It's scenario A, there is no momentum from the cube.

>>377139280
Speed is relative, there is no difference t between the cube slamming into the portal or the portal being slammed into the cube. The cube goes through the portal at the same speed in both cases (not counting gravity).

D. Anything else is wrong.

>>377139710

Fairly sure that if I took a speedometer and measured the cube's speed as it exited the orange portal it would be greater than zero. Are you arguing that the cube has a velocity but no momentum?

How does a cube move through the portal if it can't have a velocity? An object has to be moving for it to move through a portal. If a mass has a velocity, then it has momentum.

>Bfags will argue with this

>>377143237
Ever pulled a plug out of a port? Dut the plug just split because you where transferring energy on just one side? Its energy affecting one side of an object, so the movement after that will be momentum of the box will be the original speed * the percentage of the box that's already after the portal.

I think we can all agree that portals can't exist according to the laws of physics, and this problem highlights one of the basic problems with them.

The fact that people spend so much time legitimately arguing for either side of a paradox is pretty sad.

>>377143237

Yes, suddenly accelerating half of an object would cause it to pop into the air or, if violent enough, destroy the object. This is literally what happens when you pull on anything in real life -- you are directly accelerating only a portion of the atoms. What are you trying to say?

If you think that's what I was saying you're fucking retarded. All theoretical scenarios involving portals are equally impossible. Attempting to apply real life physics to them is idiotic, because they inherently violate the laws of physics.

The only argument that has any bearing is one supported by evidence from the game. They can ONLY exist in a fictional scenario, so look to the game they exist in for your answer.

In reality there is no such thing as a conclusion, only a point where you get stuck.

>>377146803

Great, so you're saying it's perfectly valid to discuss this scenario and come to your own conclusion, contrary to what you've been shitposting over for a while now.

People aren't even arguing about portals any more, they're just arguing about arguing about portals.

>>377146708
>Happens in the game
>not cannon
Whether or not some (not all) fans denounce it does not mean that it isn't cannon. It has never been said in any audio log (correct me if I'm wrong) or in any writing that portals cannot move, and in fact the engine is programmed to allow it. So, despite the fact that portals are not typically allowed to move for gameplay reasons does not mean that they cannot move in universe.

>>377146286
As much as I enjoy the descriptions on some of the newer additions, it dilutes the point of the original and makes it less funny.

>>377146942
Not at all. I was stating that I never implied a thought experiment had to be conclusive.

As far as this one goes, any conclusion is just as invalid and baseless as the other since the system in question invalidates the principles you apply to it to form that conclusion.

>>377147608
Fuck off shill.

>>377147640
That's a whole lot of buzzwords that end up saying nothing of substance.

>>377136516
It is a.
It has always been a.
Anyone who says b is either trolling, or legitimately unsure about physics.
Also, a is only correct if we are assuming that portals can be attached to moving surfaces.
If we are not assuming that, then neither a nor b would be correct.

>>377147741
Physics is just another part of nature that is always changing. It can be either A or B at times.

>>377139186
C, without hesitation, provided they have seams running up the back.

>>377147693
The system (the portals and cube) invalidates the principles you apply to it (the fundamental laws of physics) to form a conclusion. Therefore, your conclusion is baseless and no more valid than another. Was that easier to understand for you?

>>377147741
Your shaky understanding of physics can't compete with the pure logic that dictates it must be B.

it's theoretical physics, so theoretically couldn't it be argued that both could be plausible depending on how inertia is translated through portal technology?

>>377147982
Portals don't invalidate the laws of physics. Remember, speedy thing goes in, speedy thing goes out.

>>377148086
Well the portal technology we have available today shows A as being the more logical conclusion.

>>377148023
The only way it can be b is if the floor (where the cube is resting) is rising quickly, and the piston containing the portal doesn't move.

So we're back to >>377144473 which you vehemently denied saying. It's quite clear that you could describe a model for portals to cause A and you could describe a model for portals to cause B. One of these models will be more elegant, one of these models will more greatly conform to what we know from the games, one of these models will more greatly conform to what real-life physics we -can- impose, yet you say all discussion of the matter is worthless. That people should not have fun arguing the above because all models are equally impossible (as if the participants didn't fucking know that).

>>377148157

Prove that physics is real, open up your back and give me a mound of concentrated physics. I'll be waiting.

>>377148570
Nice meme

>>377136516
Answer is A.

Portals work by bending space time and connecting to points together. The cube doesn't move through space, space moves around the cube, therefore it doesn't gain any energy and it remains still.

>>377148762
Don't reply to me.

>>377148456
They're not equally likely; they're all invalid. None of them conform to real-life physics, and arguing fictional physics is pointless. If you want to talk in terms of the game, it's not even an argument anymore. Just go into the game and show what happens.

You cannot perform the experiment in game. Mods show what the developers arbitrarily chose, but that does not necessarily co-align with what they think should actually happen (one way could have simply been easier to code, which of course they would go for when the scenario can't exist in game).

You'd have to ask the developers themselves, but even then there's no reason to believe their opinion holds any more weight than the random anon.

>>377149745

You cannot set up OP's experiment using the scripted moving portal sequences (the laser and the moon).

And I bet you $5 that the developers didn't intend for players to do that. You cannot argue canon from a player exploit, because as said before the developers just coded whatever turned out to be easier and not necessarily what behavior they think should occur.

I have a legitimate question for A-fags:

How fast does the first half of the cube exit the orange portal?
