A technical guide to one interacting dark-energy model: conservation equations, CMB scales and why normalizing density changes matter power. A linear-theory comparison, not a detection.

@hydezero-message.bsky.socialCan universes expand alike yet have different contents?
With a specified dark matter–dark energy exchange, models can match expansion but differ in light bending. An accessible guide to a theoretical comparison, not a detection.

@astro-dale.bsky.socialA useful thought to address Sunday night anxiety: A day on Venus is longer than its year. Venus takes 243 Earth days to rotate once, but only 225 Earth days to orbit the Sun. Imagine finally finishing a Monday and discovering it’s still Monday for another 242 days. #Perspective #Cosmology #Mondays
@jdyed.bsky.socialModern cosmology studies dark matter (binding galaxies) & dark energy (expanding the universe).
The Holy Quran described their mechanisms 1,400 years ago & settled the debate about what they are, as detailed in this image:

![This image says: What Does the Holy Quran State About "Dark Matter" and "Dark Energy"?
In cosmology, "dark matter" and "dark energy" are named as such not because they are truly dark, but because they are invisible—undetectable by instruments, light, radiation, and so forth—and because they are unseen, their true nature remains unknown to non-Muslims. "Dark matter" exerts a gravitational pull that keeps celestial bodies in their orbits, whereas "dark energy" drives the expansion of the universe. c
However, when the educated Sunni Muslim knows about the actions and effects of "dark matter", he remembers that God has said in Arabic in the Holy Quran 35:41: "Indeed, God holds the heavens and Earth from shifting [out of their proper positions], and if they were to shift, no one could hold them after Him". c
As for "dark energy", it reminds him that God has said in the Quran 51:47: "And the universe I built with Hands, and indeed I am expanding it".

@chrissbiblenewsletter.orgI find the cosmological argument compelling; it claims that everything that begins to exist has a cause, leading to the idea of an uncaused first cause behind the universe. #Cosmology #Philosophy
