Perhaps it depends on what you mean by "machine". A Turing machine 
cannot, but a generic machine most certainly can. For example, a machine 
could well verify that the temperature at a certain location is between 
20C and 23C at the current time. Given sufficient sensors and 
technology, there are many factual statements which are fully machine 
verifiable.
