"That's right, that's exactly what I mean!"
Liu Feng gave Lin Xian a thumbs-up as if he were encouraging a grade schooler:
"So I boldly assert—"
"[Space-Time itself is not a wall without gaps!]"
"If Space-Time curvature really exists, if there are different Space-Times, different world lines, then there must also be something like a wall between these different Space-Times, preventing communication and traversal of time and matter from one to another."
"But there's no wall that's completely airtight! If the smallest gap in the Wall of Time and Space is the same as the smallest gap in the universe, the Planck length, then what if, in a Space-Time under a certain curvature, their Planck length is smaller than ours... Do you know what would happen? It's obvious—"
"[Particles from another Space-Time might be able to pass through the Planck gaps in the Wall of Time and Space, and cross over to our Space-Time!]"
...
Lin Xian listened to Liu Feng's description.
