I found this article and well it sums up about every single major threats to the human race~! http://www.netscape.com/viewstory/2007/01/...d%2F&frame=true

Enjoy!... um or just read :smokin:

true ,reality might not be real but what about non reality is that unreal, and who is the one who waketh up to discover this , each of us in our own sphere ?does ones waking up to find only a dream deprive others of a well fortuned realism , i must say number 20 appears much to spacial for this rock hard existance we seem to be facing , 1-19 sound like winners though.

...interesting idea.

Can I add something to the list? Geniside, mainly in the form of population control and cuting down our "over populated world".

Oh....I know one....A planet or Planetoid collision.

16 Robots take over - That's already happening!! Haven't you seen Transformers? The guys Xbox360 turned into a robot and choked the guy. Bill Gates is gonna be the controller of our worlds. We must take him out while we still stand!

SOme of these certainly could happen tommarow in fact, but #20 I thijk was added jsut to make it 20 ways earth could be destroyed. Global Warming in my opnon could never destroyEarth only affect us in some way. Black Holes roaming the Galaxy? Now that is a very scray thought but hey it could happen since you can't see black holes. here is another thing that could destroy eatth as we know itspontaneous collapse of Earth things can only expand or contract so much befor they collpase or implode. since we don't know which is happeneing then this can't be ruled out either.

There are other ways of detecting black holes:
The Tricky Task of Detecting Black Holes

Seeing objects that don't reflect light is tricky business. And black holes are as elusive as a target can be. The gravitational whirlwind of these cosmic wells draws inward with so much force that even light can't escape their grasps.

This poses a tricky problem for scientists, whose instruments typically rely on light-whether it is visible light, radio waves, X-rays or infrared-to observe objects in space.

Astronomers currently spot black holes by detecting the high-energy radiation emitted by swirling matter falling into them. Before matter passes a black hole's point of no return, called the event horizon, any radiation it emits can still escape. In a decade, however, scientists hope to spot black holes by looking at the warps in space-time created by their immense gravity.

So you never actually see the black hole just the effect one causes? Sure sounds tricky to me.

i'm more optimistic than that, i think humans will survive whatever the circumstance, humans have had hundreds of wars, 2 world wars, 2 nuclear weapon attacks, dozen more nuclear tests, plauges, epidemics, metorites, earthquakes, humans may be stupid and ginorant, but we do one thing well, and that is survive, i'm optimistic, that despite all these disasters, we will carry on our existence,
although to be honest, now is the time for humanity to sort itself out, although i think we will survive, there is more to life than surviving

Yes, but as a species, millions will die but not the whole human race.

global warming is most likely

Not in my opnion. A asteriod hitting us is more likely to me.

I think the rouge black hole ones most likely to destroy earth + humanity.
But the solar systems been here a few billions years, Humanity would have to be really unlucky for it to happen in our species earth time.

I don't believe any slow gradual change such as global warming could wipe us out.

but global warming isn't a slow gradual change, its happened in what, the past 100 years, probably more like 60, and we're noticeing changes, but usually for changes to happen like that it takes millions of years, global warming is a rapid change in my opinion, but not one which could wipe us out,
i think war is likely to decimate the population, and then maybe, just maybe, humanity will learn, that violence doesn't actually help

But then global warming doe slo wdown and spped u pand a volcanic erutpion like Mount Pinautaubo in The Philliipines in 1991 temperrely reversed global warming during the "hottest" years on recored, the 90's.

i'm sorry, but i don't understand your point, probably me just being dumb and quite tired, but could you please try and re phrase it, cheers

SInce it does not warm up very year at th same rate 1 degree and in some years hardly at all it's not such a big problem. Only 100 years of climate data is not much given Earth is 4.6 billion years old. And alot of places only have weather records going back 25 years.

thats true, but on the day after september 11th, all the air traffic in amrica stopped, the temperature changed by 1 degree, may not seem much, but if thats the difference stopping planes for one day makes, imagine if what damage we are doing to the earth, we can't deny we're fucking it up, and trying to justify it is playing into the oil companies hands, people have to realise, we WANT cars, not NEED them, and i've also heard a rumour that plans for a car based on the fusion of hydrogen and oxygen has been hidden from view by the major oil companies

I don't mean slow and gradual from a geological point of view, but rather a personal one.
It takes the earth hundreds of years to change 1 degree.
It would take us 10 years to build a defense against it (Provided they tried to do it, properly), and even less if not doing so could result in the end of humanity.

The arctic ice records, that can be used to calculate temperatures as far back as 10,000 years (I think), Show that climate changing has happened throughout all history, from times the earth was a floating ice ball, to it being a scorched, boiling planet, barren of almost all life.
But we have an effect, true.... but..... its been worse, its going to get worse both naturally and by us.
We have something alot of other species didn't have on their side when they faced this; technology, the ability to think outside of instincts, and opposable thumbs to carry out our plans.
