Seeds of the word portal came from Latin, meaning a gate.
The word has grown from that simple definition over the years, so it means not only a gate. A portal can also be a door, a simple opening, or an entryway to anything. Current definitions aren’t limited to hollow openings. In medical definitions especially, the term portal doesn’t mean an airy gateway, rather a location where subtances pass.
Most of the world has been exposed to the idea of a portal from teevee shows or movies. Science fiction has taken the idea of a portal to mean a teleportation device. Within the broad category of sci-fi, there are time portals, space portals, and yes portals in which trash is discarded.
There is a fun offshoot of this idea of a portal being a passageway to somewhere else. It has to do with one of the most popular video games of all time, Portal.
A fantastic puzzle game, it involves traveling from place to place and solving problems while manipulating portals. Despite being a relatively short game, it requires some brainpower to strategically maneuver through the world.
And, let’s not forget, the game was successful enough to spawn a second version: Portal 2.
If the first iteration wasn’t enough, a person could renew the thrill with the next. Like entering another place, through a passageway…or something.
