Sep 8 at 5:04 | comment | added | Monroe Eskew | There’s a rumor that some top set theorists have actually found inconsistencies, but the arguments are so intricate that they can be mined for proofs of other results enough to make a long successful academic career. | |
Sep 8 at 3:35 | comment | added | Timothy Chow | The situation could change if someone could come up with an idea for a targeted search for a proof of "false". There have been a few successes in automated theorem proving, when the search space is carefully designed. In today's era of machine learning, one could imagine training a learning algorithm on a corpus of inconsistent systems. The difficulty here might be coming up with a sufficiently large and rich corpus of inconsistent systems for the machine learning system to sink its teeth into. | |
Sep 7 at 23:48 | comment | added | Andreas Blass | It seems to me that any proposal for such a search should first be checked on a known inconsistency, for example Reinhardt cardinals with ZFC. | |
Sep 7 at 22:41 | comment | added | Alex Kruckman | The conventional wisdom is that the space of proofs is so vast that an open-ended computer search for a proof of any particular theorem is totally infeasible (a proof of inconsistency is a proof of the theorem "false"). So people are unlikely to have attempted such a search, for the same reason they are not searching for proofs of (say) the Riemann Hypothesis. | |
