There are a lot of things that we can be certain are impossible. But claiming to know that something cannot be known is quite different than a claim postulating that you can't travel faster than the speed of light. But even if it is granted that the original claim was just a postulate that the uncertainty in QT is not due to ignorance (afaik there's no such postulate in QT), there's still a burden to define those terms in a non-contradictory way and I haven't seen such definitions.PeterDonis said:I disagree. For example, (2) is our current belief regarding traveling faster than light. You could quibble and say that we might discover a method of FTL travel some time in the future, but our best current theories of physics say it's impossible--not just that we haven't figured out how yet, but that there is no way to do it at all. Reasonable discussions of our best current theories make use of statements like this all the time.
