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.

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

[–] Serdan@lemm.ee 4 points 11 months ago

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

Yes, but the flow rate is only so much. It was only open for a short time before Glados closed it.

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.
