Titanic-1
On this world, the Titanic did not hit an iceberg and sink in the Atlantic, although possibly some of its owners might wish that it had. But that’s a backdrop to the real situation, which is this: there’s a lot of research to be done on Titanic-1 into the nature of timelines and divergence points, but unfortunately there are two broadly incompatible lines of research to be done. And each line of research has its own bureaucratic partisans. …Really, it’s almost enough to make one wish for Centrum to show up. At least they can be more directly thwarted.
