Different time for your head and body
I will start with the most interesting part right away. Your hands and your head live in different times. Your head lives in the future compared to your hands.“Lol, are you fucking insane?”Yes, long ago, but thats not the point.The point is gravity. Or more precisely, how gravity affects time. The closer you a to a massive object, like the Earth in our case, the slower time flows. Thats what Grandpa Einstein said. And it always works.But the difference is so insanely tiny that a normal human...
Finally......
The last post about the Universe. Im so damn tired of this topic. After the first three minutes the Universe finally cooled enough to do anything remotely useful, or at least what passes for useful at that point. Protons and neutrons started sticking together into the first nuclei. The result was basically a three item menu: hydrogen, helium and a tiny hint of lithium. This set🍣🍙🍘 became the foundation of all chemistry for the next 13 billion years. Even now cosmic rays still contain e...
The universe history is ending
Honestly Im so fucking tired of posting about the Universe. I already covered the first fractions of a second and that was the only interesting part. After Higgs there is just a long string of boring phases............First came the lepton era which was basically hot diarrhea made of electrons, positrons, neutrinos and photons. A bit later the temperature dropped and during the hadron era the first protons and neutrons finally appeared. Then electrons and positrons almost completely wiped each o...
Big D*ck in town(Higgs boson)
At around the 10⁻¹² second mark, the Higgs showed up and handed everyone their fucking mass.Before that, particles were massless, just like photons.Everything was way too fast, way too light, and way too full of itself. None of the rules we have now worked back then, obviously. Quarks were flying around like insane sparks, electrons were just blobs of energy. W and Z bosons (two of the most important bosses today, by the way, real heavy hitters), and photons, just like now, were outrunning ...
Little bit more about strong force and quarks
So yeah, the birth of the quark stuff happened between 10⁻³² and 10⁻¹² seconds.Holy shit, that’s a "whole 20 orders" of magnitude, quite a ride😮💨And yeah, the quarks were massless back then, since the Higgs hadn’t shown up yet...Also, I forgot to clarify last time: the strong force had already split off from the other two (the weak and the electromagnetic) at the 10⁻³⁶ s.The funny thing is the strong force’s job is basically to hold quarks by the balls with gl...
The era of inflation, when everything stretched the fuck out.....
So, time moved on, after 10⁻³⁶ seconds.From 10⁻³⁶ to 10⁻³² secondsX and Y bosons fucked off, antimatter and matter stopped annihilating each other, and the Universe was left like this: a huge chunk of emptiness filled with a fuckton of energy, but no particles, no light.All that energy sat in one fucking field, physicists call it the inflaton. Well, that’s not even certain. A field that literally stretched the Universe until it said "stop it, please".And not just stretche...
Mad Max...sorry Matter-antimatter Madness
So, let’s fucking continue.Now we’re talking about the time between 10^(-43) and 10^(-36) seconds.First question: why the hell even bother with such microscopic fractions of a second?Because physics was changing insanely fast back then, and every tiny stage matters.I want to build you the whole puzzle piece by piece.Today I’ll tell you about the reason why we even exist.Because it’s not as simple as “the universe appeared and here you are.”Nope. In those microscopic fractions of a se...
That very time in the Universe when you could sum up your ass and your face or someone else's face
I start to tell you the fucking amazing story of how the Universe was born.And of course, I’ll start with the real mind-fuck, the very first moments of the Universe, before the first 10^(-43) seconds.To give you a sense of scale: 10^(-6) is one millionth of a second, six zeros after the decimal, 0.000006.Now imagine 10^(-47). That’s 46 zeros after the decimal.OK I WILL WRITE0.00000000000000000000000000000000000000000000001 SECONDYeah. That kind of shit, buddy.That instant is called the Planc...
What the fuck is this h?
And why the hell is it so important?Planck’s constant is like the lower limit of the Universe, the step of its pixel.Everything you see, hear, touch, even think, yeah, fucking think.you think in quanta....Everything is quantized by this microscopic dude h.Here’s the formula where it all started:E = h*νThe energy of radiation is proportional to its frequency.Tiny, almost zero.But it’s exactly what separates the continuous "classical" from the discrete "quantum".Planck’s c...
Wave function and spin of ē
Now let’s dig a bit deeper into the structure of particles.Spin is basically like a built-in quantum magnet.In the Stern-Gerlach experiment(on the pic), electrons are sent through a magnetic field.Before the experiment, the logic was: if each electron has its own little arrow, the beam should smear into a stripe. Arrows could point in any direction, full 360°.But in reality the beam always split into just 2 spots. Everyone freaked out, again physics didn’t match the expectation, lol. Turns ...
Spin: a property that will fuck your brain
An ordinary person thinks: if a particle is small, it spins like a ball.But no. Spin is not rotation.It is a built in property of matter, like gender that cannot be changed:for the electron it is always 1/2for the photon it is always 1for the Higgs boson it is 0Now the trick, you will freak out:The electron has spin 1/2. This means that to return it to the same state you need to rotate it not by 360° but by 720°.Yes, this bastard requires two full turns to “feel the same again”.Imagine a c...
Why do stars twinkle
Stars send us light for millions of years. This light arrives as almost perfectly flat "wavefronts", basically like parallel lines. But in the last 100 km, in the Earth’s atmosphere, everything goes to shit....(Yes, as you told yesterday, smart asses😌😌)The atmosphere is not fucking uniform, there are different temperatures and densities. Where the air is warmer, it’s less dense and the refractive index of light changes going from cold to warm and back.Formula for this (very sim...
Why did the Moon become a symbol of magic?
Tonight is a blood moon🌒I made a short overview of what people usually associate the Moon with in movies and in real life.TidesInterstellarIn the movie there is a planet with enormous waves. This is a hypertrophied version of what the Moon does on Earth. Its gravity lifts oceans by meters. For ancient people the sea that obeys the Moon was pure magic. Without physics there was no other way to explain it.MoonlightHarry Potter (Lupin)Werewolves always react to the full moon. Physics explains it...
