DARK ENERGY VS BARYONIC MATTER. “We conclude (at least are led to speculate) that the “particles” constituting dark energy obey infinite statistics, rather than the familiar Fermi or Bose statistics. This is the over-riding difference between dark energy and conventional matter. Note that here it is the physical non-negativity requirement of entropy for a gravitational system that leads to this unexpected conclusion.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

MODEL PROBLEMS. “The standard cosmological model, ΛCDM, has been very successful. But aside from the fact that dark matter particles have not been (directly) detected, this model suffers some noticeable shortcomings, such as missing satellite problem, core/cusp problem, too-big-to-fail problem, to name just a few.” (ΛCDM = the standard cosmological model). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

FIXING THE MODEL. “These apparent shortcomings of ΛCDM motivated the author and his collaborators to construct the Modified Dark Matter (MDM), a phenomenological dark matter model inspired by the consideration of entropy and gravitation.” (ΛCDM = the standard cosmological model). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

GRAVITY AND DISORDER. “Entropy and gravitation come together in Jacobson’s idea of gravitational thermodynamics. Essentially Jacobson proposes that gravity is simply a consequence of disorder as quantified by entropy.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

TIGHTLY WOVEN. “In order to appreciate how important a role entropy and gravitation play, let us first summarize the crucial steps in Verlinde’s derivation of the canonical Newton’s laws.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

STONE VS WOOD. “Experienced stone carvers say they can listen to the block of stone and feel when it will split through the strain on the chisel, but wood carvers describe a still more active dialogue with their material. They have to learn the character of each type of wood and take account of its ‘likes’ and ‘dislikes’ in the way that it is worked.” https://lnkd.in/ekm789He View in LinkedIn

FRAGMENT FROM NATURE concerns the phenomenon of emergence. “The phrase “more is different” was coined by PW Anderson in 1972, and sums up emergent phenomena, which occur when things scale to large numbers and transition into complex systems with new laws, such as the behavior of bird flocking, fish shoals, ripples in sand; new properties appear which are not present in their constituent parts. https://medium.com/sfi-30-foundations-frontiers/emergence-a-unifying-theme-for-21st-century-science-4324ac0f951e#:~:text=Examples%20of%20emergent%20behavior%20are,and%20planets%2C%20the%20evolution%20of View in LinkedIn

EMERGENCE. “In philosophy, systems theory, science, and art, emergence occurs when an entity is observed to have properties its parts do not have on their own, properties or behaviors which emerge only when the parts interact in a wider whole. Emergence plays a central role in theories of integrative levels and of complex systems.” https://en.m.wikipedia.org/wiki/Emergence View in LinkedIn

A DEFINITION. Goldstein initially defined emergence as: "the arising of novel and coherent structures, patterns and properties during the process of self-organization in complex systems". (1999). https://en.m.wikipedia.org/wiki/Emergence View in LinkedIn
