minus-squareAlwaysNowNeverNotMe@kbin.sociallinkfedilinkarrow-up2·2 年前This is acceleration with no mass and no resistance to medium.
minus-squareNeato@kbin.sociallinkfedilinkarrow-up12·2 年前Photons are born and die at c. They experience no time and have no frame of reference.
minus-squareAurenkin@sh.itjust.workslinkfedilinkEnglisharrow-up2·2 年前The speed of light is different depending on the medium though isn’t it? So to change speed I would have thought some acceleration would have to be involved. I have no idea what I’m talking about though.
minus-squareNeato@kbin.sociallinkfedilinkarrow-up2·2 年前It’s not. The wave front moves slower. Because when light moves through matter it’s getting absorbed and reradiated.
minus-squareAurenkin@sh.itjust.workslinkfedilinkEnglisharrow-up1·2 年前That’s neato, thanks for the science fact

The loneliest of experience.
