What if the team itself did create LK-99 that is a superconductor, but they aren't able to reproduce it and only have the sample left that works. Hence, they aren't able to make more of it to prove their success, but rather decided to release the paper and method so that others can try to reproduce it. Given the amount of interest, they could put hundreds of labs to work trying to recreate what they themselves can't, hoping someone will find what they found and have an actual process for doing so?

Is that even possible?
