Why are dark matter and dark energy favoured over changes to our physical models? [closed]
I am instinctively skeptical of the existence of "dark matter" and "dark energy". Together, they strike me as being analogous to luminiferous aether -- something that was invented ...

Is Dark Energy Taking Over?
First question, trying to keep it simple 😃
Because it's constant it grows in magnitude as the universe expands, whereas normal matter does not? Is this accurate as far as we know?

Theoretically, is it feasible for the dark matter density to be constant and homogeneous, as dark energy is, and the two to be related?
I know that currently dark matter and dark energy are separate things, not related and one not deriving from the other. But if both are included in a generalized gravitation theory, the picture can ...

What is the evidence against a variable gravitational constant? [duplicate]
I understand that our main supporting evidence for dark matter is the anomalous speed of objects orbiting around the edges of distant galaxies. Is there a reason why dark matter solves this problem ...

What if dark matter/energy did not exist?
What if dark matter and dark energy did not exist and were only due to a misinterpretation of the red shift of light or a measurement bias?
What would be the implications/consequences?

How can black holes possibly drive accelerating expansion of the universe?
(Potentially too broad, but all my questions are related to the paper in question.)
Recently there was an article published in Astrophysical Journal Letters that claims black holes "contribute ...

+ spin Photons inside a right hand circularly polarized field with -spin photons outside of that field…”dark matter/energy”
As I understand it, If I am inside of a rh, circularly polarized EM field, there are only +spin photons inside the field: no -spin photons are admitted inside. The field inside serves to “filter” out -...

The slowing of expansion in the matter dominated era
On all the graphs of the inflation of the universe, the era dominated by matter is slowing the rate of expansion. With an intuitive explanation (for all you science communicators out there) could you ...

$\Lambda$CDM's observations and the universe's matter content
It's known that the current value of the universe's total density parameter $\Omega_0=1$.
According to the $\Lambda$CDM model, the current density parameter of baryonic matter $\Omega_P \sim 0.04$, ...

Am I wrong if I interpret dark matter just as a red herring to justify the shortcomings of the current theories? [duplicate]
Wikipedia defines
Dark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe.
And continues with
Various astrophysical observations – ...

Dark energy/dark matter erodes confidence in origin theories [closed]
My layman's understanding is that we believe we have a good understanding of the development of the universe after the instant of the Big Bang.
Also, I understand that we believe that about 95% of the ...

Could Dark Matter Be Fully or Partially Explained by Gravitational Waves?
This is something I have wondered for a long time and cannot see why it is not a possible solution. Basically, any motion of matter (Mass may be a more accurate description here) through space time ...

Have information bits a mass-energy equivalence? [closed]
Is it plausible (as some authors conjectured recently) that information is physical and that information bits are stored as a mass-energy equivalent in the universe, accounting for cosmic dark energy ...
