The equations in the paper are surprisingly simple.
This usually triggers a crackpot warning in my brain, especially when the topic relates to a grand unifying theory between quantum mechanics and general relativity. That's because crackpots usually have a low understanding of the advanced math. At the same time, crackpots never pass the peer review process. The researchers look legit too. So this is interesting.
This is not my field of expertise, so I'll be interested to see what happens...
