Why do you think the Moon often appears in magical stories (from a physics point of view, of course)?

Worldline and Geodesic in General Relativity

Oh yes, I have prepared a little surprise and expanded the topic. Actually I realized that geodesics are not the whole story I wanted to tell.
I dug up my old favorite book on GR and remembered that there are also worldlines.

So. Every object leaves a trace in spacetime. This trace is called a worldline. A planet, a satellite, you right now. Everyone has their own line that shows wher...

New game👀

I decided to add a little interactivity, a day before the post I will ask you a question related to the topic of the post. I think it will be more interesting and the information will be better remembered.
Let's begin!

A geodesic is the most direct path in space-time.
There are three types of geodesics:
1.time-like,
2.light-like
3. space-like.

Now guess for your...

How the fuck does light that has no mass still bend near a star?

In Newton’s classic gravity works only on masses. So for a long time people thought light doesn’t give a fuck about gravity.

But Einstein said you think wrong.
Gravity is not a "force" that pulls something. It's the shape of space time itself.

Light always goes on the most "straight" path only the thing is in curved space the "straight" path can look curved.
In GR(G...

How masses bend our Universe?

If SR(Special Relativity)is about moving trains and cleavage, GR(General Relativity) is when the train itself bends under the weight of your ass.

Here everything bends, both space and time.

Einstein looked at Newton’s gravity (masses attract because… well, just because, don’t fuck my brain in the morning)
and said:
No, guys, masses don’t attract, masses BEND.

Welcome to relativity, where motion ruins everything

I decided to tell you a bit about Einstein’s theory of relativity (yes, there are two versions: special and general (you’ll get why later).
Today I’m gonna talk about inertial frames of reference.

When Einstein said that time isn’t universal, people freaked out, to put it mildly.
Like… seriously? Even time isn’t stable in this cursed world?

To understand how he g...

Fermi Paradox: the numbers dont match reality

In 1961, Frank Drake proposed an equation to estimate the number of civilizations in our galaxy capable of making contact:

N = R* × fp × ne × fl × fi × fc × L

There are many opinions about most parameters, but here are the values Drake lused in 1961:

R* = 1/year (one star forms every year)

fp = 0.5 (half of the stars have planets)

ne = 2 (on average, two...

Btw im preparing the post, soon....

If you look at a photon does it change its trajectory?

Sounds like you are some big D boss influencing a photon.
But what really happens when you "look" at a photon?
To see it the photon has to hit your eye and disappear, being absorbed by the molecules in your retina. Basically you just "ate" it with your eye.

But where does the myth come from?
From quantum physics and the famous double slit experiment.
No this is not about doub...

The Sun breaks physics

For nuclear fusion to happen in the Sun (like when two protons fuse into a deuteron), they need to overcome the Coulomb barrier (named after this smart dude, Coulomb), meaning, the repulsion, because both have a positive charge.

It’s like trying to push two same magnetic poles together. And the repulsion between protons is seriously strong.

According to classical physics, for t...

Casimir effect.

Two perfectly smooth metal plates are just standing there - in total emptiness.
No particles. No photons. No pressure.

Now get ready to freak out:
They start attracting each other.
On their own. Because between them… there’s nothing.

This is the Casimir effect.
Welcome to quantum mechanics, babe😏

See, the vacuum isn’t actually empty.

I don't use iphone My friend made these photos for me

Omg.... finally....I was sure something wrong with Patreon platform, but they just don't allow to post with .IHEC format

One more reason use Android😏

🌠

Well...

I have no idea what happened but i can't upload any pics here....

I have one more cute stuff ❤️🩷💜

(Fight with my fear to show my cute side)

How would a black hole eat you?

You’re just floating through space.
Ahead: a black hole.
Not a "hole" like a tear in fabric.
This is a region of space where gravity is so strong, not even light can escape.
Yeah, yeah, we’ve talked about that many times....

The border around a black hole? That’s the event horizon.
Until you cross it, there’s still a chance to turn back.
But once you’re past i...

if a white hole was a person🤍🩶

Btw you can see how I made my content

A black hole is not a cosmic vacuum cleaner.

When you hear “black hole,” your brain probably draws something like a bathtub vortex sucking everything in. Spoiler: that’s a myth. No, it’s not going to “suck in” you, Earth, or Saturn. Relax your balls😏

A black hole is a region of space where gravity is so strong, not even light can escape, yeah yeah, you've heard that one before. Sounds all mysterious and dramatic. Bu...

The hardest thing for me right now is showing the sweet part of my personality.

These little ears on my head: Ihad to force myself to post photos with them on Instagram, where everyone can see that I look cute. I immediately associate that with childish behavior, immaturity. I feel ashamed.

I can't accept it. I'm always the grown-up one: sexy, serious, smart, decisive.

And this…
it feels vulnerable and weak, silly, immature, infantile.

Because ...

Sorry for no reply, I will do it later! And yes, if you have any suggestions about new posts, just tell me here

Standard model part 2

I've already talked about the Higgs a million times, you're probably sick of it by now. Higgs this, Higgs that… yeah, I fell in love with the guy. Shame he's dead… solid dude.

But anyway, one more quick recap: the Higgs gives all particles mass via the so-called Higgs mechanism. It basically ties particles to the Higgs field, like a balloon vendor tying helium balloons to her cart. ...

The Standard model

"The Standard Model", people often think it's like the "basic version" of physics or some intro-level shit. But no, babes, it’s the most expensive, complicated, and successful theory ever cooked up. Yeah, they literally built the collider just to finish it properly - through the Higgs. That little guy was crucial.

It explains almost everything... except for the stuff we actually care ...

The Sombrero Hat, or How the Universe Might Suddenly Drop Dead

You’ve probably heard of the Higgs boson: that particle that's supposed to “give mass”.
But the story’s got a dark side. Like, really dark.

Picture a Mexican hat- a proper sombrero. That’s what the Higgs potential looks like if you plot it.
Don’t fry your brain with equations, just go with it.

In the center is a peak. Around it - a ring of low points. Right aft...

If only the universe knew that from its particles we can create such a booby cup👀
