I don't think the differentiation between parallel universes and time travel in 'Groundhog Day' is ridiculous. I believe I can disprove time travel, but have no such grasp of parallel universes, so that's an entirely different physical mechanism, and more believable for me.

However, a caveat to this is I also believe I have experienced information being sent back in time, albeit not in a physical form, but as thoughts, which may well have quantum aspects that quite complicate my beliefs about the impossibility of traveling back in time, which is a classical hypothesis.

It's an interesting topic for a fiction work, as you are well aware, LOL.

Thanks!

Yeah, I remember reading something about retro causality - where they say, that information from the future can be exchanged with the past - that is interesting. About my novel - yes, it is a very interesting topic - I will post the audio version her on Hive next week, so you can have a listen!

Thanks!
