More Crackpot Magnets on YT
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.

Civilisation Efficiency Ìndex or Ìndex of a Civilization’s Strength. Opinions are welcome.
Any such index will be soon obsolete if it doesn't take in consideration that civilization evolves. It cannot take the evolution in consideration because evolution is unpredictable. Ergo, any such index will become useless soon.

What is likely to be the underlying cause of my nosebleed?
I don't see how "dry air and nose pickling shouldn't be the cause of nosebleeds" is suggested by "none of them said that they had nosebleeds". I can only see how the latter suggests that the nosebleed condition is not very common.

The OP is copied almost verbatim from Fact! The Sun is producing only a third of the neutrinos expected Hold up your thumb. 100 billion neutrinos are passing through your thumbnail every second. 8.5 minutes ago they were in the heart of the Sun. Solar neutrinos are a by-product of sun - Intresting facts. - Quora
