Nano-Technology
Genetic analysis
Genetic engineering
Dark matter (note that in which in its current hypothesis I oppose)
But the thing that we want to know: do aliens also crossdress?
Well???
Seriously, if you can, think about this. Would crossdressing occur in alien societies too?
If you need to- go ahead and limit it to humaniod or mammalian types of life forms.
But in light of the new Star Wars movie, and recent sci fi such as Firefly, Guardians of the Galaxy, and Avatar, where do crossdressers fit in? Is is always a behind-the-scenes thing? A bedroom fetish?
