Sebuah asumsi yang luas dipegang dalam dunia teknik kini telah ditantang. Gagasan bahwa permukaan yang lebih halus selalu menghasilkan hambatan aerodinamis yang lebih kecil ternyata tidak berlaku dalam setiap kasus.
Hambatan aerodinamis menciptakan rintangan utama bagi kendaraan yang dirancang untuk melaju dengan kecepatan tinggi. Hal ini berlaku sama baik untuk pesawat terbang, mobil, maupun kereta cepat.
Researchers have found a way to alter the direction of energy flow in turbulence, challenging a theory established in 1941. The work, conducted at the University of Pittsburgh with Italian collaborators, was published in Science Advances in 2025.

Researchers have developed minuscule devices that use light to control movement in multiple directions, advancing the potential for light-powered spacecraft. The metajets, made from silicon, were tested in a lab setting and showed promising results for steering large sails through space. This breakthrough could help overcome current limitations in directing such vessels over vast distances.
