It can look dumb, but I always had this question as a kid, what physical principles would prevent this?

minus-square@[email protected]linkfedilink11•11 hours agoSpace bends due to gravity. Light continues in a straight line through the now non-linear space, thus appearing to bend.
minus-square@KlearlinkEnglish8•11 hours 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.
