A: Is there an example of a sigma algebra that is not a topology?

KalidasI am just a beginner in this domain, so pardon me if my reasoning is wrong. I will be happy hear correct answers from the members. I am going through Measure Theory by John K. Hunter online material (https://www.math.ucdavis.edu/~hunter/measure_theory/measure_notes.pdf) and my reasoning is based ...

This new answer, to an old question, is very much incorrect.
Would be good to have it deleted if possible

@ТymaGaidash Not a wise decision by some diamond mod since there is now no signal to users that such PSQs are off-topic and should not be answered. Not to mention that the answerer - who continually ignores EOQS policy - has been rewarded with ~150 rep. Is there any hope for site quality when nothing can be done to stop such policy violations.
