This thread is intended for the scientific view of how you think the world should end, not the same as the poll as to how you want it to end.

How will humanity become extinct? Will we make it to the end of habitability on Earth (After the Sun becomes a Red Giant, and either Earth is sucked into the Sun or burns up, however it would become too hot for us to actually see that happen most likely, although with the rate of technology improving, will we be able to make it to that day with some new form of heat protection or such?)? Will we die out with the enemies being each other?

I personally think if we put aside differing views and unify our ideas between countries and one another, there might be a chance humanity can last pretty long, however, it will take some time before 7 billion people agree on one thing. Providing no external threat, such as a meteor impact or a life-threatening event occurs, we will most likely as humans evolve. I personally hope that the issue of global warming is slowed, as the Earth is only getting harmed by the deterioration of the ozone layer. With improving technology, many diseases and new diseases will have vaccines made for them, and hopefully spread throughout the world. I doubt we will lose to a disease, unless the ozone layer is fully destroyed, and we lose to a form of severe cancer or cell mutation.

Post your opinions and thoughts below.

Truthfully I think since we have gained self awareness and greater intelligence as a species, the only species that we know of to have done both those things, we won't die out. Technology is largely how humanity evolves rather than natural selection ever since the start of recorded history and technology's pace far surpasses anything nature can bring at us. The sun is good for many millions of years, the likelihood of a meteor impact is very low and anything along the lines of a planet killer would be detected in time to deflect it, disease while still an issue are countered by medicine technology, a world war with nuclear weapons while destructive would not kill off human kind, global warming will not kill us off, and etc. Humanity is very, very good at adapting and if human kind is able to spread out into the universe in the next several thousand years, as a species we are pretty much immune to total extinction then.

Ah, that's true. I completely ignored moving to another planet in my original post. And evolution will help us to adapt to that type of environment over time, and by the time we would make that decision, we should have the technology to guarantee safety.

I believe humans can survive beyond the transformation of the Sun into a Red Giant.


Meteor impact is almost out of the question because there are several thousand astronomers looking at the sky each night from all over the world. They could always send something to intervene its entrance.
A super virus is out of the question as well, because at 7 billion people, at least 6 billion people will have natural immunity to the super virus... and that's really overestimating the viral potential. We now have quarantine protocols in place.

And the chances of two galaxies colliding or running into a Black Hole are very very low that it'll probably never happen.

The most complex and difficult era for humans would be the transition from the Sun in its current state into a Red Giant. Global temperature will obviously rise; but since this is a gradual process, human evolution will most likely adapt along with this process. The real problem will come when water begins to evaporate and ecosystem can no longer sustain plants and lifeforms.

This will be billions of years in the future. I'm predicting that by that time, humans will have built life-sustaining stations in outer space.
I don't really know how this will work out because water and energy are two things required in space. And these things are not easy to get.

I'm just predicting that by that time, astronauts will have already built a massive space station that have the water and energy required to sustain 100,000 people.
And then they can sort of transport that back and forth from the space station orbiting Earth to the space station orbiting Mars.


This doesn't really sound efficient and easy though. At least not in this era.

But I believe if the humans end, it will be because of the lack of water and energy resources in outer space. I'm not sure if humans can really go out of the Solar System because of distance and temperature.

The end of humanity will just be the end. I think if the world were to end it would be because humans destroy them selves with nukes or create something so powerful that we do not understand that we willl be sucked into a black hole.

We will soon create an AI that exceeds the cognitive abilities of a human brain, which will continuously lead to ever-improving Intelligent Machines that will either take us to habitable planets or move our minds into a digital universe.

1) Sol will likely expand to or very near 1 AU in diameter. Even before Earth enters Sols atmosphere liquid water would have burned away. Earth's only hope would be if it is pushed farther out such as with V391 Pegasi b. Even then life would likely die off.

2) There already have been mass extinctions related to meteor impacts. Even if we detect it if it is in a similar category to the Chicxulub impactor which was 6.2 mi in diameter and released 4.2×1023 J. There is little or nothing we could do.

3) The 1918 Spanish flu killed 50-100 million apporx 3-5 % of the global population. If we get into super virus territory say an engineered Ebola variant while we would not kill everyone we could get humanity to a point of no return.

4) The odds of running into another galaxy 100%. We are due to collide with Andromeda in 4 billion years. All galaxies have black holes at the center so odds are good that parts of our galaxy or maybe earth if it survives the suns expansion could get eaten. Throw hyper-velocity black holes into the mix and watch out.

My personal thought is that we will be long gone out of our native system by the time we need to worry about any major solar (except flares) event or any major galactic event. I predict we are a space faring civilization in 500-1000 years.

I actually think it WILL be a super-virus. As we keep genetically modifying animals/vegetation for consumption we are introducing artificial factors. Combine this with the outright human ENGINEERING of deadly fast-mutating viruses, I believe the immunity level would be closer to 10% of the population.

I think someday some bureaucratic pawn will accidentally (or maybe not accidentally once the "right" people are safe in a shelter) release something totally nasty that was engineered for the worse possible destruction possible and that will wipe out most of humanity.

On the disease issue, even pandemics such as the black plaque or the 1918 Spanish Flu many of which have killed humans by the millions, when placed on a graph against the growth of the human race during their period in time only show as slight indentations or declines within the growth of our species. I agree with your take on the situation our species is a very tenacious creature with the ability to move and adapt in order to survive.

It will be a long list of factors. War, famine, and pestilence being the primaries. Unless we expand our reach for resources and learn to cooperate in order to make use of them. I won't say that humanity will die any time soon. If anything, we are long overdue for some kind of evolution which will secure our place as top link of the food chain much more strongly.

Have you ever read The Time Machine by H.G. Wells? I believe it would be something like that. Eventually, after much scientific discovery and adaptation, we would find ourselves so technologically advanced, we would not be what we would call human anymore but instead adapt to the extremely carefree type of lifestyle where our bodies would have to change to adapt to the lack of actual use. It may not be what you had in mind, but since I can't see humans ever being wiped out because of our ability to adapt so quickly to most situations, this is the next best thing. To lose what we call humanity.

Wow. I say the word "adapt" a lot in that paragraph, but in the end, I guess it's what it ends up to be..
