The picture frame isn't a portal and therefore doesn't change the frame of reference, dumbfuck.

I'd say it's A because the cube can't possibly start flying away before the entire cube is through, and there's no reason it would randomly start flying away after being stationary when 99.99999999% of it is through.

>> No.5661566

>>5661558

It's not stationary when 99.9999999% of it is through. It is moving at the same speed the portal is moving. See

The portion of the square that has passed through the portal is moving relative to the blue portal at the same velocity as the orange portal was moving relative to the square before it passed through the portal.

Both of the examples of portals violating conservation of energy are wrong. In both these cases the additional energy is coming from the force of gravity,

>> No.5661594

>>5661593
But where's the work in moving the portal from the exit (lower) portal to the entrance (higher) portal?

protip: nowhere

>In both these cases the additional energy is coming from the force of gravity,

So gravity is being used up? No? Fuck off.

>> No.5661598

>>5661596
He's talking about the increasing of the velocity as the block travels downward. He forgot to account for the work bringing the block from the lower portal to the upper portal.

However according to QM everything is subjective to consciousness and the laws of classical mechanics are false so the law of conservation of energy/mass/momentum/etc is false.

So the answer is A ?

1)orange portal moves at high speed towards cube
2)first atoms of the cube travel through the portal and emerge on the blue side
from here either of 2 things happen:
A)the atoms stay where they are. the rest of the cube teleports into the same space occupied by the first atoms, probably creating some sort of nuclear explosion
B)the atoms are pushed forward by the rest of the cube as it travels through. the emerging parts of the cube push the parts that have already emerged forward at the speed of the orange portal.
when the entire thing has come through all those atoms would not suddenly stop moving, the momentum would be conserved and the cube shoots forward.

Portals break continuous symmetry Hamiltonian therefore they break conservation (Noether's theorem). It is nonsense to appeal to conservation of energy when portals are involved.

Portals do not conserve momentum.

Bfags are so wrong it always cracks me up.

I like to think that portals supply their own energy, and the momentum is disappated in to the earth.
