Review of revision 1080664 [Passed]Edit

1/4 or 3/4Edit

Our wiki article states that dark energy is 1/4 of our universe. This is likely due to confusion over matter/energy. I suggest a change for clarity.

Also, it is easy to find the original source. I do not believe that anyone at Nasa's Jet Propulsion Laboratory claimed that the "conclusion meant scientists could say for the first time that the expansion of the universe “will continue to accelerate and the universe will expand forever”." The news is that they have a new method. This article is defunct in my opinion. I write this here because I haven't taken the time required to fix it, so I am unsure about my claims.

3/4 is correct. The original Science article ( confirms current knowledge tha that Ωm (matter density, i.e. matter + dark matter) is about 0.25, the (dark) energy density is 1 - 0.25 (3/4).

I too am skeptical about the claim that NASA has said that the universe will expand forever. It is nowhere to be found on NASA's own website. I propose adding a statement to note this in the article. -- (talk) 09:41, 21 August 2010 (UTC)
I am also skeptical, but this is, what is presented. The article is supporting the ΛCDM model, which states, that universe is flat or slightly open, which means that it will continue to expand. Mykhal (talk) 16:01, 21 August 2010 (UTC)

Here are the quotes from the sources related to the first error.

BBC - "Dark energy makes up three-quarters of our Universe but is totally invisible. We only know it exists because of its effect on the expansion of the Universe."

Telegraph - "Almost a quarter, 24 per cent, is thought to be "dark matter", which is also mysterious but easier to study than dark energy because of its “gravitational influence”. The rest of the universe, a mere four per cent, is made of “the stuff that makes up people, planets, stars and everything made up of atoms”."

Yes! I propose a correction banner. In future, we should act more quickly when errors are noticed. --InfantGorilla (talk) 08:56, 22 August 2010 (UTC)
An IP seems to have added a proper correction banner, and it is currently pending. Does this look good to everyone else? red-thunder. 15:55, 22 August 2010 (UTC)
Looks fine to me. You can tell I wasn't completely awake when I wrote this article. Sorry for the confusion everybody! Tyrol5 (talk) 16:45, 22 August 2010 (UTC)

i also want to add that the process of light being "bent" by gravity is called "gravitational lensing" and not "gravitational lens" as stated in the article.
