i scared somone recently... it's amazing how we just take things for granted. I explained to someone at work that no matter where you look you are looking into the past...
"
what! no way" came the exclamation.
the eye registers light and light travels at a finite speed so it would stand to reason that if you look at an object lightyears away or 4 meter the light still has to travel from the object to you eye...
I was working the lateshift with this person and the rest of the shift was spent in relative silence
yeah i know this is relatively basic stuff but its stuff the average person doesnt think about
