The jury is out as to whether dark energy is best described by a cosmological constant or as dynamical. This Perspective presents both sides of the case and considers the questions that need to be ...

Unlike for dark matter, scientists have no plausible explanation for dark energy. According to one idea, dark energy is a ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.

If we find that gravity starts acting weird at the scale of a micron, it could trigger a process of discovery that could ...

A new study using the Dark Energy Survey (DES) final datasets suggests potential inconsistencies in the standard cosmological model, known as ΛCDM. If confirmed, these findings could fundamentally ...

The Fate of the Universe: Freeze or Rewind? Much of cosmology hinges on what will ultimately happen to our Universe. Since the 1930s, Edwin Hubble revealed that the cosmos is expanding. Going further, ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster. If the result ...

In an existing theory of gravity, the same present-day matter density can fit two very different histories of the universe.

The original version of this story appeared in Quanta Magazine. Physicists have deduced subtle hints that the mysterious “dark” energy that drives the universe to expand faster and faster may be ...

The Dark Energy Spectroscopic Instrument (DESI) collaboration just dropped their first official data release, covering the first 13 months of the instrument’s operation. While many conclusions were ...

An international collaboration of scientists has created the largest 3D map of our universe to date based on the first results from the Dark Energy Spectroscopic Instrument (DESI). It’s an impressive ...
