Neither, portals aren't real.

Speedy thing goes in, Speedy thing comes out.
Thats what she told us, And she watched them build it. Everything connects back to her. Its A. The object itself requires momentum.

Don't be a turd. I think it's A. In order for B to be the case the cube would already have to be in motion. Since the cube isn't in motion it doesn't continue to move.

I agree. The object itself requires momentum or else it will just plop right out. She said we needed momentum, and she's the one who knows everything about the device.

Portals cant go on moving surfaces. The game fucked up its own rule with the pipe cutting scene.

What debate? It's A. Never even played more than the Portal demo.
All you're doing by moving the warp gate quickly is making the cube show up quickly at the other side. But it has no momentum, then gravity makes it plop.

actually it depends on how the surface is moving. If anything making the rule that 'portals cant move' contradicts the rules of the entire series as the portals to xen and the portals to the combine homeworld move.

b. the momentum is created as the object extrudes from the portal at such a speed

A.
The cube doesn't have potential energy to be converted to kinetic energy

When my asshole launches onto my big block dildo, it is my asshole that has momentum, not the dildo.

If a portal is moving 100 mph, and you push it 99% past a cube, but not completely, then the cube moves through the exit portal at a speed of 100 mph. This introduces the kinetic energy to fling it.

To further draw out my example, the cube exiting the exit portal at 100 mph. Even as the cube slows down on exit, the rest of the cube is being propelled through the portal at 100 mph. The direction of the piston doesn't matter so long as the mass is being ejected upward with that much force.

Space moving around an object doesn't give energy to said object. The portal is moving around the cube at 100mph, the cube isn't getting pushed out of the portal at 100mph. Forces do not give energy either.

Where does the kinetic energy comes from ? If it comes from the platform, when is it transferred ?

Let's imagine for a second the blue portal is right behind the yellow portal, do you still think the cube will fly up ?

If yes, then make a ring with your finger and move it down around a marble, because it's basically the same system. And your marble will not move.

>If it comes from the platform, when is it transferred ?
When mass passes through the portal gravity pushes it back through. At that point the piston encounters additional resistance.

Not with the force presented in image B, but certainly more than image A.

Gravity is a force, forces do not give energy. Gravity doesn't "push" anything. They only describe how objects interact.

I don't see why gravity would push it back if the object doesn't have any potential energy stored.

this. gravity doesnt push at all, it pulls. pulls things together. gravity is what makes this planet and every other large spatial entity in one piece.

Earth, Solar System, galaxy etc already moving with great speed through the universe. Objects already have great momentum just no in the frame of reference to other objects on earth with the same velocity.

Then objects at standstill in each other's FoR come out with no momentum, and those with momentum relative to each other's FoR come out with it.
Cant say that "it just reads what passes through and teleports" because objects at speed come out at speed, so whether it be the speed on entry of the portal, or the momentum of the object itself, should be B

the portal is moving... the space in front and behind are constantly moved and replaced..
the object isn't "gaining" momentum...
the object would float for a moment before gravity began to affect it and it flopped to the ground..

the answer is A

notice how Thor didn't go "flying"

This principal is what makes space travel so difficult. NOTHING stays in the same place, its always moving. Intergalactic travel between two specific galaxies becomes more and more impossible as time goes on if they arent moving in the same direction at the same speed.

this is it

>marvel science fiction
nothing marvel or DC could possibly say on science fiction matters at all.

the question here is wether the portal crashes down on the table or gently stops right as it touches down with the surface of the table.

Portals do not affect momentum ie. momentum (function of mass and velocity) is preserved.

From a physics standpoint,Object A hitting Object B is not just equivalent but **directly the same** as Object B hitting Object A.

Because all motion is relative, and there is no objective universal space, speed or location to refer to: Such concepts do not exist.

The picture shows a surface with a portal speeding down through air towards a stationary pedestal. But this is the same situation as the pedestal and the air surrounding it rapidly rising towards a stationary portal.

These two events are not just similar, they are literally the same, because its all decided based on which subjective reference frame you choose to ascribe to for that particular situation.

In other words, there is literally no difference between a speedy portal hitting a stationary object, and a speedy object hitting a stationary portal, because velocity is always relative to something and there is no reason we should prefer any particular object over any other particular object as being 'stationary'.

Therefore, B.
