Harrison Clark decided to accept Rainer's proposal and approved his resignation from the position of Dean of the Summit Science Academy to focus on the original concept design of the Space Transportation Network.
With the theoretical knowledge level of 2100, Rainer would never be able to design the Space Transportation Network.
He shouldn't have even thought about it, let alone attempt to build a theoretical framework for such a massive project like Leonard Lewis, a science fiction writer at most.
However, Rainer was one of the founders of the Solution and Harrison Clark's closest comrade.
Harrison Clark gave Rainer a great deal of future scientific knowledge.
