I read TFA, and it specifically says that this is the matter that's causing the gravitational effects that were attributed to dark matter. To me, as a layman, that means that dark matter is no longer required to make things come out right. If you don't agree, please explain why, preferably with citations so that people like me can understand it.

I always expected that some day we'd find a way to detect the so-called dark matter, and that when we did, it would turn out to be ordinary matter rather than something incredibly exotic. The conventional description of dark matter as some weird particle that didn't interact with the rest of the universe in any way except the gravity produced by its mass just didn't sound plausible to me; rather than making me believe in it, that description pegged my BS meter. But I never argued against it because I had no evidence to support my position, just my gut feeling. Now, however, new evidence has been discovered that proves that I was right. I know that most people in my place would be gloating, but why? I'm just a layman with no detailed education in the subject who happened to get it right.

GLOAT!

If those former coal mines can be cleaned by Mother Nature in only 200 years, that's not bad at all. The Zone Rouge in northern France and Belgium has been cordoned off for a little over 100 years, and it's estimated that parts of it may need another 300-700 years to become habitable again.

I tried to follow that link you gave but alas, it's now 404 compliant.

Judging from the British new papers, I'm not surprised at all.

ROTFLMAO! Open mouth, insert foot.

Interesting. Back when I started college, everybody had to take the Subject A Exam before their first semester. This consisted of writing a short essay that would be read by a stranger. If that stranger could understand it and found the grammar and syntax acceptable, you passed and were expected to take Freshman English in your first semester. If not, you had to take Bonehead English, which was a remedial class and gave you no college credit. I wonder when that stopped.

Then setup your grammar checker.

You should take your own advice. The word "setup" is a noun, not a verb. Verbing it, the way you did here, should never be needed when all you need to do is split the word in half, producing "set up," which is a verb.

There was a time when Google let you use boolians to narrow your search results to those that you were most likely to want. Recently, they've removed that facility because it lowers the number of results and it's very important at Google to deliver as many results as possible, even though most of them are only vaguely related to what you asked for. The fact that Google doesn't care that this is a major regression says quite a bit about the company and it's ability to maintain its position when, not if, a competitor arises that includes boolians and brags that it produces the most useful results instead of simply the most.

Your average "snowflake" needs a civics lesson more than they need rifle training.

A few lessons in discipline wouldn't go amiss either. Interestingly enough, one of the easiest ways to teach large groups of people discipline in a short time is part of basic training in all branches: close order drill.

...because we're making a loss on this'-discount.

No, no, no! "At this price, I'm cutting me own throat!" Don't you know your Pratchett?

There are always going to be people who are willing to use violence to get what they want, including violence against the USA. Sometimes an all-volunteer military is enough to keep them at bay, and when that's the situation, snowflakes won't need to put themselves in harm's way to keep the rest of us safe. But there are times that that's not enough, and we need to build our forces up to a higher level than that can manage. When that happens, some of us will be picked to defend the rest of us regardless of what they want so that this nation can survive. That's why veterans get extra points in Civil Service exams, get subsidies to pursue their education and medical care for the rest of their lives: to repay us for our sacrifice. If you don't think that's appropriate, you must not think very much of your country.

If you really want to see Superman done right, find a copy of the Superman Serial produced by Columbia Pictures in 1948, and its sequel, Atom Man vs, Superman from 1950. They're the first two live action films about The Man of Steel, and the start of Noel Neill's "career" as Lois Lane.

If I had any PTSD, it's had over half a century to manifest itself so I think I managed to dodge that bullet. Still, my hearing loss (including tinitus) and diabetes took several decades to show up, so there still might be a surprise or two in my future.

Back in 1941, Warners got away with having Sam Spade call Wilmer a gunsel only because the censors didn't know what it means and thought it referred to a gunman.

Surely they make Flight Simulator part of the Copilot experience too.

No they don't, and don't call me Shirley!
