Don't forget to quote me!
I can't find this paper again yet. (I'm quite busy: revolution, ongoing war, problems with health, my father died, politics, delivery for 1+y long project in less than 2 weeks, etc.)
This paper complimented view I already had in my head (everything is particle, surrounded by spherical wave, and propelled by vibrations/noise), because now I know that Universe is very simple thing in general. Nothing complex can survive in infinite time. This mean that on lower level only extremely stable (simple) systems can survive, because time is very fast on level below. On our level, we can find temporary complex systems (we live at one of them, and we itself are another example). On level above, it unlikely that we will find a complex system, chances are very low, thus what is see around us should continue for very long time and space.
Sometimes, I need to switch from supported release to legacy release of drivers or switch back, because of NVidia politics to remove old drives from binary.
Recommended command for system upgrade is `sudo dnf system-upgrade download --refresh --releasever=30` then `sudo dnf system-upgrade reboot` .
My bad. I'm not familiar with this.
(Beware, my English is weak).
I had year long discussion about similar topic by email, so I see nothing exceptional there. If you have sum(sin(x_natscale)), and you will start to play with scale, you will see sinusoidal graphic, freq=asin(scale). Object formations in space usually have round shape, so it's will be same in 3D. :-/
Why? Because our formation exists for very long time. Let's play simple example: we need a 1d function f(x), such as sum(f(x_nat*scale)) newer produces infinite sum or singularity. Physical meaning: Our Universe exists for infinite time, but all matter is not attracted into one single point of infinite mass, so it's not possible.
The simplest such function is sin(x) or cos(x). If we will try to play with scale, we newer be able to make infinite sum, because Pi is irrational number. The closer our scale will be to Pi, the larger peaks of sum we will have.
In real life, this influence diminishes after some point, so, for example, size of nuclei has influence at frequency (distribution) of chemical elements, but it has no influence at macro objects, so function becomes flat and sum must rise (e.g. collapse into a black hole), then next level begins.
So, it looks like at some point, these formations cannot be bigger, or we cannot see light from them, e.g. because they are so massive, so light cannot escape them. If so, we have lower limit of formation size we can see at this distance, dictated by geometry (angular size) and luminosity, and upper limit dictated by nature, e.g. upper mass of formation of such size (upper density).
It's like in our galaxy: we can see stars, but cannot see black holes (too heavy), lone planets and smaller objects (too cold), and far away objects after certain distance (too small luminosity). IMHO, angular power spectrum of visible stars must show distribution similar to CMB or distribution of chemical elements.
It's temporary. With more data, we will have more and more exceptions, which cannot be explained by patches to mainstream theory.

Lifetime of larger objects usually is much larger than lifetime of smaller objects, so, as we increase scale of x,y,z, t axis should be increased proportionally.

Modern version of tired light. A kind of resistance for light, which causes loss of energy proportional to light frequency. See below.
> How do you account for the CMB angular power spectrum[1][2] with your "tired light"?
I see just aged spectrum. IMHO, it's helium. :-/
My own idea is that photon itself has no mass, because it just wave of energy, but vacuum of volume of photon has some non-zero mass.
As analogy, water wave has no mass, but water has, so water, which forms wave, can be affected by external forces, e.g. gravitation of Moon and Sun, thus form of water wave can be disturbed by these forces. LIGO demonstrated that light can be affected by gravitational waves, so these gravitational waves, in form of constant noise, can disturb shape of photon, so photon will lost small fraction of energy to gravitational field.
Moreover, as EM force, photon should be affected by fluctuations of quantum foam, which are happened nearby. In this case, photon will lose small fraction of energy to these virtual particles.
For me, it's clear that Universe has no bounds, so objects after Visible Universe is invisible because of geometry - we just cannot see objects which are sending less than 1 photon per hour per square meter, so there was no Big Bang less than nanosecond ago at Universe scale, it's just aging of light, so background microwaves is just aged light from distant objects.
To make substring in some other languages, you need to store pointer to beginning of the substring and length of substring.
To make substring in C, you need to store pointer to beginning of the substring and put '\0' into original string.
It's well known and long standing problem. Rust the Language allows proper enum, but Rust the Compiler cannot pack enum into single value, as in C.
Example:
#[repr(C)]
#[repr(i32)]
#[derive(Debug)]
#[allow(dead_code)]
enum E {
A,
B,
C,
Unlabeled(i32),
}
fn main() {
{
let v: E = unsafe { std::mem::transmute::<(i32,i32), E>((0,0)) };
println!("v = {:?}", v)
}
{
let v: E = unsafe { std::mem::transmute::<(i32,i32), E>((1,1)) };
println!("v = {:?}", v)
}
{
let v: E = unsafe { std::mem::transmute::<(i32,i32), E>((2,2)) };
println!("v = {:?}", v)
}
{
let v: E = unsafe { std::mem::transmute::<(i32,i32), E>((3,3)) };
println!("v = {:?}", v)
}
{
let v: E = unsafe { std::mem::transmute::<(i32,i32), E>((3,55)) };
println!("v = {:?}", v)
}
{
let v: E = unsafe { std::mem::transmute::<(i32,i32), E>((55,55)) };
println!("v = {:?}", v)
}
}
Output: v = A
v = B
v = C
v = Unlabeled(3)
v = Unlabeled(55)
v = AExcept for taxes. Anybody, who will live on Earth and be above average, will need to support other living beings (humans, animals, fish, forest, grass, birds, insects) with his taxes, otherwise we will have dirty cloak with few billions of angry and hungry living beings, which can dig you out of any bunker.
At Mars, it will be hard to survive without external support for about century, but much lower taxes and self selection of educated people with high IQ can make it booming.
Just call it "C20", and they will learn it in a week.
You will be pushed. J
Seriously talking, if I need to wrote error checking code with user visible message, usually I'm trying to add a suggestion to user how to resolve problem. It's good UX.
