switching hamster from duirnal to nocturnal?

Question
DO you think this can be done?       Why do you think some animals are nocturnal?  

Answer
I dont think that this can not be done as the hamster is a nocturnal animal.  Animals such as hamsters are nocturnal because the habitat in which they are found is too hot in the day and they are at risk from predators so they come out as it starts to cool down (at night)
