If you sit down and really try to wrap your head around how far a light day is, you'll quickly find it's such a mind-boggling distance that it defies your imagination.
Well, that's how far away Voyager 1 is from Earth, having passed that milestone earlier today after nearly half a century in space! And it's still partially operational, too. 🤯
@fasnix @ApostateEnglishman And when you have traveled for a whole year at light speed, you're still not gotten even close to anywhere.
On human time scales, the speed of light is stupidly slow.
