Indeed there is. I think their approach ends up being circular yet still might prove to be practical nonetheless. It’s an interesting approach. I’ll have to work my way through their submitted paper though. Thanks for the link: Time has been one of those bits of QM that’s been tricky: Most of them time, it’s eliminated from it as much as possible or rather it’s used in the way that its used in mathematics: as a counting mechanism like 1+1=2 rather than something whose origins can be investigated and properly quantized further.
Thank you! Anything having to do with Time is up my alley.
