It turns out that information leaks between universes at the quantum level. We think it accounts for all kinds of phenomena, from what drives evolution to strange insights and mystical experiences through the ages. The machine was built as an attempt to investigate and amplify them.
I recommend to you, in my last, an innocent piece of art: that of flattering people behind their backs, in presence of those who, to make their own court, much more than for your sake, will not fail to repeat, and even amplify, the praise to the party concerned. This is of all flattery the most pleasing, and consequently the most effectual.stanhope, philip, 4th earl of chesterfield
A face is a road map of someone's life . Without any need to amplify that or draw attention to it, there's a great deal that's communicated about who this person is and what their life experiences have been.
