Noone really knows what an electric field is

Click For Summary
The discussion centers on the fundamental understanding of electric fields and the nature of charge interactions, with participants expressing skepticism about the current explanations provided by quantum electrodynamics (QED). One participant questions how charges can repel each other without a mediating material, suggesting that an exchange of photons could explain this phenomenon, but remains puzzled about the underlying causes. Others emphasize the importance of mathematical understanding in physics, arguing that analogies can be misleading and that a deeper grasp of QED is necessary to comprehend electric fields fully. The conversation also touches on the philosophical implications of scientific theories, with some asserting that while QED is a robust model, it does not provide absolute certainty. Ultimately, the thread highlights the complexity of understanding electric fields and the ongoing debate about the nature of scientific knowledge.

Which theories in physics have been "proven to be a set of facts?"

Never, and that's my point. When the original poster inquired about "the cause of the cause" to understand what something "really" "is", I think the correct answer to his question would be that science isn't about reaching a finality about what something "really" "is". Science isn't about Kant's "the thing in itself." Science is about finding patterns that correlate measureables with other measureables, in a way that has been found to provide predictive power. Science continues to accumulate, and never completes the search for "the cause of the cause". But that's not what the other people replied to him. Instead, they replied to him that OTHER people HAVE reached the final understanding, and that only HE hasn't learned about it yet, that HE hasn't read the right book.

Wow. Sorry gents for opening a pandoras box. I am merely maintaining that I and possibly others can obtain a better understanding of say...Maxwell's equations is they could be set to analogies. I firmly maintain that still. So, I was challenging the brains on this forum to come down to my level and to the best of their ability create analogies that can better explain the fundamentals than just knowing the formulae. A perfect example.
Del dot B=0
To you guys, you see this and think "Oh, there are no magentic monopoles." But to me that just double the questions I have. So what does it mean that there are no manetic monopoles and how does this statement relate to the equation. Now if an analogist with proper abilities could come along and say something like...

Del dot B=0 is like a belt with no seam. It has no beginning (source) or end (sink) it's divergence is 0, given that divergence related to sink and source. (not even sure this is correct but it still a point I'm making).

Then I could look at the equation and think of the analogy and it would help reinforce my understanding, memorization, ease of explaining it to others in a non-mathematical way, and possibly understanding similar equations, based on remembering my analogy.
