بادبان های خورشیدی بین ستاره ای با 75 درصد سرعت نور به مشکل عجیبی برخورد کردند

Interstellar solar sails hit a strange problem at 75% of light speed

Solar sails pushed by powerful lasers could reach incredible speeds, but relativity may eventually make the light itself work against them. At around 75% of the speed of light, scattered photons can begin creating drag, adding a surprising obstacle to interstellar travel.
