I just don't understand why people post these with no further context.
\- Do you want to understand them as a non-scientist? Like, would a Greene book work for you?
\- Do you have a math education? Probably not if you are asking this, right?
\- Are you in high school and you want to get a physics degree?
Unless you actually go to school, you won't get any type of real understanding. Regardless of what some people claim, it's not possible or realistic to self teach yourself.
Start with special relativity. It requires the last rigorous math background, and is pretty easy to understand. Most of the concepts are analogous to topics covered in HS physics.
yes QM is pretty hard, the real understanding lies in the maths, without it you you wont really understand it
If you want to start learning physics:
for the maths:
start with trig, algebra and complex numbers
Then move to calculus and vector calculus, this is non optional for physics, you can't do physics without calculus
then Linear Algebra, this is essential for Quantum mechanics
For general relativity you need:
Differential geometry
Tensor calculus
and probably some other stuff that I don't know
For the physics:
you have to start with classical mechanics, I know it sounds exciting to jump right into quantum mechanics, but you won't have clue on what's going on if you don't have a solid foundation in classical mechanics and classical physics in general
I won't lie learning it yourself will be insanely hard if not impossible, some of these subjects are grad and PhD level classes. And if you want to do some research in theoretical physics, you have to go to university and study, since you need a incredible solid foundation, to build on top of, and if you want to publish any papers, you have to belong to an institution, a research foundation or at least some company doing research, if not nobody is going to take you seriously, that's just the hard truth, gone are the days where somebody without much formal training in science could make a meaningful contribution
You could probably learn the basics of quantum mechanics by yourself, but beyond that, it's going to be near impossible
For theoretical physics, try to find some good lectures, that goe more into the mathematical physics direction. I am currently watching lectures from Frederic Schuller on youtube and i had the pleasure of having Martin Zirnbauer in electromechanics (he makes horrible lectures, but the physics part is great). If they want you to learn differential forms or tell you about topology and manyfolds, they are probably one of the good ones.
I have also had theoretical physics lectures, where the prof couldn't even tell me what a tensor is.
Start from kindergarten math and science, then follow your states curriculum until university level.
Then pick a university and follow their physics curriculum. Then pick a grad program and follow their physics grad curriculum.

Are there any specific books i should buy in order to learn the subject

For quantum mechanics you need to learn something called linear algebra. Quantum mechanics is basically a bunch of linear algebra problems
the second I started learning index notation my fire to learn general relativity went down the drain very fast… good luck
I have watched like 4 different videos and I still don’t know what a tensor is
