SUMMARY
The discussion centers on the effects of traveling at speeds close to the speed of light (c) on an observer's particle horizon and coformal time, particularly in relation to the Cosmic Microwave Background (CMB). It highlights that an observer moving at near-c speeds will experience significant alterations in their particle horizon due to relativistic effects, which will also influence their perception of Hubble expansion. The question raised indicates a solid understanding of relativity and cosmology, warranting its classification as a B level inquiry.
