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 ...

Almost 14 billion years ago, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of the infant universe and produced all known matter, according to the prevailing ...

The universe's expansion may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S ...

“Dark energy” is a term scientists use to refer to whatever is causing the universe to expand faster over time. We don’t know exactly what dark energy is—no one has ever directly seen or measured ...
