I'm not a materials scientist but an electronics guy.

> 1b) shows the resistivity at some unknown temperature. They are applying current and measuring no potential drop. Just what? First, state the temperature, next measure it as a function of temperature. At the critical temperature the resistance drops to zero. All they have shown is that the contact inputting the current is probably disconnected…

this does not pass the sniff test for me. I explained on reddit myself why I think it doesn't make sense.

The only way that could work is if they just straight up fabricated everything, and in that case all bets are off.

I can't comment about the others since I don't know enough about it. Considering 1b) makes no sense with a modicum of knowledge, I really doubt the veracity of the rest.
