Whoaaaaa, that escalated quickly! Vivian blinked at the sudden information overload that Professor Berkovich had dropped on them. The Slytherin quickly shuffled in her bag for a clean piece of parchment, a quill, and her inkwell. She scribbled whatever information the Professor had said, not even caring that her handwriting probably seemed unreadable to people other than herself. She made it a point to rewrite them tomorrow, when she wasn't drained of all energy.

Ermmm... yeah, the Milky Way. She hoped she'd be able to understand things through her hearing. She didn't think she could write that fast and legibly. Her letter 'M' looked like a wonky 'W' now. She'll have to deal with that.. next time.

Moving on to the actual question, Vivian took a moment to absorb it in. That was straight to the point. Not even a daily trivia or interesting fact? No? SIGH. To be honest, Vivian didn't even know how many light-year away they were, but she felt it would be like a 5 or 6-digit number, considering certain circumstances. She raised her hand to share her thoughts. "We can't be sure about it yet, Professor, because we still remain unsure of the galaxy's size. It's pretty hard to measure, too." Besides, aside from making intellectual estimations, it was rather impossible to make it certain.
