Calculations of non interventions or replenishment is the thinking of the atheistic Darwinian who are convinced of scientific materialism…

They say ..
“High entropy, driven by the second law of thermodynamics, leads to a “heat death” (or Big Freeze), where the universe reaches maximum disorder and becomes cold, dark, and empty. As energy spreads evenly, no further work can be done. Accelerated expansion ensures this, dispersing all matter and energy, leaving only a cold, thin haze of photons and decaying matter. “

But within the cell there is high entropy but also an ordered low entropy, order and tidiness is seen in the microbial world and through out the universe, nothing is in disorder , if there appears disorder its under the control of the order .
The multidimensional universe alongside dark matter and dark energies are a complete unknown to those who advocate the heat death hypothesis, like the Darwinian hypothesis is guessing and making conclusions that go against the objective grain , likewise heatdeath.

Although everything in the universe is created , maintained, and destroyed, including the universe one should refer to the Vedas about how the collapse of the universe takes place and how everything is brought back inside Karanadaksyi Visnu before again being let loose .
