I state my conclusion first, there is nothing like that on this universe. The reason I think so is not I am a buddhist but I feel it is nearer to truth than others. However, there are some historic or epoch-making something like pyramid in our world. They are changing materially but the fact that they made an impact to human race would not change as long as our civilization lasts. I think they have following features, that is they made by leading edge technology at that time. It means they caught age. I want to make something that catch a age.
