When dealing with OP's scenario, only one portal is moving. permalink fedilink source parent [–] zerodawn@leaf.dance 4 points 3 weeks ago wikipedia.org/wiki/Steamboat_Bill,_Jr. Nearly a century ago. Fun fact, this movie inspired Steamboat Willie, the very first appearance of Micky Mouse. permalink fedilink source parent [–] min@lemmy.sdf.org 1 point 3 weeks ago (1 child) The problem with this analogy is that both sides of the window are at the same point in space so there is no pressure differential. What if the blue portal was at the bottom of the Mariana's Trench? What force displaces the water to place the cube on the other side? permalink fedilink source parent hideshow 2 child comments replies: [–] surewhynotlem@lemmy.world 2 points 3 weeks ago (1 child) It wouldn't. Same as if the other side of the portal was a brick wall.

If the blue portal was deep under water, the pressure would force the water out the orange portal. permalink fedilink source parent
