SUMMARY

The discussion centers on various theories regarding the potential end of humanity and Earth, with participants suggesting scenarios such as nuclear holocaust, environmental disasters, and cosmic events. Key points include the inevitability of extinction due to catastrophic events, the role of human actions in accelerating these outcomes, and the potential for space exploration as a means of survival. Participants also express a mix of pessimism and humor about the future, highlighting the complex interplay between human intelligence and destructive capabilities.

PREREQUISITES
  • Understanding of environmental science and its impact on human survival
  • Knowledge of nuclear physics and the implications of nuclear warfare
  • Familiarity with theories of extinction and population dynamics
  • Awareness of space exploration technologies and their potential for colonization
NEXT STEPS
  • Research the effects of climate change on global ecosystems and human populations
  • Study the historical impacts of nuclear weapons and the concept of mutually assured destruction
  • Explore advancements in genetic engineering and their ethical implications for future generations
  • Investigate current space exploration missions aimed at potential colonization of other planets
USEFUL FOR

This discussion is beneficial for environmental scientists, futurists, policymakers, and anyone interested in the long-term survival of humanity and the Earth. It provides insights into the potential risks and challenges that could lead to extinction, as well as the role of technology in shaping our future.

simple question, but i know i probably left out a few scientific reasons, so post them!
 
Physics news on Phys.org
free for all death match!
 
Do you mean how will the Human Race end or the actual earth?
 
I think he means human race because a nuclear holocaust's results would be nothing compared to some of the stages hte Earth has been through in its life-time.
 
human race
 
There will be and environmental disaster
The air and water becomes so toxic that it is uninhabitable

These two seem closely related.
 
Just reading through the options I'm dying for a free for all deathmatch, but Penguino beat me to it with his enthusiasm. Like a real life game of Quake or UT, last man standing. I'm so there. Lock and load, Penguino. One day.. Now I must fantasise about the inevitable apocolapyse. Rock on!
 
The Earth gets sucked into the sun?
 
world will expand as much as possible and then a big explosion will happen again!who knows maybe sth like big bang would happen again and again ...
and a new world will come into existence!

The Sith Empire will invade us and turn all humans into slaves and use us as fodder against the galactic republic

I don't think we'll make it. How so pessimistic that is and I'm usually so optimistic. You read stories about what man will do in the distant future, you know, like when the sun becomes a red-giant. Are they kidding? There won't be any humans around when that happens. We're all a part of one grand genetic lineage that ebbs and flows like a wondering river. We'll take our place for a moment and the next act will follow.

Some catastrophe will wipe us out, an extinction like so many before us. We solve differential equations in here about population growth and note that when the population drops to a certain level, it does not rebound but rather tends to extinction. So if such a catastrophe does occur and fails to wipe us all out, it may drop the number below a threshold that we cannot recover from.

Suppose though space exploration and colonization is an avenue for escape.

There is another possibility. (Maybe?)
Depending where we are in the area of genetic research when/if such an event occurs, we may be able to rebound from it and end up with a stronger, more advanced population. Of course, it would depend on the catastrophe. A large enough meteor, nuclear winter, climate change, or plague would present different problems. A plague would probably be the easiest to overcome; since it wouldn't change the environment.

By environmental disaster, do you mean any disaster (human caused included), or those beyond our control? Would human induced global warming with catastrophic effects such as flooding due to the melting of polar ice caps be under environmental disaster or the last option with the air and water being toxic (presumably due to our own waste output)?
 
  • #14
Global warming will melt the polar ice caps enough to throw us into a quick ice age. Countries will wage war against each other for survival which will ensure the world wide use of nuclear weapons ending total human life on earth. Many years later the world will come out of the ice age, the Earth will heal itself and nature will continue on. Millions of years later something or someone will be studying our remains trying to figure out how we died off so quickly, just as we do with the dinosaurs.
 
  • #15
Heh, myngoblin do you believe life is inherently self-destructive then?
 
  • #16
humans are already killing each other... so i guess... like the giants in harry potter... we will be our own doom... whether it is nuclear warfare, man against man deathmatch, environmental disaster (global warming, ozone depletion whatever), new diseases (what with all the mutation... it's not unlikely), or whatever... humans will make humans extinct like we have many other species...
 
  • #17
The sun is turning into a white dwarf, a black hole will suck the galaxy, the final version of the string theory will help us fleeing..
 
  • #18
I think human life, and much animal life, will end when we've simply buggered up the environment enough. Either that or a comet or meteor or whatever does for us what it did for the dinosauruses. Enough humans would probably survive a nuclear disaster to maintain the race. Someone would win the death match, and so survive. If that was a woman pregnant with twins then, while we may get a bit stupider, we may well carry on for a bit longer. There's always someone immune to something, so I doubt disease will do it. And deserting planet Earth won't end human life, just human life on Earth.
 
  • #19
It won't end.

We will keep it going until the universe is petering out, and by then we will have
figured out how to start new universes.
 
  • #20
I think it is most likely humanity will eliminate itself by using our own weapons. The threat of nuclear weapons is ever present and could be catastrophic in the wrong hands(anybodys hands for that matter). Biological weapons created in the labs of rogue terrorist groups could be used to kill millions of people at a time.

Humans seem to be more likely to use their intelligence for some destructive purpose than good. This has been demonstrated throughout history as ever more destructive weapons have been developed for the sole purpose of killing more and more people.

God will turn humans into armless and legless blobs of flesh because we don't use our arms and legs for anything other than working out and looking good:!) . Then we'll be known throughout the gallaxy as slugs. Soon, we'll develop a slime trail and will no longer be able to drink beer or use salt on our fries. Watch for it. :rolleyes:

I think we will die from a nuclear halocaust. It would only take one bomb to start a nuclear war, and there is no theoretical limit to how big a nuclear weapon can be :bugeye:
 
  • #23
Why can't I pick more than one of the choices? :mad:
 
  • #24
I don't much care which of the options actually occurs as long as I'm not sung to death by Barry Manilow! THAT would be TORTURE! :smile: :smile: :smile:
 
  • #25
I think it will be one of the following:

1). A meteor or comet impact
2). Supervolcano
3). Giant space guppy eats planet

I think the best explanation was given by the late Douglas Adams. The Earth will be destroyed by alliens for the pourpes of building a hiperspace bypass .

And neither will The Simpsons. :cool:

"...And on the pedestal these words appear:
My name is Ozymandias, King of Kings,
Look on my Works ye Mighty, and despair!
Nothing beside remains. Round the decay
Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away."
-Shelley

The universe will end at the Coming of the Great Handkerchief.

Sun will grow to red giant -- the end.

This kind of question is all to common
