Researcher proposes first-time model that replaces dark energy and dark matter in explaining nature of the universe

No Big Bang? Groundbreaking New Theory Could Upend the Standard Model of Cosmology

The universe’s expansion may be driven by “transient temporal singularities”—rapid, invisible bursts of energy—rather than dark matter or dark energy, according to new research that challenges the widely accepted standard model of cosmology. The theory, proposed by Dr. Richard Lieu, a professor of physics at The University of Alabama in Huntsville (UAH), argues that the “steps” of these singularities offer a better explanation for the universe’s…

Researcher proposes first-time model that replaces dark energy and dark matter in explaining nature of the universe

Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a paper in the journal Classical and Quantum Gravity that proposes a universe built on steps of multiple singularities rather than the Big Bang alone to account for the expansion of the cosmos.

The Cosmic Horizon: What Lies Beyond the Observable Universe? - New Space Economy

Because the speed of light is finite, distant regions of the universe remain invisible. Beyond this boundary, regions exist that are causally disconnected from what can be observed. This raises fundamental questions about the nature and extent of the cosmos beyond the observable limit.

The Milky Way exists in a cosmic void that breaks the laws of cosmology

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the universe seems to be expanding faster than expected, throwing a wrench into long-standing cosmological theories. This problem, known as the Hubble tension, challenges the most widely accepted explanation of the universe’s structure and evolution—what’s called the Lambda Cold Dark Matter (ΛCDM) model, or ΛCDM. At first glanc…

A brand new map of the universe could challenge Einstein's theory of the cosmos

By Miles Gilroy, SciTech Deputy EditorEinstein’s greatest blunderOne of the greatest misconceptions in all of science is the idea that gravity is a force. Yes, Isaac Newton was wrong. I realise that contesting arguably the greatest scientist of all time as a mere undergrad is bold, but, fear not, I have Albert Einstein, one of the most robust cosmological theories of all time, and the entirety of the 21st century scientific community on my side.…

Higgs boson may be driving the Universe's expansion - Advanced Science News

Scientists assume that inflation was driven by hypothetical inflaton particles, which scientists think could be the Higgs boson. The post Higgs boson may be driving the Universe’s expansion appeared first on Advanced Science News.
