I was visiting Chabot Space Center in Oakland several years ago and saw a large poster on a wall which had thousands and thousands of star-like dots filling the entire sky.

Except, they were not stars, they were galaxies. A poster of a small portion of the sky full of thousands and thousands of galaxies, each looking like a dot, as small as a star looks in the night sky, and each of those galaxies has billions of stars...

Something snapped in my brain that day and I went on from being somewhat religious/agnostic to a full blown atheist.

There is a palpable difference between the universe described by many religions and the universe described by science. The former is all built from concepts rooted in human society such as father, son, judgment, commandment, obedience, sacrifice, punishment etc. The latter is built from eerie ideas such as force field, wavefunction, observable, reference frame, superposition etc. The former feels small, ordinary, familiar and manmade. The latter feels like we're fumbling for words to describe something that fundamentally transcends ordinary human experience.

BTW: The numbers involved in each description are also telling. Those used by religions are often small and comfortable for a human mind, e.g. ten commandments, seven days of creation. Even the supposed large numbers such as 144,000 never come close to what you need to describe nature such as the number of stars in our galaxy (around 10^11) or the number of atoms in a human body (order of 10^27). See physics constants for even better examples. Also, religions often describe reality using numbers that look suspiciously memorable in decimal notation. OTOH, nature never gives us round decimal-friendly numbers for constants. I think this also makes religion feel manmade and science authentic.

The word "religion" has a lot of baggage associated with it where it seems to invoke a stereotypical undereducated westerner who interprets ancient spiritual texts literally. There's a lot more than just that. Ancient Buddhist cosmology frequently uses metaphors to describe aeons, such as grinding mountains to dust by brushing it with silk cloth once per century, etc. They do the same with countable objects to describe the numbers of worlds and so forth.

I have the opposite experience you described. Contemplating the infinitude of reality draws me toward religion via logic. Through contemplation it seems to follow that there's something important happening with meaning beyond our comprehension.

Perhaps GP and GGP were "stereotypical westerners who interpreted ancient spiritual texts literally". I for sure was, having been brought up in particularly scripture-obsessed denomination of Christianity. But I'd argue that view holds true for all Abrahamic religions, which comprise the majority of active faiths on Earth. Religions based on the Bible tend to be half faiths, half community management handbooks. Despite promises of various forms of life everlasting, they're very much focused on micromanaging the profane, the mundane.

This reminds me of my favorite Richard Feynman quote:

“Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one - million - year - old light. A vast pattern - of which I am a part... What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?”

First definition I find of religion: "A set of beliefs concerning the cause, nature, and purpose of the universe, especially when considered as the creation of a superhuman agency or agencies, usually involving devotional and ritual observances, and often containing a moral code governing the conduct of human affairs."

Almost every atheist will reject religion, given what religion typically is and which is captured pretty well in the definition above.

Nothing, but I suspect your concept of "religion" is not the same as the parent's. Some people think of religion is a valuable tool humans invented to help them govern their lives . To others, religion is a doctrine that teaches ostensibly facts about the nature of the universe. Typically these facts lead to conclusions such as "humans SHOULD do x, MUST NOT do y", etc.

Two completely different concepts, one word. So it's a bit confusing. But for someone discussing the second type of religion, saying it's "man-made" is definitely a knockout punch.

gag, pet peeve of mine. Religion is, to quote TeMPOraL "Religions based on the Bible tend to be half faiths, half community management handbooks."

you can generalize that statement very far; religion is one of the key "technologies" which allows communities to scale past 5K people. Think "city".

Thus religion has a very different purpose than physics. It is about psychological health on a community and individual level.

The stories of physics, on the other hand, "eerie ideas such as force field, wavefunction, observable,..." don't really tell you much about how to handle things when your neighbor's barking dog is frustrating you.

(insert snarky comment about engineering a force field to solve the problem)

Even assuming that the bible is the literal word of deity, it is inconsistent to believe that the creation stories of genesis are descriptions of actual physical processes. because that is not why deity put those stories there. because deity was talking using a language which is 1.5-3K years old (let's agree to not argue dates, I'll accept the date you prefer), and words like "world" and "universe" meant something very very different back then than they do today. So if it is deity's literal word, then it must literally mean what it meant in the context of that earlier culture.

Re:100k Stars by yumraj on Wednesday October 07, 2020 @02:55AM (#24705918)
It's not a direct relationship, but IMHO an indirect one.

Personally for me it is basically like this, that the Universe is so infinitely huge, somehow just calling it huge doesn't do it justice, wherein the concept of God or Gods as is defined by most Earth religions seems too tiny to describe an entity or a race of entities that could be the real God or Gods.

Moreover, even if the above mentioned entity or race of entities does exist, which created the Universe, I'm so infinitesimally tiny that they don't care about me, and certainly don't care about whether or not I pray to them.

In other words, the human concept of God or Gods is just one level above the humans. And, then if you add the fact that this one-level-above is also just a matter of faith and there is no evidence even of that, then the whole thing crumbles.

In other words, whether or not there is a God or Gods, has no bearing on me and my life and me and my life's decisions are not going to be bound by that.

Whether that is atheism, or being agnostic, or something else can be left undefined. It's more like, I don't care. It is simply that my life's decisions are not going to be in any way influenced by whether or not God or Gods exist, whatever the right word for that is.

BTW, the Hindu cosmology [0] does delve into such philosophical things, and perhaps my Hindu upbringing has something to do with my beliefs wherein asking such questions and pondering over them is allowed.

It depends on what theism is to you. For many people [0] believe in God is tightly intertwined with the idea that this supernatural being has strong opinions about how life on Earth is to function. And it's hard to believe that when you look at the scale of the universe and how small our lives are relative to it all.

It's possibly to believe in God and think that God is too busy with the cosmos to be concerned with our tiny lives. But it isn't a very "useful" belief, in the sense that it's a belief with no practical implication.

A counterpoint is this idea:

Imagine how much awe you feel on realising that the awesome scale of the universe is nothing to the even awesomer scale of God who can give personal attention to everyone's tiny lives throughout the entire universe!

It would imply that God has limitations, which goes against the usual view (at least in abrahamic religions) of god being unlimited by definition. It would also invite the question of where those limitations come from. If that's not a practical enough implication, there would also be: dont rely on God for personal attention.

Re:100k Stars by names_are_hard on Wednesday October 07, 2020 @07:55AM (#24707292)
I think we're in agreement. What I meant by no practical implication was that if I'm an atheist and then I learn that there is in fact a God, but he's either too busy, limited, or otherwise uninterested in my life, then I can shrug off that information with no negative consequences. It doesn't matter to me if there's no God or if there's an uninvolved God, except as an academic question (ie no practical implication).

But if I'm an atheist and I learn that there's a God that cares about me or my behavior then I will likely have to change my lifestyle. Maybe I'll have to start praying, or giving charity, or stop stealing, or start dancing around a fire now and then so that the rain comes, or marry in a certain way, etc.

It's no surprise to me that the popular versions of God-belief out there describe a God that's very involved in Earthly affairs. Because otherwise, what's the point?

Re:100k Stars by frosted-flakes on Wednesday October 07, 2020 @09:16AM (#24707832)

Re:100k Stars by names_are_hard on Wednesday October 07, 2020 @02:49PM (#24711332)
Exactly. To my knowledge most religions teach that what comes after life depends, at least in part, in what we do during our lives. In other words, God is concerned with us and how we live on Earth. Which is remarkable, given how large the universe is and how apparently insignificant we are.
Re:100k Stars by frosted-flakes on Wednesday October 07, 2020 @07:55PM (#24714209)

Re:100k Stars by jiggawatts on Wednesday October 07, 2020 @07:12AM (#24707078)
I'll try to answer your comment more directly. The other responses are good, but they're not exactly responding to your comment about the parent commenter's change from agnosticism to atheism upon learning the scale of the universe.

I've had a vaguely similar experience, but over a longer period, not a single "moment", and not entirely to do with the physical sciences.

They way I look at it is this: To ants, we are gods. We can provide an unimaginable bounty to them by simply dropping the remains of a sandwich. We can destroy their entire world with callous indifference. A step in the wrong place is all it takes to crush an anthill.

But do we care about an individual ant's good behaviour? No. Not in the slightest. I don't meet out punishment on one particular worker ant because it failed to respect the queen, or move enough seeds one day.

Simply put, we are so far removed from ants, so far above them, so much greater, that there can be no meaningful interaction of this type. The UN general assembly does not give a flying fuck about the misdeeds of a particular ant in some particular ant-mound in some particular forest, in some national park, in some country far away. Conversely, an ant can have no concept of the latest UN resolution's effects on international tourism and its side-effects, such as the likelihood of an increased number of dropped sandwiches in national parks. There is no though that an ant can possibly have that can encompass even a fraction of such concepts. They're simply too abstract, too advanced for such tiny brains.

Any God that could possibly have made a Universe as vast and complex as ours would be similarly far removed from us. We would be ants to such a God. Personal, individual communication of any type would be hopeless. A "relationship", as Christians like to say, would be absurd in the extreme. Ants don't have relationships with senators, or kings, or generals. It's simply unthinkable.

Science could study such a God, if it existed, but it wouldn't be entirely clear if it would be possible to actually gain a truly meaningful understanding. A superficial, surface knowledge, perhaps, but that is all. Prayer would certainly be an utter waste of time. Holy books could not have possibly be written or inspired by such a God. Rituals would be meaningless. Rites and celebrations would also be embarrassingly pointless.

Re:100k Stars by furyofantares on Wednesday October 07, 2020 @01:41AM (#24705614)
It's certainly possible to have a religion that accounts for the grandeur of the universe, and there have certainly been many religious folks whose religious experience is heightened by their understanding of the cosmos, but I'd guess those folks have put a fair bit of their own efforts into such belief because IME the common teachings of the major religions imply that the actions of the humans that live in a tiny slice of history in a tiny piece of the cosmos are of major significance. I would argue that perceiving some of the grandeur of the universe may make it difficult for the most common teachings to really resonate without significant modification.

Also, for folks who are drawn to religion primarily due to "spiritual" experiences they've had with the religion -- where they experience a loss of self, a one-ness and connected-ness with others, and a distinct sense of clarity -- it may be that having a very similar experience in a non-religious context may lead to new beliefs about what that experience is or means.

There are two basic reasons to give up on religion. Reason One: It's obviously silly. Reason Two: Some personal epiphany.

For a lot of people, Reason One just isn't enough. They need a story to go along with their revelation. They need to look at a picture of a galaxy, or watch their religious grandmother die slowly, or read about pedophilic priests, or whatever.

Alan Watts talks about this idea in The Wisdom of Insecurity. I don't have the book to hand so this is the closest quote I could find:

“The discovery of this reality is hindered rather than helped by belief, whether one believes in God or believes in atheism. We must here make a clear distinction between belief and faith, because, in general practice, belief has come to mean a state of mind which is almost the opposite of faith. Belief, as I use the word here, is the insistence that the truth is what one would “lief” or wish it to be. The believer will open his mind to the truth on condition that it fits in with his preconceived ideas and wishes. Faith, on the other hand, is an unreserved opening of the mind to the truth, whatever it may turn out to be. Faith has no preconceptions; it is a plunge into the unknown. Belief clings, but faith lets go. In this sense of the word, faith is the essential virtue of science, and likewise of any religion that is not self-deception.”

Interestingly, I know many scientists who take a general theistic worldview (might I say universeview?) despite (or, I think, because of) this vast universe.

Re:100k Stars by nkrisc on Wednesday October 07, 2020 @11:37AM (#24709310)
I think it's because the more we learn about the universe in which we exist, the more and more apparent it becomes that we are not a special part of it, that there is so much more to it than tiny slice of space and time we happen to occupy. The universe existed long before us, and it will continue long after us. We are inconsequential. This is all pretty contrary to what most religions tell us.

Personally I have no reason to trust or believe what clergy say (they're as human as the rest of us and make lots of unverifiable claims), so all I have to go one is what we collectively discover about our universe.

A black hole containing all matter in the universe wouldn't be much denser than the current average density of the universe. Spacetime expanding sorta helps keep things from blowing apart.

It's an interesting factoid that blackhole mass isn't related to their volume but their surface area, so by adding mass they grow a lot faster than you'd expect and density goes down fast. Larger black holes are barely denser than water.

I was surprised by this and I don't think your sentence is entirely clear, but the ending figure seems to check out. I think it's more clear to say "the radius of a black hole increases sub-linearly with its mass" (specifically, the square root of mass).

Sagittarius A*, the closest black hole, is 4.1 million solar masses, so its Schwarzchild radius is 12.1 million km, so its density is 0.25 kg/m^3, which is about 1/5 as dense as air at sea level--much less than water.

A black hole made from Jupiter would have a Schwarzchild radius of 2.8 meters, so its density would be... denser than a neutron star.

Re:100k Stars by phs318u on Wednesday October 07, 2020 @07:16AM (#24707101)
Hang on, it’s been a long time since I studied physics at uni in the mid 80s, but isn’t the Schwarzchild radius just the boundary which marks the point within which even light cannot escape gravity? A black hole is a singularity, a point (if non-rotating) of infinite density. I didn’t think the mass of the back hole was evenly distributed within the Schwarzchild boundary (which is a mathematical boundary, not a physical boundary such as the surface of a body). Or have I missed something?
Re:100k Stars by zaarn on Wednesday October 07, 2020 @08:18AM (#24707433)
Depends on how you look at it.

If you look into holographic theory (which I prefer personally) then the entire mass of a black hole is represented as information on the surface of the black hole, explaining the relation between mass and surface not mass and volume. This solves some problems with the information theorem (no information can be lost) by presenting all information contained within a black hole on it's surface where it can be read, atleast theoretically. (Here information and mass would be considered equivalent)

To some extend, it still holds true if you just consider the mass of a black hole to be it's singularity and it's volume the volume that fills the event horizon.

edit: Also consider; if you placed an equivalent amount of mass in space that occupies less volume than the event horizon would, it would automatically be a black hole (and note; the schwarzschild radius is not necessarily the event horizon, the event horizon can be tighter if the black hole rotates)

The relevant figure is that the radius grows faster than mass^(1/3). What it does, because it grows with mass^(1/2).

If it grew more than linearly with mass, we wold see the same reducing density, just faster.

For extra mind blowing, do compare the Schwarzschild mass of the observable universe and its radius.

So I quickly did a back-of-envelope calculation using [0] for source of mass and diameter of the universe.

Then I used the formula given in [1]: r = (2 G M) / (c^2).

    You have: (2 * G * 1.5 * 10^56 grams ) / (c^2)
    You want: lightyears
            * 2.3548373e+10
So about 23,548,373,000 ly of SR, while the radius of the observable universe is given as ~46,500,000,000 ly. So the ordinary-matter ratio is about half the density of a black hole. Not quite there, but still _much_ closer than I would have thought!

If we account for not just ordinary matter but dark matter (a ratio of 4.9% to 26.8%) the picture is different:

    You have: (2 * G * (1.5 * 10^56 grams + (1.5/4.9*26.8) * 10^56 grams) ) / (c^2)
    You want: lightyears
            * 1.5234355e+11
So the SR then would be about 5 times larger. But I have no idea whether dark matter would count towards the black hole mass and SR, and I don't know if anyone does.

Yes, dark matter has mass, this is its defining characteristic: it seems to be a detectable mass, just doesn't interact electromagnetically.

In any case, it's important to note the Schwarzchild model is a spherically symmetrical ball. Mass in our Universe seems more or less uniformly dispersed (with some anisotropy). Without a center for mass to collapse, I suspect the black hole dynamics don't apply.

For me it worked in the opposite direction, the more I learned how all the World elements are connected, how laws of Physics made live possible, how those laws are connected with the logical rules that our World has to obey (like causality) the more I become convinced that all this had to be designed.

That's cool. I hope you can find and be satisfied with the materialistic explanation of the sheer awe you are feeling when you think about all these galaxies.

Jokes aside, atheism is a religion (as in fundamentalist belief system), and not a nice one either. Being agnostic probably keeps your mind more flexible [citation needed].

Re:100k Stars by kruasan on Wednesday October 07, 2020 @01:52AM (#24705646)
That's naive. Why would I let it go?

Firstly, contrary to Benatar, our lives are not "meaningless", even from a cosmic perspective. Our personal problems, concerns, relationships, and feelings are in no way less significant merely in the virtue of the size of the (multi)verse. Your feeling of pain is still pain, whether the universe contains billions of galaxies, or is just 10 light-years across. Same with joy, same with health, everything.

Secondly, our lives are certainly not inconsequential in the grand scheme of things. The whole future of the Sun depends on whether humanity's descendants exist long enough to develop the technology to stop it from going nova and gather its energy. If Earth is indeed the only planet in the observable universe to contain life, then our lives are of tremendous significance. Either we live and hopefully, build grand Kardashev IV-utopia among the stars changing the universe completely, or we go extinct.

Re:100k Stars by nostromo on Wednesday October 07, 2020 @02:09AM (#24705709)
I mean... the second law of thermodynamics says we’ll go extinct no matter what we do eventually.

There’s no denying that the heat death of the universe is a pretty depressing idea.

Re:100k Stars by tutfbhuf on Wednesday October 07, 2020 @02:20AM (#24705758)
> stop it from going nova

Somehow preventing our sun to swell into a red giant is also only a short term and meaningless problem in the grand scheme of things. You would have to prevent the heat death of the universe if you want human mankind to exist forever or accept that things will eventually come to an end.

Even if we assume we could somehow do this, I would recommend you to watch some Star Trek episodes with Q. Living forever can be even more depressing than to live one finite life.
Re:100k Stars by TeMPOraL on Wednesday October 07, 2020 @03:00AM (#24705937)
And I'd wary against generalizing from fictional evidence. As much as I love Star Trek, it has one hell of a anti-life-extension, anti-transhumanism bent. Perhaps because it's a story about humans becoming a better people, and for it to be directly relatable, it has to involve humans like us - unmodded, whether by genetics or technology.
Re:100k Stars by tutfbhuf on Wednesday October 07, 2020 @04:06AM (#24706225)
I mean you can use your own brain and think about the idea of living forever and the consequences it would have. The more I think about it, the more it becomes a depressing idea at least for me.
Re:100k Stars by TeMPOraL on Wednesday October 07, 2020 @04:41AM (#24706371)
I've done that a lot, and I find it an optimistic idea. Sure, we'd need to refactor some things in society to root out the hidden structural dependencies on life expectancy being double-digit years, but other than that? I see mostly upsides.

(And in terms of boredom, because I'm guessing that's what you allude to by invoking Q: you can always decide to end your existence after you get bored with eternal life.)

Re:100k Stars by tutfbhuf on Wednesday October 07, 2020 @03:20PM (#24711658)
It's about meaninglessness. Maybe it's just me, but things (including life) that are finite are valuable and special for me. Also in terms of Lord of the Rings I would rather be a human or hobbit instead of an elf. But I respect elves and get your point, it's just not for me.
Re:100k Stars by TeMPOraL on Wednesday October 07, 2020 @08:00PM (#24714244)
Eternity is an overwhelming concept. It's easier to tackle it through mathematical induction.

Can you imagine a day in which you feel so fulfilled, so bored, that you say to yourself, "it's enough"; a day in which you wouldn't be interested in what tomorrow will bring? I can't. Hence, by induction, I'd prefer immortality.

I'm probably not going to change your mind, just sharing the elvish perspective.

Re:100k Stars by rlonn on Wednesday October 07, 2020 @02:29AM (#24705794)
Naive you are, if you believe life favours those who aren't naive

And, to nitpick: the sun will never go nova.

Totally agree. I bought a telescope as a hobby, but really, it also acts as a mental health booster. We are just specks of dust in an infinite galactic soup. I didn't expect this side effect when I bought it!
Re:100k Stars by dheera on Tuesday October 06, 2020 @10:58PM (#24704905)
Telescopes are one thing, but there is an impressive amount of stuff out there in "plain sight" that is invisible because it is too far at the edge of the visible spectrum, or too dim.

I've been recently doing a project to photograph a lot of these massive interstellar objects in the perspective of landscapes to show how visually big they are. For example, here's a picture I took of the Rosette Nebula rising over Mt. Shasta. The nebula is visually bigger than a full moon, you just can't see it easily with the naked eye: https://www.instagram.com/p/CCO0CmnnVkA/

I don't know I've always found this line of thinking bullshit.

First the only thing you will eperience is your own life. The only things that should "matter" by definition is the thing you can have influence on and will be important for your life. Why something you can't have influence on (space) should matter in how I make decisions ?

I agree with the general, bigger line to not get too much stress about random stuff, but in that case I prefer the line of thinking that short term problem are usually meaning less compared to the duration of of your life, than trying to justify it by the fact that "a universe exists".

Sorry for the use of "bullshit" if you're the kind to be offended by that

Re:100k Stars by neuronic on Wednesday October 07, 2020 @04:09AM (#24706235)
Because the universe around us is unreachable, for a long time coming. It simply does not matter to our daily life that we are insignificant. We can observe, explore and expand knowledge. But never touch the surface of any other planet or feel the warmth of another star. Your neighbor matters more to your life than the Andromeda galaxy.

Not even the closest star changes or affects life on Earth in time scales relevant to us. For all intents and purposes we are an isolated microcosmos, save maybe some astronomic catastrophes unlikely to happen within humanity's span of existence (which isn't even a single million years yet).
