a or b in your country?

If someone threw a hula hoop o top of me, I wouldn't be thrown through the air so I'll go with A. I think you've used to wrong one though. From what I remember, the question is if he'll be thrown if the bottom platform goes up and not the contrary. In that case, I might go with him being thrown through the air since the platform will stop and he'll conserve momentum. Of course, if the portal were big enough for the whole platform to go through it, he'd stay on his feet.

>>215896571
Do you decelerate to absolute zero when you jump through something?

>>215896678
The portal is moving towards you and you are completely still, you will stay still after you pop out of the other side

>>215896678
Well, from what I understand, this is the equivalent of being in a platform going up extremely fast and it stopping abruptly. It's the same as of going up on a platform until it hits the roof, but the roof has a small hole that'll make only you go through it.

I changed my mind, it's definitely B
It's easier to figure out when it's like this; you are magically stranded in mid air and a portal is moving towards you horizontally. It's either you must be ejected out of the exit portal, or it's literally impossible to exit and you are forever locked in inter-portal limbo

It's B.
Your body is simultaneously moving (emerging from the portal) and standing still (lower body).
At the end of your traversal only the former remains, so you're going to to end your immersion with your whole body having the momentum of the movement your upper body had.
The way to think about it is that there are two identical world, and two of you are entering the other world. You're stationary in your own world, but the other world is slamming toward you. Once you're fully in the other world it continues to be in motion, whether you or it are moving is all the same as motion is relative.

Arguments based on energy preservation are false, because portals break energy preservation by definition. It's trivial to create infinite energy with portals.

>>215896405 (OP)
You are not moving so you have zero speed why would you acceleate coming out of the portal
it's A

>>215897597
You wouldn't be ejected, you would just move out of the exit portal
If you were halfway through, the entry portal could be moved back and forth, which would move you back and forth out of the exit portal, but you wouldn't be shot out of it
As soon as you are 100% out of the exit portal, the entry portal cannot affect you anymore, but there would be no momentum coming out of anywhere, even if the entry portal was moved towards you really fast

Portals close when the surface they're on moves. I'm not counting the neurotoxin level.

>>215897624
>Once you're fully in the other world it continues to be in motion
no?
the piston stops moving when it touches the thing
which means the world inside the orange portal stops moving relative to the world outside the orange portal
there is no reason for you to be still moving after you are fully inside and the portal stops moving

>>215898108
at the point when the piston stops you're entirely in the other world, so it stopping relative to your original world is not relevant to your motion at that point

>>215898207
>so it stopping relative to your original world is not relevant to your motion at that point
it is relevant
the momentum you have is 0 it's the world/universe inside the orange portal that is moving and it stops moving when you are inside meaning the world inside the portal also has 0 momentum at that point

>>215896405 (OP)
B obviously. Just imagine yourself going through the portal yourself.

>>215898316
i imagined and it's A howalthougheverbeit

Suppose you are at the exit portal's side and you are looking into the exit portal.
When the entry portal moves, to you, it will look like the guy is coming towards you fast.
Earlier we supposed that this guy is fixed in mid air magically. To this guy's perspective, as soon as he goes through exit portal, the entire world is moving backwards. However in your perspective, everything including you is stationary, and that this guy is going through mid air at fixed speed. Both are the same thing.
To put it simply, the moving entry portal's momentum is transferred to the guy.

Get a bottle, draw a dot and suppose it's an observer, and insert a pencil into the bottle. And then move the bottle so that it engulfs the pencil. to the observer who is stationary along with his entire world(the bottle), in both case, the pencil is moving. In the pencil's perspective, either scenario can be interpreted as the entire world moving towards it.

in my country it's definitely a
we don't do b here

>>215898566
the portal stops moving after the guy is inside in the original question by the way

>>215898672
That's completely irrelevant

>>215898686
check>>215898304

>>215898566
Yeah, to the observer the person would be moving, but that doesn't mean the person has momentum, nor will them acquire any
If i'm in a moving train, a person standing still outside of the train will seem like they're moving, if the train stops suddenly, i will be launched forwards, because now i'm in the same "world" as the person standing still, but retained the momentum from when i wasn't
In the portal case, the world that's moving is the exit portal's, not mine, i'm still in my world and will retain no momentum, when i cross the exit portal, the world will be moving in my perspective, not me

>>215898304
you obviously have momentum in the orange portal world, you are emerging from a protal, moving out of it
in that universe, you are moving
the moment the portal stops you're entirely in that world, so it stopping would affect you and that entire universe the same

>>215898787
From the perspective of the exit world, you're not moving in the entry world, so it follows that once you're in the exit world, you continue having no momentum
The thing that's moving is the entry portal, which has no way to give you any momentum

>>215898700
>>215898730
Just imagine this super simple scenario.
you are hovering in mid air, completely fixed in one place, with a jet pack.

1. if you fly into the orange, you will come out from blue with your momentum conserved. self explanatory.
2. If the box moves into you, you will stay in your place, but the box would be keep moving. to a stationary observer moving along with the box, this is the same as you moving.

"but the only moving thing is the orange in the original scenario."

It's literally the same in this scenario. The orange portal contains an entire identical copy of the world. To the guy, orange portal moving towards him is literally same as an exact copy world moving towards him.

>>215899140
the box stops moving when the guy is out of the portal tunnel thing in the original scenario

>>215899140
There is no box anon
Your analogy would work if it only had the the long part between portals, since the entry world and the exit world are the same (ie, a person outside of the box and a person inside would have the exact same perspective)
That long part moves into you, you enter and exit it. To an observer, you didn't move at all, the long part did, so there is no reason why you would move after coming out

>>215896405 (OP)
For me it's easily C: I kill myself

>>215896405 (OP)
It's A.
>NOOOOO ACCORDING TO SCIENCE IF PORTALS EXISTED IN REAL LIFE [bla bla some irrelevant gay faggot mental gymnastics]
Don't care, didn't ask.

>>215899228
If the box stops, you will continue to move in same direction. Because the momentum transferred to you when you entered the portal still remains. If this was real world, air resistance would stop you eventually or you will stir your jet to stop yourself. If this was done in space, you'd go in the same direction forever until you hit the wall.
Box moving into you is literally the same as you moving into the box. And when you moved, you had momentum.
It doens't matter if the box stops as soon as the man completely enters the portal, or that it goes the same way infinitely.
The world was running into him, and as soon as he entered that world the world stopped; then this automatically means that he is moving instead.

>>215898787
>you obviously have momentum in the orange portal world
you don't tho
it's the world inside the orange portal that has momentum towards you
when the piston stops world no longer has momentum towards you and when your momentums match you are both stationary to each other

>>215899509
>If the box stops, you will continue to move in same direction. Because the momentum transferred to you when you entered the portal still remains.
this literally contradicts the "super simple scenario " example you just posted

>>215899641
Ditch the original scenario and consider my horizontal scenario with the man fixed at midair without any platforms to stand on. And for the sake of convenience let's do suppose that the portal(and the piston hosting the portal) stops at the EXACT moment when the last molecule composing the man's body enters the entry portal. The result in this horizontal scenario applies exactly the same in your original, vertical, portal dropping down on you while you stand still there scenario.

Listen to yourself, slowly
Is your house moving when you walk into it?
