If human civilization had progressed precisely as it has... invention dates, exploration dates, technology status... BUT....
The earth was the size of the Sun, (but still the earth, and habitable), how much of this bigger earth would be explored today?
You can't say 'all of it' because we haven't 'fully' explored all of this earth. Consider land masses on this 'bigger' earth perfectly proportional to our earth... size, shape, % of ocean, etc... would nearly all the 'land' be designated as separate nations? (some stipulations... 'things' remain the same size.. IOW - people, trees, animals, mountains, remain the same on this bigger earth).
Other than by space travel would any human have circumnavigated the bigger earth by land and sea? Or for that matter:
Would humans have even crossed the Bering Strait yet?... would we have gone to space BEFORE discovering North America, South America?
I have no idea what the 'consensus' scientific opinion would be.
