Above all, the diameter of the sun is 1.39 million kilometre, for 109 times of the earth, because we go in the surface, accumulate R^2 of π of computational formula S=4 through ball surface so, we can reach, sun surface accumulates 11881 times be earthly surface, that is to say, if want the world of whole sun area, that needs to use the of 11881 times time that takes the world now at least, how long to walk along whole world to need that now?
I am checked, true go to what every country goes, it is the traveler of a France: Kathy? Heart? Peikeer. Spent 18 months 26 days, it is 573 days probably, if this wants conversion to become the world of sun size,be 6807813 days, namely 18651.5 years, the person cannot live for certain so long.
Nevertheless, I was checked again, neither one the country goes, dinkum annulus swims of the earth, record of current auspicious Nisi world is 40 days, if conversion becomes the world of sun size,be 4360 days, namely 12 years. This also is impracticable.
If that circles earthly circuit by air? A common plane circles earthly circuit to want to use 50 hours, if conversion becomes the world of sun size,be 227 days. This seems to rely on chart a bit. But this is not to take whole appearance, just circled a circle just.
Want each country to walk along the whole world to need 18651.5 years so, perhaps take a ship annulus swims is 12 years, if be pure,circling circuit by air is 227 days, of organic still meeting. But take a ship and the plane is to circle a circle merely, either go step by step.
As a scientific subject, final finally, I still want to say, if the world is so great like the sun, what should know this gravitation is to comparative is big, actually, never mention it annulus swims the earth, the mankind does not have method to exist at all. And exist namely, the mankind also should stand not to rise, can be pressed on the ground to cannot move by gravitation dead deathtrap. And in that way quality, the earth can be ignited certainly, become a star, that estimation must bake the person did not have.
