Is it not true that out of all the items you've listed, none actually has a will of its own. Neither atoms nor galaxies can move, exist or demonstrate any will of their own. They must obey physical laws while we, on the other hand, do have free will insofar as determining our actions. It can be said we have restraints on our actions of various kinds, but few of those restraints are set in concrete, so to speak. i.e., there was a time not so distant past that man believed he could never travel to the Moon, but, voila! Yet a star cannot, of it's will, move from its galaxy to another, since it has no will, being an inanimate object.
Tell me once again how you intend to attach time travel cameras...
