Article milestones Date Process Result March 27, 2007 Good article nominee Not listed

This article failed good article nomination. This is how the article, as of March 27, 2007, compares against thesix good article criteria:

1. Well written?: Too confusing. The lead does not provide an adequate introduction of the topic; many details go unexplained.

2. Factually accurate?: Good.

3. Broad in coverage?: Could be longer; more information is needed on the topic, such as how a galactic tide originates and the history of its discovery.

4. Neutral point of view?: Good.

5. Article stability? Good.

6. Images?: Good.

When these issues are addressed, the article can beresubmitted for consideration. If you feel that this review is in error, feel free to take it to aGA review. Thank you for your work so far.

This article states "This causes the Earth to slightly flatten out as, on one side, its water is moved outward toward the Moon while on the opposite side, where the Moon's gravity is weakest, rotational force pulls water away from it, creating two "bulges"."

The article on Tidal Forces states "Tidal acceleration does not require rotation or orbiting bodies; e.g. the body may be freefalling in a straight line under the influence of a gravitational field while still being influenced by (changing) tidal acceleration"

and gives the subtraction of forces on the whole object from unequal forces on the circumference of an object as the reason for the pattern of tidal forces (and therefore "bulges")

I think the whole discussion of how Earth's tides work is misplaced here, and particularly so in the introduction. It's also an invitation to various incomplete or inaccurate attempts at description like the one mentioned above. If someone is interested ingalactic tides, they're unlikely to appreciate a long waffling-on about Earth-Moon tides right at the start. I have streamlined the introduction to this effect.Deuar11:43, 1 August 2007 (UTC)[reply]

If you look at the criteria listed for this article's failed GA nom, it's main (indeed only) issue was that it didn't explain enough to the lay reader. That expanded intro is an attempt to address that issue.Serendi^podous11:46, 1 August 2007 (UTC)[reply]

Drat. So much for an easy fix. Still, I think this stuff does not belong in the intro, maybe in a first section. What do you think?Deuar13:56, 1 August 2007 (UTC)[reply]

I'm not sure to be honest. My knowledge of tidal forces is fairly minimal, and I've been looking for information on it that I can understand. Problem is a lot of it seems contradictory.Serendi^podous13:58, 1 August 2007 (UTC)[reply]

Yes indeed, all the tidal stuff is easily and copiously mixed up.Deuar17:06, 1 August 2007 (UTC)[reply]

Some people claim that dark matter is stellar tides working together (here we speak about one galaxy), but it's 100% nonsense because we know from the bullet cluster that dark matter has inertia and at few cases may be separated for few million years from the galaxies. Even bullshit opinions should be mentioned but we must reveal that most don't agree for some reasons. Bullshit is the fertilizer of tomorrow!— Precedingunsigned comment added by2A02:587:4102:C400:1C37:1DD6:ABD3:AF6F (talk)17:33, 14 September 2016 (UTC)[reply]
