Answer 1:
Distance is just the space (physical space)
that separates any two points. Time is a
bit more complicated, and many people still argue
about what time is and why it only goes forward.
However, both distance and time are measures of a
difference between two states (an initial state,
where it begins, and a final state, where it
ends). For example, you can consider two
points in space (different places), and look at
the distance between them (it is 2 miles between
my home and work), or you can consider two points
in time (different events), and look at the time
that separates them (it has been 6 hours since I
left home). Their similarity isn't totally
by chance, and you may have heard of the theory of
relativity, which showed that space and time are
related in strange and unexpected ways!
