I wrote in the above post about the PHYSICAL information and physical laws. Your argument about radar guns is not about PHYSICS; For example, the uncertainty principle is a physical information but not guns, cars, ships and so on - It's about technology.
Your essay use generally known physics information that was NOT created by you. Therefore it is true that the essay contain physical information copied from the textbooks and Internet. I understand that really you learned all this information at the University and then you prepared your essay using your memory. However, it is the same - your essay contains GENERALLY KNOWN PHYSICAL INFORMATION copied from external sources.
For example, infnitesimal changes, parabolic functions, Zeno's paradox, Doppler effect, Spekkens' epistemic interpretation of quantum mechanics - it is generally known information copied from textbooks. If you comments about quantum mechanics and SR it does not means that it is YOUR information: ''Quantum field theory combines quantum mechanics with special relativity and so technically deals with a at (Euclidean) spacetime". You are NOT the creator of this physical information. The essays filled with such information and authors commentaries is not original and contains information copied from general sources as textbooks, papers, Internet and so on.
Please show me the PHYSICAL information created by YOU in your essay.
Also, I don't see any proofs in your essay that the Universe is digital or analog. The discussions about radar guns prove nothing about reality.
