Physicist Dr. Michio Kaku discusses time travel as a real possibility in the link below although I believe that the USS Eldridge did not time travel during the PX.  Still in all, it is an intriguing concept and I personally cannot disprove any time travel claims related to the PX.

Yes, it's an interesting idea, but of course it lacks proof-of-concept

Have his book "Hyperspace" on my bookshelf. And I agree with you, that
time traveling did not occur at the PX, despite Al Bielek and some
other folks stated so - but we know what to think of them, don't we ?
