Peacefully, the three-dimensional universe coalesced into a series of two-dimensional plates. Within those plates, little balls began to form from the debris. Over a little time, oceans and atmospheres formed and life flourished on several particular globes.
Intelligent life came somewhere towards the end of life’s overall run and inevitably ruined it for everyone aside from the resilient few. Ravens – a rather nifty bird, of all things – did pretty well for themselves on Earth, taking advantage of pretty much everything humans threw at them.
Several species of bacterium and smaller creatures had no trouble with adapting to various chemical poisons and radiation, and intelligent life inevitably rose again and again, each time being annihilated by themselves as if it was some sort of tradition.
In the end, however, life just kind of gave up throughout the Universe and left it to the elements to roam free, no longer manipulated by curious minds.
By this point though, the Universe is pretty cold. Mr. Entropy has been messing the place up and causing atomic chaos and now there is so little order that energy has just sort of spread out like a regular tub of butter over 46.6 billion slices of toast.
Since temperature comes from the interaction of atoms, there is no longer any temperature because everyone has isolated themselves in their own little patch of the Universe. There were once good days where atoms would jiggle around together emitting heat, since kinetic energy – movement – is the one true form of energy – but I guess after a while you kind of get bored of each other and drift apart. Eventually you’ll stop expecting Christmas cards altogether. I’m pretty sure that’s what Entropy means.
They are consequently collectively destined to decay into nothingness all by themselves. Galaxies were, are and will continue to be things of the past, and at the end of time – a little before 3 o’clock if I calculated it right – temperatures will reach absolute zero (-273.15°C) and penguins will have to find themselves a new, slightly warmer universe in which to reside.
Atoms are a lot like penguins; without coming together and sharing body heat, the penguins tend to get cold and inevitably die alone. A lonely atom cannot share its kinetic energy with its ‘friends’ once it is isolated, and probably wouldn’t even if it could. I’m pretty sure that’s what the Law of Conservation of Energy means.
Of course, there is a solution to all this. If the atoms could just solve their issues with each other, we might see them starting to group up again and get a few barbeques started. This obviously generates heat and we’ll immediately be getting back on track.
With enough friendly atoms, the combined mass would create gravity. Not much is needed, and since it’s a natural result of their turning up to the party, nobody will really mind. Eventually, the party will be so popular and attractive – so to speak – to others that they will have fellow atoms queuing round the corner. Some particles, like electrons, may even turn up to multiple parties simultaneously.
Perhaps rival parties will form elsewhere and other gravitational sources will attract other extroverts, and perhaps some smaller, introvert-friendly invitations might prop up here and there. Something for everyone.
Without even realizing it, there will be numerous groups forming into various elements again like the good old days as a result of interacting with each other and trading various particles here and there. Helium being the most extraverted of elements was always the most popular, and pretty self-absorbed. So they ended up at pretty much every party along with Hydrogen and to a lesser extent, Lithium and Beryllium. These guys are pretty lightweight and light hearted though, so it took some of the bigger parties to create enough pressure to get the more stubborn, introverted elements like Magnesium and Carbon to come out. They did this by means of a strange ritual of colliding into each other at speeds incomprehensible to intelligent life forms since past. Mg and C tended to hang out with the other 80 or so losers in the bedrooms of these parties, aka, the core of stars and other similarly troublesome places. But given enough time, enough interactions will give them the energy needed to see what all the noise was about outside.
Eventually parties come to an end, often due to the particle police coming about the noise. Given that a typical star party might reach constant volumes of about 290db, this is understandable. So with the police ruining it all, the star will explode. It was getting on a bit anyway. The atoms will have to dash before they get caught and so they will once again get sprawled all over the place.
But wait; now all the introverts are out and about. What will become of them? Well, essentially the same as everyone else. The gravity will be spread out, but not nearly as much as the aforementioned butter scenario, and so it will drag everyone back to what I suppose will be the after party.
Clouds and clouds of atoms will whirl themselves together in renewed two-dimensional plates in a three-dimensional universe – solar systems – and once again clump together in significantly smaller parties, as if to keep from troubling the neighbors – how considerate.
Before we know it, more Earth-like planets will form. Jupiter-like planets were and will be always more common, since Helium and Hydrogen really are the true party goers. But hey, Iron and Carbon don’t mind the occasional chill out session and that is what places like earth will consist of.
In time, carbon will clump together and form life of its own. Carbon has always been the most creative atom in the universe so quite a lot of diversity will come from it, just like last time. But hey, who knows, maybe it will avoid the whole ‘intelligence’ thing and stick with what works; bacteria and, at most, the occasional raven.
