An uninformed prior doesn't really make sense in this case. You have observed somethingness at least once but have never observed nothingness--only conjectured its existence. If 1) your observations are correct and 2) somethingness is mutually exclusive with nothingness then your prior distribution should approach [1, 0], not [0.5, 0.5].
