Sometimes Science Is More Art Than Science, Nana

I am with my Nana, and I am watching “Rick And Morty.” One of the episodes revolves around concentrated dark matter. I go into the other room to check on my Nana. 

Nana: “What’s that show about?”

Me: “It’s about a boy and his grandfather who go on adventures. The grandfather’s a scientist, and he’s perfected dark matter, which gives him faster-than-speed-of-light travel.”

Nana: “What’s dark matter?”

Me: “Okay, you and I are made of matter, right?”

Nana: “Yes.”

Me: “Dark matter is basically antimatter.”

Nana just has a blank look.

Me: “How do I explain this? Everything on Earth is made of matter, but space is basically antimatter because it has no substance.”

Nana still has a blank look.

Me: “I’m only confusing you, aren’t I?”

Nana: “Yes.”
