Remove ball lightning from the list?[edit]

Recently ball lightning has been observed and had its spectra analyzed for the first time. It's caused by silicon in the soil being vaporized and subsequently oxidized. 1 So shall we move this to recently solved problems? ScienceApe (talk) 06:55, 24 January 2014 (UTC)

I'm not convinced ball lightning is or was a problem of physics to begin with; more like a problem of meteorology. Was the tornado a problem of physics before science figured it out? -Jordgette [talk] 01:44, 25 January 2014 (UTC)
It was a problem because it was so infrequent and relied upon anecdotes for the majority of its evidence. Before the recent study and spectral analysis, many physicists even denied it existed at all due to their transient and rare occurrences. Tornadoes weren't a problem in the same sense because no one was skeptical of their existence, people knew they existed because they are kinda hard to miss.

Indirect Detection of Gravitational Waves[edit]

I have deleted the entry claiming that gravitational waves have been directly detected for the first time, as this is untrue. BICEP2 did not directly detect gravitational waves; it measured their influence on CMB polarization. The only prospect of a direct detection of gravitational waves is through interferometric methods, e.g. LIGO. Journalists this week are really skewering the science, but The Guardian gets it more right than "I Fucking Love Science", which is what was referenced for that claim.

Red links[edit]

We have some redlinks in this article which should be fixed or at least reviewed. RJFJR (talk) 02:39, 9 June 2014 (UTC)

Dwarf galaxy problem[edit]

Should it be included? Paradoctor (talk) 23:10, 26 July 2014 (UTC)

The dwarf galaxy problem is really one particular problem with some versions of Cold Dark Matter theory, rather than a problem related to dwarf galaxies per se.Ohwilleke (talk) 02:10, 29 August 2014 (UTC)

Planar Galactic spheroid[edit]

See this edit. I think think this merits inclusion as soon as the relevant content is in shape. Paradoctor (talk) 23:25, 26 July 2014 (UTC)

Remove quasars from the Solved list?[edit]

The article says that quasars are now generally understood. Yes, the current view is that they are galactic cores where the enormous energy output results from matter falling into a massive black hole in the center of the galaxy. However, observations show that they can vary their light output daily, suggesting a quasar diameter constrained by a light-day's distance, and that would limit their radius to just more than four times the distance of the Sun to Pluto, far to miniscule to represent a galactic core. Perhaps healthy scientific skepticism would keep quasars, for now, off the Solved list. Thoughts?
