A journey across the cosmos begins with a single question: What does it really mean to be flying through all of the galaxies in our observable universe? The universe is packed with structure, motion, and limits that don’t behave the way intuition suggests. From the Milky Way’s hidden momentum to the extreme edge where light itself struggles to keep up, each step reveals a new layer of the cosmic map. But the deeper the exploration goes, the stranger the rules become, especially when entire galaxies start slipping beyond reach. Prepare for a guided tour that challenges assumptions, expands perspective, and exposes the universe’s most elusive boundary.
