Study: Dark matter doesn't exist, the universe is 27B years old
A study by Rajendra Gupta proposes that dark matter and dark energy may not exist, suggesting the universe is about 27 billion years old, challenging conventional cosmological models and theories.

A new study by Rajendra Gupta from the University of Ottawa challenges the conventional understanding of the universe, proposing that dark matter and dark energy may not exist. Gupta's research combines two theories: covarying coupling constants (CCC) and "tired light" (TL). The CCC theory suggests that fundamental constants of nature may vary across the universe, while the TL model posits that light loses energy over vast distances, causing redshift without requiring an expanding universe. Gupta claims that these theories provide alternative explanations for cosmic phenomena, including the behavior of galaxies and the universe's age, which he estimates to be approximately 27 billion years, significantly older than the widely accepted 13.8 billion years. This research contradicts the standard cosmological model, which relies on dark matter to explain gravitational effects observed in galaxies. Critics argue that Gupta's model must produce testable predictions to gain acceptance, as current models are supported by extensive data. The study opens new avenues for cosmological research, prompting scientists to explore the implications of the CCC+TL model and its potential to reshape our understanding of the universe.
- Gupta's study suggests dark matter and dark energy may not exist.
- The universe is proposed to be approximately 27 billion years old.
- The CCC and TL theories offer alternative explanations for cosmic phenomena.
- The research challenges the widely accepted Big Bang theory.
- Further testing and validation of the CCC+TL model are needed.

Scientists may have found an answer to the mystery of dark matter
Scientists research dark matter, an invisible substance crucial for understanding the universe. Recent studies propose primordial black holes as a solution, suggesting they could account for dark matter and be detected by gravitational wave detectors.
The surprising behavior of black holes in an expanding universe
Physicist Nikodem Popławski's study reveals black hole behavior in an expanding universe. Einstein's equations suggest a constant expansion rate at black hole event horizons, challenging previous assumptions and shedding light on the Hubble tension. Popławski's work hints at a link between black holes, wormholes, and dark energy.
The universe had a secret life before the Big Bang, new study hints
A study suggests the universe may have contracted before the Big Bang, proposing dark matter consists of primordial black holes. Gravitational waves from this phase could be detected by future observatories.
Do we live in a shell universe?
Recent research introduces the "shell universe" model, proposing a thick shell of matter around a central void, potentially resolving Hubble tension and redefining cosmic evolution, but requiring further validation.
New research suggests that our universe has no dark matter
New research from the University of Ottawa suggests that dark matter may not exist, proposing that the universe's accelerated expansion results from weakening natural forces rather than dark energy, challenging conventional cosmological models.

It’s not a scientific theory unless it’s testable. I’m going to withhold judgement on this and take it for what it is: an interesting idea, and nothing more.
> We’ve always been taught that the fundamental constants of nature — like the speed of light or the charge of an electron — are unchanging. But what if they aren’t fixed after all?
I mean, sure, what if? Honestly, if you can vary things like gravity, I don't think you need any additional components to explain the dark matter observations.
> The CCC+TL model needs to provide testable predictions that can be confirmed or refuted through observations and experiments
This step is important!
Ok, so dark matter generally: this YouTuber [1](physicist/physics PhD) notes that there are many theories that explain the dark matter observations. But to her, "dark matter" is the data that we need to explain.
Essentially: we have a bunch of weird observations where it looks like there's way more matter than we see. But the actual explanation for what it is, there are tons of those. So throw one more in the pile (this one says "oh there's no extra matter, the universal constants are different over there and light maybe moves slower as it travels farther")
[ ] It cannot explain galaxy rotation curves across all galaxy types.
[ ] It fails to account for gravitational lensing observed in galaxy clusters.
[ ] It cannot explain the Bullet Cluster observations where dark matter appears separated from normal matter.
[ ] It is inconsistent with the cosmic microwave background anisotropies.
[ ] It cannot explain the large-scale structure and formation of the universe.
[ ] It introduces arbitrary parameters without physical justification.
[ ] It lacks a sound theoretical foundation or violates established physics principles.
[ ] It fails to explain the observed velocity dispersions in dwarf spheroidal galaxies.
[ ] It cannot account for empirical relations like the Tully-Fisher relation.
[ ] It cannot be tested or falsified by current or near-future experiments.
[ ] Your claims are unfounded or exaggerated.

I’m not a physicist, and cannot fill this in, but I thought I’d provide the template for the first physicist who turns up.
It seems dark matter and dark energy exist to balance deficiencies observed in our current understanding of particle physics applied to a cosmological model, particularly for observations that span vast distances extremely far away. From a purely logical perspective we should anticipate great deficiencies the further away we look because our entire understanding of the universe is derived from observations of various EMF transmissions only and only from Earth, or near Earth in the case of JWST. That is an exceptionally limited perspective. We have much to learn and more evidence to gather before conflating one avenue of science into a practice more akin to a religion.
"Spacetime" also does not exist. Time doesn't exist as a force of nature or tangible entity, it's nothing more than a subjective measurement. It exists like your height measurement exists, or the measurement of four meters of distance from you to the wall exists. The matter contained in the space of distance being measured exists, and the events between (subjective) time measurements existed, time itself does not exist. You can measure your height from the ceiling to your head (impractical but you can do it). You can measure time based on Mars going around the Sun. Neither entity exists (your height, nor time; both are subjective based on the anchor chosen). It would be silly to think height measurements are a tangible force of nature, we'll call it HeightSpace, now we must discover how it rules over the universe and seek to observe its magic principles.
The bogus nature of "spacetime" has held back multiple fields for many decades. It has wasted a generation of brains that fell for it.
