The portal moves towards the people. It’s a hole. Momentum won’t transfer from nothing as the hole is the one moving.

Because the portal is moving them through it
Like how you would move through a hoop if it passed through you, it’s just a door through space

Do we agree that the massive block with the blue portal is not moving? So, imagine we are standing right in front of it when it happens - what happens exactly? How do the people appear?
