Comment on Which is it Lemmy?

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.

Does that actually loop infinitely? Don’t you just reach a terminal velocity and then maintain that momentum?

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.

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.

The cube wouldn’t necessarily heat up much while approaching terminal velocity.
Its close to infinite energy because you never have to reach the ground, so you technically have infinite potential energy but when you convert that potential energy into kinetic or some other type of energy, the vast majority of that potential will disappear instantly

But that doesnt really matter cause my argument of it breaking physics still stands. Little infinite energy and a lot is the same.
