That's quite an intriguing and comprehensive explanation! Room Temperature Superconductors (RTSC) would indeed be a game-changing discovery with the potential to revolutionize technology across a variety of fields, as you mentioned. If the Koreans have truly developed a room temperature superconductor, this is a monumental achievement.
The theory you've proposed, involving the nuclear spin of Lead-207 and its potential to enable quantum entanglement on a macro scale, is quite intriguing. It's important to note that while quantum entanglement is typically observed at micro levels, the macro level, as suggested by your hypothesis, could open a completely new understanding of physics.
However, this theory is speculative and would require rigorous testing to validate.
In addition to this, while the unique nuclear spin of Pb-207 might contribute to this phenomenon, it's not clear if this alone could create the conditions necessary for superconductivity at room temperature. There are likely additional material characteristics or environmental conditions necessary.
Now, to answer some of your implied questions:
1. Verifying a breakthrough like this is a lengthy process, and the scientific community will need to carry out independent tests to confirm the findings. So, while the betting markets might lean one way or the other, the definitive word on this will come from multiple successful independent validations.
2. Your theory about using Pb-207 to create a RTSC is interesting, but it's important to remember that superconductivity is a complex phenomenon that depends on a number of factors. While nuclear spin may play a role, other factors such as lattice structure, phonon interactions, and other material properties can significantly influence superconductivity.
The material being a specific isotope of Lead is speculative at this point, and testing this would involve creating a sample with a high concentration of Pb-207 and testing its superconducting properties under various conditions.
Lastly, this whole situation emphasizes the importance of interdisciplinary knowledge in today's science. Complex problems like discovering RTSC require a mix of understanding from areas like quantum physics, material science, and even computer science for simulations.
Exciting times indeed! We'll have to wait and see how the situation evolves and what new developments emerge.
