If the universe is eternal, then the universe would have already reached a metaphysically possible state for: (a.) a physical law to emerge or be realized that prescribes or describes that the universe enter a state of absolute stasis, where all future action is prohibited and the universe is compelled into complete immobility and unchangeability, or (b.) a meta-law or principle to emerge or be realized to prevent further changes to the physical laws while allowing changes to matter and energy.
A metaphysically possible state of the universe is one that is: (a) is not logically self-contradictory and (b) adheres to eternal or necessary truths (e.g., a triangle must have three sides and cannot have four).
The universe is not currently in a state of absolute stasis, and there is no convincing reason or scientific evidence to believe such a meta-law or principle exists.
Therefore, there is no convincing reason or scientific evidence to believe the universe is eternal. (modus tollens)
