Dark energy, the mysterious force driving the accelerated expansion of the universe, has puzzled scientists since its discovery in 1998. Despite its elusive nature, dark energy is believed to ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

Adam Riess takes us inside the discovery of dark energy. What does it feel like to make one of the biggest discoveries in physics? Adam Riess knows — because his work revealed that the universe isn’t ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda Cold Dark Matter, or ΛCDM, it weaves together dark energy, dark matter, and ...

The universe expands faster. “Dark energy” may not be constant after all. We’ve known since 1929 that the universe is expanding, and since 1998 that it’s speeding up. The unknown force behind this ...
