Starlight

Light travels at 299792458m/s. So when we see starlight we are really seeing the past. That light was emitted minutes, maybe hours, countless days but probably years or even centuriesbefore (depending on how far away the star is) and has traveled distances we can't even dream of.

The funny thing is, that a star can die, but we can still be seeing its light long after. It's gone, but we can still benefit from its light.

It just shows how some things only touch us long after they're already gone.




This is such a wierd, wide, pointless idea. I might not look too much into it. Tomorrow I may actually make sense for once (probably not) oh well.

  1. as a matter of fact, the light from our closest star outside out galaxy (alpha centauri) takes 4 years and 3 months to get to us. Not a mear few days.

    1. Yes thankyou. I know that light from our sun takes only 8 minutes to reach us though. As I said, it depends which star you're looking at and how far away it is. I was really looking at the metaphorical resonance of goodness only taking effect on us some time after. Thankyou though :) Beth xx
