Cosmology is already a complicated field of study, so switching up the variables is extra rough.

As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be ...

A remarkable new study challenges the findings of Nobel Prize winning research into how our universe has changed over time.
