Time Travel, True or False Options

It's depicted in several movies. Terminator uses technology, The Butterfly effect uses a phychological element, and Superman circles the earth several times to turn back a few minutes to save Lois from an earthquake. Is time travel possible? Magic, technology, speed. What are your thoughts?

twice i have been through the physical gates between the parallel worlds in the parallel dimensions (darn near killing me each time) via magickal methods, and from my experience the same time stream runs through all the parallel dimensions (just things happen differently as it is a different stream), so to manipulate time you would have to actually work in a localized field (which would revert to the normal stream once you were done)

noah (the flood dude) messes with localized time when he makes the sun go backwards on the stairsteps somewhere in the bible - you need a biblical thesaurus to understand what's going on there too as the translation is totally whacked from what it should be if you use a kjv bible

if you walk from one edge to another edge of a page in 2d, there is a time when you are on the first edge and a time when you are not there but on the other edge

if you walk from one corner to another corner of a cube in 3d, there is a time when you are on one corner and a time when you are not there but at the other corner

if you walk from one cube to another cube of a hypercube in 4d, there is a time when you are in one cube and a time when you are not there but in the other cube

and so on
