This maybe a basic question to the educated. I wondered if anyone can describe or show the path the earth takes not only in relation to orbiting the moving sun but taking into consideration the movement of the milkyway as in rotation and expansion of the universe. Hmm thinking of it as i write maybe thats not so basic a question. Just a random interest of mine with not relevant education to work it out. Thanks in advance if anyone can explain in laymans terms. I can at present see the helical path (all be it bent) around the moving sun.
