minus-squarecircuscritic@lemmy.calinkfedilinkEnglisharrow-up8arrow-down3·8 个月前No, it’s not slow, at all. It’s the speed of light. Unfortunately for us humans, we are a relatively fast form of life, when compared against the scale of our solar system, much less our galaxy, even when communicating at the speed of light.
