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

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.
