Poetry can follow a strict structure, or none at all, but many different types of poems use poetic devices. Poetic devices are tools that a poet can use to create rhythm, enhance a poem's meaning, or intensify a mood or feeling. These devices help piece the poem together, much like a hammer and nails join planks of wood together.
Hyperspace (science fiction) Hyperspace is a method of traveling sometimes used in science fiction. It is typically described as an alternative region of space co-existing with our own universe which may be entered using an energy field or other device. Travel in hyperspace is typically depicted as faster-than-light travel in normal space.
Perhaps the most common use of the concept of a parallel universe in science fiction is the concept of hyperspace. Used in science fiction, the concept of hyperspace often refers to a parallel universe that can be used as a faster-than-light shortcut for interstellar travel.
