Temperature Is A Measure of Mass per Volume

Present views of heat are that it is "the amount of energy flowing from one body of matter to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter."

However, the universe is infinite, as is shown here. What this means is that there are infinitely large and infinitely small masses within the universe. The force of gravity alone manipulates these systems into the universe as we see it. It is these infinitely small masses, the "infinitesimal", that determine large-scale observations when they work in conjunction with each other.

In reality, temperature is a measure of the amount of infinitesimal mass within a system. In other words, the infinitesimal mass per volume. Due to the relative mass of these infinitesimal particles, for a given observer, they are not seen as particles but instead become only measurable as temperature. Depending on the total mass of these particles, they produce a certain observed temperature in the overall systems.

When something is heated, there is an influx of infinitesimal mass into the system. This, in turn, causes the "temperature" to rise. One such particle is essentially irrelevant, but many such particles cause a large-scale observable change that we then compare to other systems and form a "temperature" scale from. The transfer of these infinitesimal masses from one system to another is what we call "heat exchange." As temperature increases, the internal pressure of these infinitesimal on one another also increases and so they tend to push each other apart. If the surroundings are a lower temperature, then they will physically push, due to this pressure, outward so that the heat then flows into the colder areas. This causes a balance of the infinitesimal mass per volume across a larger area so that equilibrium is reached between the initially hotter and colder regions, where there is a constant mass per volume of the infinitesimal masses in both systems and a shared temperature balance is reached. This internal pressure of the infinitesimal mass in a given system causes the larger particles, which we can more directly observe such as atoms, to gain increased kinetic energy because they are influenced by the pressures of the "ether" of infinitesimal particles, which is why atoms will move faster as they increase in temperature.

Thus, rather than entropy being the universe's tendency towards "chaos", it is just simply exchange of infinitesimal mass from one system to another. Even if it goes into the deepest, emptiest parts of what we observe in space, it will reach a steady-state. It will always be available to at some point be drawn by gravity to another system and re-merge with larger systems to become part of atoms, planets, stars, and so on once more. In this way, the universe is eternal. Energy is never lost, but rather changes "form" relative to a given observer. We are composed of atoms and this positions us in the cosmos in a very specific location where all adjacent relative levels are then observable as they are. This is only because we are composed of the arbitrary level we are on that we term "atoms". We could be composed of any building block, and the adjacent levels, then, would be our observed universe. The same observed universe where we would still consider our building blocks "atoms", and yet on a completely separate "dimension" in the universe.

Notably, it is directly dependent on the observer in how that mass is seen. Even the most infinitesimal of particles in our eyes is still infinite relative to smaller, and an observer composed of sufficiently small building blocks would be capable of seeing that infinitesimal mass as a planet, a star, a black hole, and beyond. All things are relative in this way and dependent on the observer's building blocks.

This is why it is impossible to reach Absolute Zero. Regardless of how much infinitesimal mass is stripped from a system, there is always another layer to be removed in the infinite layers of the universe.
