I thought that I made it pretty clear that I know that time cannot run backwards. I can know it as an absolute fact because it is merely a logic issue.
Time, Distance, Mass, and Energy are things that cannot have a negative value except with respect to an arbitrarily chosen standard.
Time is the measure of change. There cannot be negative amount of change, only a negative-direction of change.
Distance is the measure of immediateness of spacial contact. There can be no negative immediateness of contact.
Mass is a measure of existence. There can be no negative existence.
Energy is the measure of ability to cause change. There can be no negative of the ability to cause change.
Each of those have a range of zero upward to more. None can have a negative, from zero to less than zero.
There cannot be a less than zero;
Change,
Immediateness of contact,
Existence, nor
Ability to cause change.
Reversal of time could be crudely simulated by reversing the direction of motion of some items of concern. A ball rolling “forward” could be reversed such as to roll “backward” instead. The spacial direction of motion, vector, can be reversed for specifically chosen objects. That would give the appearance of motion moving backward as long as someone knew of a “forward” with which to compare it. But it is limited to the chosen objects and their situation.
Time can be circled such as to advance objects in spacial directions that lead to their return to a prior state that can then be called “a state of history”. Chosen situations can be returned to a prior state. But their prior state cannot automatically advance to yet a pre-prior state in most cases due to the combinatorial effects of interaction.
Because there is no negative mass, there can be no negative gravity (mass and gravity being essentially the same thing). Thus an object such as a meteor being affected by gravity and striking the Earth could be given a reversed vector, but will not be able to find or maintain its prior course. The following situation cannot be reversed. Reflecting the photon will not cause the photon to reverse its path.
Logic is omnipresent and omnipotent. It applies to all of reality regardless of location. So you could be teleported 1000 trillion light-years away and logic would still apply and still demand all of the same “laws of physics”. A totally blind, deaf mute bestowed with logic and enough intelligence can discern the laws of physics without the slightest observation of them. If he was teleported far away and inside a steel vessel with no portals or outside measuring devices, he could still tell you a great many things that would necessarily be true about what was outside the vessel.
And that is the situation of every mind. It is inside a vessel from which it must deduce what is outside the vessel. The sensory ability it has merely reports on the current situation, not the eternal laws governing it. Those senses can be flawed and thus cause a misrepresentation of his current situation. But if his logic ability is not flawed, he will still know the laws of physics - “God is within you”, but cannot be seen, merely known.
The Gordian Knot can be untied from within. In the film The Matrix, the superhero, Neo working for the Zionists, defeated the evil System agents by revealing “the light of God” from within them, “The Light of Logic”.
