OKAY KISSBLR YOUR PHYSICS NERD HAS ARRIVED
I've decided to take on the task of explaining my little yap in this comment:
Also I'll be simplifying a lot of things so feel free to explain them in detail in reblogs/comments :3 /g /nf
First of all, wtf even are quantum physics??
Quantum physics are a branch of physics which focuses on the subatomic, the nitty gritty wonky shit we can see under microscopes
Let's start with this: did you know that the atomic model made by Schrodinger actually is the most accurate one we have (so far)?
(the last one in this picture)
As you can see, the atomic model evolved over time, going from Dalton's ball to Schrodinger's cloud
But why the hell is it a cloud?
It's not like they turned out to be actual, negatively charged clouds instead of subatomic particles, no. It's due to electrons being in constant motion, meaning we can't tell exactly where they are and all we can do is bet that they're in certain positions (which got calculated and stuff blablabla, tons of probability talk mimimi) until observed
Which brings me into another point, superposition!
When we say that something is in superposition, we mean that it's in an unclear state until observed and as an example I'll use the famous Schrodinger's cat...man
(I put it together while writing all of this btw)
Imagine the Catman in a box with a poison which will kill him once a radioactive atom connected to it decays (usually by ejecting either a part of its nucleus, an electron or a gamma ray but which type of decay would happen here is irrelevant). Until we open the box to check if he's dead, or alive, we can't be sure
And yes, that makes him both dead and alive at the same time (which I'll get to later)
That box situation puts him in superposition and thus checks off Schrodinger's Cat(man) paradox at once :3
Also no Catmen got hurt during the experiment ":3 /silly
Staying with superposition for a moment longer, we can move to the observer effect (or as I worded it in the comment: "how observing something influences the outcome"). For it, we gotta get to the double slit experiment which is the best example of the observer effect in action!
The double slit experiment is about how doing something can have different results depending if its process is being observed as it's going on
When observed and documented, the experiment gave a fairly straightforward result, with the conclusion being that electrons behaved like the particles they are:
But, once not observed and only documented afterwards, it gave a very... intriguing result, with the electrons acting more like waves than particles:
(same source as with pic above these two)
Now, it may either mean that the particle-wave duality of, well, particles is real, also that maybe the photons messed with the trajectory of the electrons which made them act "normal", or maybe that a conscious observer somehow messes with reality itself?
Okay, don't ask me which one it is (it's not the last one don't be ridiculous, the observer they used wasn't a sentient being but a machine) but it surely proves that us observing something will change the results!
Now going back a little, remember the part about Catman being both dead and alive? Yeah!
That relates to the concept of quantum immortality (and quantum suicide BUT dw there won't be any actual talk about kys /info)!
Quantum immortality is a concept rooted in quantum mechanics and discusses the possibility of living seemingly endlessly through the splitting of the timeline whenever you're in a deadly situation
And quantum suicide is when you're in the timeline that ends with you being dead
(Yes, it relates to the many-worlds interpretation which is about how there are endless versions of our world which "split off" whenever something happens, creating pretty much a multiverse that could be proven scientifically... maybe... someday)
And now my favorite quantum twat and his family, STRING THEORY AND M THEORY
String theory states that instead of elemental particles (e.g. electrons, up and down quarks, gluons, higgs bosons, electron neutrinos etc.), we have one dimmensional planck length strings in their place which vibrate in a certain way that results in them functioning as specific elemental particles!
Basically, everything being made of strings and not particles at the subatomic level
However, we can't prove it directly (via observation), because in order to see if they're here or not, we'd have to shrink photons so much, we'd create kugelblitzs (black holes made out of heat/energy/radiation) and see nothing
The M Theory encompasses the various versions of "the superstring theory", which tries to make quantum physics work with all fundamental forces (strong & weak nuclear forces, electromagnetism and that pesky gravity). Of course, gravity has to be a diva and make things extra complicated (which, btw, made various theories about it spark up, such as the theory about gravity being made of particles called gravitons)
The big M stands for many different things and here you can say it's "magic" or "mystery", or "meme" even tbh (my fav is Meow) /silly
It was really fun and took me a lil while X3333!!!!
Ngl, most of it is actually from memory with fact checking to see if I remembered things correctly or not /nafx
If anyone has any questions about these or wants to know more about atomic, subatomic, or quantum physics, feel free to ask me about it :3<
And if I won't know it, I'll do some research and then reply so dw :3c
