Are there some impossibilities in science,math, social studies, and English in this film? Please help...it's homework.

If آپ mean things that doesn`t make sense... well Science teachs us that there`s no other world under our feet and we can`t actually have a figth with time...
Then, in social studies... In the real victorian England, Alice would have been fifteen when she was forced to get married and Hamish would have been forty (yes, that did happened in that time)
And I thinks that`s all I`ve seen... What homework do آپ have to do?
