Can Dark Matter and Dark Energy Unify the Expansion of the Universe?

AI Thread Summary
The discussion centers on a paper proposing a unification of dark matter and dark energy through quantum wave function collapse. It suggests that energy is continuously liberated from a fluctuating scalar field interacting with dark matter's wave function, which could explain the universe's expansion. The authors argue that this process yields the necessary dark energy during galaxy formation, with an equation of state approaching ω = -1, indicating accelerated expansion. However, some participants express skepticism about the paper's coherence and its connection to established cosmological models. Overall, the concept presents an intriguing but contentious approach to understanding cosmic expansion.

Unification of dark matter and dark energy via quantum wave function collapse
Authors: A. S. Majumdar, D. Home
Comments: 5 pages, RevTex

Dynamical wave function collapse models entail the continuous liberation of a specified rate of energy arising from the interaction of a fluctuating scalar field with the matter wave function. We consider the wave function collapse process for the constituents of dark matter in our universe. Beginning from a particular early era of the universe chosen from physical considerations, the rate of the associated energy liberation is integrated to yield the requisite magnitude of dark energy at the time of galaxy formation. Further, the equation of state for the liberated energy approaches $\omega \to -1$ asymptotically, providing a mechanism to generate the present acceleration of the universe.

I wasn't sure i should post this letter, as is based on, along with hundreds
of others, on non discovered particles, energies, but i am not the one to
judge, against my better judgement i like the basic idea.
 
I have to agree that the article is pretty cranky (despite involving citations to legitimate journals, equations that resemble real GR equations, relevant buzz words, and allegedly funding to produce the paper). In short, it is incoherent and doesn't really set out a theory in any way connected to the universe or an established model of it. Still no harm done.

Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
