or emitting a propellant – a novel discovery.” “Its creator claimed that it could move forward without any propellant. “This research also relates to the ‘Impossible Engine’ study,” says Rocklin. ![]() The principles of how the curvature of space can be harnessed for locomotion may ultimately be useful in circumnavigating the highly curved space around black holes. Similar to how slight changes in the frequency of light due to gravity became crucial to GPS navigation, the team expects their findings and future findings in curved-space dynamics will be applicable in engineering. While the observed effects due to curved space are small, the researchers believe that increasingly precise robotics will see these curvature-induced effects having practical applications. Rocklin hopes the methods used will allow further experimental investigations of curved space. So, the team demonstrated not only how curved space can be realised, but also how it fundamentally challenges basic concepts attributed to the laws of flat space. The robot felt only slight forces due to friction and gravity, but the two effects were seen to hybridise with the curvature of the space itself to produce a strange dynamic with properties which could not have been produced by either friction or gravity on their own. Gravity was diminished by aligning the rotating shaft with Earth’s gravity. The tracks were then attached to a rotating shaft to produce a spherical space.įriction was curtailed using air bearings and bushings – low heat and low mess alternatives to ball bearings. The curved space was produced by placing a set of motors drive on curved tracks. Only then could the team ensure minimal interaction or exchange of momentum with the environment. To make sure that the effects induced by the curvature of the robot’s space dominated, the physicists had to isolate the system as much as possible from external forces. “We learned that the predicted effect, which was so counter-intuitive it was dismissed by some physicists, indeed occurred: as the robot changed its shape, it inched forward around the sphere in a way that could not be attributed to environmental interactions.” “We let our shape-changing object move on the simplest curved space, a sphere, to systematically study the motion in curved space,” says lead researcher Zeb Rocklin, assistant professor in the School of Physics at Georgia Tech. Without friction (or with minimal friction, for example, when there is a slimy banana peel on the ground) there is no push – we just slide straight over the ground and can’t move forward, falling unceremoniously back to Earth. So, when a human takes a step, we push against the Earth and the Earth pushes back, propelling us forward. Newton’s third law states that for every action there is an equal and opposite reaction. It may not seem like it, but the quip relies on the fact that human locomotion, like all locomotion, is based on Newton’s third law of motion. We’ve all seen the hilarious slapstick gag where the unwitting individual steps on a banana peel, landing comically on their rump. Such new principles may have applications in new forms of locomotion without propellants. Byron Echo Print Archive (previous volume)Ī robot engineered at Georgia Institute of Technology (Georgia Tech) has done the unthinkable and flouted a steadfast law of motion, suggesting that new laws need to be defined.
