I like the way you think...or rather, I like your mind entering mine by my brain projecting what you typed into my reality.
But seriously, this post blew me away.

They're discs that store and read data using pits and lasers. The main difference is that BluRay uses a blue laser instead of a red laser, or bluray uses a higher frequency/shorter wavelength of light than DVD for its laser. This allows a BluRay to hold a lot more data than a DVD. Why a DVD only has a SD resolution movie on it but a BluRay can have an HD to 4K movie on it.
Edit: Added Higher frequency and Shorter wavelength.

Basically, blu-ray is denser than DVD. It needs a special blue light to read, hence blu-ray.

Our main sensory organs and how we experience the world is focused around the head, our eyes, ears and nose. When we reach out to touch something we can see our arms with our eyes from the perspective of our head

Exactly. That’s what I said. But the question was “what stops them from declaring independence?”. And nothing stops them. But there will be severe consequences if they do.

Good point! Kind of analogous to a computer. A computer isn't "in" the CPU; it's an integrated system of CPU, memory, I/O devices (keyboard, mouse, monitor, speakers), ports, sensors, etc.
The mind is a function of the entire nervous system, not just the brain.
I listen to a lot of Andrew Huberman, and one interesting thing he covers is how neurons don't just exist in the brain, and they aren't exclusively for processing thoughts. Your gut actually has hundreds of millions of neurons, and they signal all sorts of things subconsciously to your mind!

Reply to ELI5: What are the pros and cons of the American sports franchise-based model? by [deleted]
Americans have tied extremely successful business models (sport teams) to their Education system resulting in billions of dollars in funding for the schools. In Canada, we do not have this.

Might makes right, really. You can set up a micronation, but if the country doesn’t like your existence and is angry enough, they might wipe the floor with you.

In a fair few countries declaring independence will be considered treasonous or seditious, so people very much will be stopped, whether you're in China or Spain.

European model is based on sport and is open to teams to go as far as they want/deserve up or down the leagues. That’s the fundamentals of sport, the way it should be. US franchises can get up and move away to another city or state.

That's a very interesting point, and raises a tangential question: What exactly causes that sensation?
Why do we feel like our head is the center of our body, rather than something like our center of mass (our torso)?
Is it possible to shift that sensation using mind-altering techniques like meditation, sensory deprivation, drugs, etc.? What's behind that, physiologically?

Reply to Eli5 How exactly does Noise cancellation work? That too in such small airbuds by Professional-Ad3441
Sounds can be drawn as a wave, so for one of the simplest examples let's look at a sine wave - just a simple, regular wave shape.
As a simple maths experiment, if we mirror this wave around the horizontal axis so that where one wave goes up, the other wave goes down, and then add them together, they will cancel each other out.
This works with sound in headphones too. If we stick a little microphone on the outside of your headphones so that it detects the outside sound you will hear, then takes that sound and inverts it so it is upside down and plays that through your headphones, the two will cancel out and the outside sound will vanish. If you play the inverted sound alongside the music or other audio you actually want to hear, you get both at the same time - no outside sound, just the extra audio you are adding.
Incidentally, this works really well with headphones, because the microphone can easily detect exactly what your ear will. If you tried this with a whole room, the way sound reflects off of surfaces will mean that the 'noise' sound will be different depending on exactly where you stand, so it is impossible to cancel it out - you could set it up to cancel nicely in one place, but if you moved about in the room in other places it won't work at all, or may make the noise worse.

Does that mean the earbuds use more power in loud environments?

Nothing stops them. They can declare independence all they want. It just won’t be recognized by anyone. If they start making too much trouble, the government will come after them to restore the peace and unity of the country.

Well you warmed the table up by pressing your palm into it for 20-30 seconds, of course the spot will feel warm to your other hand.

Yea. That‘s how it works for every healthy human.
I don’t think even Stone Age people would have assumed anything else without thinking about it.

Reply to ELI5: How do services like YouTube simulatenously stream to thousands of users? by NativeSonSF
On demand videos will be cached locally as well, meaning the file is stored in memory as well as on disk, making streaming to multiple requests even faster. As demand drops, other files will replace the video in the cache.
