In the original series of Star Trek , in episode " S1:E11 " The Corbomite Maneuver " . Kirk goes into a " right angle torus " to get out of the tracter beam , holding the Enterprise . My question is , how do we visualize this , right angle torus ? What is the ship doing , physically ? In space . I thought that Star Trek was liner , two dimensional . Because visually it never went up or down , three dimensionally . But listening more closely the ship moved in three dimensional space . Interesting .
