The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

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 rested on a simple but audacious idea: that a fixed “cosmological constant” drives the universe’s accelerating expansion. Now a new wave of data is forcing ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and faster forever. Now a wave of new measurements suggests that this invisible ...

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

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 ...

Astronomy experiments could soon test an idea developed by Albert Einstein almost exactly a century ago, scientists say. Tests using advanced technology could resolve a longstanding puzzle over what ...

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 ...
