Well, my brother for one. Yale PhD, 80% DOD work, dissertation on superconductivity, holds clearances he can’t tell me about.

Well, I've got news for you. If your brother is a Yale physicist and believes that theory which I doubt he either is or does, he's a quack. Here's the explanation:

According to Jasper Graham-Jones, an associate professor of mechanical and marine engineering at Plymouth University, in the United Kingdom, the claim is "totally false".

For a start, the water temperature around the Titanic is around 4 degrees Celsius [around 39 degrees Fahrenheit], which acts as a cooling effect," Graham-Jones told Newsweek.

The collapse of the composite or metal structure would just produce theoretical heat energy due to friction, but this is very low and would not be visible or measurable with the mass of cold water around it.
