But now he had to take it seriously.
Firstly, the reason for the unity of the Morrowind Empire was that although 35 trillion people were distributed across a vast territory spanning 5,000 light-years, almost everyone recognized their Earthling identity, acknowledged the Solar System as the Homeworld of humanity, and knew there was no way back, and they were willing to fight for the survival of their race.
This was not a logical thought, nor even a reason. The recognition of one's own race was a natural emotion, without the need for reasoning.
Emotion transcended territorial boundaries and various background quantum storms caused cognitive biases, firmly linking almost everyone in the vast Morrowind Empire with the same belief.
But science didn't talk about feelings, only logic.
