I've just realised that according to the Bayesian argument, the chances of someone
with an infinite world-line being ANY specific
age are infinitesimal. (It also makes the chances of me being the age I am pretty
infinitesimal too, come to think of it). That
would seem to indicate that the Bayesian argument *assumes* that infinite world-lines
(and possibly infinite anythings) are
impossible. Sorry I took so long to spot that objection to the SSA argument, which I
will call (4).
