Possibly, but not necessarily. The long way is relative. For example, I'm not sure that the core of Mars would count as part of the KnownUniverse.
Although if it were sufficiently far enough away, it would be impossible to work out whether it was long ago or not. --Admiral
(PeterTaylor) Only if you know sufficiently well how far away it is. ;-)
Um. Not as far as I see. As long as you know it is outside your causality cone (ie it is further away than the distance light could travel in the time difference), then it is impossible to know whether the event is in your past or your future, because it will appear to be different according to one's viewpoint. --Admiral
(PeterTaylor) I hoped that winking would be sufficient. Should I have added TIAJ?
