Arthur T Knackerbracket has found the following story:

[...] Renowned astrophysicist and National Medal of Science awardee Vera Rubin passed away in Princeton N.J., the evening of December 25, 2016, at the age of 88. Rubin confirmed the existence of dark matter—the invisible material that makes up more than 90% of the mass of the universe. She was a retired staff astronomer at the Carnegie Institution's Department of Terrestrial Magnetism in Washington, D.C.

"Vera Rubin was a national treasure as an accomplished astronomer and a wonderful role model for young scientists," remarked Carnegie president Matthew Scott. "We are very saddened by this loss."

In the 1960s, Rubin's interest in how stars orbit their galactic centers led her and colleague Kent Ford to study the Andromeda galaxy, M31, a nearby spiral. The two scientists wanted to determine the distribution of mass in M31 by looking at the orbital speeds of stars and gas at varying distances from the galactic center. They expected the speeds to conform to Newtonian gravitational theory, whereby an object farther from its central mass orbits slower than those closer in. To their surprise, the scientists found that stars far from the center traveled as fast as those near the center.

After observing dozens more galaxies by the 1970s, Rubin and colleagues found that something other than the visible mass was responsible for the stars' motions. Each spiral galaxy is embedded in a "halo" of dark matter—material that does not emit light and extends beyond the optical galaxy. They found it contains 5 to 10 times as much mass as the luminous galaxy. As a result of Rubin's groundbreaking work, it has become apparent that more than 90% of the universe is composed of this invisible material. The first inkling that dark matter existed came in 1933 when Swiss astrophysicist Fritz Zwicky of Caltech proposed it. But it was not until Rubin's work that dark matter was confirmed.

Besides her remarkable scientific contributions, as noted by colleague Neta Bahcall of Princeton University: "Vera was an amazing scientist and an amazing human being.  A pioneering astronomer, the 'mother' of flat rotation curves and dark-matter, a champion of women in science, a mentor and role model to generations of astronomers."

    Look pal, most of us let the green site over shit like what you are pulling.

    Nobody has named you the emperor of Soylent, so turn it down a bit.

    I did not reply to your previous comment, whcih I found authoritarian (I giving jelizondo an hour!) out of courtesy.

    But now I see you have some stuff up your ass, so go have a shit and stop being an arse.

    What am I pulling again? Calling you on your stupid abusive bullshit? Fuck you pal.

    Then leave this site. We don't need fuckers that abuse the site, complain about when articles appear, don't appear, whatever. YOU had the power to submit something, but instead needed to inappropriately admonish the staff during an article about somebody else's death.

    I'm not acting like the emperor, but a fucking tour guide if anything. Explaining to your stupid fucking ass how the site works, how you can submit stories, etc.

    Fuck all you fucking whiners that don't step up to contribute to the site, but complain about it, wheeeeeeennnnn those very same contributions would eliminate your complaints.

    In other words, shut the fuck up you backseat driving mother fucker.

      This is how you know what edIII is saying is true. A person paid to edit a site like this would never tell you to go fuck yourself.

      This is a community built by volunteers. They react like any normal person would to jabs. In case critics on this incident have never volunteered for anything before, an all-volunteer endeavor is only as good as the will of the community to pitch in and, you know, volunteer.

      Step up and offer to fix any gaps in the community you perceive. Complaints without action are worth nothing. If you don't have 5 minutes to submit the story you feel is missing, then the most the volunteers can be expected to entertain is constructive criticism, delivered in the friendliest, gentlest manner possible.

      Apparently you believe that submitting stories is all there is. I see three components: submitting stories, posting comments and financial support.

      I object to your calling Soylentils “entitled mother fuckers” for not submitting stories, that reduces the level of conversation at Soylent to that of 4chan and insults those of us who post comments and provide financial support, which is two-thirds of Soylent.

      I object to your “admonishing” people. It is a curious choice of words, why not ask, request or appeal? That verb is used by someone in power talking to an underling.

      So get a grip. Get a life.

        Again, fuck you. Your complaint was unwarranted and stupid. You could submit the story. It was obviously important to you.

        Yes, you come off as an entitled mother fucker when you *specifically* complain about the lack of a story when you are very able to submit same story.

        Nothing you can say can erase the stupidity of your original post, and how baseless and offensive your attacks against SN were.

        Step up, or shut up.

          Fuck you too, you motherfucker!

          If that is the level of conversation you're used to, fine I can deal with cocksuckers like you all day.

          I'm too fucking old to be scared by childish foul language.

          Now go and take that giant cock off your ass.
