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.
