    Fun fact: this is how they separate oxygen, nitrogen, and argon from air. You cool it to a liquid, and the. Slowly heat it back up. Nitrogen boils off first around 77K, then Argon around 83K, then Oxygen at 90K.

    I find this so cool, even though it’s like “oh yeah. Just like distilling alcohol or petroleum”… But… Like super cold…

    We can also prove its existence scientifically. We can detect by testing for it. We can chemically react it with other elements. There are lots of things we can’t see with our eyes but we know exist through scientific study.

      I almost buy the philosophical argument that there must be a first mover, but I can’t understand the incredible leap of faith people make to have such specific beliefs. Like how did we get to the point of “how many angels can dance on the head of a pin?” and prosperity doctrine wackiness?

        Honestly, the first mover argument just looks like “turtles all the way down” to me. It explains nothing, because it doesn’t even care to explain this first mover. It’s just one more turtle.

        Hence, if the correct answer is “we don’t know”, we don’t need the leap of faith to a first mover we know nothing about, we can just say “we don’t know” and they don’t either.

          Same issue with the big bang, since we don’t know what created it. I personally believe that God is the universe. The universe manifested itself…somehow…and to me that makes it as close to God as we can get. I hope that the universe is conscious, and that our consciousnesses goes back into the big thing at the end. My evidence is experiential; an excellent acid trip 😉. I do wonder what atheists experience when they trip…

      “I’ve begun worshipping the sun for a number of reasons. First of all, unlike some other gods I could mention, I can see the sun. It’s there for me every day. And the things it brings me are quite apparent all the time: heat, light, food, and a lovely day. There’s no mystery, no one asks for money, I don’t have to dress up, and there’s no boring pageantry. And interestingly enough, I have found that the prayers I offer to the sun and the prayers I formerly offered to ‘God’ are all answered at about the same 50% rate.”

    The funny thing is that we actually see oxygen, but as a gas it’s so dispersed that it’s almost fully transparent.

    In theory, if you could press enough air into a tight enough volume (like, say, 1 cubic meter of air into a 1 cubic centimeter), you’d get a similar result.

            I’m saying if the atmosphere was smaller, scattering would be less and blue colour may not appear. So the blue colour is not because the atmosphere is “not entirely transparent” like the commenter said, but because there is enough of the atmosphere that the scattering effect is prominent.

              And yet, if the atmosphere was fully transparent, there would be no scattering of light. The blue colour is an effect of the amount of air, but there would be no colour at all if air was fully transparent.

                That is funny. According to you, for a medium to be called “fully transparent” there has to be no scattering of light. By that definition, water and air are not “fully transparent”. I’m not sure if such a material exists that doesn’t scatter any amount of light.

                  That seems to be the scientific consensus, yes. It’s like friction, no material is truly frictionless just like no material is truly completely transparent. The ocean gets real dark once you get deep enough which does seem to suggest that water is not fully transparent.

                  Correct. The only substance I can imagine being completely transparent would be some kind of dark matter. Everything else still interacts with light, no matter how little. Even deep space isn’t completely transparent, as we can tell what elements exists as interstellar and intergalactic dust from spectrographs.

                  Atmospheric absorption spectrum - We can see (heh) that the atmosphere is completely opaque to most electromagnetic radiation before scattering. Only some microwaves and short radio waves can pass without any absorption.

                  Atmospheric transmission spectrum - We can see that not even 60% of visible light is transmitted to the surface directly due primarily to scattering losses. That scattered light is why our sky is blue during the day and orange at sunset/sunrise. Mars’ atmosphere is orange during the day and blue at sunset/sunrise for the same reason.

                  The physics of light scattering doesn’t change based on how much atmosphere you have, even a single particle can scatter light. In fact, the physics of scattering is based on single particles, and the particle size is what differentiates Rayleigh scattering from Mie scattering. Other interactions with the incident particle can cause Raman and Compton scattering too. None of these need multiple particles.

        Earth’s atmosphere is also the reason why we see some stars flickering. The light of the star is constant, but our atmosphere creates diffusion, so some of the photons don’t reach our retinas. Technically, if you and your next door neighbor look at the same star, it’s flickering for both of you, but the flickering is not synchronous since position of observation matters.

          Yes. pV=nRT. If you keep n constant (same number of particles), drop the volume (V) and crank the pressure (p) proportionally, then the only variable left is T, which would have to rise. This is called adiabatic compression. What’s being described is an engine piston the size of the atmosphere and a compression ratio thousands of times higher than what we can normally make.

    I feel like it’s quite the strawman or misunderstanding when people ask for material proof of God. Can you prove math using empirical verification? No. because math is not something you can empirically verify as it does not exist materially.

      You can empirically prove math like you’d empirically prove other things - make predictions based on math and test these predictions. But it seems like you are expecting these proofs to be like mathematical proofs - uncompromising logic that leaves no room for getting false positives by chance. They won’t. They’ll be like all other empirical proofs - “mere” scientific theories that must forever live with the possibility - however improbable - that the universe somehow aligned to make all the predictions come true even though the hypothesis they were derived from is wrong.

      But this is not a property of the math we were trying to prove. This is just the nature of the empirical proofs. Implying, based on that, that math is less verifiable than all the physical observable things (like frozen oxygen) is ridiculous - the proofs for these things suffer from the exact same problem!

        The (poorly) argued point they are trying to make is the distinction between the empirically identified congruences between the math and the internally consistent tautological truth of the math itself.

        The reason I bring this up is your point about math modeling empirical evidence is an important distinction. Where their argument truly breaks down is the idea that all internally consistent tautologies are of equal value to us as humans. This is obviously false.

        And frankly, their other argument about this showing that true things exist without empirical proof is offensively stupid since we already have much better proofs demonstrating that true things exist without proof.

          we already have much better proofs demonstrating that true things exist without proof.

          Isn’t this a contradiction? These “much better proofs” are proofs - which means that these “true things” are not “without proof”.

          Also, I’m not sure what “things” you have in mind here, but I’m fairly certain they don’t “exist” in the same sense math does. Math exists in the same hard sciences do - any mathematical discovery, just like discoveries, is a rule that reality follows. Of course, I’m not implying that the mere formulation of this rule by human researchers is what gives it the power to govern the universe - we are just discovering laws that were already there.

          Other things that are derived from human thought (rather than empirical evidence) and do not fall under the wide umbrella of math, don’t exist the same sense. You may claim that justice exists, but it’d be silly to expect the universe to obey to principles of justice. It won’t be silly to expect it to obey to mathematical principles.

          Had @[email protected] brought something like justice as their example, we could have talked about the meaning of existence and what does it mean for God to exist in the same way justice exists. But they didn’t - and I really try to avoid formulating other people’s claims for them, because even if I get it right they may still find (or invent) some nuance I got slightly wrong, leverage that to claim I understand nothing about their philosophy, and derail the entire conversation to revolve around that.

          They didn’t mention these other “true things” that “exist without empirical proof”. They mentioned math. And math can be proven empirically using material evidence and the scientific method (of course, you need to make sure you are not trying to prove the parts of math that are crucial for the scientific method itself, because then your proof will be circular…)

            Godels proof is quite clear. There are infinitely many assertions that are true but have no proof. Those assertions can be mapped to extant things. This is not an area that requires deliberation. If you are unfamiliar with the incompleteness theorum we can discuss it more. The fantastically great thing about this work is that it was the pursuit of a “complete” purely philosophical logic derivation of mathematical principles (the continuation of the work by Bertrand in the Principia Mathematica).

            The thing here is we are arguing two different points… You are arguing that empirical evidence can demonstrate the usefulness of models to explain more empirical evidence… Which is true. I am arguing that philosophy builds models. You aren’t wrong(except that part about not trying to prove the parts that are crucial for the scientific method… You are just wrong about that) and I am not wrong. We are arguing different things.

            Math is based on logic, we can’t prove it scientifically because it’s not something which is empirically verifiable but provable through deduction. If we are happy with logic to prove math what is wrong with logical arguments for God? I’m not against science or needing to prove your theories. I’m only against the notion that if you don’t have empirical proof for God then God doesn’t exist.

            Right, so in Math we have axioms and we build upon those axioms and construct theorems which are deductively true. They are not true in the same way a scientific theory is. My point is, not everything that can be true needs empirical verification. Math is one example.

              While what you say is true, tautological arguments are not useful in and of themselves. Internally consistent mathematics is not a useful construct unless we can empirically discover structures that those mathematical systems model. Einsteins theory of relativity is not impressive without the empirical discovery that the it is/was a better model than the existing Newtonian models that proceeded it.

              To argue that internally consistent tautologies are true and are of equivalent usefulness is a bad faith argument that inappropriately equates two logical constructs.
