The Apocalypse!

[Darkswordofchaos]

3. Aliens invading.
4. Rampaging machines/robots.
5. Zombie virus.

Those are all very likely

Really?

3/4 very likley
5 only kinda likley

A big pandemic D:

I'll probably catch it S:

In order of most likely to least, this is what I've come up with.

1. Ozone Layer disintegrates, and we die of radiation poisoning from Sun.
2. Nuclear War.
3. Aliens invading.
4. Rampaging machines/robots.
5. Zombie virus.

Those are all very likely, then we get to the ones that are just barely remotely imaginable.

6. Volcanoes exploding and drenching the earth in soot, changing climate so drastically we can't adjust and we die.
7. Earth gets whacked by a meteor.
8. The Sun's gravity somehow lets go of Earth and we hurtle off in space and freeze to death.
9. Giant natural disaster.
10. Mass suicide.
11. Extremist groups kill everyone.
12. Mass sacrifice to a God.
13. "Anti-Christ" end world.
14. We run out of water like Mars did.
15. The Sun explodes, engulfing Earth in a giant Supernova, instantly incinerating everything in its path.

Ok lets go through your ideas here, 15 is a nice big number I might skip a few...

1. Ozone Layer disintegrates, and we die of radiation poisoning from Sun. ~ This is quite possible, though we'd need a drastic level of ozone disintergration, after all there is already I think atleast 1 or 2 holes in the ozone layer

2. Nuclear War. ~ Well a lot of countries have nukes and if one country launches we'll all follow suit in a scorched earth scenario, though not every country has nukes, humanity is more likely to be decimated than exterminated

3. Aliens invading. ~ Really, seriously, c'mon give me a break. If aliens came to earth (it's not a question of existence thats pretty much a given considering how vast the galaxy is and how little we can explore) then they would most likely have no use for anything we have they would have to be super advanced to get here and if they're that advanced fossil fuels aren't going to get them anywhere. The ONLY way to provide enough energy for the kind of propulsion travel through space needs is a nuclear reactor the only way we know of that is. you can build a reactor now and it'll run in 1000 years time as long as you maintain it.

4. Rampaging machines/robots. ~ Robotics are seriously behind in the capabilities they describe in sci-fi. Should we have the technology to make an independant robot capable of learning and rebelling against programming safe codes then this would be more likely, we don't have that no need to worry. Almost all machine deaths can be traced to human error.

5. Zombie virus. ~ Zombies, c'mon seriously again! zombies are like a physical impracticality. For one the human body when dead cannot digest food or liquid the bowels shut down therefore the idea of the cannibal dead eating us is stupid. The second thing is bones become brittle and easily broken without ever healing. A cut or burn or bruise even can cause major damage without ever healing. The idea of Zombies is good for computer games and movies thats it.

6. Volcanoes exploding and drenching the earth in soot, changing climate so drastically we can't adjust and we die. ~ Technically possible, if the entire ring of fire erupted at once we'd probably be pretty screwed the climate change would be caused by more localized disturbances spreading not by one huge event.

7. Earth gets whacked by a meteor. ~ This is a high probability, should a big enough meteor survive the atmosphere. By the way, corrosive green house chemicals help stop this from happening by increasing air friction and corrosion. Most meteors that strike are smaller than a basketball. but if one the size of a volkswagen beetle hit we'd be in the creek so to speak.

9. Giant natural disaster. ~ whats the disaster? hurricanes and firestorms topped off with an ice age? could be possible but depends on a lot of circumstances.

11. Extremist groups kill everyone. ~ Extremists what to kill all of us apart from their own believers therefore this is impossible unless every extremeist suicided killing 1000+ of the rest of us each.

14. We run out of water like Mars did. ~ Water probably won't run out like on mars because it didn't run out. Water on mars froze in to the poles. I'd be more worried about the oceans becomming acidic and killing us and ruining the water cycle and that poisoning everyone.

15. The Sun explodes, engulfing Earth in a giant Supernova, instantly incinerating everything in its path. ~ This will happen. Without doubt just it will happen in about 8 billion years time. Except by then Earth won't exist, before the sun super nova's it will become a red giant. Earth is close enough that should it not actually be engulfed in the sun's corona at this point it will be completely burnt out like mercury is.

Sorry to pick them apart but really thats just silly saying alien invasion and zombie viruses are more imaginable or realistic than natural events that are pretty much either guaranteed or fully capable of happening tomorrow.

Ok, to your response to 3-5.

3-Look At the history of man. We area warlike race and we enjoy the glory and honor and exhilarating experience of war and battle. Now, maybe the aliens do come in peace, maybe they don't attack us, but the greed of men in wanting this technology will eventually cause one to steal it, and this may make the aliens very angry, and they might start war with the Earth.

4-I don't necessarily mean the robots coming tomorrow, more like in a few decades to maybe 200 years when they will be far more advanced and maybe capable of thinking on their own, and maybe noticing that the student really has surpassed the teacher.

5-Due to the many scientific advances in the medical fields, we are constantly creating new medicines for many things. In the past, we have created diseases, viruses, or bacteria that are harmful to us rather than helpful to us, and it may happen that we create something to cause the cells of a dead being to start working again, and this would cause all of the bodily functions of the said being to be brought back. Though, the next part of this theory is based on religion, and whether you believe that there is a "Soul" or something like that and a "Heaven" or "Hell," and also whether or not the dead feel jealous of the living and wish revenge on them, in which I'm not saying the zombies would consume flesh, but maybe they just lash out in rage and kill for it. Then, you could think, this is not an apocalypse, just a dawning of a new age or whatever, but the true race of man would be destroyed, in which case it is considered an apocalypse in some cultures.

And for 14, I should have said usable water, sorry for that.

There is the possibility that the virus could attack and enter cells destroy and replace the midochondria and power the cells them selves making the resportory and circulatory systems redundant.
This could also revive the digestive systems or mabay th virus could could transfer food straight from the stomach.

And then we clone people without any genetical defect whatsoever, call them Alice, release the virus upon the world and build giant underground complexes where we do dangerous research. Also, we have AI.

Or we could just take the train straight to idiotville.

Take a molecular cell biology course before you sprout such nonsense again.

A quick sumup of this page:

Reviving dead body cells = Walking, rotting dead craving for human brains

[Darkswordofchaos]

Well to be serious if we dont kill ourselves with nukes and stuff statisticly the most likely natrual thing to destroy the world would be a gigantour meteor.

You just described the movie Knowing.

Really? How old is it? Is it from the sixties or seventies?
