i appolagise for any spelling/grammar mistakes, had to get it down before i forgot.
i was at work today and my mind starting wondering, as it usually does. for some reason i was thinking about the speed of light, i think i got there
by first thinking about space travel, but anyway, i digress...
i was thinkning about the staement that nothing can travel faster than the speed of light, and then i got to thinking about how we measure speed and
something hit me, the speed at which something is travelling is relative the the person taking the measurement.
im sitting in my car - the distance between me and my car is closing at a rate of 0mph, im moving 0mph
im driving to work - the distance between my car and work is closing at a rate of 40mph, im moving 40mph
both my car and my work are on earth - the earth is circling the sun at about 66,648mph, im moving 66,688mph
our solar system is orbiting a blackhole at the center of our galaxy
our galaxy is in and expanding universe........ you get were im going with this
how fast i am moving is entirely dependent on where you are taking the measurements from.
so if we say that speed is relative to the observer then how can we observe the speed of light from a truely stationary position?
also, wouldnt our measurement of the speed of light change depending on if we were moving away from or towards the source of said light?
let me chuck a quick hypathetical question at you (assuming i get more than just one or two visitor to this particular thread)
lets say that we are travelling on a ship, at the speed of light (hypathetical remember), if we were travelling away from a light source at the speed
of light then the distance between us and the photons travelling through space would not change, so that light would appear to be stationary.
on the flip side, if we were travelling towards a light source at the speed of light then the distance between us and the photons travelling through
space would close at twice the normal rate, so that light would appear to be travelling at twice the 'speed of light'.
so, in conclusion, if speed is relative to the observer, the speed of light cannot be pinned down as 299 792 458 m / s
what are everyones thoughts on this, or did i just write down a load of nonsense, i swear it made sense in my head.
