Thank you, George. I really appreciate your feedback on my explanations - it makes me very happy! I'm glad you found it useful and I hope it will help in your future articles.
I read your article on impossible galaxies and you make some interesting points (and the article itself is great too!). You're right that there may be explanations that sound impossible now, but could revolutionize our current understanding.
One idea I got from there is the following. In Einstein's general theory of relativity, space and time are "connected". As we discussed, there may be more than 3 spatial dimensions (2D, 3D, 4D, 999D...); but also there could exist multiple time dimensions (we think that there's only future, present and past - but what if there is some other time dimension? The one that goes "sideways"). The curvature of space-time could cause time to flow differently for these "impossible" galaxies (example is gravity - near the black hole, time "slows down"). Maybe some "aliens" or other objects in higher dimensions are interacting with our universe, and we just don't understand it.
Regarding your question about "upper limits", you have understood everything correctly - I meant that there is no limit to dimensions (2D, 3D, 4D and beyond). However, your point about realities and the equivalence of planes is also valid. If we imagine a 2D universe as a plane, and we combine an infinite number of such 2D planes, they would together form a 3D object - it's like stacking sheets of paper. Similarly, our 3D world could be part of a 4D world, with an infinite number of 3D "sheets" combined.
Unfortunately, I don't usually write about science, even though it's a subject I'm passionate about. I often have very little time, so I write on Medium mainly as a hobby, focusing on helping novice data scientists learn. Many of my readers are beginner developers who face challenges in finding jobs or understanding modern materials. My articles aim to address these issues, and some readers have even found jobs or started their own startups with my help. I can't say that I could write scientific articles that would be as helpful.
My expertise is more in AI and software development, where I have hands-on experience. In contrast, my understanding of physics, while deep in some areas, is still evolving. For example, when I was younger, I thought I understood the basics of quantum physics concepts from popular science books. But studying it at university revealed how little I actually knew and understood; not only were most of the concepts completely different from how I understood them, but many popular science books got a lot of things wrong. Who knows, maybe my current understanding is wrong too.
The more science advances, the harder it becomes to fully understand the cutting edge, making it difficult for new generations to claim to "understand" complex topics. At the same time, many concepts often change completely as research progresses. The simplest example is gravity - in schools I still often see teachers explaining that objects fall because of force of gravity. But if we look at modern theories, gravity isn't a force at all - it's a curvature of space-time. You can still use the law 'F=mg' to describe the position of a falling object, but the explanation behind it is completely different.
If you decide to write an article on any of the topics we've discussed, feel free to use any of my texts - I'd be delighted! Let me know if I can help in any way. I would also recommend that you submit your articles to some of the larger media publications in the fields of physics and pop science. Your articles are very well written and deserve more exposure. Publishing through larger publications could help you reach a wider audience and gain more readers. I often submit my articles to big technology and AI publications, it helps me a lot.
Another interesting concept related to the topics we are discussing is the Shooter & Farmer hypothesis from "The Three Body Problem". It's just science fiction, but the idea behind it is fascinating - take a look if you have time!
