Talk:Big Bang

IMPORTANT: This is not the place to discuss how you think the universe began, or to discuss whether or not the Big Bang model is correct. This page is for discussing improvements to the article. The article is about the Big Bang model, with content based on information presented in peer-reviewed scientific literature about it or other appropriate sources. See Wikipedia:No original research and Wikipedia:Talk page guidelines. If you wish to discuss or debate the validity of the Big Bang, please do so at talk.origins.

Urgent help needed to fix 5 cosmology errors related to the Big Bang in the article Chronology of the universe

There are quite a few errors/ambiguities concerning Big Bang coverage in the related article Chronology of the universe. Some are actively misinforming readers. They need someone who can fix them.

Link: Talk:Chronology of the universe#Technical errors/ambiguities on the page, knowledgeable editing required to fix them

Big bang started as a result of quantum fluctuations of false vaccum

Can some one add about the beginning of big bang as a result of quantum fluctuations of metastable false vaccum. — Preceding unsigned comment added by 117.226.136.96 (talk) 08:04, 9 July 2018 (UTC)

Georges Lemaître

Hi everyone,

Big Bang Theory concept is from Georges Lemaître.

And I would like to add in the text :

"Georges Lemaître, a belgian catholic, first noted in 1927 that an expanding universe could be traced back in time to an originating single point, scientists have built on his idea of cosmic expansion. The scientific community was once divided between supporters of two different theories, the Big Bang and the Steady State theory, but a wide range of empirical evidence has strongly favored the Big Bang which is now universally accepted.

there is a 9 year made image of the univers that is color coded, yet there is no definition of the color codes. It is stated that the colors represent age, but what do the colors represent? The image is credited to NASA / WMAP Science Team. Please explain what colors mean. 67.40.125.146 (talk) 02:19, 18 July 2018 (UTC)

The colors show temperature. --Danski454 (talk) 12:20, 18 July 2018 (UTC)

 Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. Sir Joseph ^(talk) 19:54, 19 July 2018 (UTC)

Should there be a discussion of where the origination point is of the "big bang"?

I didn't find in the article the location of the origination point of the Big Bang. Is that an intolerable omission? (PeacePeace (talk) 04:03, 29 July 2018 (UTC))

It was everywhere, because there was nothing else. HiLo48 (talk) 04:05, 29 July 2018 (UTC)

Or, in other words, the location of the origin of the Big Bang is not discussed because a) it's hard to find the center of an expanding universe and b) good luck finding reputable and reliable sources discussing such a location.--Mr Fink (talk) 05:18, 29 July 2018 (UTC)

We could certainly discuss why there is no such point - it's a common question and I'm sure it's not hard to find reliable sources that discuss it. Waleswatcher (talk) 11:07, 29 July 2018 (UTC)

Flatness Problem

The Einstein-Cartan theory avoids the flatness problem as well as unphysical singularities. I believe this link needs be included in the Flatness Problem section. https://en.wikipedia.org/wiki/Einstein%E2%80%93Cartan_theory#Avoidance_of_singularities47.201.190.53 (talk) 19:26, 12 October 2018 (UTC)
