Talk:Location of Earth

Purpose
I created this table after I heard an author on NPR say that her literary agent didn't know the difference between the solar system, the galaxy, and the universe, and asked her to write a book on the subject (which she did). I looked at some of our articles, and as they were, I'm not sure they help all that much. It's difficult for individual articles to put this information in context, so I'm creating this template to help do that. -- Beland (talk) 04:42, 2 January 2008 (UTC)


 * Doesn't this replicate the function of Earth's location ? 76.66.196.139 (talk) 07:46, 16 September 2009 (UTC)

Speedy delete disputed
This template is the target of an "expand" link from Template:UniverseNavSmall. There might be a better way to present this information, but this is what I came up with for a rough draft. I'm open to suggestions. -- Beland (talk) 23:14, 19 February 2008 (UTC)


 * This appears to be an article masquerading as a template... Instead of a non-transcluded template, shouldn't this just be created as an article? 76.66.196.139 (talk) 07:46, 16 September 2009 (UTC)


 * Well, it's now a full fledged article... 76.66.197.30 (talk) 02:27, 4 October 2009 (UTC)

Tidy up.
I've just been doing some maintenance of this article. If anyone disagrees with my changes, please let me know, as I can and will defend them. Cheers. Frunk (talk) 10:58, 11 July 2008 (UTC)

now that this has been renamed, should the related UniverseNavSmall also be renamed, since there's no "big" one anymore. 76.66.197.30 (talk) 02:09, 4 October 2009 (UTC)
 * That template is unnecessary; it says exactly the same thing as Earth's location, which which is far prettier and less obstructive. I was, rather ironically, planning to nominate it for deletion. Serendi pod ous  10:21, 4 October 2009 (UTC)

But does it live up to the title?
This article is an excellent summary of the various levels and categories of space, as they relate to the earth, but I came to it hoping to learn whether earth is at the center or near the edge of the known universe, only to find that the question is not even addressed.

It would be useful to have it considered in the article, even if the answer is that we cannot know the answer.--71.242.167.95 (talk) 14:37, 24 January 2010 (UTC)
 * According to current theories in cosmology, the universe is homogeneous and isotropic, meaning that it has no "centre" and no "edge". Every point in the universe could be seen as the centre, just as every point on the surface of the Earth could be seen as the middle.  Serendi pod ous  16:01, 24 January 2010 (UTC)

table
it should also have a log scale for size. Nergaal (talk) 01:08, 6 October 2010 (UTC)
 * How should it be represented? Serendi pod ous  01:35, 6 October 2010 (UTC)
 * Log scale is added - column "(km, as a power of 10, Logarithmic scale)" Grillofrances (talk) 00:49, 14 March 2022 (UTC)

Earth's position in relation to the observable universe
If the observable universe is a sphere at the "edges" of which we see a younger version of the universe (photon decoupling, close to the big bang, etc). This would mean the Earth is at the centre of this "sphere" of a certain diameter. Finite or infinite it is then an actual sphere towards the edges of which the "structure" of what we see changes, or begins to change.

If this sphere which is bounded by the structure changes occuring at its outer edges has a certain definite diameter in lightyears, putting the Earth at the center is a little weird.

This should be addressed as it is a basic question regarding Earth's position in the Universe, and the article makes no mention of it. (I.e. that the changes in structure at the edges of the observable Universe are equidistant in all directions. Puts Earth in the middle of everything)
 * it says in the opener that astronomers usually place the Earth at the centre of the observable universe for convenience.  Serendi pod ous  14:51, 1 March 2011 (UTC)

Thanks, but nevermind, I get it now; the spherical "pocket" of the observable universe does not denote the entirety of the universe. It could just be like any bubble inside an aquarium, towards the edges of the bubble we see an older version of the "surroundings", but how big those surroundings are, i.e. How big the aquarium is is not known. And we are ofcourse precisely in the middle of our view bubble.

Where it gets interesting is if there are models that theorize about the relationship in terms of scale of the observable universe (our pocket) and the entire universe (the aquarium), because then perhaps one can deduce where our "bubble" is in relation to the centre of the aquarium.

Multiverse and scale of the Universe.
I feel that the multiverse should be added as it is a possibility and would impact cosmology.

In addition, I feel that this article could be part of a series of articles covering the scale of the Universe. — Preceding unsigned comment added by AHumanEditor (talk • contribs) 00:50, July 29, 2017 (UTC)
 * The multiverse is purely hypothetical. There is zero evidence for it. We mention the hypothetical possibility, but we don't need to include it in the table of Earth's position in the Universe. Meters (talk) 05:41, 29 July 2017 (UTC)

The result of the move request was: consensus to move the page to Location of Earth, per the discussion below. Dekimasu よ! 17:17, 29 April 2018 (UTC)

Earth's location in the Universe → Location of Earth – The formatting of the proposed title is better. 2601:183:101:58D0:6C85:D0F:8214:9B38 (talk) 21:17, 22 April 2018 (UTC)


 * Suggest Location of Earth - I agree removing the possessive form is more encyclopedic, but also "in the Universe" seems a bit redundant. -- Netoholic @ 23:12, 22 April 2018 (UTC)
 * I agree with you 100%. Should I change my proposal to Location of Earth instead? 2601:183:101:58D0:41:33D3:8C5F:5399 (talk) 23:54, 22 April 2018 (UTC)
 * If you like it better, you can edit the request above (two spots to change), or you can leave it and can wait for others to add their input. -- Netoholic @ 02:49, 23 April 2018 (UTC)
 * Support 'Location of Earth', which I will need to find the damn thing sometimes. Earth keeps going off on a tangent well on its own way, and I have to either catch up or latch onto it next time around. Thus this article is a goddess-send (factoid: godsend is one word and goddesssend isn't). Randy Kryn (talk) 17:29, 23 April 2018 (UTC)

Pisces-Cetus supercluster complex
This is an issue that needs to be resolved, but I don't know how to do it. Since the discovery of Laniakea, we haven't really confirmed whether it replaced the Pisces-Cetus supercluster complex or subsumed it. Problem is, most of the references to the "Pisces Cetus supercluster complex" are from decades ago (it was first proposed in the 1980s and no one uses the term "supercluster complex" any more) so any references to Laniakea are likely to ignore it completely.
