Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54 × 10' light-years from Earth. If the lifetime of a human is taken to be 75.0 years, a spaceship would need to achieve some minimum speed Vin to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between vain and the speed of light c.
