Truth findable, in all hypothesis

if we list up all possibility, there is true hypothesis.

from Sir arthur conan doyle

   if there is 2 hypothesis,
   that 2 cover all possibility, = 100%
   and if 2 hypothesis have no mutual possibility,
   => one of them is true.

all possibility list up example:

       1⃣ future is predictable                 hypothesis A
       2⃣ future is not predictable           hypothesis E
       3⃣ hypothesis A + hypothesis E = all possibility

         =>  if hypothesis A is right, hypothesis E is wrong.
         =>  if hypothesis E is right, hypothesis A is wrong.

conclusion

       if you find all hypothesis,
          you can find true hypothesis
       = you can solve all problem,
       if you have enough time.
