The idea of time travel is connected to the idea of the time being a container.
In my thinking however time is an abstraction and not a container. Properly speaking, what is there are things which change, and our awareness of their changes and our abstracting the specific states of those things as being before and after one another. For example when an object is moving, we can become aware of the movement, and from that movement we can abstract the positions that the object had and that it has now. The thing there is not something which exist as time-slice. We could say that it transcends the change, or so to say – it is the thing that changes, that moves, and so on.
But when things (as changing things, but there is no reason to add this adjective – i.e. changing, as there are no unchanging thing, to be a thing is to be changing, and really any change requires something that changes, some identity which transcends time) are thus seen as more actual than their states which are merely abstractions, the idea of time travel is shown as non-sensible.
Namely if the things are what is actual (or more actual), and time what is abstract, there is no way to go to the past, as the states exists only as abstractions of what is actual, and that they are not actual themselves. What is true are the things, their states are transitory (Of course the things are transitory too, but that is topic for some other post).
The only way something might feel like time-travel is to make things change towards the states they had before, (If that is possible. I’m skeptical that this is metaphysically possible too). Notice that again, this will be normal before/after changes, just that the nature of the changes will be different. Properly speaking this will not be “travel in time” but only affecting how the things change. Of course to have this illusion of “time travel” would also require for the time-traveler to be isolated and for him the changes to continue in same direction.
