I assume that limit accounts for the time dilation, too. At the speed the particle was traveling it wouldn't have had much time in its reference frame to interact with the background radiation, even blue-shifted as it would be, right?
- idlewords 3y agoYeah, the model does account for it, and the time dilations are nuts. For the Oh-my-god particle (a similar early detection), I remember that it would have crossed a billion light years in what it perceived as a day.
- liamwire 3y agoImagining that reference frame is a beautiful thought. Galaxies and stars coming into and out of existence in real time, supernovae exploding like fireworks constantly as the entire universe zips by.
- jacquesm 3y agoUntil that trip ends by being snagged by some puny detector on an even punier planet that just so happened to intersect your trajectory. "I came across a billion lightyears, and all I got was this scientific paper". Not even a t-shirt...
