in another thread someone posted a video about the most important picture ever taken. it was a picture of galaxies 78 billion light years away.
a light year is the distance light travels in a year. light reaches earth in about 8 seconds from the sun. in 8 friccin seconds it travels 93 million miles!
now just for the sake of my stoned ass having to do hard math lets say it take 10 seconds. 10 goes into a min 6 times. a min goes into an hour 60 times. an hour goes into a day 24 times. a day goes into a year 365 times.
so 6 x 60 x 24 x 365= 3,153,600... 3,153,600 x 93 million(i sure as shit am not doin that math)
that means light travels 3,153,600 x 93 million miles in a year. now multiply that times 78 billion and that tells us how many miles away these galaxies are. farther than comprehendible.
ok so to the point. for us to take that picture the image would have had to travel that far. so in theory it would take forever for us to receive the image and now that galaxy could look completely different or even be nonexistent.
see while the image was traveling time keeps goin and things keep changing.
atleast thats my theory. wow i really hope someone feels me on this one lol
