The entropy the Sandcastle expressed indicated its unavailability to participate for very long, knowing its existence in that state is temporary. It will then echo into an afterlife full of antimatter enabling its continued existence. Every previous interaction between particles observed has never created or destroyed a single particle of matter without also creating or destroying an equal number. The physical symmetry seems impossible but the only way any amount of matter has been changed in the Universe has been to also change the Universe’s antimatter by an equal amount.

It is said that entropy always increases because it is more likely that it will, and with the increase comes the explanation of why time only roams in one direction. This also accounts for the irreversibility of natural processes, as they will always arrive at a state of equilibrium.
Is this the true explanation of its continued existence into the afterlife? Or could it be this is just its current place on one of the many simulated infinite Universes? When the Universe is perceived to be real and material, it doesn’t mean that it is so.

“Reality is what we take to be true. What we take to be true is what we believe. What we believe is based upon our perceptions. What we perceive depends on what we look for. What we look for depends on what we think. What we think depends on what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. What we take to be true is our reality.” – David Bohm (theoretical physicist).
