If you took the DNA from every cell in our bodies and laid it out end to end it would stretch 10 to the 29 power miles in length. That is an enormous distance! NOVA estimates the viewable horizon of the Universe as 28 Billion light-years wide. A light-year is the distance light travels in one year. Light travels at 186,000 miles per second or 6 * 10 to the 12 power miles. Multiplying this by 28 Billion light-years yields 1.6 * 10 to the 23 power miles wide. So our DNA is wider than the known Universe. WOW! I know that each cell has the same DNA but the epigenetics are different. Cells act differently and operate under different environmental triggers. So we could view each cell as an intelligent creature or at least a computer that is operating on its own but communicating with all the other cells. That is complexity beyond our wildest dreams.
