I think that you have to appreciate that while you are learning, you start from the ground up. That means that there are some things which at the beginning you have to take as read, because the details of why they are true will be beyond the stage you are currently at and will be explained later.
Asking questions while learning is excellent, but asking questions about advanced concepts while you are trying to master the basics is a recipe for disaster.
This can be incredibly frustrating, because if you are an intelligent, enquiring individual you will always want to go further than you have been taught. The only real advice is to take the time to learn the basics. A lot of what you are questioning now will be explained as you advance; this is purely because once you understand the foundations, you can begin to understand the entire building.
It may well be that as you advance you discover something entirely new and unexpected. I hope you do, because that is how knowledge moves forward. But remember that your new theory has to explain things that have already been observed. And understanding how observed things work the way we think they do takes a lot of work.
It sounds to me like you have an enquiring mind, and a willingness to challenge the received wisdom. If you can combine that with study and understanding (not necessarily acceptance) of the way things are viewed today, you have an incredibly bright future ahead of you. I wish you all the best.
