that doesn't work, because 1/i = -i, so i would also have units of radians.

Also, I find "there's a lively discussion going on about whether this is on topic" hard to reconcile with you mod-closing the question. IMHO, mod powers should only be used in cases where a clear policy exists, and in this case I really think that's not the case.

@DavidZ I think you might have some kind of mistake while moving the conversation to chat - that chat room contains duplicates of the comments above, but not the ones that were made after them.

@ACuriousMind done, but honestly I think complaining about it is doing something about it. At the very least, it enables other users to realise that the opinions of the close voters are not those of the entire community, which I think is pretty important actually.

comment Why have our eyes not evolved to see “gluons”?
Closing this question would be a disaster. The issue doesn't really seem to be that it lacks physics content (it's about gluons for pity's sake!) but rather that it also contains biological content. It's irritating enough to keep closing questions based on philosophical hair-splitting about which things count as "physics" and which don't, but if we also start closing questions based on containing applications of physics to other fields then we're just completely lost as a community.

comment Symbolic dynamics of a multidimensional system
@DavidZ would you remind locking the question as well then, in that case? If there is dispute it should take place on meta. Close votes are meant for implementing policy, not deciding it, but often they get used as a vote for what the policy should be instead. That's happening here I think, and we should not let policy be determined this way. (I myself do not have the energy to start another meta post though. I only wanted to attract good answers to a decent question.)

@ACuriousMind is that really true? It doesn't complain if I click on "close", though obviously I haven't gone all the way to actually attempting to cast a close vote. Anyway my intention is not to abuse anything, just to draw attention to questions I think stand out as decent, productive and on-topic, especially in cases where this seems to be in dispute.

Posting a bounty in an attempt to counteract down votes and close votes. We absolutely should not be hostile to well formed technical questions like this, especially when it's under the guise of a philosophical nitpick about "physical content," whatever that is.

comment Spaceship split near event horizon
@Neil there is no contradiction. The event horizon is a point of no return, and if you pass it there is no way you'll ever make it back again. Eventually, no matter what you do, you will fall into the singularity. It's just that there isn't a sign to tell you that you've gone past it. Spaghettification and the event horizon are quite different issues - it's the spaghettification that disappears for a big enough black hole, not the point-of-no-return nature of the horizon.

comment Spaceship split near event horizon
@Neil the magnitude of tidal forces depends on the mass of the black hole. For smaller ones, yes, you'd be spaghettified long before you reached the event horizons, but for big ones like the one at the galactic centre the tidal forces at the event horizon are negligible - you would experience it as a region of space like any other.
