I tend to agree, but there might be a subtlety in the question, tested by whom? Take the idea of a universe in a black hole, for example. In principle, it can be tested by an observer falling into the BH, and it can't be tested by an observer outside the BH, if I am not mistaken.

I understand your description and there are no problems with it, but I am not clear about what it proves. I have tried a few posts above to reformulate the problem in a - hopefully - clearer way. Here I write it again: You have a plane with the grid points on it as described in the OP. Somebody gives you a transparency with an inkblot on it. You position the transparency on top of your plane in such a way that the inkblot does not cover or touch any of the grid points. Prove that such a positioning exists for inkblot of any shape as long as its area is less than unity.

This fairy tale has quite a different take on plucked out eyes:

To ease the discussion, let's name all the important pieces: Given: a+b+c=6, d+e=3, f+g+j=5. The question is: a+i+h+j=?

OK, it's clearer now.

What if I make and wear shirts with a sign like this: ?

Exactly. What is a cup-o-tea for one might be a very hard work for thousands of others.

Fresh from the meeting: Live Updates: Berkshire Hathaway Annual Meeting 2023 (cnbc.com)

Reporting a failure. This morning, I've extended my hand as far as politely possible. They gladly shook my hand ... and then jumped on and hugged me anyway

Some work has to be hard, there aren't enough machines in the world with the skill sets to do all of it. The full sentence in the context would be, "Work doesn't have to be hard in order for a system to allow to earn more money." IOW, the amount of money earned is not necessarily positively correlated with the hardness of work done. Of course, it depends how the 'hardness of work' is measured.

I have already thought about it and, moreover, have seen it in action. This is not a discussion. I have made my mind: you are a troll. Goodbye.

You have managed, again, to annihilate any wish to discuss with you. You said, you are interested in the discussion, and in a few posts you kill it.

So?

"moral principles of Islam" It stops right here.

If it is neat, it should be written down.

Perhaps I shouldn't take up this kind of puzzles because English is only my third language.

If this was for me, it was a waste of your time. I don't discuss videos.

Fine. What I don't understand though is, when an interest is moral and when it is not. IOW, when an interest constitutes a fair compromise vs the money earns money issue.

OK. In the above scenario, doesn't your money earn money, namely, the 5%?

I agree with this. However, there is a subtle point. You want 10% interest, but the other party agrees to pay only 5%. You accept. Are you forced to accept in this case?

Yes. "You work today, but you don't need money today. So, you agree to get paid later, with interest." Is this deal free and moral?

But I don't have one myself. Will start practicing tomorrow . I will go for this, I think. (I am getting desperate.)

[repetition] You didn't comment on @TheVat's other suggestion. With a little modification, something like line 'n' grid ?

Very impressive! These threads could be merged:

I came from a handshaking culture. Men, women, children greeted each other by shaking hands, unless they were family. We used to make fun of kissing Brezhnev (brezhnev kiss - Bing images). Then, I started moving from place to place and met other kinds of bodily touching between strangers: a kiss, cheeks touch, three touches, hugs, hugs and kisses, etc. I feel very, very uncomfortable with all of them. I was so grateful to covid for stopping people doing this, but now it is coming back. I don't want to offend others, but I also don't want their bodies to come too close to mine. Any suggestions?
