B. Because it’s relative.
Also, because Cave Johnson is your dad.
Which is it Lemmy?

Has to be, for the particles to clear the second portals entry they have to be moving at a relative velocity to the first portal at the same rate the first portal is moving

B. this is because of Galilean relativity i think maybe

Real world B. In-game, A

What? That cube will definitely get crushed, no idea what’s up with A or B but that cube will get crushed and I’m looking forward to it

Assuming the black platform does not fit through the orange portal, and the moving panel with the orange portal stops on impact (which is what appears to be true because on the blue portal side we see the surface of the black panel), then the cube is no longer moving relative to the orange portal and therefore has no momentum. Once the cube is entirely on the blue side of the portal it will be affected by the gravity on that side and slide down as if on a ramp (A).

It should be a.
Imagine if the cube was actually a long rod and the orange portal start with the column half way inside it. Then the orange portal moves, in this case it would be very odd for the rod to jump in this scenario like in case b, the thing you would expect would be for the rod to stay still (besides tipping sideways a bit) consistent with case a.

Portals aren’t real, you know.

If you considered the cube to be 1m^3, the time at which the cube enters the orange portal t~1~
TheStaffmaster@lemmy.world 2 weeks ago
A, but it would have the average of the two states.
arc99@lemmy.world 2 weeks ago
Most likely option is it flops out but only if the angle is sufficient for the cube to overcome its centre of gravity and topple. And do so before the orange portal rises again. Also depends if the downward orange portal directly touches the base or not, since there might be a bit of a “lip” to overcome too.

I don’t know enough about space-time. Does distorting space transfer energy to the matter in that space? How about time? I think it must be A, out of the options.
Otherwise the future of man is less ‘sustained ftl travel’, and more ‘giant space slingshot’.

the cube isn’t fully lined up with the portal so the collision with the edge of the portal/platform causes some source shenanigans and ends up being option b
WorldsDumbestMan@lemmy.today 2 weeks ago
It gets stuck in between, with part of the cube not being fully outside, it hangs on the edge.

This only works if you treat the cube as one object anchored by a small part. In reality, objects are a bunch of particles each with their own momentum held together by forces between each particle usually strong and springy enough to cancel out differences in momentum. This is why all objects tear apart if enough uneven force is applied on them.
If the portal stops partway through the cube, the stationary bottom part on one side of the portal and the top part still carrying the momentum of recently exiting the portal will have very different competing momentums. If the cube’s internal forces win out, the overall momentum will average out, and the cube will fly up with a speed proportional to however much of it got pushed through the portal before it stopped. If the competing momentums win out, the cube will break into both stationary and flying parts.

Everyone else is wrong. (Ragebait.)
Speed of approach = speed of separation.
If the box left the blue portal at a slower speed than it entered the yellow one, the top of the box would be moving slower than the bottom of the box, which would compact the box dramatically during the transition, but we can see that its size is unchanged and it is still square.
The top of the box is pushed rapidly out of the blue portal by the bottom of the box being thrust into the yellow portal. (The bottom of the box is pulled rapidly up into the air by the top of the box which is already moving quickly.)

More importantly, what if I straddle the blue one?
Img pls?
AI_toothbrush@lemmy.zip 2 weeks ago
If you come out stationary wont you become a pancake of all your z axis compressed into a single infinitely thin plane? Also i think when the game calculates this it treats you as a point travelling through the portal plane and adds the plop worth of momentum as a compensation to not break the physics. Also if you think about it a lot of different situations already lead to extra momentum out of nowhere(classic portal above and below infinite loop as an example) so the portal in this case adding momentum doesnt break physics cause portals already break it. Also theres a problem of some people answering with the game physics in mind and other with the real world interpretation of it so this really is the perfect ragebait.
JustAnotherKay@lemmy.world 2 weeks ago
Does that actually loop infinitely? Don’t you just reach a terminal velocity and then maintain that momentum?
ericwdhs@discuss.online 2 weeks ago
Terminal velocity is only reached because the object (or player) is colliding with the air. Momentum is still being added. It’s just also transferring out into the air. You can kind of think of the object as being a fan blade running on zero power. It’s technically a source of infinite energy, but it might be hard to extract from that exact setup. If we could do this in the real world, we’d tweak it to just be water in a vertical pipe with a turbine extracting the free momentum.
AI_toothbrush@lemmy.zip 2 weeks ago
I mean yeah thats true but that still means the cube would heat up or something and then you could use that to generate infinite energy. The point is you can accelerate something to a speed without putting in the energy needed to accelerate it.
