Has anybody ever walked around the world?
Well that depends on your definition of around I guess, sure people have physically walked around the north pole which would be 360 degrees around the earth, but of course the physical design of the human body and application of the laws of physics dictates it would be impossible to walk around the world a full 360 degrees apart from walking around at the poles, to do it over any other continent would require one to walk on oceans also, and that is not possible with the laws of physics in the universe (There has no land connection across the Atlantic ocean within the times humans have existed as a species, although on the other side it has been possible to walk from Russia to Alaska which has been bridged by ice) but a full 360 degree walking around the world would require one to physically walk on the Atlantic ocean. So no, nobody has actually walked around the world other than possibly on the continents of the Arctic or Antarctica only, outside of those areas it is only possible to w
