The problem with finding a physics bug is that it's liable to be amplifiable. Break conservation laws just a little bit and suddenly you have potential for exponential runaway leading to an unplanned reality excursion, and say goodbye to your light-cone.
- justinclift 9y agoWell, by definition the behaviour would be undefined so could go any which way. ;) Modern day VM software has various levels of exception checking, and code to catch/mitigate/etc when bugs crop up. So, a universe-capable simulator might have any kind of behaviour if/when a bug occurs. It doesn't need to be an unbounded, runaway scenario. :)
