  • But the object doesn’t enter at speed here it’s stationary. If a hoop is thrown at an object and passes around the object the object is still stationary. The speed of the portal relative to the object does not impart movement on the object.

    The quicker the portal moves the quicker the object appears on the other side but for the object to shoot out it means energy is being transfered from the car to the object.

    If you’re right then what happens If the two portals are moving at equal and opposite speeds?


  • I think it’s A because I assume a portal stitches two points in space to each other.

    So if I have a surface A and B with a portal ‘]’ in the middle A0 A1 ] A2 A3. B0 B1 [ B2 B3

    A portal creates a new surface

    A0 A1 ][ B2 B3

    And if you move the portal the new surface changes.

    A0 A1 A2 ][ B3

    Speed is distance over time. When a portal moves the object that passed through the portal stays stationary. Let’s say I am standing on B2. When the portal advances I find myself standing on A2 , have i moved? No the environment has changed but i am still in the same relative position with respect to the portal surface. No distance travelled so no speed.
