“Ah, Drilos. I wanted someone to talk to, but I never counted on a conversation quite so hilarious. Not only are you saying I’m the multiverse, but also that I’m becoming something devoid of existence? Ridiculous. Right now I’m just a disembodied consciousness, but as long as I exist in a void then the void won’t be a void. Right now I consist of energy rather than matter; it’s just nature’s way of compensating for the random space-time shifts of a being it apparently doesn’t want to die. Fission, fusion – I don’t make up the laws. The where and when of me are easy questions to answer. What am I? That’s a bit more difficult, but ultimately I was born a human, and nothing can change that. The how and the why of me – now there are two questions that are impossible to answer.”

“The supposition was that the difference in energy when n (or v) changes by one is therefore equal to hv, the product of the Planck constant and the vibration frequency was always derived using these pre-revolution mechanics. This was, of course, dependent on gravity having an effect on an atomic level, while acknowledging that it does not. Absurd right? But for a transition from level n to level n+ one due to absorption of a photon, the frequency of the photon has nothing to do with Planck…”
“Atom, for god’s sake, stop it!” Hannah interrupts.
“Stop? Stop what?”
“Why do you do this to people?” Hannah says, causing Lylitte to laugh, and the older woman to look at Hannah curiously.
“What he was going to eventually say is that we’re teaching the stem cells to sing their songs louder so that they harmonize and teach their melody to the host, once it’s introduced,” Billy explains.”
