    I would imagine that the relative motion between the entry/exit portal would be more important than the absolute motion of the two portals.

      Portal 2 ends with you (Chell) placing a entry portal on Earth vs an exit portal on the Moon.

      That means the portals were ~2236 mph (aka Mach3) relative to each other.

        Hmm well if an object passed through that portal and it wasn’t moving ~2236mph relative to the surface of the moon, then I guess the question from the OP has been answered already haha.

        Wouldn’t that provoke all air in the Earth to get sucked to the Moon due to the difference in atmospheric pressure?

          Vacuum doesn’t suck. The atmosphere on Earth would push air through the portal with a pressure of about 1 bar.
