    Distance Travelled by Light in One Year.
    Recent FermiLab Video on Photons got me Confused about this. 😅

    That fact used to be taught in 8th grade general science classes.

      I saw a new release movie recently and they still had it wrong in that movie! I then realized I did not have a video on it. So glad it is taught somewhere in 8th grade science class; it makes me wonder if the actors did not pass that class :)

      @astropictionary3988 When I taught second grade, we'd talk about how far the sun was from earth. Huge numbers mean nothing to little guys, so I'd set a timer for 8 minutes. We'd work with the flannelboard planets and when the alarm went off I'd tell them that was how long it took for the light to travel from the sun to the tip of your nose. They'd look around the room. There's lots of sun, then, one or two of the more adventurous ones would say. I'd answer, that there was more than they could imagine. There was always one who'd want to know if the sun would run out of light. Not for about 4 or 5 billion years. Is that a long time? Longer than you could imagine. The wonder in their eyes could make you weep.
