It looks like you have a misconception about what the purpose of comments are. They aren't to have discussions, give "valuable information" etc. Anything worth value should be in an answer. Comments should be used to either ask for clarification from the OP or to give suggestions to improve the post. If they don't do this, then they shouldn't have ...

I didn’t delete the comment thread, but I’ve read the deleted comments. I don’t see any that should be restored because they add value to the question. The interesting back-and-forth was mostly on a tangentially related topic. I understand the purpose of the move-to-chat feature as a way to support an extended discussion about the question, not as a way to ...

A large proportion of these comments were made by users who have been repeatedly told not to have lengthy discussions in comments, and not to use comments in lieu of providing an answer where they can be properly downvoted if what they say is false. So I deleted them, since apparently moving to chat has so far not enticed these commenters to play by the ...

My 2p: When this comes up, people love to trot out the old "comments are transient" speech. They're right, of course. We should not hold any allusions that our comments should or will last for a protracted period of time, particularly if they start to venture slightly outside of the "requesting clarification" zone. But, if you start ...

The general rule of thumb is to that changes should make the post objectively better, while preserving its original intent. For example, while a massive block of all-caps text with no punctuation could arguably be called a stylistic choice, it is objectively harder to read than properly formatted text. On the other hand, things like adding two spaces after a ...

Chris has given you good general guidance. But in the interest of transparency: I declined your migration-request flag, partly because I'm not convinced the question would be on-topic at Engineering, and partly because you have already accepted an answer. Your question's upvoted answer should protect it from the roomba. My advice is that if you have ...

The first question is chock-full of technical jargon and it is about a fairly esoteric subject. It is not likely that there are many people who can adequately answer this question without first putting in copious effort to research it completely. Given that, it's unsurprising that there are no good answers because not many are going to look at it and find it ...

The $\ce$ command is provided by the mhchem package, which is available in MathJax but currently not loaded by default on Physics or Physics Meta. A workaround is to use $\require{mhchem}$ somewhere in the question or answer where you need it, e.g. $$\require{mhchem} \ce{np->d\gamma}$$ Note that, since 2019, statements like \require are local to ...

Except for a migration to Math SE, all migrations require the intervention of a moderator. If you are confident this question (or any other, as long as it is not $\ge$ 60 days old) is off-topic here but on-topic on another site, feel free to flag it for moderator attention with the flag button under the post. It is also possible to just post the question on ...

Yes, you lose reputation for downvoting answers (but not questions). See this post on the central meta for more discussion on this.

If you feel like two (or more!) answers deserve recognition, but you have only one green checkmark, you could reward the others with a bounty.

Some additional points: The reason those questions have not been answered is that the questions are hard. This shouldn't be so hard to understand, I hope. Those questions "are not active now" because... why would they need to be active at all? If a question on Stack Exchange has stood at high score for many years without getting answered: It ...

Yes, there is a large difference between questions which haven't been active for a while and closed questions. Closed questions are closed because for one reason or another they aren't a good fit for our site, and they cannot be answered unless they are reopened first. Older questions are just that - older - and can still be answered normally. If you see an ...

The requirements for that badge are five well-received questions, and a positive question record. You've fulfilled the first requirement, but not the second. You seem to be pretty close to even, so it shouldn't take many more well-received questions to fulfill that requirement, as long as you can avoid poorly-received questions.
