To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive ...

Results from the LUX-ZEPLIN experiment, co-founded by UC Santa Barbara physicists, mark a major step in defining what dark matter can and cannot be Determining the nature of dark matter, the invisible ...

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the universe's mass. While theoretical predictions hint at its abundance, detecting this ...

The mysterious force called Dark Energy, which drives the expansion of the Universe, might be changing in a way that challenges our current understanding of time and space, scientists have found. Some ...

This sensitivity opens an entirely new frontier: testing the existence of extremely light dark matter particles, with masses thousands of times smaller than those probed by previous experiments. In a ...

Fusion power has long been sold as the technology that could light our cities with the same process that powers the stars. Now a new line of research suggests those same reactors might also be ...
