| Flux Capacitor Doc Brown's device that makes time travel possible: November 5, 1955. That was the day I invented time travel. I remember it vividly. I was standing on my toilet hanging a clock. The porcelain was wet. I slipped, hit my head on the sink. When I came to, I had a revelation. A vision. A picture in my head. A picture of this. This is what makes time travel possible. The flux capacitor. It's taken almost 30 years and my family fortune to realize the vision of that day.
