Talk:Cosmological constant problem

Speculation

Its Possible that the vacuum effect is reduced as the dark matter effect on the possible variable of the quantum field theory is that the dark matter the main compustory of the universe has adverse effects and makes the quantum field theory irreverent to the collection of zero-point energy —Preceding unsigned comment added by Yaik9a (talk • contribs) 22:09, 10 July 2009 (UTC)

My Hypothesis is that E = M*C^2 should rule. So M - E =0 at the time just previous to the Big Bang: Zero point theorema. So the Energy at time of Big Bang is in the order of 10^120 J. There is a huge Energy Potential that is only released in special occassions like a Big Bang.

This energy is converted into Matter (max 5% of all Energy now). Energy that wasnt caught by Protons (nucleuses) became dark energy (70% of all Energy now) or in Dark Matter (ca. 25%). Dark energy leaves a very thin energy trail: which was measured by the Voyager.

comparison is wrong

"For instance, the statement "the universe consists of exactly one elementary particle" is closer to being true, by at least ten orders of magnitude, than the incorrect vacuum-catastrophe prediction."

Consider that the Standard Model of Cosmology assumes that the size of the universe is infinite. Thus, the statement must necessarily be changed to "the observable universe [...]" --213.144.3.86 (talk) 08:47, 25 September 2015 (UTC)

Article unclear

measured values of the vacuum energy density

There isn't enough detail in this phrase to give it a clear meaning. How are the measurements made? What effects would the vacuum point energy have that could be measured in a conventional way? Are the measurements lab measurements or astrophysical ones? 76.118.180.76 (talk) 17:07, 1 November 2015 (UTC)

Cosmological Constant Problem

I'm not an expert, but I'm thinking that the cosmological constant problem is the same issue as the vacuum catastrophe. If that's true, I recommend having cosmological constant problem redirect to this article.

Suggestions not mentioned here

1. there is a sort of equilibrium that cancels the excessive energy
2. an old dying universe reaches temperatures close to the absolute zero thus somehow that equilibrium breaks off — Preceding unsigned comment added by 2A02:587:4112:2300:D002:1EA0:421E:EE98 (talk) 00:47, 5 August 2016 (UTC)

There's probably nothing there

No vacuum, no fields, even space itself is not a thing to be measured because it's definitively not a thing. "space bends" when interactions happen and if there's nothing going on there is no void to fill either — Preceding unsigned comment added by 2601:449:8200:A430:483F:9DB0:E740:6D4F (talk) 03:31, 19 February 2018 (UTC)

Incorrect grammar

The following sentence in this article does not make grammatical sense: "Light front quantization is a rigorous alternative due to Paul Dirac to the usual second quantization method (instant-form method)." It appears that there should be additional words between "Dirac" and "to". Any ideas?

Would this make more sense?

(I'm just giving it a shot. I have some insight on the topic at hand, but not an expert, so bear with me.)

Light front quantization provides a rigorous alternate solution(/explanation?) to the cosmological constant problem. Given Paul Dirac's theory on the topic of the usual second quantization method (instant-form method). Rettetasten (talk) 21:32, 24 November 2018 (UTC)

Tagged Incomprehensible

Section has multiple grammatical problems combined with a highly technical subject matter explained like a research paper. Perhaps written by English second language author. Not currently suitable for encyclopedic reference. Tagged with incomprehensible because I didn't want to tag it with multiple tags. It needs to be thoroughly reworded by a specialized expert.

FYI, the IPs are socks of a community-banned user whose CV is found at WP:LTA/BKFIP. This article is one of his favorite obsessions so I have semi-protected it again, this time for three months. Favonian (talk) 10:34, 12 February 2019 (UTC)

Coming in from WikiProject Physics... I doubt the removed text actually belongs, especially at that length. It appears to be a legitimate proposal, but not one that has swept the field away, so spending that many words on it might be giving it undue weight. Without investigating the page history too deeply, I suspect it was significantly shaped by self-promotion. I was also mildly surprised to find some proposals missing, e.g., that of Bill Unruh and collaborators [1], or the idea that in unimodular gravity the troublesome contributions simply do not gravitate [2][3].

Here is a recent-ish review that might be helpful in overhauling the "proposed solutions" section. XOR'easter (talk) 20:45, 17 February 2019 (UTC)

I did a quick re-write to address due-weight concerns. XOR'easter (talk) 21:09, 17 February 2019 (UTC)
