Maybe could have a link to 969: Delta-P put in at an appropriate juncture in the explanation? 03:42, 21 June 2013 (UTC)

I may be missing something, but why are the teleportation rings given a dimension "each about two feet in diameter" in the explanation? There isn't anything in the comic. If there is a reason, please elaborate.--Pudder (talk) 16:02, 1 September 2014 (UTC)

Perhaps it's in reference to the apparent size of Portal gun holes? I'm not sure, anyone else have any ideas? Leafy Greens (talk) 02:29, 16 November 2014 (UTC)

I got Nerd sniped by the portal gun idea, and how it breaks the physics laws. If you placed one on the bottom of a lake, after an hydroelectric dam, and the other on the top of the dam, you'd have an infinite supply of energy, as you filled the dam forever and ever. A truly infinite supply, not like a star that takes billions of years to extinguish. That has to brake the laws of thermodynamics and entropy at some point. Aligning both portals in a vaccuum on earth's gravity would allow infinite time under 1g acceleration for anything dropped between portals. Hitting the speed of light would take 1 year, give or take (if you followed Newtonian cinematics), at which point my brain BSODs on this thought experiment. It suggests that the portal consumes an infinite amount of energy to remain open and cannot exist on this universe. Otherwise, we just discovered a moto-continuum and a source for infinite energy. Edit: this comment makes sense on the Delta-P page (969), so you should follow it. Gonemad79 (talk) 20:02, 17 September 2015 (UTC)

Presumably, teleportation rings do not create energy. Therefore, if the two rings are at different elevation, items put into the higher one will come out shooting from the lower one (converting the liberated potential energy into kinetic energy -- as normal falling would). Conversely, items put into the lower ring will have to be pushed very hard to make them come out through the higher one (equivalent to the pushing required to lift the passed object to the higher elevation). Hence, placing one deep in the ocean (and the other above sea level) won't cause anything dramatic to happen. The deep water will be held back by gravity and not push out through the ring.

Wait... What if you somehow put one of the teleportation rings through the other? What would happen then? Vince7778 (talk) 23:01, 17 January 2017 (UTC)

If this follows the mechanics of Portal, then all rings must be strictly the same size and one ring won't ever be able to pass through another. Zowayix (talk) 03:29, 7 April 2017 (UTC)
But: Do all objects have to be put through the first ring completely to reappear in the second, or is travel between the two instantaneous? If so, even rings of the same size would fit inside each other at least (alomst) half way and strange things would probably happen... --Felis Catus (talk) 20:27, 28 May 2017 (UTC)

A different problem with breaking physics in D and D occurs because a turn lasts six seconds and passing an object doesn't end a turn, if on your turn you hire people to pass objects in a circle, you could make that object move as many rotations as you want in just six seconds, meaning that you could have it accelerate infinitely in just six seconds! YAY LOOPHOLES! (You could also end that turn by throwing it at something, like a monster..... YAY LOOPHOLES!)

A better thing for her to say is "No metagaming," because not only is information unknown to his character (what D&D is) influencing his actions, but he's also attempting to create a game within a game. Though I agree with the description that it'd be nicer to let it play out to some degree, he missed a joke opportunity. 01:38, 21 August 2018 (UTC)

D&D pun missed: no "recursing" but "cursing" someone with magic is presumably OK. Nitpicking (talk) 21:15, 20 August 2021 (UTC)
