Still untrue, despite being repeated. Then you have been really bad at framing this question Is the point you want to make is that dissimilar conditions do not give identical results? Or is it dissimilar processes? Or is it that results can never be replicated exactly? I would argue that none of these are necessarily true, or that this matters, but we need a decently-defined premise to discuss, and you haven't provided one.

Nothing about this has been about "dissimilar natural process producing something the same" You claimed that "Nothing in nature is observered (sic) to happen again or twice ...have a look yourselves! " You said nothing about processes or results. But you keep returning to a particular, narrowly-defined example that doesn't happen, where nobody is surprised that it doesn't happen, or rarely happens. This is known as moving the goalposts, and it's a dishonest debating tactic. ... I remember someone I knew long ago that argued that evolution is false because a dog never gave birth to a cat. He thought that was a persuasive argument, when in fact it just showed how little he understood about evolution. I see a similar phenomenon happening here.

A similar path I had was a set of Time-Life books on science. We had a Grolier encyclopedia set, which was a prize contestants (my mom) got for appearing on Jeopardy!

I haven't seen you use scientific fact and reasoning yet in this thread Again you have made a vague prediction. If the pattern holds, you will then move the goalposts when this is shown to be false, and you will apply a much narrower set of criteria to try and cover your error. A sun doesn't have to be the same as ours for it to be a sun. Again with the intellectually dishonest reasoning. Life would be biological, even if it were different that what was formed on earth.

Interesting, as you have not defined life at all, and this suggests you would artificially narrow the definition to be DNA-based. You didn't specify that it had to be the same water until after your argument was rebutted. I'm not aware that worms evolved into humans. Certainly not any extant species of worm. You can't possibly know if it was fast or not.

This is getting tiresome. Repetition is not proof. "Nothing" has to include all cases, and the only examples you can show are for very specific cases. You can't extrapolate from that to a general truth of the statement. Not reputable? I'm not required to, in order to disprove your statement. You can't limit responses to a specific avenue of proof. It's an intellectually dishonest requirement. We can't be sure life on another planet would be based on DNA. There's no requirement for the results to be identical, other than your artificial narrowing of the answer you will accept.

"Because Andrew William Henderson said so" is not a physics principle. Repetition does not make something true. Is anyone predicting an exact outcome of a future event here? I'm not understanding your point. Asserted without evidence. (I'm sensing a pattern) Abiogenesis might actually be relatively easy under the conditions of the the early earth. It might be that it only took a thousand years after the right conditions were met for it to occur. That's fast using the age of the earth as a scale. We just don't know. And if we don't know, you can't make a valid assertion one way or the other.

Hence the "dark" moniker There's no reason to think there is, either, which is a stronger statement. The BB extrapolates back to a singularity, but at all times past that (i.e. at all times we have physics that we can discuss) there is dark energy and no singularity. "All sides around the universe" has no meaning.

And this depends on what that "thing" is. If that "thing" is some kind of eye is developed, then that "thing" has happened multiple times. Your examples have focused this down to a narrow instance of something so that the statement is true, but it's only true for those narrowly-defined instances, and you are improperly extrapolating those examples. Suns (i.e. stars) happen all the time. Suns similar to ours happen pretty often. There's no reason to think a star has to be exactly like our sun to support life. Abiogenesis in no way "bypasses" entropy, and I don't see how the Lorenz effect applies. (and you have made the case for neither; just doing a Gish gallop isn't going to get you anywhere)

Perhaps there is some bit of relevance: the differences in the gold between two locations is dependent on stuff that isn't gold. The gold itself (the atoms of a given isotope) are identical I'm not even sure you could rule out life emerging more than once on earth. Abiogenesis happens, and then some cataclysm wipes it out before it can spread and take hold, and a thousand years later abiogenesis happens again. This could potentially have happened many times. None of the evidence would have survived.

I provided three links that shows this to be in error. Have you provided any examples of it being "hidden"? Usually it's derived with few constraints to it, and no initial conditions. e.g. start with a = dv/dt, which is the definition of acceleration (always true) Add in the condition that acceleration is constant, and integrate the equation and you get v = v0 +at Apply the definition of velocity, v = dx/dt Integrate again and you get s = v0t + 1/2 at2 The initial velocity is there (as it is in so many textbooks, if you'd only bother to look), and the only restriction is that you must have a constant acceleration Only if you forget to include it, but that's on you

To a very limited extent, yes. It's more difficult to confine them because you don't have an overall neutral configuration as you have in a plasma, so the electrostatic repulsion will quickly get very large as you add electrons.

No, it's information

No. Unless you can hand me a cup of information.

Hogan's Heroes is (mostly) 60s

We're not talking about Fibonacci. In any event, it shows the growth is related to φn which is indeed exponential. If you click on your link and then the "exponential rate" link and look at the graph, it shows a linear function, as well as 2n and x3 You can see that they are not the same growth.

2±n is exponential x±2 is not

Black holes attract matter in violation of the inverse-square law (where Newtonian physics would apply)? Citations please.

Sure they are. And as such, fermions follow Fermi-Dirac statistics. Bosons follow Bose-Einstein statistics. Both of which require identical particles. This is the opposite of what was discussed, which was: same process, different outcomes. You are asking for identical outcomes. If I drop two masses off the tower of Pisa, they will both undergo the same gravitational acceleration, even as other forces may be present to give small differences in their velocities at any point. You seem to be conveniently ignoring the fact that your original framing did not ask for identical results. You said nothing happens again or twice. Gold being formed in California and again in Queensland (or vice-versa) is something that happened. You are now moving the goalposts, something that has also happened many times, particularly in arguments like this.

No, it's not. Convergent evolution wouldn't result in identical species. But you didn't say anything about the same species emerging. The claim that "Nothing in nature is observered (sic) to happen again or twice ...have a look yourselves! " is not the same as saying some species would emerge twice. The former is very vague* and demonstrably false, while the latter is true and unsurprising, given what we know of evolution. * "nothing" covers a pretty wide range of items and phenomena. All of them, in fact. So as exchemist notes, processes repeat all the time, even if the outcomes differ.

No, it's the galaxies not bound to each other that will continue to recede from each other. The stars in these galaxies will burn out and eventually new stars will not be able to form. Redshift is caused by motion away. If the motion is towards each other, there will be a blueshift. There's also a redfshift as light climbs out of a gravity well.

Octopus eyes and human eyes are "wired" differently (humans have a blind spot); they did not arise from a common ancestor. Eyesight is something that developed multiple times in the course of evolution. It's not the only trait to have done so.
