I was thinking about Korea (because I watch Korean programming sometimes), I was wondering exactly what the time difference was, which led me to wonder exactly were would be the precise other side of the Earth from here, then I thought how I might determine that (apart from Google) with a globe, and then I thought how much shorter a distance of travel it would be to just get their via a straight tunnel, which made me wonder at the changeover of the direction of gravity, which made me think that probably gravity would get weaker the closer to the center of the Earth, it wouldnt just flip over, So then I thought, Can that be right? Does gravity get weaker at the center of an object? So then I had to Google that, and sure enough. So then I thought, well then the suns gravity must also be weaker at the center, unless there is some sort of different cause than mass that is the source of gravity in the sun... just thinking about it...
