Chromis said. ‘The Janus anomaly changed history. The existence theorem says that it is always much easier to find a solution when you can be confident that one exists. Within a hundred years of your departure, there had been cataclysmic breakthroughs in fundamental physics. Janus taught us to look for loopholes in theories that had looked watertight for decades. Eventually, we had our own frameshift drive. It wasn’t as efficient as the Janus motor, and probably didn’t employ anything like the same principles, but it sufficed.
