What happens if a person travels faster than light in a space shuttle?
Ans) Interstellar space travel is manned or unmanned travel among stars. The concept of interstellar travel in starships is a staple of science fiction. Interstellar travel is conceptually much more complex than interplanetary travel. Intergalactic travel, or travel among different galaxies, would be even more complex.
Many scientific papers have been published about related concepts. Given sufficient travel time and engineering work, both unmanned and sleeper ship interstellar travel seem possible, while both present considerable technological and economic challenges that are unlikely to be met in the near future, particularly for manned probes. NASA, ESA and other space agencies have been engaging in research into these topics for various years, and have accumulated a number of theoretical approaches.
