This awkward cosmic ingredient is forcing cosmologists to start over
Cosmology’s neat story of a universe driven apart by a simple, invisible “cosmic fuel” is starting to fray. A growing body of ...
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don’t explain the cosmic speed-up, they ...
New research suggests that these ultra-high energy rays derive their energy from magnetic turbulence. Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments -- like the ...
David Weinberg receives funding from the National Science Foundation and NASA that supports his dark energy research. Ashley Ross receives funding from Lawrence Berkeley National Lab to support his ...
When matter collides with antimatter, both vanish in a powerful energy burst. Scientists explain who truly wins this cosmic ...
Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...
