Robert Frost speculated about the world ending in fire or in ice. Which do you think is likely to end us all: meteorite, global warming, nuclear weapons, zombies, or the superflu?
Here's my theory on how the world will end:
Technology will go past bombs and shit and turn into pure biological warfare. One day, there will be a poisonous/viral/bacterial serum that will be injected into a war hero by his or her respective country to eliminate their enemies by sacrificing said war hero to infect everyone, and it will spread in much the same way as AIDS*, but due to differences in biological makeup, some will only become a little sick, and the governments will label it as a flu of some sort and name it after an animal, such as a swine, this flu will spread and infect others to the point where it becomes a "spuerflu". Others will be more sick, and some will be completely immune. however infected someone is, this virus or whatever will mutate into something different and will slowly get worse and worse until the victim's body and mind (or even slow enough that the victim's children) is completely FUBAR, and they have the stereotypical appearance and mannerisms of what the media has defined as a "zombie". These zombies will attack anyone they get near, and anyone who was not immune from the get-go will begin the same process of the original infection, but since the zombie's genes are already mutated then transferred into their victim, they will go through the process much faster and almost instantaneously become a zombie. The government will quarantine infected areas and gather the immune in a safe place and start trying to get rid of the zombies. Due to the fact that the biological makeup required to be completely immune is so specific, the ratio of immune to zombie is heavily skewed towards the latter, and thus, the immune are heavily outnumbered. The government will decide to bomb the zombies, since no matter what anyone's genes are, being blown to hundreds of different places is a permanent end. The zombies will be heavily nuked and since the zombies are the extreme majority of the world by now, as stated before (ratio of infected to zombie), that will be a hell of a lot of nuclear destruction. This massive overuse of nuclear WMDs will not only severely damage our Ozone layer but it will create extremely forceful explosions all over the world, and the force of the impacts will throw the world off of its rotation. We will be "pushed" closer to the sun, eventually, we will fall back into a steady rotation with our proximity to the sun similar to that of Venus. This will result in an intense rise in heat and our Ozone layer will fially be destroyed, therefore, the surface of the earth will be hotter than the core and going outside will kill us immediately and all forms of civilation will burn and disintegrate in a short time. To escape this hell on earth, the remaining population will migrate deep underground and re-establish a new community and try to live peacefully ever after with what we have to work with. Since we are now in a rotation that is closely in line with Venus, it is only a matter of time before we become dangerously close to the planet. Once we are close enough, the gravitational pull of both planets will attract each other and they will collide like magnets. Venus, being smaller than earth, will crash in a similar manner as a meteorite, but since Venus is much larger than the standard meteorite, the shockwave from the impact will compress the earth, and crush all civilization beneath it, thus, leaving no one. After a couple billion years, life forms from Venus (unknown by humanity, since we could never explore Venus enough to discover said life forms) will evlove into fire-based organisms and establish a new civilization and my skeleton will later be displayed in the new museum of scientifc history. Since this new organism will define their own system of communication, and we will be labeled: Dinosaurs.
either that, or Metal Gear Solid.
* My theory on the spread of AIDS is that the above theory is already happening. Someone doesn't like us and sent in their patriot, who has done his job, as it is obvious that a hellalotta people have AIDS. within a couple lifetimes, there will be "zombies" so along with our rough economy, as well as the pessimistic look of the future, having kids would be an act of sadism.
EDIT: Also, I believe that the end of the world is not predicted by the end of the Mayan calendar, I think some ancient Mayan dude got tired of writing all that shit out, and I don't blame him, if I wrote each day for a few hundred thousand years, I'd get insane cramps in my hands and would totally stop too, like "Okay I mapped out the next few hundred thousand years, can I have my damn cookie now?" and so there, Mayans didn't predict the end of the world, they just got bored with doing that shit.
