This about my own personal belief. As a result, it will not be a finished project, as belief will always be a work in progress. It will not be coherent, as belief is not a scientific process. It will also not be flawless. Now that I have warned you against this, time to begin.
I believe in energy. As science has taught us, energy cannot be created or destroyed, it can just be transferred or changed. As a result of this, the amount of energy in the universe is fixed. There is only so much of it to go around. Think of this amount of energy as a great pool or ocean, deep and fathomless, but not infinite. This is what we have to begin with, and to end with.
Now remember that Earth has different oceans, each a different size and with differing characteristics. Think of the galaxies within the universe as these differing oceans. Each has an allocation of the total energy of the universe held within it, but it is not held solely within it. The water/energy from one can mix or fall into the other. Nothing is truly separate from each other.
This splitting up occurs again and again. Each galaxy has solar systems within it, which get an allocation of the energy of the galaxy, and each planet gets an allocation of the energy of the solar system. Every form of life gets a portion of the energy that is allocated to its planet. This is what I like to call our lifeforce. It is what connects us to everything.
It is a result of this allocation that species die out. A planet cannot support too much life. Its energy will get depleted through providing for life, and not for sustaining the life. I know I mentioned that energy can be transferred within the system, but it is not an easy process, and no matter how much water you pour into a cup, if it is full, it is full. As one species grows larger and more numerous, other species will start to die out. Their vital energy is diverted to the dominant species. Even if the species does not die out, this diversion of their energy damages the remaining members.
Now to leave pseudo-science behind. This energy that we are given at birth is limited, unless we attempt to steal if from others. When we are born, we are given our portion of energy from our pool, and when we die, the energy is given back to the pool to replenish it and be recycled. However, this energy can be changed slightly. Through our life, we imprint upon the energy, guide it towards certain acts and beliefs. When we die, the energy is put back into the pool, and these characteristics scattered, but they are not lost. They are simply diffused. If there is a consistent characteristic being pushed, it starts to get stronger and more prevalent. Obviously this can be for good or evil. To use the movie Gladiator, “What we do in life echoes in eternity.” This cannot be more true where, upon death, you are giving all that you have done, for good or bad, to the next generation.
I guess this is where I’ll end for today. It may not be the best theory/belief, but it is mine. It is the one that comforts me and is understandable to me. So yeah. As always, up for commentary.
Be safe. Be strong.
