    Anyone noticed the speed of light has changed too?

    When I was at school I`m sure the speed of light was about 186234 miles per second, now its quite a few miles faster.

    So light has speeded up during my lifetime (or they just measure it a bit cleverer these days?)


    When I was at school the speed of light was 186,282.39 miles per second (plus or minus about 0.4 miles per second) so does that make me younger than you? I think the speed of light is constant, but they have always been saying that with advances in technology distances are shrinking, so perhaps the miles are shorter.




    186,282.397 miles/sec. I remember that being given in a science programme on TV late 70s early 80s (BBC Horizon?). Apparently they got it by comparing two laser beams.
