Speed is a relative property of an object and a reference frame (i.e. another object, like e.g. a planet) permalink fedilink source parent hideshow 2 child comments replies: [–] SirActionSack@aussie.zone 1 point 3 weeks ago In this particular case it is speed with respect to the fixed reference frame of the game. permalink fedilink source parent [–] Nalivai@lemmy.world 1 point 3 weeks ago (2 children) To the space outside of the blue portal. Moving the orange portal doesn't drag the whole surroundings, so assuming both places are on the same planet, the momentum of the box in relations to both places is the same permalink fedilink source parent hideshow 4 child comments replies: [–] flying_sheep@lemmy.ml 1 point 3 weeks ago (1 child) As Optozorax taught us, gravity must act through the portal. permalink fedilink source parent hideshow 2 child comments replies: [–] Nalivai@lemmy.world 1 point 3 weeks ago (2 children) Well, it doesn't in the only source of knowledge we have: the game Portal. I don't know enough about gravitational forces to have a coherent theory on it, gravitational waves moving through space-time is a bit beyound my real understanding. But in the game if you put a portal on a ceiling, it doesn't "suck" you until you're throuth it, so there it isolates gravity somehow. permalink fedilink source parent hideshow 4 child comments replies: [–] mkwt@lemmy.world 2 points 3 weeks ago If you stick to the premise that the portals exist in a universe with GR, then we can pay much know that space-time is locally flat in and around at least the middle parts of the portal. We know this because things don't get fucked up when they're going through. permalink fedilink source parent [–] flying_sheep@lemmy.ml 2 points 3 weeks ago At this point, I consider Optozorax’ research the primary source of how portals work. If the games disagree, they're wrong. permalink fedilink source parent [–] Snazz@lemmy.world 1 point 3 weeks ago Moving the orange portal kinda does ‘drag the whole surroundings’. It moves an entire universe. The cube is stationary relative to the universe of the platform it’s on, but it has momentum relative to the universe through the portal. The question is which universe is the cube in? What is the boundary of the portal surface? permalink fedilink source parent
