Hi I'm 16 this is my first post here, something just struck me, I know nothing about physics and alot of things but I guess this is the right place to ask this kind of thing and I'm intrigued to know what peoples thoughts are on this.... If it takes 90% of estimated time to see the earliest observable galaxy, its next position in the sky, the galaxy should also project an image of it consisting of its light at a later time, this should cause it to create a streak of its own image across the sky, unless it was coming towards us or moving very jerkily and fast at intervals over long distances. These streaks would not necessarily be straight. These streaks would not be huge but enough to make the object untrue to its original shape or size. Which leads onto whether galaxies are actually moving away from each other, if they were surley this streak would be visible in a radial direction facing away from a certain point relying on the assumption there is a centre to the observable universe. I suppose this contradicts the big bang theory and the notion of the observable universe expanding but i just cant get my head round it.
