The Second Law of Thermodynamics

We know that Timemachine can not exist. The arrow of time shows the direction of the flow of time. Because of the irreversibility of nature, we can not go back to the past, only go to the future. Extending the concept of entropy to the limit leads to the conclusion of heat death. Heat death means the cosmic scale thermodynamic equilibrium. It means that the movement of heat is unable. At this moment, we can not observe any transition of heat. It means we can not define the arrow of time! Therefore heat death means the halt of time.

So the heat death hypothesis conflicts with the samsara. In the samsara worldview, the universe is beginningless and endless. There are two contradictions. First, if heat death is, it must have already happened. Because there is no traceable beginning in samsara. Second, if samsara is true, heat death can not occur in the future. Because the end of time is impossible.

I think this discrepancy arises because modern science does not set a hypothesis from the fact that the mind is ahead of the material. So the observation of time based on information about a matter may become useless in the future, but it does not mean the halt of time.

I contemplate this problem because I wonder what Dhamma explains about how we can know that time flows in one direction, from the past to the future. At least from what I have learned so far, the criterion will probably be whether the experience exists in Namagotta. But I’d like to hear some explanation better than this.
