A groundbreaking theory published in the Journal of Physics Communications suggests the universe may be 27 billion years old and does not require dark matter or dark energy to explain its behavior.
According to Dr. Farnes, the theory unifies dark matter and dark energy into a fluid with 'negative gravity,' which repels all other material around it.
The standard cosmological model known as LambdaCDM can only explain 5% of the observable universe, with the remaining 95% made up of dark matter and dark energy.
Farnes' theory may also prove right a prediction that Albert Einstein made 100 years ago, suggesting that Einstein himself predicted a negative-mass-filled universe.
The new theory also provides the first correct predictions of the behavior of dark matter halos, challenging the widely accepted ΛCDM model.
"Previous approaches to combining dark energy and dark matter have attempted to modify Einstein’s theory of general relativity, which has turned out to be incredibly challenging," Dr. Farnes said.
"The new approach takes two old ideas that are known to be compatible with Einstein’s theory — negative masses and matter creation — and combines them together," said a researcher.
"The study’s findings confirm that our previous work about the age of the universe being 26.7 billion years has allowed us to discover that the universe does not require dark matter to exist," explains Gupta.
What this adds
The theory challenges decades of cosmological beliefs and proposes an alternative explanation for the universe's behavior.
The theory does not require dark matter or dark energy, which have long been a cornerstone of modern cosmology.
The theory suggests that changes in fundamental constants and the effects of light losing energy over time can account for the same observations.
The theory stands in stark contrast to the widely accepted ΛCDM model, which has served as the standard cosmological framework for decades.

What's confirmed
- Farnes’ theory may also prove right a prediction that Albert Einstein made 100 years ago.
- The standard cosmological model known as LambdaCDM can only explain 5% of the observable Universe.
- “Previous approaches to combining dark energy and dark matter have attempted to modify Einstein’s theory of general relativity, which has turned out to be incredibly challenging,” Dr. Farnes said.
- The new theory also provides the first correct predictions of the behavior of dark matter halos.
- According to this theory, the constants of nature—such as the strength of electromagnetic forces or the speed of light—are not fixed across space and time.
- A groundbreaking theory proposes that the universe is 27 billion years old and doesn't require dark matter or dark energy, challenging decades of cosmological beliefs.
- The work, published in Journal of Physics Communications, reimagines gravity not as a force stitched into the fabric of spacetime, but as something that arises from the quantum-level behavior of ordinary matter.
- “The study’s findings confirm that our previous work (‘JWST early universe observations and ΛCDM cosmology’) about the age of the universe being 26.7 billion years has allowed us to discover that the universe does not require dark matter to exist,” explains Gupta.
- Instead of invoking invisible matter, Gupta’s model suggests that changes in fundamental constants and the effects of light losing energy over time can account for the same observations.
- Gupta’s study introduces an alternative explanation, questioning the very need for dark matter.
- According to Dr. Farnes, the theory unifies dark matter and dark energy into a fluid with 'negative gravity,' which repels all other material around it.
What's still developing
- In notes dating back to 1918, Einstein described his cosmological constant, writing that ‘a modification of the theory is required such that ‘empty space’ takes the role of gravitating negative masses which are distributed all over the interstellar space.’ It is therefore possible that Einstein himself predicted a negative-mass-filled Universe.
- The standard cosmological model failed to gain majority support, and no leading theory dominated the survey results.
- The largest survey ever conducted among physicists worldwide reveals surprisingly little agreement on some of the field’s biggest mysteries, including black holes, dark matter, and the unresolved effort to unite Einstein’s theory of gravity with quantum mechanics.

- SEPTEMBER 23 — When I think about the theory of multiverses, I wonder if there was an “other me” who didn’t survive the year.
- And that would mean that a ring-shaped black hole would, as scientists recently demonstrated, “break down” Einstein’s general theory of relativity. (And to think, the man was just coming off a phenomenal week.) In a study published in Physical Review Letters, researchers from the UK simulated a black hole in a “5D” universe shaped like a thin ring (which were first posited by theoretical physicists in 2002).
- “The better we get at simulating Einstein’s theory of gravity in higher dimensions, the easier it will be for us to help with advancing new computational techniques — we’re pushing the limits of what you can do on a computer when it comes to Einstein’s theory,” Tunyasuvunakool said.
- Most galaxies are rotating so rapidly they should be tearing themselves apart, which suggests that an invisible ‘halo’ of dark matter must be holding them together.
- These invisible components were thought to make up a significant portion of the cosmos, with dark matter alone accounting for 27% of the universe.
- Since the 1930s, when astronomer Fritz Zwicky first noted the unusual motion of galaxies in clusters, scientists have used dark matter to explain why galaxies spin faster than expected or why galaxy clusters behave in ways that seem inconsistent with their visible mass.
- Despite the lack of direct detection of dark matter, its existence has been inferred from gravitational lensing, galactic rotation curves, and other cosmic phenomena.
