Ryan helped his father with the dishes.

"It's the least I can do after you spent hours making dinner from scratch, dad," Ryan said while he scrubbed the burnt cheese coated pan with a steel wool.

"I enjoy cooking," Edward shrugged, "it helps me relax. My offer to teach you how to cook is still open."

"I'm barely home these days..."

"Your new wife doesn't cook, does she?"

"No..."

"You should learn how to cook unless you two want to spend the rest of your lives ordering take-out."

Ryan had to suppress his laugh when he thought of trying to explain to his father that Marlissa's favorite dish was his cum. "Sure, maybe when we get back from Paris, dad."

"It's a date then!" Edward laughed.

"So, dad, I have a question for you..."

"Yeah?"

"Do you believe in the existence of other life beyond Earth?" Ryan asked.

"Maybe," Edward shrugged. "Have you heard of the Drake Equation?"

"No."

"Astronomer and astrophysicist Frank Drake came up with the Drake Equation in 1961. It is used to estimate the number of active, communicative extraterrestrial civilizations in the our galaxy but of course it only estimates values for several of its factors that are highly conjectural, the combined effect being that the uncertainty associated with any derived value is so large that the equation cannot be used to draw firm conclusions."

"Okay..."

"The equation goes like this: where N is the number of civilizations in the Milky Way Galaxy whose electromagnetic emissions are detectable, so it is equal to R, which is the rate of formation of stars suitable for the development of intelligent life, multiply by fp, which is the fraction of those stars with planetary systems, multiply by ne, which is the number of planets, per stellar system, with an environment suitable for life, multiply by fl, which is the fraction of suitable planets on which life actually appears, multiply by fi, which is the fraction of life bearing planets on which intelligent life emerges, multiply by fc, which is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space, multiply by L, which is the length of time such civilizations release detectable signals into space."

"Okay..."

"So depending on the parameters we are either alone in the galaxy or there are a hundred other civilizations."

"So there could be sentient life in our galaxy?"

"I never said that," Edward replied. "The Fermi paradox notes that with the lack of evidence for and various high probability estimates of the existence of extraterrestrial civilizations elsewhere in our galaxy, Earth should have already been visited by extraterrestrial aliens, or at least by their probes."

"Okay, so what about the rest of the universe?"

"Maybe," Edward shrugged as he wiped a plate dry.

"What about multiverse?"

"What about them?"

"Does a multiverse exist?"

"Could a multiverse exist?" Edward corrected. "Theoretically, sure why not? In reality? Who knows. That's what people like your mother and myself think about as part of our careers."

"Huh..." Ryan hummed, thinking how difficult it would be to explain to his parents that their new daughter-in-law is in reality a demoness from another dimension and he had used magic to summon her.

"Why do you ask?"

"Oh, I was just wondering that a common theme among ancient civilizations are creatures from other planes of existence."

"We will probably travel through a stable wormhole to the other side of the galaxy before we can use magic to summon demons from the Abyss!" Edward laughed.

Ryan laughed with a bit of nervousness his father did not detect.

"Speaking of fantasy, after we're done here I'll show you my new D&D miniatures downstairs."

"Sure, dad."
