The shows that dense cores are produced with semi-regular interval space and time from one edge to other. At initial stage near edges is attracted inwards by gravity accumulation makes core edge. When grows mass up certain amount, it gathers other direction. Accordingly becomes isolated main parent has new This cycle repeats process propagates towards propagation speed few tens percent larger than sound speed. According theory, age difference for northwest-most southeast-most TMC-1 estimated be 0.68~pc/0.6~km~s$^{-1}$ = $ 10 ^6 $~y. consistent obtained chemical chronology.
