Is it possible to travel at C in two directions ?

[Morepower (Craig)]

I'm not sure why i even want to know the answer, just thought something wieird may happen. So if you were to accelarate as close to C as possible, then spun the ship on it's axis with thrusters so you are facing 90deg to your direction of travel and accelarated again to close to C would you be traviling in 2 different dirrections at C, or as close to ? What would you observe out the window ? Sorry for the weird question, was just thinking about it.

-No

What would you observe out the window ?

-You would observe a change in direction.

If you are trying to break the rules then think of sending two ships off at 90 degrees to each other each travelling close to C. Even though the relative speed of the ships to each other from the person at the point of departure is greater than c, the two ships will still only ever see the other ship disappering off into the distance at a speed lower than C.

Spacetime bends - and what is 30 minutes for one observer is in reality 20 minutes for another. Time is NOT constant. We see this on sattelites that rotate around the earth where time passes more slowly compared to time on earth.
