What I did not know is that because hydrogen has various isotopes such as deuterium (D) and tritium (T), some rarer forms of water exist. In addition to ordinary water (H2O), you can have semi-heavy water (HDO), heavy water aka deuterized water (D2O) and super heavy water aka tritiated water (T2O). Tritiated water is radioactive.

There’s also HTO and DTO (https://en.wikipedia.org/wiki/Isotopologue) and Oxygen has 3 stable and 13 unstable isotopes (https://en.wikipedia.org/wiki/Isotopes_of_oxygen), so many more variations exist.

> inflation necessarily predates big bang A tangent, but how can anything pre -date the big bang? Time itself is supposed to have been created at that point. Did you mean inflation necessarily follows a big bang?

> Time itself is supposed to have been created at that point Our space-time began at the big bang. Even decades ago, Stephen Hawking was talking about it like "Since events before the big bang can have no observational consequences, we might as well leave them out of our discussion and simply say that time began at the big bang."

>> events before the big bang can have no observational consequences

There are people working to disprove this. There is a concept floating around that the CMB might contain evidence of something from before the BB. If our universe came into existence within some other universe, then arrangements of large gravitational objects in that universe may have some impact on the early formation of our 'pocket' universe.

I think GP was referring to Montagnier's support of the water memory theory (a fraudulent theory made up to support homeopathy), rather than his comments on covid 19.

This makes me wonder if that team discovered HIV despite his contributions, not because of them.

> What could we not know about water? It’s wet! It’s not. Things that have water on them are wet, water is not.

Water almost always has water on it.

It’s extraordinarily rare to interact with a single H2O molecule.

Therefore, the overwhelming majority of water is wet.

The issue occurs if the new state is inherently lower energy. This is already the case with prions.

I am not under the impression folding proteins is a state-change, and it's also unclear to me if it is a chemical reaction, so I do not think I understand the relevance of this point. I specifically stated the parameters.

Both are, essentially, about crystalline structure. That sounds quite similar to a phase change to me. Especially if we consider ice to have multiple phases.

Ho, M. W. (2014). Large supramolecular water clusters caught on camera-A review. Water, 6, 1-12.

Here they show pictures supposedly in support of water structure.

Quite a bit of work in the area.

Or it is uncorrelated. I personally met a successful local technical innovation guy who believed in perpetual motion / free energy devices and told me stories about their “presentations”.
