Quand tu vois la descriptions des anges dans la Bible, surtout pendant l'Apocalypse, tu te demande d'où vient cette image de petit bébé volant dans les nuages.
Les anges, ils sont plus proche d'Evangelion que des bisounours...
Well, most of those drama comes from misinterpretation of what is a gender and what is a sex. Sex is biologically defined (most of the time). It is a medical data, a fact. You are either a male, either a female, and a tiny fraction of the population where it is not so well defined.
Gender is whatever the fuck you want. It is more like political, religion or philosophy. You feel closer to a certain group, a certain way of living your life or not.
Unfortunately, I'm now convinced universe is too huge and speed of light too slow to reach step 3. A best, we would have step 2. For step 1, if life exist outside of observable universe, it's like it doesn't exist at all as it's just physically impossible to detect it.
My current belief is life is so rare we are the only one in observable universe. Maybe there are few other outside of observable universe, which is much bigger, but as I said, it's like they don't exist at all.
Do you have sources or books recomandations ? I'm a big fan of hard Science fiction and scientific vulgarizations. The books from Hawkings "a brief history if time", "universe in a nutshell", etc... where mind blowing.
I agree, I do an easy extrapolation of Okam razor. What I try to say is that the argument that universe is big so there must be other life form doesn't make sense to me, and it may even be the opposite.
Assuming there are other life forms because universe is big implicitly assume probability of life apparition is higher than maybe 10e-20 per solar system. But even if our universe seem huge for our tiny brain, it is insignificant when dealing with combinatory probabilities. We can quickly reach 10e-100, 10e-1000 or even smaller probabilities just by adding some simple requirement. And as we have no ideas of the value of Drake equation, we really have no idea of probability of life apparition. Maybe this probability is so small that is it a miracle that we exist in a our "small" univese.
Life did depend on other stars. At the very beginning, there were only hydrogen in space. Then 1st generation of stars built helium by fusion then explode, creating second generation of stars that create heavier elements and so one.
Life really couldn't appears in a single star universe, because there were just not enough "atomes factories".
OK, now the matter is here, other stars might not be required anymore. But stars have a very limited life time. Sun will explode in ~5 billions years, so do other stars. Other stars will born, but this is not unlimited. Once every atoms will be fusion into heavy elements, there just won't be new stars anymore and univers will enter in its dark era. This should happen in ~100 billions years. Then there will just be blackhole during 10e100 years, and then very slow decay during something like 10e(10e(10e10)) years. At least, it is one of the currently admitted theories.
Universe is sparse, but panspermia is a valid theory, right ? I admit I just briefly read the wiki page about it, I didn't dig to check if it is a valid theory or not.
Regarding anthropic principle, I thought that weak one was about time and space in universe (earth around the sun and not another planet) and strong one was about the whole physic (our universe with its physical constants). Am I missing something ?
You exactly spot it. "any scenario can only arise from the simplest system that could cause that scenario to arise". Nature is lazy and don't like spending resources for nothing.
Again, it is my opinion, and I posted it here to challenge it.
If you have examples or argument against it, where scenarios did occured in over complex system, i'm interested 🙂.
Sure, all of this should be taken with "current state of science". But if we start saying "we don't know anything, we may be wrong", then we just cannot discuss about anything.
Estimation of size of universe vary depending on the models. I've read it's ~10^80 atomes. Let's makes it 10 times bigger. It would gives 10^81, what a big deal. One billion time bigger, 10^89. You see what I mean ?
But as I know there are currently no scientific model that suppose an infinite universe.
Yeah, clearly there are no scientific evidence, that's why I post it really as an opinion.
What I understood from anthropic principle and other sources is, either our universe has been fine tunes, either it is one among billions of other universe.
If some "god" fine tuned the universe for life, he would have not over design it, and would have created the simplest universe where life can live. Well, that's what I would have done 😅
If our universe is just the one over billions where physical constant are compatible with life, statistically, simpler univers would appear first. The more complex the universe is, the more complex it is to makes it compatible for life. It life can appears in a universe with only 3 constant and one galaxy, I think we would live in this universe instead of ours.
Regarding current values of physics constant (speed of light, G, mass of electron, etc...) It's statistically not possible that our universe just appears like this. Either it has been fine tuned by some "god" to make life possible, either there are billions and billions other universe with differents constants but where life is not possible (see https://en.wikipedia.org/wiki/Anthropic_principle)

Well, I think so. My argument can be summarized as: things happen in the simplest system that can handle them.
Be carefull. An infinite sum of values doesn't always give an infinite value 😉 And even if universe huge, it is far from being infinite.
When dealing with probabilities and combinatory, you can reach crazy values.
As example, there are more 128bits RSA keys than there are atoms in the whole universe.
And if something has a probability of for ex. 10e-80 to happen, you'll need a shitload numbers of universe to makes it happen.

/s What was wrong with wheel ? Machines can go faster than human since a century or two.

You have sources or argument ? Lots of scientific studies shows that glacier do carve solid rocks.
Yeah, as long as you use it as a vim container.
Well, it'a an opinion until it can be proven or disproven.
I thinks there are 3 level of life discovery:

Thanks, I'll have a look then.

Is it a serious documentary or some history channel Bullshits ?

Actually, life won't be possible anymore in some billions of years. Not enough stars anymore, too much spaces between galaxies. Too Much darkness 😢
We are in the very brief bright moment of the universe.
