That's not true at all. It has a physical meaning both in terms of the 3D spatial universe, and the 4D spacetime universe.
Whereas, the center of yannick's universe does have a meaning.
Of course, there are also other interpretations- the center of the observable universe, the center of expansion, and of course, the figurative center.

That's only if there are no flight delays.
it should be implied that the "years" are earth years.
Let's name the plane orbiting the largest star APOD. A single orbit of the largest sun would only take *1* APOD-year...
