The difference between a normal-space event and a hyperspace event is academic. We can't know the difference. No information escapes that border.
Academic? It's not academic to the people that the border will overtake.
Once you cross that border you're either unable to communicate because hyperspace is damaged, or unable to communicate because you're dead.
That border is a like death, if you think about it. The only way to find out what's on the other side is to cross over and find out for yourself.
Careful, sir. You're starting to sound as if you've contracted a bad case of religion.
