Question Do we want to consider removing (most) mass-imported questions
This is based on a question in Writing about revitalising the community and is pretty much a blatant copy-paste of Monica's answer there. Essentially, it's been suggested that we remove all mass-imported content, so we want to look at the feasibility of doing so here and to see if that's what peop...

Question Difference between 'AWPP' and standard quantum physics
Quantum Computers are considered a more powerful type of computer than so called 'classical' computers. While a typical classical computer could be considered as a black box that can solve Polynomial time (P) problems in polynomial time (i.e. 'efficiently'), a typical (universal, fault tolerant) quan...

Comment Post #275841 In addition, I've gone through a number of (~50) answers in that category and only about a tenth (so far, in my opinion) are what I would term 'definitely good enough'. Whether this is an argument for (more easy to enforce the rules?) or against (trying to enforce the rules won't work?) separate cate...

Comment Post #275841 On WB SE, there was a bit of an issue in that people were very good at ignoring these requirements. Having said that, this was at its worst when a question hit HNQ. We're also not on SE any more (and this is now a science site, so no more e.g. purely magic questions), so... Maybe this is enough of a ...

Comment Post #275820 I do see the issues about 'researched' though... Depending on what we set the requirements to be, I could see 'referenced' quite easily (but I'm biased on that one)

Comment Post #275820 Would different people understand 'rigorous' in different ways? Would be my main question - for one person, this could be a solid mathematical proof, for the next, a long detailed argument containing no numbers, so is there an easy way to reconcile this, or would that matter if we had it clearly writ...

Comment Post #275788 @sigma That idea potentially falls down if people are here *only* for that category, in my view, but it would make it easier to moderate everything

Comment Post #275787 @aCVn Would I put a citation to a NASA webpage in a paper? It depends - I'd download data on e.g. locations of astronomical objects and use that data. But NASA do publish papers as well, so it was actual science I wanted, yes, I'd refer to their papers. To me, this seems pretty reasonable for a categ...

Comment Post #275787 The more I think about it, the more I'm beginning to think that 'good enough quality for a paper' (even if nothing on here is ever actually suitable for a paper, the expected standard should be the same?) is what we want - if you want to start from equations, you need to at least cite either a review...

Comment Post #275801 I'm against 'scientific WB' - it narrows the scope down to a narrow subset of WB (although it appears that a lot of people aren't particularly aware of what WB actually is anyway, as far as I can tell), while simultaneously getting rid of questions about science that aren't about WB. As a scientist, ...

Comment Post #275787 I would also consider adding 'conference proceedings' to 'scientific papers' as these are potentially considered on a par with (if not more important than) papers in some fields e.g. Computer Science

Question Requirements of posts in Rigorous Science
To replace using the like of the 'hard-science' tag on Worldbuilding SE, we have the 'Rigorous Science' category. As evident in the name, this involves 'research' of some form, but what does this mean? That is, what are the requirements for a question in that category and what are the requirements...

Answer A: How efficient can my neutrino detector be?
Both the (current) answers to the question state that it is not possible for your idea to work. Aside from the fact that you are explicitly not asking for a feasibility study, the obligatory XKCD reference shows that it's all about the solid angle of the detector from the supernova and so, such a det...

Answer A: how to scientifically explain this fictional type of matter?
I'm going to run through your list of points and see what happens: Fine. Has to interact via either gravity, strong or weak Fine. $0$ charge (no electromagnetic interaction), integer spin (are bosons). Think Higgs Boson, photons, gravitons etc. ('force-carriers'). "Neo Matter particles have the hal...

Answer A: What plausible things might happen in a *mildly* negative-entropic environment?
The second law of thermodynamics states that global entropy of an isolated system always increases or remains constant This tells us a couple of things that are relevant here: If the system is not interacting with anything, entropy cannot decrease. I.e. the entropy of the universe will never decre...

Answer A: Humans Achieve Massive Increase In Average IQs -- But How?
By definition, the average IQ score is 100. However, the above-mentioned Flynn effect states that average IQs relative to previous years' standards increases. Going by this paper, the increase in averaage IQ is about $2.9 \pm 0.3$ per decade (in the Stanford-Binet and Wechsler IQ tests) and also sug...

Answer A: What would define the "speed" (and direction?) of an alcubierre like warp drive?
Preamble Lets start from the beginning here. The Alcubierre drive is a result of general relativity. This has what's known as a metric. Minkowski spacetime (lets call this 'flat') has the metric $dS^2 = -dt^2 + dx^2 + dy^2 + dz^2$ (where the speed of light has been taken to be $1$). This leads to s...

Answer A: How to generate energy from recoil?
Using Michael Karnerfors' answer as a basis for the numbers, only instead of directly attaching the rail-gun to the ship so that everything moves as a whole, attaching the gun to a flywheel (or something similar), which is then connected to the ship so that only the gun moves (and the flywheel rotate...
