I've heard that future spaceships traveling at near the speed of light will have to deal with massive amounts of radiation due to interstellar gas. I think these spaceships might also have to deal with radiation from star light being blue shifted. How close to the speed of light would one have to get in order for the little bit of star light that exists to be blue shifted to gamma rays? What energy would the photons need to be blue shifted to so that they would become deadly to humans?
