It can look dumb, but I always had this question as a kid, what physical principles would prevent this?
minus-square@Aurora_TheFirstLight@lemmy.blahaj.zonelinkfedilink-2•2 months agoIirc from the 2 YouTube videos I watched light can theoretically bend thanks to gravity, black holes anyone?
minus-square@Longpork3@lemmy.nzlinkfedilink12•2 months agoSpace bends due to gravity. Light continues in a straight line through the now non-linear space, thus appearing to bend.
minus-square@Klear@lemmy.worldlinkfedilinkEnglish9•2 months agoGravity bends spacetime, light always goes in a straight line, bent spacetime means straight lines can be curvy. That all checks out. But none of that helps you with FTL communication.
