I mean, what are the current predictions pinpointing the exact day of the Armageddon? Nostradamus’, other religions, etc…
Well it’s going to end today here, which will be tommorow there. So by the time you read this the world will already have ended.

What do you mean by the word “world”?
Do you mean your world (your perception and mental ability until you die), the planet earth beyond your existence? beyond humans’ limited sensors (eyes, ears, taste, smell and touch)? The dictionary defines “world” only in relation to human beings.
Obviously, the biological organisms on earth depend on the star “Sun” for their existence and survival. The fact is that one day (in a distant future) the sun will disintegrate, as all stars do. Millions of years before sun disintegrates, earthling life (if any by then) will cease to exist due to gradual changes in solar activity prior to total disintegration.
Between now and then, there is always the possibility of a comet hitting the planet, or a man-made neuclear / biological catastrophe. The former is currently beyond our control. As for the latter, the key question is how we human beings, starting today, can unite and collectively embark on a universal program to design our own evulation and expansion of our brain power from here onward. The U.S. spends $300 billion per year in defense (over a third of which is spent in development and procurement of sophisticated war machines). But we spend zero in accelerating the evolution of human brain from the current snail pace to a global network of brains, finding and implementing solutions so that “the world is not going to end”.
I think the sun has about four billion years until it gives up the ghost and goes nova, engulfing the inner planets (from Mercury to Mars) in hot plasma. Of course, that area includes Earth, which will be turned into plasma very quickly by the experience (unless our distant descendents have moved it by then). So four billion years from now seems as good a date as any for the ‘End of the World’.
Aside-Killing off all humans would in no way affect this planet as a whole. Most life would go on just fine, in fact, without humans around. Even if we did manage to turn large areas of this planet into molten, radioactive rock life itself would go on, somewhere, and the planet itself would continue in its orbit and rotation. So proposing scenarios that would merely kill off all humans are not, technically, end of the world scenarios.
[obNit] The sun is not going to go nova. Nor supernova. [/obNit] It’s going to swell up into a red giant and then eventually shed the outer layers of its atmosphere in a relatively nonviolent event that will create a planetary nebula (so called because they looked similar to a planet in early telescopes, not because they’re caused by planets). The core of the sun will remain as a white dwarf.
The sun is losing matter, so the Earth’s orbit will gradually move outward and it may be large enough (there’s uncertainty about how large the orbit will get) that the sun as red giant will not encompass it. But it will be a close thing either way.
But well before that happens, the sun will heat up enough to roast life on earth. I’ve seen estimates from .5 billion to one billion years for this to happen.
This thread reminds me of an SF story who’s name and author I forget. Someone has invented a time machine and is selling trips to the end of the world. Some people are holding a party and each couple has taken the trip. But the thing is, no two couples see the same thing. One couple saw the end of the sun, another sees the last living thing expire, and so forth. As they discuss each couple’s experience, they also hear a report about a current environmental disaster related to that end of the world. So the reader is left to wonder exactly how far ahead in time this machine will have to travel.
When the Red Sox win the World Series…
I thought the Cubs winning was the sign that the end is here…

No, no, no. It’s when the Lions win the Super Bowl.
“And lo, when the Lions from the city of motors, rise up against their foes and conquer them, those that have persecuted them and their followers will know the end is nigh.” The Gospel according to Tagliabue 2:35-36
with my luck, it’s end about 2 weeks after I finally get my shit together.
I mean, it’ll end…
of course
Phew… at least we know you don’t have your shit together yet. The world won’t end in the next two weeks.
Don’t worry–we’ve got YEARS! 
I haven’t decided yet. 
When I do, you’ll be the first to know.
Well, whenever it is, don’t get caught in a foreign tower.
That’s all I got.

JDT called all those that had nothing meaningful to say or add to an OP – riff-raffs.
Too many riff-raff comments, and one soon gives up on scrolling a thread to discover something interesting that someone may add towards the end of a thread.
Recommendation to the moderators: Anyway to clean and filter the riff-raff comments from a thread, so that one can follow the relevant comments to an OP without having to scroll through a lot of irrelevant BS?
I’ll also agree with the astronomical sources of The End, but I’ll note that you phrase it well in regards to The End predicted by religions, cults, etc…their predictions keep changing every time their fated day passes without incident. They have to keep updating their “current” predictions. It seems like the end of every century (and this millenium) has its end-of-the-worlders. And things like Nostrodamus’ quatrains are interpreted many different ways.
But I don’t have a list of the current dates being tossed around by cults to specifically answer your question. I’m sure they’re listed all over the web though.
One Cell, you do realize that your above post is riff-raff? Anyway, whatever the hell you want to call it, it’s usually the best part of what the SDMB offers.
As it is, only yourself, dltique, and derleth had anything real to say, but that’s cuz you guys pretty much covered all the bases. As asked, the OP really can’t get an answer. As Phobos hinted, there’s way too many dates bandied about, because there are so many ways to interpret the sources.
Also, the OP seems to be referring to supernatural ends, which makes it kind of hard to pinpoint an exact date.
Your guys’ answer is the only real answer, but I don’t think Uniball quite had heat death of the universe in mind.

If the OP means “When will the Apocalypse take place?”, the answer is 2030 A.D.
Sheesh, we don’t want to remove all the fun from this forum! I don’t like off-topic threads because they crowd out other threads on the front page. But funny posts? Heck, that’s encouraged!
