Special Issue Information
Dear Colleagues,
The concordance ɅCDM model has been successful in accounting for much of our known universe. However, the model fails to account for some features, such as the Hubble tension and the σ8 fluctuation parameter tension, features that emerged recently as observational accuracy improved. As the required value of the cosmological constant is still without a satisfactory physical explanation and as cold dark matter particles have yet to be detected, we should consider other possible contributions to the universe energy budget. Landauer’s Principle provides us with an equivalent energy for each bit of entropy/information in the universe. This equivalent energy should be taken into account alongside Einstein’s mc2 equivalent energy of matter. The aim of this Special Issue is to collect works which consider the role that information energy can play as a source of dark energy, and also any possible role of information energy in explaining features previously attributed to dark matter.
Subjects of interest include but are not limited to:
- Landauer’s Principle, information–energy equivalence;
- Information content of the universe, total information energy in the universe;
- Astrophysical and cosmological entropy;
- Information energy as dark energy;
- Holographic dark energy models;
- Comparison of information models with observational data;
- Information equation of state parameter and universe expansion;
- Information energy as a solution to tensions and problems of ɅCDM;
- Can the universe information energy distribution explain H0 directional anisotropies?
- Does the information energy distribution within galaxies coincide with dark matter attributed effects?
- Information energy predicted experimental observation signatures for model falsification.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
