Thank you for all the information. Keep it coming, please. I will have what to work on after I finish the 500 pages book I'm working through now (that's on QFT).

Here is an interesting plausible possibility that I didn't see mentioned yet. Given that a physically accessible part of the Universe is finite, there can be only a finite number of intelligent civilizations in it. Among this finite number of civilizations there is one which is the most scientifically and technologically advanced. Which one is it? It is plausible that we are the one.

I see an important difference between this example of a low probability event and the event of intelligent aliens' invasion: we know with certainty that there are plenty of flying rocks in the Solar System.

Historically, after Newtonian formulation of mechanics, alternative formulations were developed, i.e., Lagrangian and Hamiltonian. In QM, after wave mechanics, matrix mechanics was developed. In QFT, there are S-matrix and path integral formulations. Which alternative formulations of GR are known today? PS. I think, in SR the parallel examples are Einstein and Minkowski formulations.

Backup like computer files? I don't think this analogy is correct. You take a backup and put it aside, hoping that you will not need it. This is nothing like reproduction. In reproduction, the previous generation is replaced by the next.

What is wrong with looking down at your feet? Or anywhere else than stars? What does it have to do with work? I wouldn't recommend looking up at the stars while hitting a nail with a hammer. And regarding the last part. Life can be empty with or without work. It also can be full with or without it. Never give up work? Any work? Useless work, too? Work for a negative goal, too? Isn't the whole statement taken out of context, by any chance? Regarding your addition. Do they actually want a work or a pay?

Concerns about the geometry of the real number line
Genady replied to Boltzmannbrain's topic in Analysis and Calculus
Here is a shorter proof: If q is the smallest positive number, then 1/q is the largest positive number. But there is no largest positive number because we can always add another positive number. Thus, there is no smallest positive number. -
Concerns about the geometry of the real number line
Genady replied to Boltzmannbrain's topic in Analysis and Calculus
In spite of the title, I didn't see anything in this thread that pertains to real numbers. All the arguments, such as non-existence of the next or the smallest numbers, equally apply to rational numbers. Ancient Greeks could discuss and resolve it. -
From the latest local bi-weekly: The OP picture was taken in Lagun, one if the three collection / extraction areas. So, it does not represent the situation in general.

"Humanity, Post Humanity, A.I & Aliens"

And it is not OT, how?
-
It is not what I called sci-fi (as I have explained above.) I call it sci-fi because it is one of millions of other possibilities, and not in any way more plausible / important / interesting than others.
-
I think it is possible. I don't think it is quite possible. No, I do not.

Well, I don't believe that 'scholars' in the past or other similar possibilities. If anything, in the past many things were considered possible, which now we think are impossible, such as perpetuum mobile for example. Advancements of knowledge show, on one hand, what is impossible, and make, on the other hand, reality of what is possible. Regarding AI, I think I've already answered above: "Life beyond our planet"? What is the question?

My definition is quite standard. Science fiction Definition & Meaning - Merriam-Webster: No, this is not what I am confident in. I am confident that the technology, which is called AI now, will not become as intelligent as humans. If some other technology will become so intelligent, or this current technology will dominate human race without becoming intelligent, I don't have opinion on that. What you say is possible. My point is that there are so many different things which are all equally possible that any one of them has extremely low probability of actually happening. That is why I call it science fiction - one of millions of possible scenarios.

What does make you sure it happened? Do you have references?

I know, I know. That's why I could never be a teacher. -
Yes, solutions depend on local conditions. In our case, the entire windward shore, where the sargassum come to, is unpopulated. The whole population, all 22 thousand, live on the leeward side, where sargassum yet to be seen, and in the mountains.
