>I have to congratulate you. It's an impressive feat to write that many words despite all the mental disabilities you have. I'm surprised you could even breathe for long enough to write that retarded post.
I knew you'd get angry, you've been hostile this whole time. I've seen people get angry over some stupid shit but this pretty funny.
>Not a fucking factor. In neither >>168354 nor >>168338 is perpetual motion a concern, it's just redirecting energy not fucking creating it.
Perpetual motion is a "fucking factor." In Portal if you put two portals on the floor and jump in one, you oscillate between the two forever. This is perpetual motion, and is not possible in the real world due to conservation of energy.
>Have you ever fucking seen a pendulum before in your pathetic life? >>168354 would not result in the cube just "standing still" under any circumstance outside your retarded imagination.
I have seen one in my "pathetic life," and it proves my point. In real life, friction applies, and pendulums don't move forever once acted upon. If you have a pendulum, it will be still until acted upon, after which it will return back to being still until it is acted upon again. Its reaches a state of equilibrium, which is being still. Thank you for giving me another good example to help my argument.
>The hole would allow the cube to "fall" relative to its position and the momentum would keep it going up the other portal, albeit not entirely, and it would keep going back and forth, losing a little bit of momentum every time, until it eventually settles with exactly half of the weight out of each portal.
Thanks for understanding what I was saying about perpetual motion and equilibrium. You're doing great bro, perpetual motion isn't real. Keep it up.
>Again, in universe (and independent of source engine retardation) the portal on the moon maintains the logic of portals that are still relative to each other DESPITE the moon being moving relative to earth and therefore the portals being moving relative to one another.
It's a cutscene that you could (maybe) argue is in line with the X and Y axis movement in the neurotoxin puzzle, or just Valve's recognition that none of this makes sense, considering a game where flying objects have no friction has a cutscene of objects being sucked into the vacuum of space. Why? Because it's a video game, the entire concept you've been playing the whole time hasn't made any sense and you have accepted that, so they just expect you to accept the Moon thing so that they can have a dramatic and impactful ending. This scripted cutscene isn't actually following the rules of the interactive puzzles featured in the video game.
>All motion is fucking relative and this stands true for portals.
This is not the argument you think it is. You’re applying physics improperly. All this means is that the surface with the portal moving toward the surface with the cube is enacting the same force as if the surface with the cube was moving toward the surface with portal, if both surfaces have the same mass and in both examples they were moving at the same velocity. It means that if they collide, they would both move opposite of each other with equal velocity. It doesn't mean that the portal would transfer all of its kinetic energy to the cube. In fact it seems far more likely the portal, considering it is completely stuck to the surface it's on, would transfer its kinetic energy to the platform the cube is on, not the cube. You haven't argued why Valve would make the portal transfer its energy to the cube. I'll even argue why Valve might choose to implement it the other way. Imagine you have a puzzle where you put a portal on a moving piston, so the portal is now moving on its Z axis toward you, and then you use a jump pad and try to launch yourself into the portal at the right time. You hit the jump pad and you're now flying at a speed of 2 toward the portal, and again, the portal on the piston is moving at a speed of 1 toward you. If B is "correct" as you say, once you pass through the portal you are now moving at a speed of 3. In order to perfectly preserve kinetic energy the portal would have to stop moving. If the portal kept moving with a speed of 1 but now you have increased from a speed of 2 to a speed of 3, you have just created kinetic energy out of nowhere. Sure, this is totally possible to do with code, and A is totally possible to do as well. I have no reason to believe Valve would choose to implement it the B way, or at the very least, just as much reason to believe it as I have reason to believe A. Source calculates the kinetic energy of objects and these objects preserve energy perfectly to a point that you can make perpetual motion in Portal as we previously agreed on. So it is entirely possible to deduce that if the object (you) is moving at 2, and they'd just keep it at 2 like the game's code is already doing. The portal, another object, is moving at 1, so it's entirely possible Valve would just keep it at 1. In the picture with the cube sitting still on the platform, this would mean the cube is moving at 0, so keep it at 0. You're saying you're sure they would implement it in a way where B happens and all of the kinetic energy of the portal is transferred to the cube in the opposite direction, and I'm saying you can't know that unless you actually give an argument as to why Valve would do it that way. There's no telling what Valve would pull out of their ass in this situation, but this hasn't stopped you from declaring one of the answers as being "right" and getting so angry that your post turns into comedy.
>You're fucking retarded.
>Go suck a barrel of cocks.
The fact that this angers you is really funny to me, please write another angry diatribe.
