I appreciate that you made the point that most people don't consider when talking about space colonization, that we can spread life. Not just us. Life in general. Also, humans are not the first species to threaten life on earth. Look up the great oxygenation event. The first photosynthetic plants sucked CO² out of the ancient atmosphere and pumped toxic reactive gass(oxygen) into the atmosphere, causing a massive extinction event and for the planet to freeze over

@@edthoreum7625 antinatalism is the philosophy of someone who has no long-term vision. Say being complicit in the production of new life is a moral evil. That doesn't mean "I shouldn't have kids," it's "kids shouldn't be had." But it's worst than that- not only is it the case that you'd have to convince every human to stop having kids, this moral conundrum applies all the same to every living thing! And not just living things, but anything that can receive positive and negative utility. In other words, building a programme to play a Mario game that has a reward function is morally wrong. You might as well say _entropy_ is morally wrong for all the good it does you. "Self-arranging things should be made because they inevitably experience conditions sub-optimal to self-arrangement" is the basic argument, and it's delusional.

The higher concentrations during dino times lead to massive plant growth and no polar ice caps, as well as frequent massive devastating shifts in climate as far as we can tell. It would be nearly impossible to send the amount of CO2 needed to return to below 350 ppm CO2 into space, but a cumulative approach with other on world sequestration methods could do it. The most promising way to sequester CO2 on earth is by creating rich topsoil, which to me does beg the question, why not create soil in space for offworld colonies.

Bush was right, Americans don't want to change, this gross consumerist lifestyle is not negotiable. that's why Aliens and space colonization are pushed so hard, it seems to work pretty well with a large part of the American public. like a lie they would accept unconsciously in order to accept the fact they won't change, and that it's destroying Earth and Humanity's future. lies to keep the statu quo intact. but yeah, cool 3D renders I guess.

Preserve biomes in O'Neil cylinders

I love the idea of uplifted animals / AIs coming back to earth to liberate the humans on it from a crappy tyrannical ancient style government.

Really glad you are taking a more near term focus. All our attention and energy needs to be put onto making humanity multi-planetary as soon as possible, and colonising the solar system as rapidly as possible. What happens after that is more speculative, and that's interesting to wonder, but I feel there is a genuine practical urgency to this goal, for the very survival of the species.

Are there any super bunkers in existence? If not, where should they be located? I recall something was installed at the new airport outside of Denver and there is a very strange artwork over the entrance to it.

I can fanatically not confirm or denial of the existence of a bunker under the runway of the Denver airport for our political leadership

I think Sweden has enough bunkers for it's entire population to ride out a short term catastrophe. Might have been a different Nordic country

Most of them are military in nature and are primarily intended for nuclear war, but yes they exist.

@Issac Arthur 8:35 were you talking about Venus, or San Francisco? 🤣

New questions and tangents are usually deeper like how else can I make fire.

Happy Thanksgiving

Another great topic Isaac. Now for JMG's video over on Event Horizon

Damn right Isaac I have been trying to tell people this since hell 15 years ago!

Well said Isaac 💯

I've always been a fan of Chris hadfield's sons work. Rare earth. Sh*t makes you cry.

Good sound.

Ohhhhh i can't wait for "Escaping the Galaxy"!!!! That sounds very interesting

I wish I had your optimism. I'm afraid human greed is going to keep us on the Earth until we go extinct.

Have you heard of the grabby aliens hypothesis for why we don't see aliens?

I love this title - didn't watch - instant like. I'll come back to it later

If we have the technology to colonize space, we have the technology to fix Earth

one of my favourite topics to non technological civilisationists btw that maze was a dead end lol

I bought nebula simply to pay back in any form some tiny part of the truly staggering amount of effort and knowledge this show has given me. But i do have to note that clunky UX is still very much the case and i hope it improves more.

Yeah we have to do both. Solely focusing on either option will result in us running out of time I think. Space exploration is the great R&D accelerator. On earth the implementation of any tech is always lagging a decade behind anything that could be done, so companies can cash in on incremental improvements.This is also incredibly resource wasting.

@Darryl Revok that is more of a good long term goal than something we can feasibly do within the next 2 or 3 currently normal human lifetimes. At the moment we need to prioritize stabilizing civilization and our ecology with space industry being limited to being mostly supplement for practical reasons so that we can reach that point in less than 300 years.

I love the unruly children analogy

Still waiting for Isaac's take on string theory and M theory!!!!

do you think magic like scarlet witch or dr strange use from marvel is just advanced programmable matter like nanotech, picotech or even femtotechnology with maybe different physical constants due to being from another universe. because nanotech can manipulate any molecules, picotech and femtotech can also manipulate any atoms and sub atomic particles

The Crocodylamorpha body plan has been stable through seriously deep evolutionary time. This might indicate it would appear à la convergent evolution in extraterrestrial life as well. I think this is the kind of First Contact we could reasonably expect when the toothy aliens translate r/FloridaMan en route to first Earth visitation.

As astronomers and other scientists become more vociferous when asking the question "Where is everybody?", I think the answer is staring us all in the face. Any species that evolves to the point where it is very good at exploiting resources has not yet evolved to be very good at conserving and husbanding resources for the long term, so they eventually collapse and the civilization does not survive. They simply disperse and disappear, like some past cultures on earth that disappeared after they used up all the firewood.
