Movement Of Profit

   1⃣ we can predict movement of profit, with gravity.
   2⃣ we can predict high gravity place, with circle shape building, exist at many world strings
   3⃣ we can predict high energy place, with tower shape buildings

point:

   ・ invisible buildings, may exist ( in underground, in sea )

   ・ to think from energy level, tower may necessary to go to space.
