It seems comprehensibly big. It would take between three and four years to walk around the Earth, walking for a sustainable number of hours at a reasonable pace every day, if you could walk around it in a straight line.
Walk on the surface of a sphere, in a straight line?
A straight line in elliptic geometry, presumably.
That’s called a “geodesic”. I’m not sure why they don’t just call it a “line”, but they don’t.
[joke mode] congratulations, you just walked into the ocean. [/joke mode]
Now, about looking down at the grand canyon floor from the glass platform to engage your visual cortex?
