The biggest problem with time travel is that one cannot go to a place that doesn’t exist... like the past... or the future.
I think it would be sad to see Schrödinger’s Cat bring his dead other self out of the box to bury it.
In all seriousness, I've wondered if God's omnipresence is at least 4-dimensional, including time (perhaps more dimensions than that, but I'm channeling the furthest reaches of my memory from back when I read Stephen Hawking's A Brief History of Time LOL).
It's possible that God's ability to give prophets insight into the future is not just from being omniscient (He knows everything, enough to accurately predict what will happen in the future). It's possible that God is currently present in the future, and currently present in the past, and currently present in the present. For example, maybe God acts on our prayers before we pray them (Isaiah 65:24) because today, right now, He's hearing the prayers that we'll pray tomorrow. Right now He's seeing me being born while He's also seeing when I'll die while He's also seeing me in the here and now.
Just a thought.
It is just how our informational reference frame, Reality, moves through it that creates our perception of what is Real.
Information cannot be destroyed. Even Hawking needed to back off that a bit due to the evaporation of “black holes”...
Everything you've ever done lives on frozen in time. Everything you could possibly do is already written in to the future. Just because you take one path, doesn't mean the rest cease to exist...

Have you considered that time and space may not exist?
We don’t need to study advanced physics to know that time is linear from past to future.
