More Crackpot Magnets on YT
One hope is self-distraction: the amount of misinformation will be so large that it will become a white noise, which people will have no choice but ignore. Also, competing sources will engage in wars between themselves, making even more noise.

I don't think they care. They are autotrophs.

Why are you concerned about this? I am not. Maybe I am missing something.

Civilisation Efficiency Ìndex or Ìndex of a Civilization’s Strength. Opinions are welcome.
Let's assume there is a suggestion for an index. How it can be tested? What is a criterion to check if this is a good suggestion or not?

Civilisation Efficiency Ìndex or Ìndex of a Civilization’s Strength. Opinions are welcome.
I didn't see Arts in the index. OTOH, there is Blockchain & Crypto. Weird choices.

Physics and “reality”
I did not ask about acceleration. My question is about the force. The consideration was, is the force frame dependent? The charge is not attached to the frame. The frame is not a structure. You did not answer my question. But do not feel obligated.

In which accelerated frame the Coulomb force between two charges becomes zero?
-
Physics and “reality”
How about Coulomb force? Is it frame dependent?

Humanity, Post Humanity, A.I & Aliens
The reference to Asimov is appropriate because this topic, in my opinion, is no more than discussion of science fiction with a straight face, and as such is good for entertainment purposes.

I've just looked up his name and read the Wikipedia article. I don't think he is worthy of your attention, @joigus. Not more than Deepak Chopra .

Physics and “reality”
Are you sure? If you have a spring stretched between two walls, its force on the walls is frame dependent?

Who did the basic works of math?
Chinese didn't need writing earlier because they have a superior memory. They started using it later when they decided to deal with others who could not remember very well.

Thanks. Unfortunately, I cannot fully comprehend contents by listening because of a form of APD. Do these lectures exist in a written format?

Physics and “reality”
I don't think it will. For a full and uncompressed description, you will have to simulate not only "every tree and animal and rock and chewing gum wrapper etc." but also every molecule, atom, electron, etc., IOW, to simulate complete quantum state of the system. But - here comes the punch line - no cloning theorem tells us that this is impossible. Thus, abstraction is inevitable.

Physics and “reality”
Imagine that instead of falling toward the Earth you are on a free trajectory around the Earth. You don't need a parachute, you are not going to hit the ground, Earth is not coming toward you, etc. And there is no force.

What is likely to be the underlying cause of my nosebleed?
What makes you think so? In fact, I, my family, and all my friends do not normally or commonly experience dry air and nose picking.

Physics and “reality”
Fields are present in laws of physics. How they are not real but forces are real?

Concerns about the geometry of the real number line
Yes, they - [0.1] and [0,1) - are very different. Another layer to take off has to have a finite depth.

Physics and “reality”
I see leaves moving with the air, but I don't see any force.
-
Physics and “reality”
Do we ever observe a force?

Humanity, Post Humanity, A.I & Aliens
You didn't mention one solution which does not require new physics. If we could get very close to the speed of light, travel anywhere wouldn't take too long for a traveler. For example, with a speed of 0.999c, she would reach the next star in a couple of months.

neutrino oscillation
There are couple suggested mechanisms on how neutrinos acquire mass. This is not specific for neutrinos. Other particle masses differ between generations as well. Electron - muon - tauon. Down - strange - bottom quarks. Up - charm - top quarks. This is not specific for neutrinos as well.

In this article, the author argues that general AI cannot be fully controlled: Honestly, I couldn't get through it and so I don't know what the arguments are and how convincing they are. Good luck! 2008.04071.pdf (arxiv.org)

neutrino oscillation
IIRC they oscillate because their mass and flavor do not commute. This is logical and simple. It is not new though.
