Why Time Travel is Impossible

[Zinjanthropos]

A Christ Paradox? Forget the grandfather because there’s no way according to this one Christian POV. No one’s going back in time to rob God of the opportunity to kill his son, apparently. I found this commentary contained more unverified facts/claims than just time travel being impossible.

Theology of Time Travel is an interesting way to put it.

To go back in time and do things differently would necessitate a change in God’s actions or reactions to those past events, thus changing God’s unchangeable nature. This is impossible. God is immutable.

[...] To be eternal does not mean that God is unchangeable from moment to moment. Created things experience time as a succession of moments one after another. However, God is apart from and is outside of time. He does not experience a succession of moments as we do. All points in time are the same to God. Because God experiences life in this way any decision made is made in his eternal nature. It is made once and does not need to be made again, his decisions are eternal. Doing so would necessitate a change in his eternality.

Time travel would imply that the life of Jesus would not be fixed and thus man would have the power to thwart God’s plan for Jesus and for our salvation.

To use a popular concept from science fiction, the conception, birth, life, death, and resurrection of Jesus are “fixed” events in history that cannot be changed. In fact, all events in history are fixed and cannot be changed since there was a succession of events from creation until Jesus that were necessary to take place resulting in the coming of Jesus.

Any time travel that actually contributed to or caused a past event that the future is dependent upon would be allowed. (Some arguably lame research conducted over a decade ago suggested the process might actually be selective like that, forbidding only travel that made alterations in the past inconsistent with the present and future.)

On the wild side, never underestimate what originally "natural" gods descended from the inventions of inferior creatures could discover, tweak, and accomplish. An archailect of the distant future -- itself the product of a billion years of self-engineering or technological evolution, with a vigintillion microbots and macrobots under its command, might circularly trigger cosmic inflation, Big Bang, etc. In this category of "speculative theology", it could eventually escape the boundaries of time/space, configuring its being in some medium prior in rank to such (pregeometry), qualifying as outside the "creation" that reciprocally created it.

Nice to know they admit that event "Fixing" was on their timetable, so much for free-will from a theological perspective.

Truth be told if we could go back and change things, we'd create a Maelstrom.

Think of it a bit like a Droste effect where every iteration just has to go out of it's way to do something more "free-willed" than the last, it would just pure chaos, shape-shifting turtles all the way down.

And they say God is timeless, he exists not of time. Yet he can invent it and call each phase of creation a day, even though he personally took no time doing it. All very convenient, other than being supreme being he’s pretty much immune from controversial timing problems. He’s like a photon in some respects.

I’m going to assume that timeless god can’t go back in time because if he could then time travel is possible. Back in time not something this article endorses.
