"WebFirst, get your speed relative to the Cosmic Microwave Background up to something like 99% the speed of light (possibly even closer). At some point, the incoming radiation ahead of you should then be blueshifted to the point where it produces a temperature like that experienced on Earth (and if you go much faster than that, you would burn up).
