Researchers from UC Davis have proposed that dark energy may not be necessary to explain the universe's acceleration. They ...

Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the ...

For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is ...

Each of the 2,884 points in a dataset called Unite marks a star that blew apart. All are likely Type Ia supernovae, the kind ...

Comparing galaxy maps, supernovae and gravitational lensing shows why the case for changing dark energy depends on how ...

UT Austin theoretical astrophysicist Katherine Freese shares what we know (and don’t) about the invisible substance shaping ...

Igor Pikovski recently decided to tackle one of the holy grails of physics: discovering the quantum soul of gravity. "It’s ...

Dark energy is a ghostly force we know is pushing the universe apart, yet it doesn’t fit in our standard model of reality. Now some researchers think our universe might be pushing into a fifth ...

Mathematicians are raising a major challenge to one of modern cosmology's most widely accepted explanations: the idea that dark energy is driving the ...

The standard model of cosmology assumes dark energy never changes. It treats it as a constant that has pushed the Universe ...
