Most likely in a million years when the sun explodes. I dont see technology advancing enough to stop that huge thing in space. Hopefully by then we'd have migrated to different galaxies by then.

Either when the sun explodes or nuclear warfare. Probably nuclear warfare if the world keeps going along at this pace.

Of course, humans will eventually become extinct. It won't even take millions of years; the natural cycles of the earth will do the job just fine and I'm not even including social problems, overpopulation, viruses, etc.

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.


Technological Singularity suggests that humans will be replaced by an offspring that's divergent enough to qualify as a seperate species. Man will meld with machine, and possibly a bit of genetic engineering as well; those who can make the transition will achieve a pseudo-immortality, those who can't or won't... will be uncompetitive, and fade out over time.

This will happen well before the sun expands.

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.


With early enough detection, we could theoretically divert even something like that into a "near-miss" event rather than an impact-event. Of course, we'd also need a way to get out to it with enough power to alter it's trajectory - earlier detection means we need to make less of an impact on it's trajectory, but also means we have to get out further.

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.


It's been modeled, and the impact is deemed unlikely to have any effect on our solar system. Not impossible, but unlikely.

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.


Warp drive, allowing us to bypass the speed of light, is *theoretically* possible: http://www.space.com/17628-warp-drive-possible-interstellar-spaceflight.html

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

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.


Not only it, the Sun rises his gravity too. Is believed that Sun will "absorb"(push until, he burns itself) Mercury.
And Earth become, no more suitable for life. A lot of massive solar flares too.

We can hardly survive in this planet with all these illnesses and wars so I hardly think we can survive in space, if the end of the world happens by atomic bombs, overpopulation, another big bang or the apocalypses...we are all going to die! or the age rate will decrease...most people don't reach their 100s...in the past, people could still live 100+ years...we're getting weak by the second and mother nature is getting mad at us by the minute.

To all who have no hope in the future, and who discount God's Word, The Bible, life looks bleak in the future, However the Bible does have a message of hope for those who believe in God and do put faith in Christ Jesus.

The Bible does not say every good person goes to heaven, But it does say where they will be.

The sign of the end includes global war, “great earthquakes,” “pestilences,” and major “food shortages.” (Luke 21:10, 11; Matthew 24:7, 8; Mark 13:8) Also marking the “last days” would be a serious moral and spiritual breakdown in society. (2 Timothy 3:1-5) Have “all these things” occurred? (Matthew 24:8) Yes—to the point that many people fear the future. The newspaper The Globe and Mail stated: “Some of the most respected thinkers about science and society are issuing alarming prognostications about humanity coming to an end.”

In one very important respect, however, those prognostications are wrong—humanity itself will not end. In fact, the intervention by God’s Kingdom guarantees it! When giving the sign of the end, Jesus Christ stated: “This good news of the kingdom will be preached in all the inhabited earth for a witness to all the nations; and then the end will come.” (Matthew 24:14) How has this prophecy unfolded?

In over 230 lands, Jehovah’s Witnesses are proclaiming the Kingdom of God. Indeed, the title of their primary journal is The Watchtower Announcing Jehovah’s Kingdom—Jehovah being God’s personal name. (Psalm 83:18) The Witnesses’ program of Bible education is helping countless individuals and families to replace harmful lifestyles with clean and peaceful conduct that conforms to God’s standards. (1 Corinthians 6:9-11) As a result, millions of people worldwide are confident that they will gain God’s protection when his Kingdom intervenes in mankind’s affairs.

Indeed, they will see with their own eyes the fulfillment of Christ’s model prayer, sometimes called the Lord’s Prayer, which states, in part: “Thy kingdom come. Thy will be done in earth, as it is in heaven.” (Matthew 6:10, King James Version) Have you wondered what life on earth will be like when all humans love and obey God? The following Bible passages may help you to understand why the expression “good news” is fitting.

When God’s Will Is Done on Earth . . .

● There will be genuine peace, not just the absence of war. “Jehovah . . . is making wars to cease to the extremity of the earth. The bow he breaks apart and does cut the spear in pieces; the wagons he burns in the fire.” (Psalm 46:8, 9) “The meek ones themselves will possess the earth, and they will indeed find their exquisite delight in the abundance of peace.”—Psalm 37:11

● All will have an abundance of food. “There will come to be plenty of grain on the earth; on the top of the mountains there will be an overflow.”—Psalm 72:16.

● Perfect health will prevail. “No resident will say: ‘I am sick.’”—Isaiah 33:24.

● Everyone will have a comfortable home. “They will certainly build houses and have occupancy; and they will certainly plant vineyards and eat their fruitage. They will not build and someone else have occupancy; they will not plant and someone else do the eating.”—Isaiah 65:21, 22.

● All forms of suffering will end. “The tent of God is with mankind, . . . and he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.”—Revelation 21:3, 4.

I see it happening a few ways.
First, power hungry fools. Countries and their dictators set on ruling the world. Wishing to gain as much power and control over everything possible igniting huge wars. Countries having to choose sides to either protect themselves or fight back. But worst of all is our development of weaponry world wide. Unlike the wars in the past countries can now annihilate each other with the press of a button. Nuclear wars.. killing not only humanity but the earth itself.

Second, global warming which will take a lot of time. Glaciers will all melt completely covering most lands with water. Humidity will become unbearable and I believe it will cause the earth to reset itself. The whole Ice age and volcanoes erupting everything kind of reset.

Third, incurable epidemic that will ultimately kill everyone.

Last, aliens. Lol I don't care what people say, I know we are not the only life forms in the universe. There are superior beings out there who may one day expand and kill us all.

it will be a government fearmonger that goes too far
weve already got the global warming alarmists pushing to build giant mirrors to place out in orbit between us and the sun, fancy reflective chemicals dumped into the atmosphere (like nuclear winter), and all kinds of other exotic "fixes" for natural cycles because man thinks hes at the center of everything.

nuclear war wont kill off everyone but it might thin the heard quite a bit and cause all kinds of post apocalyptic crazyness.
im really pulling for zombies...

Well, assuming we don't nuke ourselves to death first, we'll probably be done in by a major catastrophe on Earth, such as a super volcano going off, like the one in Yellowstone. Or a couple of large asteroids we failed to detect impact Earth in a few places in succession.

Barring that, if we can manage to not kill ourselves long enough to set up self-sustaining colonies in space, humanity may very well be extinction-proof, barring something crazy happening first, such as a Gamma Ray Burst that fries our solar system (I don't think being on the other side of Earth would help protect against something like that due to the immense energy those things have), or a hostile alien invasion where they bring in millions of warships. Yeah, we're pretty screwed if that happens, unless a friendly alien fleet that can take them on shows up...

But the likely scenario is that we start becoming Borg-like in order to enhance our survival in space and in general. Why worry about a heart when you can install a piece of equipment that functions much better and can be easily replaced should it go bad? And eventually we may just shed biological bodies since they're prone to errors such as cancer and diseases. But by that point, can we really still call ourselves human? Philosophers in that day and age will debate that.

I expect that homo sapiens would either become extinct from a meteorite blast or voluntarily through gene alteration or technological integration.
