Evening geofag here. Well the assumption of nothing or everything is moot as it is before any 4D and can be interpreted as one or both. Time is motion and is defined by the relative speed of observers traditionally. In timeline theory or 5D time all happens at once and can be perceived from beginning to end; and only timeline changes with different choices (that is a higher D where all timelines are observed).
one of those paths is a Path towards The Truth,
"if x does not change between two consecutive timesteps - all time derivatives of x are 0 at that particular t" That is quantum wave basically - all options exist in the quantum wave and once a choice or observation/return is made all other previous timeline possibilities cease to exist for that perception. The truth or lies thing goes more to philosophy and the vibrational frequency or total energy of defined set.
