To avoid using of extremely big numbers to express distances in Universe. Solution: Using a new mathematics operation called ReExpOp (math symbol is @)

Example:  5@3 = (5^5)^5 = 2.9802322388e+17 = 298,023,223,880,000,000 

                       2@5 = (((2^2)^2)^2)^2 = 65,536

                       3@4 = ((3^3)^3)^3 = 7,625,597,484,987

                       6@3 = (6^6)^6 ~ 10^28 = 10x10^27

  6@3 m = 10x10^27 m = 10 times bigger than Size of observable universe
