New Theory Suggests That The Expansion Of The Universe May Not Be Real, Questioning Fundamental Concepts Of Cosmology And Raising Debates Among Scientists
A recent study challenges the idea that the universe is expanding. According to Lucas Lombriser, a professor at the University of Geneva, the apparent expansion may be an illusion caused by the variation of particle masses over time.
The idea was published in the journal Classical and Quantum Gravity and proposes a new explanation for dark matter and dark energy.
Questioning The Expansion Of The Universe
The idea that the universe is expanding comes from the redshift. When astronomers observe distant galaxies, the light emitted by them appears stretched to the red side of the spectrum.

This effect is interpreted as a sign that the galaxies are moving away. Furthermore, there is evidence that this expansion is accelerating, something described by the cosmological constant, known as lambda.
However, lambda represents a significant mystery for physicists. The value predicted by particle physics does not match observations, differing by 120 orders of magnitude. This problem has led the scientific community to seek answers for cosmic improvement.
Lombriser proposes a different path. Instead of suggesting new particles or forces, he revisits what is already known. He argues that the universe may be flat and static, as Albert Einstein believed.
In this model, the impression of cosmic expansion would be merely an effect of the masses of particles varying over time.
A New Look At Dark Matter And Dark Energy
Lombriser’s theory suggests that the masses of particles, such as electrons and protons, are not fixed. They change over time, influenced by a field that permeates spacetime.
If this is true, the cosmological constant would also vary, but due to this phenomenon, and not due to the expansion of the universe.
This approach could solve two of the greatest mysteries of modern physics: dark matter and dark energy. Dark matter accounts for 85% of the universe’s matter, but it does not emit light, making its detection extremely difficult.
Lombriser suggests that the fluctuations in the field that affect the masses of particles could behave like axions, one of the candidate particles for making up dark matter.
Furthermore, his theory eliminates the need for a mysterious force called dark energy, which would be responsible for the acceleration of the universe’s expansion. In Lombriser’s model, this prosperity is explained by the change in particle mass over time.
Despite the potential of the theory, the scientific community views the idea with caution. Testing this hypothesis is a challenge, as the changes in particle mass would be subtle and difficult to measure with current technologies.
Luz Ángela García, a researcher at the ECCI University, finds the proposal intriguing but emphasizes that proving this theory may take time. Still, Lombriser’s hypotheses open new possibilities for cosmology.
Even if his idea is not confirmed, it may inspire new approaches to solving the enigmas of the universe.
