Ben 10: Alien Force, Season 1

Professor Paradox:
I'll tell you my story in a way that you can understand. With a beginning, middle and end. We'll start in the middle. Los Solidad was built entirely because of my ingenious theory. A time tunnel utilizing properties which I discovered in quartz crystals. Which allows us access past and future events.

Kevin Levin:
Well for a genius it looks like you blew it.

Professor Paradox:
You don't know the half of it. So some tiny miscalculation on my part destabilized the experiment and ripped a hole in the fabric of reality. I was hurled into the event horizon. I must have spent 100,000 years there. I didn't age, or need to sleep or eat. Just exist.

Kevin Levin:
Heh, sounds pretty boring.

Professor Paradox At first, I went mad of course, but after a few millennia, I got bored with that too, and went sane. Very Sane. I began to learn. I now have total understanding of the space/time continuum, allowing me to travel anywhere and anywhen I want. Within reason of course.
