If a neutrino passes through the planet Neptune and the next thing it hits is you as you are born, the Neutrino leaves the frequency of Neptune in that millisecond in your body. This happens because Neutrinos which move at the speed of light but also have a tiny mass are able to pass through objects and then pass through us.
The idea being (explained in my Laymans terms) that when we are in the womb and when we are born and draw our first breath, we are imprinted with the energetic fields around us. Your Human Design is calculated based on your time, date and place of birth.
