Hey, here's a fairly interesting question! What happens to the background black-body radiation when you start moving faster? Obviously, it gets doppler shifted. What does the distribution of radiation with wavelength look like? Is it still a black-body curve? All sorts of interesting questions with this one! -Bob Myers
