voids are approx size of superclusters, supervoids are approx size of walls... or so it seems? 70.51.11.219 ( talk) 08:06, 2 August 2008 (UTC)
A 1994 census lists a total of 27 supervoids with a distance of up to 740 Mpc. [1]

Mpc is a unit of distance so what does the h stand for in h-1Mpc and why should that still be a unit of distance? I am tempted to remove any occurrence of h-1 unless a definition is provided. —Preceding unsigned comment added by 90.195.11.112 ( talk) 11:25, 24 August 2009 (UTC)
Wonder if the voids have a black hole at their center. If that were true someone else would have thought of it and tried to check for any form of evidence. —Preceding unsigned comment added by 198.53.87.153 ( talk) 00:19, 10 September 2009 (UTC)
From SIMBAD: [2] - a list of voids in the SIMBAD database, so we can construct a proper list article. 76.66.196.139 ( talk) 01:29, 21 September 2009 (UTC)
Vuo added this: "Voids were formed by baryon acoustic oscillations" with no citation. Surely this is only a hypothesis and not an accepted fact. How should this statement be qualified? Graeme Bartlett ( talk) 08:21, 25 May 2011 (UTC)
This article only talks about what a void physically is and not about the history of a void. The history section could talk about how the idea of a void was first introduced by the atomists, turned down by Aristotle and then later accepted by Christaan Huygens and Evangelista Torricelli. I think adding this section would give the article more substance and make it more informational. What do you think? Chargerfan12 ( talk) 00:50, 24 May 2013 (UTC)
According to recent reports the local supervoid is much larger than previously thought and may be the largest known object in the universe. [1] 551 Mpc if my math is correct. Maybe this information should be added to this page or the list of voids?

I thought that images from this work might work in this article. I do not have time to look into this just now, so I thought that I would make a note here. Blue Rasberry (talk) 19:58, 10 October 2017 (UTC)
void: beyond the event horizon of this Universe and black holes where there is no space and no time. 2601:580:102:4DA8:D8CB:EB0A:EADC:FA44 ( talk) 15:34, 11 July 2019 (UTC)
The illustration of matter density in the article resembles detergent foam. With a foam all we see is the detergent but the main component (without which it could not exist) is the gas within each bubble or void. Is it possible that the voids are made of some form of dark matter exerting a force equivalent to negative gravity? Or, perhaps, they could be the home of a dark energy.
If we have some field or dark matter exerting a repulsive force on ordinary matter would we need massive dark matter at all? — Preceding unsigned comment added by Stan staveley ( talk • contribs) 17:18, 26 December 2020 (UTC)
calling things first, second, third class SHOULD technically be a descriptor of "well this is the first class of algorithms this is the second class, and so forth", but general english speech patterns have it that "first class " means BETTER than "second class" and "third class"
im pretty sure this article isn't trying to make a statement that any of those algorithms are somehow superior to the other 2600:6C47:A03F:C443:E534:BFCC:9963:7EBA ( talk) 15:16, 22 August 2023 (UTC)
