Lets suppose we have a flat surface that is
as far as we know infinite in length and width.

We mark a line and call it the 0 point.
we then mark lines that are 1 mile away from
this 0 point so we will have parallel lines every 1 mile.

An observer stays at the 0 point (A)
an second observer is in a spaceship (B)
traveling at at .5c and the clock that is
at the 0 point(A) starts when it (B) passes the 0 point.
According to basic math, the object will pass by
the 93,000th line in 1/2 second.
and the 186,000th line in 1 second..
(silly basic math)

so...
What time does (B) pass the line according to
the time dilation of (B) while in motion?

In return, I ask that you commit seppuku or something that garners a
similar result. When you have completed this task, I will help you
learn.
