the huge caveat is why being multi planetary (within 250 million years) is necessary. There are hundreds of other things that could take out the human species by then.

😅So true!

honestly, we could technically carve out lakes from the sea across africa, and make a huge portion of the land liveable... not to mention the addition water vapour could make clouds in the area...

Worrying about things on that time-scale is insane! If humans survive the next few thousand years, we'll be multi-planetary. By the time the continents shift substantially, we'll either be long extinct, or widespread in this section of the galaxy.

I hope my browser bookmarks still work so I can come back to this video once we have Pangaea Ultima.

If we can settle other worlds and make lifeless rocks habitable, then we can easily make anywhere on earth perfectly habitable. Stop drinking the Musk Kool-Aid.

This isn't exactly true. With earth you have to deal with World-Wide politics. Take countries in the Sahara desert for example. They may not let you terraform those areas for new populations. Same with Antarctica. No country can truly lay claim to it, and any attempts by a company to terraform it would be met with resistance. You also have to think about world-ending events. These can take out the whole planet in a single sweep, and being multi-planetary prevents this from happening. terraforming other planets is actually easier politically speaking.

​@@dackg.2918 Firstly, politics will be anywhere humans are. Already there are space agreements which would make colonization and laying claim to stuff that supposedly belongs to all of mankind difficult politically/legally. So getting humans to work together to fix earth would be a lot easier politically than getting humans to work together to turn a dead world into a garden world. Additionally, earth is large enough and at an orbital distance where it wouldn't require any additional tech to make it habitable. We wouldn't need to create an artificial magnetic field, increase its gravity, change its spin rate, increase its atmosphere density, add or block light, etc. Everything here is already perfect for sustaining life on this planet. Now if your plan is to use domes on Mars or floating cities on Venus then firstly, why not just use space habitats around earth or the moon, and secondly, why not just build domes on earth? Both of those would be a lot easier to do than building them on or around another planet. I'm not saying we should eventually expand to Mars and Venus, but the motivation for that shouldn't be that we've fucked up our homeworld. Since that reasoning makes no logical sense. As for stuff that'd destroy earth but not another planet, well asteroids are about the only thing with a high enough chance of doing that. There are other threats (nearby supernova, war, rogue blackhole, planet, star, etc, passing through the solar system, vacuum decay, God getting bored and shutting down the simulation, etc) but they'd all have a high chance of destroying other planets too. A lunar base or array of space stations around earth would be sufficient to protect us from anything that'd destroy just earth. And if we have the means to send colony ships to Venus or Mars then we've also got the means to destroy or redirect anything that'd threaten earth. So again, I fail to see this as a valid argument for colonizing Mars or Venus. The only reason to colonize any world is for the fame, tourism, and science. Otherwise asteroids are likely to be a better option for raw resources, space habs would be a better option for living area, bunkers on earth or the moon would be better options for preserving our species. There are a few really cold moons which might be awesome for supercomputers, but aside from those 3 or 4 reasons, I really don't see much point in sending humans past the earth/moon system. Robots can bring asteroids back to earth's orbit and you don't need to keep them alive with food, water, and air. Sending people is purely a vanity project not a necessity.

But do we really? I mean, thermodynamically speaking, we're not eternal. Why don't just accept a peaceful extinction instead of try and keep perpetuating ourselves and our suffering?

I think this would stem into several discussions including the meaning of us living as a species. Are we bringing the world and ourselves any good by us living? Or is it overall better that we are not.

I think most of humanity will succumb to extinction, but tiny tribes of the survivor types will be willing to use science and adaptation to live on way beyond their expiration date. For those who are willing, we'll become a niche artifact of evolution; one of the few endangered species to protect and scientifically intervene on their own behalf.

Pangaea Ultima is going to happen way, way before the Heat Death of the universe.

I'm not entirely sure why going multi-planetary would help. After all, Mars and Venus our closest neighbours are −63 °C and 467 °C respectively, it would be easier to colonise the neo-pangean interior using water desalination, or some other new technology, than it would be to create a multi-planetary society.

Colonization is the wrong word to use, as continental drift is extremely slow and we don't suddenly wake to a different layout of land. Adaptation, or the lack of ability to adapt, is the question. It's also not something discussed much in the face of climate change...we're still talking about fixing the climate and returning to "normal" (there never was a normal) rather than acceptance that things are shifting beyond our control.

Why can’t we just cool down the earths mantle and core I like the shape the continents are in. Humans should control the tectonic plates with big vibrators or some new technology. It’s probably an easier technical feat than colonizing planets. I don’t know the mechanism to do it but it’s probably possible 🤷
