Jake, at 32 years old, time-traveled into his five-year-old self without paradox. A temporal quantum entanglement—mutual particles communicated across time, across dimensions, across space.

He left a note for the five-year-old—Don’t fret, I’ll be back. Stay inside. Don’t go anywhere!

“Where am I? What’s wrong with my body?” Young Jake ran outside, clumsily disregarding the note to stay inside, he fell off the hovering domicile and died.

“Connection terminated.”

“What the hell? Oh, no ...” Jake 32, now five, knew what that meant. At some point, he’d turn 32, swap, and die as entangled, no matter the method.
