I had a recent stoned conversation with a friend about how the human race would come to an end.

So how do you think we will all die out?

Natural disaster, religous act, A.I and robots taking over, will we eventually run out of resources, or will we kill each other off in a nuclear war?

Also, what do you think will be left of the world?
Will a new dominant species arise and evolve, or will our planet become a desert?

Why are so many people concerend with a potential end to humnaity? Is is that we're raised in a christian world that assume our sins will be punished?

HappyMan, he's posting the question on a message board, not running around in the street shrieking that the sky is falling

Personally, I'm guessing that we'll either screw the Earth up so much it can't support life anymore, or there'll be a nuclear war. But I don't think it'll happen anytime soon.

My thoughts on the subject.

Look at history. Throughout the ages, the human race has been gaining more and more control over the world, and we've been learning how to manipulate our surroundings. We get more and more efficient at it. In the future, I think we'll be so efficient and skilled at manipulating the world that the world will turn into a kind of machine planet. We'll undoubtedly have different energy sources by then.

As for the fate of the human race... I think the human race is an infant god. We'll gain so much control over our surroundings in the future. Look at where we started-- fire, to electricity, to nuclear energy, then the gene code. Imagine if we learned how to play with time in the future.

Good or bad? Neither. I think it's absolutely essential that we preserve the natural world as much as possible, but I also think this change is inevitable. What intrigues me is what we decide to do with our god-like powers.

The key to survival will be spreading ourselves out. Once we find other habitable planets and colonize them, or once we gain the ability to terraform uninhabitable planets that exist inside the habitable orbit zone of a star, that will go a long way towards ensuring our survival. Doesn't matter if we accidentally blow up Earth if we have billions of people on Mars, Neptune, and Alpha Proximi. The vacuum and vast distance between planets will be a great insurance against large-scale disasters once we are on more than one of them.

If we can manage to do that, we'd pretty much be protected from ourselves, so then the only danger would be outside influences. Aliens is a possibility. Divine intervention is a possibility. And larger-than-planet scale cosmological disasters are still a possibility. Like if our sun goes supernova for some reason in the next millenium, I doubt even the colonization of nearby solar systems would save us considering the scale of an explosion that size.

If our technological leaps allow us to expand even further, either by long-distance expansion (i.e., colonization of other parts of our galaxy) or other as-yet-unfathomable processes (like someone mentioned above, time travel which might lead to alternate dimensions, etc to colonize), then we will be protected from even things like supernovae.

But there will never be a guarantee of permanent security.

Will it ever end ? Thinks that might happen in the future :

1.Earth Over populated
2.World Leaders Search The Universe For A Second livebale Home That by that time we have disocered at least 1 or 2 human friendly planets .
3. Start Over their new planet

Their is so much that could happen between now and who knows ... Every Human being troughout history has been thinking about the end of everything , You just think about it , Everytbody keeps saying the future , in the future this will be better etc. So its like a cricle everybody keeps thinking the same things .I dunno

I think it's going to happen a lot sooner than we think. My guess is that if Bush doesn't start a nuclear war and kill us all, we will run out of fresh water to drink. This won't kill us all (us Canucks will be ok) but it will possibly cut the human population in half.

I don't think our technology will ever be able to reverse or offset the damage we have done. Our only hope is to ban reproduction for a decade or so, or start living like the animals.

My science teacher told me that all stars grow and grow and grow until they turn into a black hole. So realizing that the sun is a star, I shiite my pants. I then realized that the occurance would probably be thousands of years off. That will suck though. For future people.

Higher Logic

Here's my theory:

I don't believe we are any more advanced than we were in say Roman times. We still do the same things, we have traffic, we have places to eat, we have sickness and illness, we have all kinds of things everywhere which are no different from back then. I believe natural disasters take over humanity and the whole cycle starts over. Who is to say that we haven't been cycling over and over, and maybe 8000 years ago something happened and the race started over, we just keep starting over again and again and eventually reach a point where we can't go further until a disaster wipes us all out (ice age for example).

Put it this way, eventually an ice age will happen again and people/animals will be wiped out. New species will rise up and the human entity will be here again, we'll be back in the "stone age" like we were so long ago, and it will take another 8000 years to catch up to where we are now, but before ya know it BAM something happens. You wouldn't have a recollection of passed events, so you'd make stuff up (like we do now). The human mind has a nack for creating things that don't seem logical, why not eh....

Not all stars turn into black holes. If your science teacher told you that, he needs to be fired. Certain conditions must be met -- the most significant of which is the star must have sufficient mass. Generally, once they run out of fuel to burn stars will collapse in on themselves due to gravity (although this isn't always the case). However, only stars of sufficient mass will collapse themselves into a black hole. Red giants are the most common. If it doesn't have enough mass to form a black hole, however, (and most stars don't), it will simply collapse into a White Dwarf (I think, been a while since I read up on all this stuff).

Nevertheless, not all stars become black holes (very very very very few in fact), and any science teacher that teaches that probably also hands his toddlers a pencil and says "Ball." just to mess with them.
