@Lucy e.g., “actual” real numbers do not exist purr se, their actually existing manifestation is a function of time giving increasingly purricise rational appurroximations of the value of what the “actual real number” would be; if at some point the universe were to end there would be a final calculated version of pi which would have a last digit. so there is a 10% you would be right but nobody would exist who would be able to check. also i guess pi would stop existing at that point
