>Either side of the portal is the same frame of reference. which is the most retarded take and makes no sense lol. that is not consistent with how portals work. imagine you jump on a portal that's on the floor, from a heigth, and the other portal is on a vertical wall. you gather speed from falling and when you pass through the portal you'd suddenly stop instead of carrying the momentum. that is not what is happening in the game. at all. also no matter how much you screech you cannot talk about "the same frame of reference" since the moving portal changes that equation being an Atodd is the weakest position ngl
