A question about time travel

[Nuke_em_05]

My take on time-travel has always been a stance of permanence. One universe, one timeline.

Kind-of like Like Slaughterhouse 5, Deja Vu, Premonition, or (I'm told...) the Time-Traveler's Wife. You can't change the timeline, because your travels are already part of it.

Think Harry Potter (III?); Harry is saved by his own Petronus before he goes back in time to save himself.

All the time travel that will happen, has happened. Everyone from the future who time-traveled to the circa-1940s (to do what you must do with such power) already did; and obviously failed, for one reason or the other.

So, if you meet your future self; at some point in the future, you are going to travel into the past and meet yourself.

It's not some cosmic timeline-preserving force or anything, just simply that cause and effect endures, and already includes the effects of time-travel.

I thought some models of wormholes were shown to be the best shot at time travel, since they loop back to themselves you tend thru science stuff to come out of it before you left.

course most wormholes are microscopic also and while pulling one open to squeeze something through is technically possible it takes heaps of amounts of energy. way beyond anything we got going on now.

I tend to think of space/time as flexible with branches of timelines flowing out, where tiny changes make tiny bumps in the map maybe and major ones create entire new branches. So in a temporal sense each and every possibility might play out over a multitude of sister timelines/dimensions.

Sort of the sliders take on time and space i guess .
