How Long Can Humans Outrun Extinction?

In a few million years, we’re going to have to leave Earth if we want to survive. But how long can we actually outrun extinction before the universe becomes uninhabitable to us?

[@CarFreeSegnitz]

2:42 repeated asteroid flybys The best way to move Earth: fleets of giant spacecraft whose orbits are pumped up with solar sails and engineered gravity passes past Jupiter & Saturn. Steal angular momentum from the giant planets and deposit it into Earth. The larger the spacecraft involved the bigger the helpings of angular momentum can be transferred with each pass. Such a project to move Earth into the asteroid belt would "only" take 40-50 million years. Ultimately, though, we may conclude that planetary surfaces are not very efficient at providing habitat. Spinning habitats are about a million times more effective at providing habitat pound for pound. And habitats are wildly more relocatable than planets.

@Virtual Sky Tate Not True humankind with his present technologies can do a great amount of damage to the life on the planet perhaps even wipe it out except for tardigrades ;-), but we can't destroy the planet. To break the molecular bounds between all the thousands of miles of rock requires magnitudes more energy then humankind has control over. Think about it Earth survived the late heavy bombardment , millions of years of small and gigantic asteroids falling down from space almost daily. Some of them containing more energy then all the atomic bombs combined.

[@dplocksmith91]

@Virtual Sky Tate I'm sure we couldn't *destroy* the biosphere. Life is pretty damn durable, almost as much as the planet itself. We could, however, render the planet inhospitable for most complex life. Basically, life after the worst effects of global warming is going to be incredibly harsh, and I don't want that to happen, so we have to fix what's happening right now. I live on the coast, and my whole state will definitely be underwater when the ice caps melt. Though considering how most of the world views Florida, they probably think that's a good thing.

[@abram730]

@@dplocksmith91 "I'm sure we couldn't destroy the biosphere." We are and we will all die of hypoxia as oxygen runs out. Acidification of the oceans from global warming is killing off photosynthetic life in he oceans and they produce 70% of the O2 we breath. A sharp non-linear decay in O2 levels has begun and the extinction clock is ticking. Killing off 70% of human life will be required if we don't reverse global warming quickly.

[@medexamtoolscom]

You're an idiot if you think that. What's going to kill us before the end of the year? Crissakes it's July, we're already more than halfway through the year, extinction had better hurry up if it's going to get us by year's end. But this millennium will be the last one almost certainly. Just look at the number of existential threats. The 2nd half of the 20th century was spent by everyone shivering in their boots worrying about nuclear war. The odds of it happening in those 50 years was PROBABLY better than 50% and we literally beat a worse-than-cointoss-odds great filter. But you know what that means? That the odds are probably at least 50% per century just from nuclear war alone. Which means surviving for 1000 years is a coinflip followed by a coinflip followed by a coinflip followed by 7 more coinflips and extinction happens if they don't all come up heads. And now unlike the 20th century, it's no longer the only existential threat. And others will emerge, the longer humans are around the more there will be. My money is on a genetically engineered supervirus, basically airborne rabies. Something 100% lethal, with a 30 day incubation period before symptoms and only a day or 3 before it is contagious, so that the whole world can be infected before anyone knows the disease exists. And if that doesn't happen, there will be others, things you can't even imagine yet.

[@asahmosskmf4639]

I think it was a joke. Plus if the chance of nuclear war was a coin toss each year, we would have been dead long ago. World War 2 used nukes, and that didn't destroy the world. Maybe 2 cities.

Isaac has some interesting ideas, but his solutions are flamboyantly pie-in-the-sky and don't account for the fragility and interdependence of our current civilization, and don't adequately account for the human stupidity element.

That's also one of the ideas for terraforming Venus. :) Get it not only cool enough for humans to live on, but SUPER cold, so that all that carbon dioxide _snows_ out of the atmosphere, and THEN start warming it back up, with a more human-friendly atmosphere this time...

The 'Last Question' is very applicable. Excellent short story.

[@didiodulaw7417]

Channel name is SFIA. He also has a whole series on the topics mentioned in this video.

[@robinchesterfield42]

And so does Isaac Arthur!...think of that story, that is: he's mentioned it a few times in his videos. Especially in one of the "Civilizations at the End of Time" ones, which this really makes me think of. (He's also actually named after Isaac Asimov!) Now, who IS Isaac Arthur? He's a KZbinr who does these awesome thoughtful, long, detailed videos about all kinds of science-fiction concepts, what would and wouldn't work about them based off of what we know currently about actual real-life physics, how human civilization/culture would react to them, etc. I first found out about him from a V-Sauce video (and that's also how I found "The Last Question", come to think of it) so... Badass, BIG-thinking stuff like black hole farming, GINOURMOUS megastructures that make the Earth look like a speck, galaxy-spanning civilizations, virtual transhumans, planet-wide cities, immortality (he has a PLAYLIST called "Existential Crisis", lel) and timelines that could eat the current age of the universe for a light snack are just a few of the things his videos talk about. If you like high-concept sci-fi stuff and have some time, I highly recommend you get a snack and a drink ;) and try out his channel.

[@ariadgaia5932]

Oh! I have this hypothesis.. [..that I recently learned some physicists are actually researching~ :3 ] ..that the "Big Bang" was actually a single super-supermassive black hole that had taken in too much anti-gravity (since not even light can escape the gravity of a black hole as space is curved to the point that EVERYTHING falls into them) which caused it to "explode", or.. more like rapidly expand as the force of anti-gravity overcame the force of gravity within the black hole~ Much like how massive stars explode at the end of their lifespan, I believe black holes do the same! I mean.. think about it.. The universe supposedly started from an infinitesimally small point, right? What are black holes? Unimaginably dense objects compressed into an infinitesimally small point! What if black holes have a life cycle similar to stars & over 10^30+ years eventually explode to fill their locality with all of the energy needed to begin a new universe? Just as stars take lighter elements & make heavier elements in their cores, black holes are the reverse.. taking all elements in & breaking them don't into their smallest component, which for now we believe are quarks (I think)! Yin & yang, y'all! If so, we'd have new universes starting with new "Big Bangs" all over the place & at different times creating a multiverse! Sure- Humanity may not survive to ever travel to nor witness such new universes being born... but I feel that the multiverse has no end nor any beginning~ ^_^ Just different points in time where new universes are born while old ones die, just like every other cycle known to humanity~
