A groundbreaking cosmological theory is taking the scientific community by storm, suggesting that the universe did not originate from a single
Big Bang. Instead, this bold idea proposes that the cosmos has evolved through multiple, rapid bursts of energy known as
temporal singularities. In a
new paper published in Classical and Quantum Gravity, Dr.
Richard Lieu, a physics professor at The University of Alabama in Huntsville, introduces a fresh perspective on the universeâs expansion. According to Lieu, the cosmos is not the product of a
one-time Big Bang. Rather, it has grown through a series of ultra-fast, step-like bursts that release energy and matter across the entire universe.
Lieuâs model is a departure from conventional thinking. It challenges the widely accepted idea that
dark matterand
dark energy are responsible for the universeâs mysterious behaviors. Instead, Lieu proposes that these temporal singularitiesâunseen and untouchable by current observation techniquesâare the driving force behind cosmic evolution. One of the most exciting aspects of Lieuâs model is that it offers an explanation for the universeâs expansion without relying on dark matter or dark energyâtwo elusive concepts that have long been used to explain phenomena like cosmic acceleration. According to the physics professor, temporal singularities create whatâs known as
negative pressure, a type of energy density that causes the universe to expand at an accelerating rate.
In this model, the singularities fill the universe with energy and matter, yet because these bursts happen at such incredible speeds,
they are invisible to us. The theory suggests that the reason dark matter and dark energy have never been observed is that
they exist only during these bursts. Once the singularity fades, these forces vanish, leaving behind the galaxies and structures we see today. Lieuâs theory also dismisses the idea of exotic concepts like â
negative massâ or â
negative density,â which have been proposed in other cosmological models. Instead, he focuses on the idea that these rapid, recurring bursts of energy could provide all the necessary components for the universeâs expansion.
