## Main Question or Discussion Point

I have seen in SR that regular time and regular distance is equal to slower time and less distance because of length contraction.

Say a person on earth sees a ship moving towards it. This reference frame has regular time and regular length and it views the ship's reference frame as having slower time and less distance because the ship sees everything moving so the distance is contacted.

My issue with this is that for the ship's reference frame, it is the opposite. The ship's reference frame has regular time and less distance because it sees everything moving so distance is contracted and it views the earth's reference frame as having slower time and regular distance.

So what is the point of converging time and distance for the earth reference frame when for the ship it is the exact opposite?
