Yeah, but the traveller is still subject to time dilation. In the oft-mentioned example of a twin on a spaceship, the twin on the spaceship will have aged less no matter what sort of trip they take.No. If you start on the surface of earth, then travel at 50% the speed of light away for X time, due to the stretching of time-space it looks (from earth) like it takes longer. From your perspective, it looks like time on earth takes longer too.
If you then slow down, turn around and head back, time on your ship and earth appear to speed up, and by the time you land back on earth it all catches up and time has passed normally for both you and observers on earth. From what I remember years ago when I learned this, the twin paradox can never actually happen. When you return, observed time-space catches back up.
Relativistic math is for compensating for appearance from light speed observations, it doesn't actually create more time out of nothing.
Edit: I think I may have confused the point you were making. Regardless of the details of the scenario, anyone moving at high velocity will be subject to proportional time dilation, which is directly relevant when dealing with superfast people (as per the original comment). By my understanding, the twin paradox deals with why, when it appears to the traveller that the earth is slowed down, when they return home only the traveller has experienced significant dilation. This is much less relevant when talking about, for instance, someone running in a 2-meter wide circle at .9c.
