There is no future time.<quoted text>
Yes if you sit in the back facing backwards, you can count exactly how far you been.
But if you ever get to drive the ship, you will be seeing where you will get to in the future.
The past time is no more valid than the future time.
It's just a matter of perspective.
When you look from the ship to see where you will go in the future, you are looking at distance of the landscape, or seascape.
You are not looking at time. You cannot see time.
Time only quantifies the occurence of events.
It's also finite.
You are not equipped to discuss these matters.
