Warp speed. Conceptual computer artwork of streaks of stars representing travel at faster-than-light (FTL, superluminal) speeds. Although the concept is popular in science fiction, scientists consider it an absolute certainty that no material object can travel at or faster than the speed of light in a vacuum. It would therefore take several years to reach the nearest stars, and billions of years to reach the farthest known objects in the universe.
