"What exactly... is Higher-Dimensional Space?"
Only after a long while did Klein take a deep breath and ask the question on his mind.
In this mystical world where charlatans, potions, and tentacled monsters filled the streets, suddenly hearing a term so steeped in modern physics gave him an absurd sense of dissonance.
It was like kneeling in a church and praying to the Evernight Goddess when the Archbishop suddenly came over, patted you on the shoulder, and said, "Let's study the Law of Universal Gravitation together."
"I majored in the humanities in my previous life, but I've read a few popular science magazines.
"Surely it can't be Higher-Dimensional Space in the physical sense, right?"
Klein shrank back against the sofa and continued asking.
"Generally speaking, you can understand dimensionality as the amount of information something can contain."
"Each additional dimension is equivalent to adding another physical quantity."
As Edwin spoke, he extended a finger and drew a line through the air.
"From two dimensions to three, you add 'height.' A sheet of paper becomes a box."
His finger continued moving.
"From three dimensions to four, you add 'time.'
"A stationary box becomes the life of a box, from the moment it leaves the factory to the moment it rots away."
Klein nodded.
This was still within the scope of his common sense.
Back when he was Zhou Mingrui, he had often argued about these higher-dimensional theories with people on online forums, mostly just to bicker with netizens.
"But under normal circumstances, higher dimensions only manifest in the microscopic world."
Edwin took a sip of wine.
"Because compared to three-dimensional space, the other dimensions are extremely unstable.
"They spontaneously fall toward lower dimensions."
Klein froze.
A physics term buried deep in his memories suddenly leaped into his mind.
"You mean... the
