Different Numerous Systems Correspond to Different Universes: Revealing the Secret behind Nikola Tesla Code of 3, 6, 9

The statement of Nikola Tesla that if you knew the magnificence of three, six and nine, you would have a key to the universe implies that there must be something special about these three numbers. In this paper it is demonstrated that the underlying reason for this specialty is the employment of decimal system ( which is a base-10 system in which the ten numbers including 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 serve as elementary particles to establish a numerous world) to describe the universe. If a different numerous system is employed, these three numbers of 3, 6, 9 may lose their magnificence or even may not exist. The investigation of the different patterns of the digital roots of the elements in the sequence { 1, 2, 4, 8, 16, 32, 64, 128} in different numerous systems is conducted, and it is shown that no repeated pattern exists in base-9 numerous system, and the repeated patterns in base-8, base-11, base-12, and base-13 numerous systems are different from the repeated pattern in decimal system. And it is proved that in a base-N numerous system, the digital root of the sum of the interior angles of a polygon is equal to N-1.
