As Max Tegmark mentioned on this Rationally Speaking podcast quantum immortality might only work if the universe is infinite.

I don't have bandwidth for a podcast just now; so 'infinite' in what direction? If the number of MWI timelines can be divided infinitely, then that seems like it would suffice, even if the universe is finite in many other ways.

As I recall, he doesn't believe the universe is infinite in any direction.

Did he give any reasoning for that belief? Eg, does assuming non-infinitesimal worldlines improve the predictions of the interference of double-slit style experiments?

Certainly not the latter.

If there were any perceptible grain to them, we'd be about a picosecond from the abrupt end of the universe-as-we-know-it.

Again from what I recall: scientists have not found any evidence of infinities, math incompleteness problems go away without infinities, and computer physics models work even though computers have finite memories.
