Titor claimed that the Many Worlds interpretation of quantum mechanics would be proven correct. If this scientific hypothesis is disproved it will falsify his claims. However, since he says histories 'diverge' his historical predictions cannot be used to prove or disprove his story. (Although they may make it more or less plausible.) Any claim, which is not necessarily true in all possible futures, cannot be used to falsify his origination in a future different from ours. For instance, Titor refused to answer any of the (frequent) requests for sports result predictions; he gave several reasons for this, one of which said that since his memories were of a divergent timeline, there would be no guarantee of the same outcome in our future.
2 Titor claimed that his time travel device utilized 6 caesium based atomic clocks, which are accurate to 1 part in 1015. However, on May 23 2005, researchers in Japan announced the creation of a new atomic clock using strontium atoms trapped in an optical lattice, which is accurate to 1 part in 1018. Titor says that to minimize 'worldline divergence' the most accurate atomic clock are preferred, which is hard to reconcile with the use of now 'obsolete' caesium-clock technology. This may be the first anachronism that undermines the credibility of the Titor story, although the actual precision of the clocks in the C204 (and C206) are not specified, and may exceed both of these in accuracy. (A research program capable of developing time travel might have superior time-keeping technology, and Titor says that his caesium clocks are actively
