> Again I think you are confused. Assuming random distribution, 'We Are Coming' is just as likely as any other similarly long structure to form.

You are confused. How could we be back to square one? We've discussed it before. I'm not arguing that "WE ARE COMING" is more likely than, for example, "WE RAE COMING". Of course, they are as likely.

Suppose you have a machine that generates 15-char strings. Yes, "INTERCHANGEABLE" is as likely as "YSVQEPQVIGXOQSR" to come out—but that’s not the point. My point is that the probability of getting a proper English word is very unlikely. Most of the time, you'll get gibberish strings.

Also, I didn't say the sentence to be encoded in morse code. Instead, the galaxies form the literal shape of "W", "E", and so on. I hope you can see that in this case, it's borderline impossible to happen.

Sure, but given a large enough sample both will likely exist. So the fact that one happens to be english should not surprise anyone nor does it suggest meaning.

I used morse as its easy to reason about. There's no reason to think shapes are impossible - you just have to define what makes a shape and then look for patterns that match.

Humans have been finding patterns in clouds, stars and even toast since time immemorial.

You just don't understand probability, possibility and potential very well. Yes, you can get hung up where you are and we can argue semantics - the fact is that if I throw 1000 dice and get 1000 "1"s that is not the same as my being able to theoretically do that an equal % chance each throw.

The ring may be possible but, so far, it's the only example so despite being a potential random outcome of randomness, the sheer singularity of its existence proves it's incredibly low likelihood of occurrence - perhaps such a low % chance of actually occurring that it may be easier to believe that the ring had help in its formation, whatever that may be.

I'm not going to deny obvious things just bc they challenge my worldview - especially if I have to defend my viewpoint semantically

This applies to every event with nonzero probabilities. What's your point?

> Humans have been finding patterns in clouds, stars and even toast since time immemorial.

I knew this—humans love finding patterns. But our discussion is not about that. It's about the very basic thing in probabilities, which is some event is not as likely to happen as others. This is so trivially true.

The probability of getting a proper English word from a random string generator is much less likely than the probability of not getting it. Thus, getting a proper English word should be surprising. It is as surprising as getting any string from a set of gibberish strings with the same cardinality of English vocabularies.

> So the fact that one happens to be english should not surprise anyone

What should surprise you, then? I'm surprised that we need to talk about this very basic thing three times.

[unusualmonkey]

> But our discussion is not about that. It's about the very basic thing in probabilities, which is some event is not as likely to happen as others. This is so trivially true.

Except that's not a given.

Any equally long random string is as likely as any other equally long random string.

Different length sets of random strings may differ in probability.

Finding what might appear to be meaningful structures in large data sets, e.g. shapes in 2T galaxies, doesn't inherently suggest anymore than chance.

I agree to almost all your points from the previous four comments, and I think so do you to my comments (because you didn't argue against my statements). We differs only on what to discuss.

Before I give up on this discussion that's always back to square one, maybe this question (that I've similarly asked) will help set a baseline:

What are a few examples of probablistic events that should surprise you?

[Retric]

When the entire class of things are unlikely given the number of observations. The odds that I personally may win the Jackpot are low but the odds that someone at sometime wins is very high. So me winning would surprise me but someone winning wouldn’t. Applying that rule to research and a lot of people are looking for something interesting in many domains not just this particular one.

Similarly finding any shape in a random set of points is much more likely than the odds of any one shape.

So you need to adjust for both things people are looked for correlations and the entire class of things that would notice not just the odds of what you happened to see. A random process you run spitting out a famous quote would be low, but you would also be surprised Pi is 3,14 or Pi is 3.14 etc etc.

Thus someone else hitting a random process and getting “To be or knot to be” is now looking at the odds that anyone anywhere would get something that’s close to something memorable which should actually be quite high.

> Similarly finding any shape in a random set of points is much more likely than the odds of any one shape.

Obviously. But that’s not the point (no pun intended). My point is that most of the "shapes" would be just an unstructured shape—if you can even call it a shape. "Familiar" shapes will be much much unlikely to form that "uncommon" shapes. (Hopefully this is obvious because the number of familiar shapes are much much fewer than uncommon shapes.)

Let me use another example to help you understand the point. Suppose a monkey is given a typewriter and a sheet.

Is the probability of getting The Declaration of Independence is as likely as the probability of getting one particular gibberish sequence of characters? Yes.

Should we surprise if the monkey types any proper one-page English essay? Yes.

In case it's not obvious, that's because the number of possible ways to write a proper one-page English essay, albeit humongous, is nothing compared to the number of possible ways to arrange characters in one page. In other words, it's very very very unlikely to happen.

[Retric]

> Should we surprise if the monkey types any proper one-page English essay? Yes.

You can’t exclude non English languages being you would still be surprised if it was in Spanish etc. If your test is if anything surprising happens, then you must consider every possibility that you would find surprising.

Also, this isn’t some mathematically perfect shape it’s a points in a clump that we’re classifying as a shape.

As such a monkey typing someone vaguely like a proper one-page essay in any language or encoding would still be surprising, but is probably 10^1,000 or so times more likely than any specific sequence.

[beltsazar]

> You can’t exclude non English languages being you would still be surprised if it was in Spanish etc.

I'm not saying that the only surprising result is an English esssay. But sure, let's add all languages in the world. Getting a proper one-page essay is still surprising, because the absurd number of ways to arrange characters in one page. It's much much much larger than even the number of particles in the universe.

> but is probably 10^1,000 or so times more likely than any specific sequence.

Obviously. Your point? If the probability of an event is so low, it doesn't really matter if it's 1 in 10^1000 or 1^1000000. If that event happens, it is surprising.

Anyway, I'm not arguing that the galaxy ring is a rare occurrence, hence surprising. I don't know even an approximate probability of it to happen.

I'm arguing against those who shrug and say "Well, it's random, so even a complex structure can form." Not necessarily. It all depends on the processes behind it.

Case in point: Darwin's evolution. The only reason that it's plausible that random processes can transform basic living organisms into complex ones like mammals is DNA replication.

Without DNA replication, random mutations between generations would be independent, just like random key presses by a monkey. You need to start over every time. This makes it essentially impossible to form complex organisms over time, considering how long DNA of complex organisms is.
