Answer: 76925 + 70478 = 147403

Thanks. I understand now what the conversation is about.

I have difficulty to find any example of observable concept / element of a theory. All examples that come to mind seem to be rather non-observable. Help.

@Commander I see you often post puzzles and I hope you are good in solving them as well. I am still looking for a better solution for this one: If you can help with it or have questions about it, please post in that thread. Thanks.

Will torturing AI be a crime?

So, I made a mistake "eliminating" D = 9. No wonder I don't remember how I did that...

I thought that this is what you mean. It is a common effect for sure, but it is also individual. In my case and in case of several people I know, it does not work, by choice.

I've eliminated the other possibility, D = 9, but I don't remember at the moment how I did it.

Trying to find out how the computer is programming me.

Are you sure it has an answer?

SFn?

I speculate that being smarter than us, AGI will invent a way around any firewall we can come up with.

We do notice it. See here (Gravity of Earth - Wikipedia😞

D = 0 F = 1 T > 5 R > T Not too many possibilities left to check manually.

Yes, there is. There are many ways to lose control, I think.

Yes. v2 = 1 - m2/M2 M - initial mass m - final mass v - final speed, in units of c.

I don't think you need an equation for this. If you convert the entire mass to something massless, like e.g., light, then that something moves with the speed of light. Regardless of the initial mass.

Ah, I didn't realize that you refer to that post... No, the barrier is independent of the frame. In any frame, the faster you move the more difficult it is to add speed.

Alright, this is clear. What is the question?

If a neutrino moves at 0.99c in lab frame and we move in opposite direction at 0.01c in lab frame, then we move at 0.9902c in neutrino frame.

Yes, of course we are.

What do you mean?

It is quite possible that there were on this planet, more intelligent and less aggressive Homo species, but they went extinct, perhaps with our help. Then we are not.

We build devices that function well without being enclosed in "envelopes." I assume that simple forms of life could evolve to be like that as well.

I've looked through the paper. It appears that the "space-river model" is not, and it does not intend to be an interpretation of GR. It rather It applies only to a limited set of reference frames / observers, in a limited set of space-time geometries, e.g.,
