You'd reach it, even theoretically, you're already THERE the
moment you envision the goal.
You're conceptually in TWO places at once: One at the goal line,
the other traveling TOWARDS the goal line.
So even theoretically, just to be able to STATE the goal,
imagine it, mathematize it - you already have it and you're
already THERE.
There's no paradox.
One of the limitations of mathematics, honestly; the inability
to see itself.
