Is there a dumber meme than "rare earth?"
There was literally two books that came out that spouted fringe theory and unfalsifiable speculation and now everyone thinks its the scientific position on life elsewhere.

Fermi Paradox is not science. Kardeshev is not science. These are assumptions. The scientific position is that there likely is life, even intelligent life, elsewhere until proven otherwise.

That's bullshit. You can't claim the "scientific position" (whatever that means) is that something for which there is ABSOLUTELY NO EVIDENCE likely exists in the universe. That's like saying there are horses and there are horns therefore there are probably unicorns.

it is much more likely that human existence is the opposite of basic life expectation standards outside the Earth by an occams razor approach that human existence is basically opposite than any other discoverable life already present on Earth.

If aliens exist, they're probably more animal-like in nature than human-like, and they would probably be intelligent enough to want absolutely nothing to do with humans because of how goddamned weird humans are.

You're right. Its far more likely that in a quite probably infinite universe that amino acids formed long self-replicating protein chains only once, here. Not only is that probably happening everywhere it can, I would bet anything that if we looked hard enough around deep ocean vents we would find times it happened completely unrelated to DNA that just never "took-off."

Not sure you can even used words like "likely" here, it's just unknown. To get a rough idea of the probability we would need some sort of estimate for the probability of finding all requirements for life as we know it (not just some of them like water and heat). Of course there could also be other types of life but we obviously can't estimate the probability of that either.

Our star is one of the best suited for life there is. Big enough that it doesn't destroy your atmosphere but also small enough to allow life to thrive for billions of years.

Here's my opinion on Aliens

they don't exist

if they appear and or we make contact with them then I change my position and they exist

but until then they don't exist

for the sake of every Alien lover out there you better hope that they appear before you die or you will be wrong for the rest of your life

Isn't it? It's just noting that despite the high calculations for life in the universe, we see no evidence of it. It's not saying there is no life, it's just a problem to solve.

Plenty of animals act like humans. Birds like to sing, dance and play pranks. Lizards like to tan in the sun. Dogs even have similar social structures to humans.
>>14835022
>in a quite probably infinite universe that amino acids formed long self-replicating protein chains only once, here.
Our observable universe is only ~90b ly in diameter and we will never see beyond ~120b ly. We can also only travel within ~16b ly. There is no telling how large the entire universe is but any statement about anything that's not causally connected to us is pointless since even the universal constants there could be totally different.
Now, to get back to our observable universe, we have roughly 200b * 300b = 2*10^11 * 3*10^11 = 6*10^22 stars. Our light cone is rougly 4% of that so 2.4*10^21 stars. If the likelihood of intelligent life developing is less than 1/10^21, we could very well be the only intelligent form of life. Hell, if the chance of life is totally at random, it could be as low as 1/10^~50 so even us existing is HUUUGE fluke.

Your argument boils down to UNIVERSE BIG THEREFORE aliens but you forgot about SMALL PERCENTAGES.

Yes, and when we apply human reasoning to civilizational development and see that nothing so far matches what we would do, right now, in 2022, such as star harvesting, we call that evidence of absence, when it may just be fallacious to base advanced technology on what we consider to be likely on Earth in 2022.

We're throwing the baby out with the bathwater when we presume ourselves a freak occurrence simply because evidence doesn't match our models. Its an anthropocentric fallacy.
I don't have an agenda. I actually don't care either way. My beef is with our hubris. To say "well they don't do exactly what we think they would do at least in our small window so... no life anywhere." We're assuming Kscale nonsense and VN probes and that is just wildly premature.

It's not a fallacy because the Fermi paradox simply states the difference between what we would expect (tons of life, signals, etc) and what we observe (silence). It makes no statement on the matter. It's just a question to be investigated.

Wherever I look I see signs of human activity, even in the most remote areas of the world. If an intelligent alien civilisation (who statistically must be dozens to hundreds of millions of years more advanced than us) does exist, it is very likely we would see signs of their activity even from here on earth.
>such as star harvesting
I'm assuming a head start of few hundred million years will eventually give you access to such technologies since they are physically possible to begin with. And they make sense, considering matter and energy are limited in our light cone. Even a smaller structure would be detectible.
>And one very good reason to think it is possible.

>Like I have said, for this to be so painfully unique defies logic.

The Fermi paradox makes no statement that there is no extraterrestrial life. It only describes the disjunction between what we expect (lots of life) and what we see (no life). Again, it does not say there is no extraterrestrial life.

There are also plenty of g-type main sequence, but assuming we even need that is again applying our circumstances to the formation of life at large.

By rule out I think you mean that people who read about the paradox will think it means there is no extraterrestrial life, is that correct?

Life definitely needs an atmosphere. There's just too much deadly stuff flying around in empty space.

The most efficient energy source you can get is probably black holes followed by slow fusion. Considering the universe is still far too hot to seriously consider black holes, that leaves amassing as much hydrogen and other matter as possible to slowly use it for fusion. Yet we are still capable of seeing stars and there is no large scale star mining going on around us.

Right and to also answer >>14835217
To use our example as the one time this event occured, especially if its occurence was forged by no more than the brute laws of physics, is premature. I understand one example does not an inference satisfy, but I also have severe trouble believing uniqueness arguments based on human understanding of probability, understanding of energy generation, want for real estate, wanderlust, and other things that are quite possibly uniquely Earth-like features.

I'm well aware other lifeforms will have to play ball with the laws we (partially) understand, but who knows even philosphically where non-earth lifeforms are at. An "advanced civilization" may be one that keeps its numbers small and peacefully awaits the death of its star. We base nearly all specualtion on what we would do, current year, current level of understanding, and given the distance in space and time between possible civilizations, that's wildly premature.

>>14835224
>As I said, up to 15% of stars are potentially habitable
Even if that figure is correct its only correct in light of our current understanding.

>Life definitely needs an atmosphere
And a magnetosphere which until proven otherwise, I have to guess hang around a countless number of celestial bodies.

>Because you are autistic.

This is again our limited view on the wants and abilities of sufficiently advanced civilizations. Large scale mining of stars is an en vogue idea (goddamn did Kardeshev muddy the waters). To think it holds for all-time is probably wrong.

Based on what we know, but we also know there are properties we have yet to understand. Just as a bygone generation knew you could tease energy from coal through a chemical reaction, we can take the same lump of coal with our current relativistic understanding and know that in its mass is bound-up an astonishing amount of energy. Are we to think there are no more revolutions of understanding in store? That nothing like a small local white hole of sorts is conceivable?

Why still don't know why anything is. We're stuck philosophically, only observing how the matter and energy we were left to work with plays ball; What the rules are, and those are of course hard facts, but imho likely not indicative of all there could be in potentiality.

Spawns a planet that takes ~4 billion years to develop "intelligent" life, which seems likely to be a very lucky roll.
Has <1 billion left in it before it makes life on the planet impossible.

Red dwarfs are actually better candidates. Big enough magnetic field coupled with the right distance, or be a heavy moon around a large planet with a giant magnetic field and you're good for exponentially longer than you'd be around any yellow dwarf, and they're much more apt to spawn rocky planets.

>> No.14835591

>>14835161
Habitable zone planets seem to be around nearly every star where we can see them, and Earth-like planets seem to be common enough even in the even narrower scope in which can we detect those. So the odds shouldn't be nearly so narrow.

Still think the great filter is a hard population cap, so civilizations that survive to space fairing maturity do not spread at infinitum nor have an ever-increasing need for energy, thus they leave a minimal footprint. Those that fail to make that adaptation eat all the resources on their worlds before they can escape them.
