Time travel

Time travel is a means of moving between different times in a given universe. Time travel is possible in almost all known universes of Pigverse.

Time machines
There are two types of time machines in usage: four- and five-dimensional. Four-dimensional happens through time, five-dimensional through time-space.

Five-dimensional travel is restricted from civilians. Only notable scientists, and honorable members of the Historical time-travel club are allowed to do so.

In a few esoteric incarnations, Alfred I. Piggy managed to complete a six-dimensional time machine to be used for personal gain and terrorism. This machine was later dubbed the Temporatron. The invention was stolen in several incarnations, and has since spread into many space-time locations within Pigverse.

Some types of Temporal anomalies may cause spontaneous time travel.

Logistics of time travel
Time travel in dimensions below the fourth one is technically impossible. Therefore, organisms living in the second or third dimension will have to time travel through the fourth, or occasionally the fifth dimension. All mechanical time machines are based on sending the passengers into the fourth dimension.

When a time traveler reaches their destination, the universe is split into two parts. In one, things continue normally as if the time traveler had never arrived. In the other, the time traveler arrives normally. Using a four dimensional time machine only allows the user to return to the original universe, therefore preventing people from changing the past. Five-dimensional travel allows the user to choose their returning destination.

Time travel is only possible to the location of the earliest working time machine. However, due to the efforts of Swine, a time machine was successfully placed into the year 5 billion before the beginning of time.

Notable time travelers
The Alphabet Bird can travel through time at will, and take anyone or anything with itself as it does.

Swine is capable of near-spontaneous time travel, and can take with him people he touches or medium sized objects.

Piggy, Alfred, Captain Fat-Piggy and Piggy 2B0F36 form a terrorist group called the "Bunch of Bickering Buffoons" and utilize a six-dimensional time machine in one unusual incarnation. Their current whereabouts in most incarnations are unknown, and they are wanted for temporal crimes.

The members of the Historical time-travel club conserve and document knowledge and artifacts previously thought to be lost.
