It is virtually impossible to escape this place!
It is meant to say something like "even though it is physically possible to escape, people are too scared to even try to do it - therefore, it is rather impossible to escape".
Not sure. Any ideas about the usage of virtually?
Note: The context in the sentence I provided is basically this: It is from an article about a community where people are so poor that
It is virtually impossible to escape this place!
