Cant imagine a solution to it either. Perhaps that means I'm not imaginative enough!
I think it would work if you imagined parallel universes. Lets say all these parallel universes existed outside of time (time didn't exist) and what we perceive as time is just the 'selecting' of a given frame. Time travel would then be simply selected a frame where your Delorean just happens to exist with you in it and the world around you just happens to look and be like 1955.
There would be another alternative where you literally had to have a teleportation booth already existing that kept a vacuum for you to teleport into. I'm not sure how the quantum vacuum fluctuation would fit into that. I think this is an interesting idea because it explains why we don't actually see time travelers visiting. It's because we haven't invented the booth yet, sort of like Alexander Graham Bell not being able to make a phone call until someone else had a telephone.
How does water travel through time and space as it traverses 4 co-ordinates of spacetime at t,x,y, z to 4 other different values of t,x,y and z ?
Whatever values we depict in the frame of reference, one thing tends to happen, takes the path of least resistance. Even lightening does the same in physical nature. If we can time travel in the way you wanted, path of least resistance will be part of that. However to start with our bias of looking at such a task through space bias or time bias needs to be addressed. That is not easy the way we are used to thinking of travelling in general. We tend to think of going from point A to point B and forget point A has 4 co-ordinates in spacetime and point B also has 4 co-ordinates.

Do you consider time travel to be traveling through every intermediate time from your origin to your destination?

This makes lots of sense to me.

So to paraphrase, you're saying that if I were to time travel back to 2010 to see the pies win the flag again, I would need to travel "through" 2016,2015,2014....all the way back to 2010, and not "jump" those years back to my desired location?
Nope. I'm not saying that.
Also in the movie Terminator there is a ball of energy that pushes/destroys any existing material out of the way even solid objects.
Does time ever stand still, so to speak ?
How in reality, do we not traverse time ?
We do travel through time and can adjust our speed through time relative to other observers (relativity). I was asking if you viewed time travel only in terms of moving through a continuous set of points. Your answer to BustedWing answers that.
Time standing still would be an interesting one, it's possible that it actually happens and that we don't notice it because we ourselves are still like the world around us. Almost like finishing a chapter of a book and putting it down for the night, the characters in our book do not notice. Stopping time whilst being able to act and have a personal sense of a flow of time is a mind blow.
It should be noted, speed is a scalar, not a vector.
In relativity we only adjust our 'speed' through time not the direction we move in it.

Ok. So what are you saying?

BTW - interesting discussion! A rarity on bigfooty.
If you think about it seriously (hey - it's time-travel - it can't be serious!), the 'space' issue is insurmountable. The earth is moving around the sun all the time, so if we go back in time WITHOUT moving in space, we probably won't even wind up on the surface of the earth. Then the entire galaxy is rotating, not to mention the expansion of the universe (galaxies moving relative to each other), and you can immediately see the difficulties.
While I believe some 'time-travel' effects are possible at the sub-atomic level, the idea of time-travel as portrayed in SF is ludicrous.

As people get more into possible practicalities of time travel, my conjecture that it will be far far easier to transfer information or even drones across time than fragile humans becomes clear
Once you can transfer information across time, you then no monger have to wait for technology advances, that info can be sent back to you
That in itself has all sorts of implications, build the first receiver and you then commercially own all new technology

It did in school, especially when Miss Broughton was droning on and on.
To answer the question, no time doesn't stand still , it is continually moving forward. It is the perspective of time that changes e.g my example above.

By the nature of it, you decided to go there after you had already been there. The space you occupy was already occupied by you from that moment, because while it was before you went there it was after you arrived there. You are merely fulfilling your own destiny.
Unless, of course, you kill your own parents before you are born. In which case the location destined to have you does not ever get you. Suddenly the air has to move into that space. All the missing time travellers that killed/will kill/are killing their own parents and therefore were/will be/are wiped from historyfuture (or willon onthen according to Douglas Adams) is where wind comes from. The air is moving to compensate for where it shouldn't need to be. One of these time travellers presumably will arrive/has arrived with a butterfly from Brazil.
Only when God blows time on.
Time stands still if travelling at the speed of light. Which sort of negates the very essence of what speed is. Except for the drug. And you need to be on drugs to understand relativity - or quantum theory.
The things I wanted to do to Miss Broughton!
Preserving your health and living beyond your time you consciously believe you at in now, longer than your peers. Is fake time travel, whatever means you use. And probably serves no useful purpose
Interesting where the thoughts went.
I think we are all still coming to grips with the whole idea of spacetime as one, in our present generations of human history. Love how it messes with our minds, in a good way.

Watching Predestination on SBS2 and I was sitting there thinking I know this story from somewhere. On another forum the question was asked if you could time travel would you go back and warn a relative from a bad decision or an accidental death etc. And somebody posted this short story by Heinlen ''An Unmarried Mother''. 9 pages long but wow.
