minus-squareFaceDeer@kbin.sociallinkfedilinkarrow-up16·10 个月前Which is funny because that would have been even more inaccurate. “Millions of light years” is off by a factor of 15,000 or more. “Millions of miles” is off by a factor of 400,000,000 or more (2 million miles is 0.00000034 light years).

minus-squareSkybreakerEngineer@lemmy.worldlinkfedilinkEnglisharrow-up2·10 个月前You might think it’s a long way down the street to the chemists, bur that’s just peanuts to space
minus-squarepsychothumbs@lemmy.worldOPlinkfedilinkEnglisharrow-up5·10 个月前I guess you could argue it’s many many millions of miles, doesn’t have to exclude the total being in the billions, trillions or beyond. Though now I’m trying to think if there is any unit of measurement that it would be literal millions of away. Light seconds maybe?
minus-squareFaceDeer@kbin.sociallinkfedilinkarrow-up3·10 个月前There’s ~31 million seconds in a year, so that’s getting closer.
minus-squarepsychothumbs@lemmy.worldOPlinkfedilinkEnglisharrow-up5·10 个月前Hmm so that overshoots a little into billions of light seconds. I’ve got it: millions of light minutes away! (70ish million if my math is right)
