There has yet been an instance in Halo’s canon where a Forerunner slipspace portal has allowed an object larger than it to pass through it. Therefore, we can not make an accurate inference/suggestion/conclusion that objects larger than a Forerunner portal can travel through it. If such a conclusion is made anyway, then an answer needs to exist as to why the Forerunners waste energy on opening portals larger than the object that is passing through it. (See: Halo 4) This irrefutably means that it is implausible for High Charity to have used the portal at Voi to travel to the Ark. ---------------------------------------------------------------- [i]*The Halo EVG page titled “Portal at Voi” states it is referring directly to the slipspace portal, and not the machine generating it. “COMPOSISTION: Slipspace field generated by a massive gateway machine” -Page 146, Portal at Voi, Halo EVG[/i][/url]
