Science tells us the universe is expanding and the stars and galaxies are moving away from each other at an unmeasureable rate. The photograpic images of all the stars and galaxies are a record of what was there in a long ago time equal to the objects distance away measured in light years, which is the distance light travels in one earth year. In other words if a star is 1000 light years away we're seeing the light and image of what the star looked like 1000 years ago, or if a galaxy is 20000 light years away we're actually seeing what it looked like twenty thousand years ago. If all these stellar objects are moving away from each other how do we know they're still there occupying that same area of space, or if they still exist at all? By this reckoning couldn't what we are seeing simply be the images of where a handful of galaxies were at various times and stages of their development, or even the footprints of just one galaxy's travels over billions and billions of years?
