In other words, if time is only as determined as marbles going down the chute, then energy is enough to cancel some of the effects of time! Energy exists, so the only argument against free-will would be absolute lack of understanding, or a requirement for absolute energy, which is unreasonable. For example, wouldn't a small amount of energy determine the past, rather than the future? So, wouldn't a large amount of energy determine the distant past?
According to relativity, we have free will, and we are constantly transgressinng dimensions, because there is no other relation of past and future than arbitrating between larger and smaller amounts of energy.
