There is a solid scientific argument, for a possible free energy matrix, that can be used for an afterlife.
Proof for a possible realm connected to the afterlife.
The second law of Thermodynamics states that the entropy of the universe has to increase. This is one of the few laws in science, with any law higher than any theory. The 2nd law of science implies change is inevitable. Climate change is partially based on entropy and entropy having to increase. Entropy increasing in the universe; 2nd law, means reality, in all its many forms, become more and more complex. Entropy increase assures change over time. Even when making widgets on an assembly line, small defects can appear, to increase entropy. This makes life more complicated for engineers.
When entropy increases, free energy is absorb; lowers local free energy. Since the entropy of the universe has to always net increase, and energy will be absorbed, the logical result is the universe is bleeding energy into the 2nd law entropy increase; universe is losing useable free energy. The energy is conserved, but made net unusable to the universe, since net entropy has to always net increase; 2nd law. This pool of lost energy keeps getting larger and larger, even if some is recycled. We can reverse entropy, but this adds to the entropy increase or it would be called perpetual motion. This ever growing pool of entropic energy, separated from the material universe, is the most logical place for an afterlife.
The reason this pool should logically be connected to human and even animal after life, is our brain and consciousness function via changes in ionic entropy. The brain expends 90% of its metabolic energy pumping and exchanging ions in a way that lowers ionic entropic. Lot of energy is used by the brain to go against the 2nd law, at the cost of 90% its metabolic energy. Consciousness is connected to the 2nd law acting on this added entropic potential as well as on its own.
Our memory, naturally gets more and more complex with added data and increasing data organization as we learn and age; wisdom of old age. Theoretically, our memory, due the entropic connection, should be adding to the pool of lost energy, due to the 2nd law. Our lifetime contribution to the pool is called our soul; our catalog of entropic parallel; memory, goes into the energy/entropy states within the pool.
There is conservation of energy. Even though energy is removed from the universe; universe ages as entropy increases and withdraw energy, the energy in the pool is still conserved. It is separate from the material universe; within another realm associated with entropic potential. The endothermic affect of an entropic increase; cooling, may be why parapsychology often feels cold zones, when it assumes that spirits/ghosts of the dead are present.
Religions, from all time, use(d) the brain to generate memory of an afterlife. These specific images of the after life, via entropy change due neuron firing, still represent an entropy increase. This sort of becomes a self fulfilling prophesy, since even imaginary, still involves neuron entropy increase, with specific afterlife imagery saved in the pool. The Christians, for example, have a very well defined place to enter into the other realm, based 20 centuries of collective neural entropic energy generation; specific pool zone of collective entropic addition that looks their paradise.
Based on entropy, even Atheists will have an entropic based afterlife since their neurons also increase entropy. The difference is many may end up alone, since Atheists expect there to being nothing, for an after life. They may sleep and dream since this is what they collectively expect. Other religions will have their own collective capacitance of neuron and entropic memories. The East may their version of paradise connected to a number of afterlife scenarios to forward integrate saved memory. It may take billions of human inputting to generate a collective safe zone.
