Time travel allows movement between different points in time without experiencing the intervening period, analogous to moving through space. It requires a flux capacitor that uses 1.21 gigawatts of power, as developed by Doc in two working time machine models. Potential after effects of time travel include hirsutism, excessive hair growth in abnormal areas, and Parkinson's syndrome.

1. Time Travel - “T r avel is more than the seeing of sights; it is a change that goes on, deep and permanent, in the ideas of living.” - Miriam Beard

3. Development The Flux Capacitor is the core component of the time machine which requires one point twenty-one jigga watts (1,210,000,000 watts)

5. After Effects Hirsutism is the excessive hairiness[1] on humans in those parts of the body where terminal hair does not normally occur or is minimal - for example, a beard or chest hair. It refers to a male pattern of body hair ( androgenic hair ) and it is therefore primarily of cosmetic and psychological concern. Hirsutism is a symptom rather than a disease and may be a sign of a more serious medical condition, especially if it develops well after puberty .

6. And unfortunately Parkinson syndrome.
