>the sun only has a billion years left
nah, sun has many billions years left. the habitable earth without human intervention has billion years left based in currect models of gradual sun luminosity increase. but if humanity survives until then, it won't be much of a problem to limit a sunlight coming to earth, especially not if sun would be turned into dyson sphere.

It blows my mind that people can't realize this simple fact. Funnier still are people who blow Elon, not realizing he's just a scammer. Mars by 2022 or something. Moves 2 years every 2 years, forever.

People don't realize just how hard it is to have something as seemingly simple as a small outpost on Moon. Which we will very likely NEVER see during our lifetimes. Probably never. Now that most of the thinking (white) population is being replaced with jeets and niggers as cheap labors and white people not having children, the future of humanity is either Chinese in space (also extremely doubtful) or just deterioration.

Cycles of civilizations and all that.

For most people, I would guess that it is probably astatine; it is the least stable element in nature (francium is less stable overall, but astatine has a shorter average half-life if you're only considering naturally-occurring isotopes) and occurs as an infrequent decay product a couple of steps down from radon in the uranium series

So recently I got my first taste of existential dread/ eldritch horror. It was the theory of how universe might end and how it would result in nothing ever happening ever again, universe turning into a bowl of roaming particles that doesn't react to anything. Nothing will ever happen for all eternity and it kinda scares me knowing eventually it'll all end, existence will cease to be. It being billion even trillions of years away doesn't ease me since this possibility exists.

Don't worry anon, gravity will still exist and will eventually pull all matter back into a singularity. A singularity which will then produce a big bang with the same properties which resulted in you, given the identical mass and constituent matter. You've experienced this existential dread 37 septillion times by the way, and you'll keep experiencing it forever.

>>16975323
Your theory ignores the rapid development of AI. Reducing the population will not create a perceived "need" for human development from the upper classes. They will just try to backfill with AI and if it fails, they still win because they control more resources.

Instead, fix labor laws, add accountability for corporate leaders, and give incentives for innovation in industry.

the expansion of space, if it exists, which it doesn't, would be whole, such that objects also increase in size, and such that all increments in size, uniform, would be indeterminable and undetectable; which doesn't explain movement in space, because movement in space explains movement in space, rather than a fundamental non-uniform vague lazy rule of the universe that *empty* space expands while occupied space does not.

Humans evolve to do exactly this in All Tomorrows

How come just getting a good night's of sleep and practicing to solve similar logical/pattern recognition tests than those IQ tests use can make the difference between an average and an above average result, yet "IQ tests can't be cheated"? And if practicing similar problems is considered cheating, why would it? Intelligence is transferable across different learning contexts after all, and we need to be familiar with a certain type of thinking to solve similar problems

you're referring to pi, so the assumption is because digits of pi have been calculated by computers, therefore human brains can always correctly predict and comprehend any next digit of pi.

I'd just like to interject for a moment. What you're refering to as π, is in fact, R/π, or as I've recently taken to calling it, R plus π. π is not an number unto itself, but rather another free component of a fully functioning R number system made useful by the properties of R, including continuity and denseness, comprising a full real number system as defined by Cauchy and others.

I've been thinking about this lately. If we look at certain sexually dimorphic traits in female humans, especially ones that are considered sexy in girls, they're also what makes meat taste good. For example, the female body has thinner skin, lower collagen density, and even a less rigid collagen bond structure. That's responsible for the soft body quality in attractive girls, and it also makes meat more tender and delicious. Women also have less muscle (therefore less tough meat) than men and a higher normal body fat percent range. Less of that fat is visceral fat which would just be gross excess fat that doesn't help the quality of the meat and more subcutaneous fat and intramuscular fat. In particular, intramuscular fat is the source of marbling, which results in juicier, more tender meat. Girls also have more fat concentrated in the breasts, thighs, and butt, which are both sexual points of interest in the female body and the main body parts that would be eaten for meat. Looking at diets, (stereotypes and reality) girls eat more plants (fruits and veggies), carbs, and sweets and less meat compared to guys, which is the exact diet that makes animals taste better. It just seems that biologically and culturally, feminine means tasty.

I wonder if anyone else explored this question. This is the only thing I found.
https://kirstenkoza.com/scoop-scandal/contemplating-cannibalism-male-female-meat-tastier/
The conclusion is that while female animals taste better than male animals, it's because of the male scent gland which humans don't have, but I find that answer unsatisfactory because of the traits above. And humans do have scent glands, don't they? Like the apocrine sweat gland? Science shows that male body odor is stronger and more unpleasant than female body odor. If you look at practices of cannibalism throughout history, you'll see a pattern of female flesh being more prized than male flesh, so there must be some truth in it being tastier. Does this make sense?

>>16972930
Sorry but you completely lost me now. I just don't buy that the reason feminine qualities are similar to tasty meat is that our preferences were shaped by breast feeding. There are evolutionary reasons for why our tastes buds are the way they are that go back far before us and are too intrinsic to be arbitrarily determined like that. In the first place, breast feeding is not the same as eating flesh so it's not the same taste.
