Physicists are building detectors so sensitive that they may succeed in unraveling one of the greatest mysteries in modern physics: the true nature of dark matter.

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 ...

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 ...

Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

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 ...

In this video I test if light can be black. I show you several experiments that show you cases of light that is black and ...
