Although I can learn and understand about Bitcoin and how to invest in it, I do not understand the various aspects of Bitcoin, i.e. technical aspects. So how can I learn about technical aspects very easily in a short time. For example: Bitcoin block.
It's not easy in the sense that it takes time, thought, and willingness to practice. Technical knowledge is expensive because not everyone who owns Bitcoin understands the technical aspects.
In this forum, only certain people have a good understanding of Bitcoin's technical aspects, as you mentioned. If I may mention their names, I would name a few who I consider to be experts on the subject. The rest of us here only have general knowledge about Bitcoin, myself included.
There is a board for technical discussions on this Bitcoin forum. You can get involved there by reading each of the discussion posts they have created. I think that can help you gain knowledge.
That's all I can say.
