True theory's logical tie = circle shape

True theory's logical tie = circle shape

1⃣ if theory A use in certification of all other theory BC

   if theory A = true => theory B = true
   if theory B = true => theory C = true

2⃣ then how we confirm theory A = true ?

3⃣ if true theory exist in world, theory α may certificate theory A.

   if theory α = true => theory A = true

=> True theory's logical tie = shape of circle
