That's half right. You can't travel to the event e_2 with
coordinates (x=0,y=0,z=0,t=0) starting at the event e_1 with
coordinates (x=0,y=0,z=0,t=2005). The displacement vector
from e_1 to e_2 is (0,0,0,-2005), and there is no physical
way to travel with that displacement.
>I'd like to see you raise your hand WITHOUT adding vectors.
You are deeply confused. Vector addition is not travel, it's
a mathematical operation. Travel can be *described* using
vectors, but not all vectors describe travel.
