Entropy always increasing?

Recently I saw some dust. They were cluttered together so I could simply pick them up and remove them. Then, I started thinking. Scientists say that in a closed area, entropy remains the same or increases but can never decrease. Is this really so?


In my case with the dust: after cleaning my house, my house smells fresh and is a little shiny; entropy is low but will soon (immediate) start to increase again. Dust will appear originating from e.g. clothes, and after a few days it is impossible to see I cleaned my house; it simply looks clean. After more time more dust is made, and people start seeing that the house is dirty, I should start cleaning again. Entropy is at its greatest and energy is needed to tidy again.

However, from a certain moment onwards, I think entropy reached its maximum and will decrease again until a certain level where a steady state arrives, and this because everywhere there is energy that stops the increase in energy. In some areas dust will stick together, while there will be less dust in certain other areas. Where dust settles, and forms clumps, entropy is also less as they form quite strong clusters that can be easily removed by picking up. So, even when nothing is cleaned and removed, overall entropy in the room is decreased.

This can now be extrapolated to live. The appearance of multicellular organisms was a normal evolution. In the beginning of life, only single organisms (let's say bacteria) lived and they multiplied and were scattered all over the oceans. But, many of these organisms where driven in certain directions by certain forces (e.g. currents), and at certain places the concentration of these bacteria increased dramatically and they were forced to live together while at other places the concentration decreased. After some time (millions of years) they started developing symbiosis (otherwise the bacteria deeper in the cluster of cells would die as no oxygen and food would reach those cells) and thereby the way to multiple cellular organisms was started. Thus, in the beginning, entropy increased until it reached a maximum, after which it decreased until a steady-state was reached whereby opposing forces force cells together while others try to spread them. And indeed, often organisms that live separated from others are less successful (for instance, more difficult to find a mate).

The same with space: after the Big Bang, there was lots of chaos and particles were moving in all directions. However, after some time, particles stuck together, and formed stars and planets while other areas became almost empty: the entropy of the universe decreased until a steady-state was reached. And even now: in the centre of galaxies there are black holes absorbing everything, even light. Still, new stars arise here at some distance from those holes. But in the end, most things may end up in the black hole, while stars too far from the centre may escape in the emptiness of the universe, die and there material will be completely lost. However, the dark hole may become so heavy that everything will be attracted to it, and entropy will decrease further. At a certain moment, it may become so heavy that it may explode again: a new Big Bang, entropy is maximum and will decrease again over time (indeed, some scientists believe that there were a number of big bangs in the past).

Thus, I think that THE law of nature will be a very simple one of two opposing forces. However, the above has one problem: chaos is necessary before order can be established. And I fear that chaos is very high in the world at the moment. However, in the distance I see a shiny future.
