Scientists know very little about the mysterious force dubbed “Dark Energy” that seems to be quickening the expansion of the universe but, according to LSU Physics and Astronomy Associate Professor ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Nearly a decade ago, astronomers discovered the surprising existence of dark energy-a mysterious force that pushes galaxies apart and accelerates the expansion of the universe. Also known as the ...

In the quest to decipher the evolution of the cosmos, no topic generates greater interest among scientists than "dark energy," the mysterious force that appears to be causing the universe to expand at ...

What is the universe made of? This question has driven astronomers for hundreds of years. For the past quarter of a century, scientists have believed “normal” stuff like atoms and molecules that make ...

But new studies suggest that one of his most famous ideas, the cosmological constant, may not be fixed after all. If true, it ...

Professor Lawrence Krauss, department head of physics at Case Western Reserve University, will give a talk at the University of Massachusetts tomorrow. The lecture is called “Einstein’s Biggest ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...
