"Every spot in the universe sees itself as being exactly in the center." Every point, every single point from string to particle to you to universe (u), of an infinite Universe (U) is the exact center of the Universe (U).
And at a trillion times trillion, times trillion, years ago those ultra-faint heat signatures from early universe bordered the horizon. And in a trillion times trillion, times trillion, years from now those same ultra-faint heat signatures from early universe will border on the horizon. And no universe traveler -- if there are universe travelers -- will ever close upon that horizon any closer, or farther away, than they start from. "Early universe" would emerge from that horizon ahead of the traveler; evolve toward him as he travels; and devolve and merge into that same distant horizon behind the traveler, as the traveler travels boundaryless universe to boundaryless universe, to boundaryless universe (horizon (dimensionality) to horizon (dimensionality), to horizon (dimensionality), always centered within the horizon constant) of infinities of universes (point-singularity (string) horizons).
A travel into the 'Big Mirror' (the immovable object of Universe (U)) that mirrors within to infinities (infinities of universes (u), the irresistible force of welling (to infinities of wellings)). The irresistible force of the immovable object.
