As they spoke, Lucien picked up this issue of 'Elements' and glanced at the title, only to discover that the author was one Telaviv that he did not know. He was a level-four arcanist and fifth-circle sorcerer.
"He's perhaps a newly-promoted sorcerer. Only such young people could've proposed the model without being burdened by experience…" Lucien thought to himself.
It was not because Douglas, Brook, Fernando and Hathaway would not consider the possibility of negative-energy state and antiparticles, and in what form they should coexist with the regular matter if they did belong to this world. However, even if they had such speculations, they wouldn't propose it recklessly but would wait until antiparticles were proved.
If they ever proposed a similar model, the only reason would be that the model would contribute to the discovery and confirmation of antiparticles and negative energy; it's obvious that 'vacuum ocean of negative energy' would not.
