(Ok, heres my newbie post for now. Hope this is a good discussion topic.)
Consider the nature of time itself for a moment.
Time has been said to be 'flowing' or 'were moving' through it. Of course these descriptions may not mean anything in the real world, but could it possibly be that our brains are correct in such a description?
So here is the thought:
If you were moving above a featureless surface, and you wanted to know what your direction of travel, you can mark the surface that your passing over.
You would then know your direction of travel, as it would be opposite of the stationary mark.
Now its obvious that time flows in all directions so the surface will be a sphere. instead of a one dimensional mark, lets use the sphere itself as a marker.
Now if suddenly we were to attach the surface of the sphere to a 'stationary' point in time, which way would it go?
I thought about this surface suddenly flinging off at c like a light speed balloon, but then the fact that the balloon is increasing in size is forward progression in time, although the surface would be relativistically static. So then I figured that it may instantly collapse at c into an infinitely ever collapsing singularity, getting smaller and smaller, left behind in the temporal distance was we the observers continued through time.
(Hmmm, gravity tends to run that direction as well.)
This sounds alot like balloon theory.

is not possible, here In fact anything with mass cannot even reach the speed.

Of course instant light speed is not possible with a massive object like a ship, inertia would defeat that idea, plus the fact that you cannot have mass travel at exactly the speed of light. Mass increases with speed, and will become infinite at c. Mass may travel at 99.999% of c but not 100%. Thats why this can only be a thought experiment.
These ideas are not of my own originality, but can the concept of space 'moving' or 'flowing' through a dimension of time be disproved?

Thought experiments still have to be physically viable. Your thought experiment might well be interesting if the laws of physics were different. As it is, it's not really relevant.

I'd say your all being a little harsh, keep in mind that some of Einstein's most famous thought experiments talked of moving at c. Both of Scott's experiments were rather poorly written (Sorry but they were), but you could all at least try and be a
little more positive and a little less critical...

as time is duration of events that run into space it has no direction
only objects that move into space have direction
and duration of movement of objects is time

This is the falacious argument of "proving the negative" by stating that because something cannot shown to be false it must be true.
Bzzzt! Thanks for playing.

Not sure that time "flows" in ANY direction, much less in all directions. It's obvious that we experience it as the present as we progress from the past->present-> future.
What does the Universe look like to a Photon. Traveling at the speed of light, it thinks it arrives instantly, never aging (or does it?). It experiences no distance (or does it?). Yet, it can transfer momentum to physical objects. What is proper time for a photon?
