say your at point a, you set out to go to point b, in between you there is a vacuum. why does it take time to get to point b? if there is nothing between two points than there is nothing to cross, right? why does it take time and energy to pass through nothing?
a--------------------------b

let me put this another way, here's a and b
a--------------b,
here's c and d
c---------------------------d
if you use a certain amount of energy to get from a to b, it takes you 5 minutes. you use the same amount of energy to get from c to d, it takes you 15 minutes. why does it take so time to travel through nothing? you're already superimposed on your destination before you even leave if there's nothing between you right? and if there is something between you what would it be?

what a retarded question
it takes no energy to cross if you´re already moving and nothing is slowing you. it takes energy to accelerate in any direction.
the other point is just retarded.
what´s between you? space...

Of course there is something inbetween the two points: vacuum.
Vacuum is neither empty not is it trivial. It is filled with fields and
has temperature, velocity and curvature. Right now I am holding
two Samarium-Cobalt magnets in my hands. They are so strong that
I can even push them together and yet, there is nothing between them
than "vacuum". Except for an enormous number of photons mediating
the magnetic force, that is.
The reason why it takes time to get from A to B is that all of nature
is local. It takes no time to get from one point infinitesimally close to another,
but to move a finite distance you have to move an infinite number of points.
The result is a finite speed of light.
As of today nobody has managed to successfully construct a non-local
field theory which does not suffer from catastrophic problems. It seems,
neither has nature.

Modern physics cannot truly explain what time is or if it even exists for that matter, but let me just put it this way.
Take the planet earth for example it is travelling through space around the sun.... wouldn't you agree. The space it is traveling through is a vacuum right....? How long does it take the earth to orbit the sun... one year right?

No but to travel , you can not have a speed higher than light speed. It is sure (Einstain proved this). So you must take some time to traval even in absence of any interaction

yes.Time us invariable and no one can escape it but
in other dimentions(not yet discovered but possibility ) nothing could br said
