Ruan Wenye, Huang Zhong, and Zhang Qican's job was to find the mathematical correlation between the composition of photon energy and the 'divine code.'
This sounds very complex, but an example makes it simple to understand.
For instance, building an interstellar spaceship that allows aliens to live onboard for an extended period, making sure that the aliens have the most comfortable living conditions possible within the spaceship.
Putting aside the spaceship construction technology for a moment, building a ship suitable for alien habitation is no easy task because humans do not know what aliens look like, let alone what kind of environment is suitable for them to live in.
But now, humans have obtained a house where an alien once lived.
This house, full of odd and completely different things compared to houses on Earth, baffles humans as to what is essential, what each item is used for, and moreover, how to manufacture these items.
