Yesterday I was preparing for my Saturday meeting with my ex supervisor and I found the article about first stars numerical Simulation. So I can simply explain what was going on many many years ago.....(200-400 millions years after Big D... Bang)
When the Universe first began to evolve, almost everything in it was hyd...
the continuation of dark matter topic is LaTeX again.....
I promise it's easy😌😌

Well I divided the post, bc it was toooo big this morning (oh no😮💨, I joked even didn't realize I did it).
Next time I will show it with the Friedman equation.
Dark matter is not directly observable, but its influence can be measured through various astrophysical observations. The main methods confi...
I created the overleaf document, bc it's impossible to put formulas here
You also can see I Know TeX, haha
Enjoy!

You've heard of dark matter (no, antimatter is different)?
Today I thought about what would happen if you swapped ordinary and dark matter.
But to make things simpler, I'll give you some analogies.
Imagine the Universe is a house you're building. There are two important materials in this house: ordinary matter (b...
1. Classical Mechanics
Any movement of bodies follows Newton’s laws. During sex, the following principles apply:
Friction - a key factor in the process; without it, nothing happens. It can be considered a dynamic force, which is reduced by natural lubrication or special substances.
Momentum and energy t...
Last time I told you about eV, now you a smart enough to understand this post😌😌
1. Low-energy particles
Energy: less than 10⁹ eV (this is roughly the energy of a single gamma particle: stronger than a visible light photon, but still no superhero).
Example: these particles have about the same ener...
An electron-volt is a unit of energy. But don’t think it’s some kind of super-powerful thing. It’s actually the smallest and most humble unit of energy physicists use because in the microscopic world, big numbers just make your brain hurt.
How does an electron-volt work?
Imagine you have a 1-volt batte...
Rigidity of a particle is its ability to "punch through" magnetic fields(Yes, in space we have sooo fucking big magnetic field. Galactic one)
Rigidity is the ratio of the particle’s momentum(kinda speed*mass, except photon ofc) to its charge. The greater the particle’s energy (momentum) and the smaller its charge, the ...
Surely you've wondered (well, maybe not always, who knows, but I find it fascinating) why no two snowflakes are alike?
The secret lies in their unique journey of turning water into ice. It’s impossible to create completely identical conditions, only similar ones. Even temperature, which might seem stable, actually fl...
There's a gym in space too, but they don't use it to build big ass — they use it to avoid losing it...👀

The closest place to Earth where snow falls is Mars. The average temperature on the Red Planet is a balmy -60 °C perfect for snow formation if you like your winters Siberian and your frostbite instant. But Martian snowfalls are nothing like the cozy, fluffy ones we know, thanks to its thin atmosphere and otherworldly climate...
