3. Years of watching sci fi has affected my brain. As soon as I heard the premise for Terra Nova I started trying to figure out how they could avoid destroying the time/space continuum. Dad and I decided that they must have slipped into an alternate dimension, which actually satisfied our desire for logic. Immediately after we decided this, the show went on to explain that this was exactly what had happened.
4. I have no problem with people going back in time as long as they move to another dimension so as to not disturb the space/time continuum.
5. I become addicted to Twitter when I have a stack of papers to grade. This both distracts me and has the added bonus of making me sound like a total whiner for several days.
