The lower horizontal axis is the axion mass, the upper horizontal axis is the microwave frequency corresponding to the mass, and the vertical axis is the coupling constant of axion-to-photon conversion. Both axes are in logarithm scales. CAPP-8TB indicates the range of mass reported in this study. CAST indicates experimental […]

Astronomers have gotten creative in trying to trace the elusive cosmic web, the large-scale backbone of the cosmos. Researchers turned to slime mold, a single-cell organism found on Earth, to help them build a map of the filaments in the local universe (within 500 million light-years from Earth) and find […]

A sub-atomic particle has been identified that could have formed the “dark matter” in the Universe during the Big Bang. Scientists shed light on mystery of dark matter. Scientists have identified a sub-atomic particle that could have formed the “dark matter” in the Universe during the Big Bang. Up to 80% […]

The universe is governed by four fundamental forces: gravity, electromagnetism, and the strong and weak nuclear forces. These forces drive the motion and behavior of everything we see around us. At least that’s what we think. But over the past several years there’s been increasing evidence of a fifth fundamental […]

Crews at the Sanford Underground Research Laboratory in Lead, South Dakota, begin to lower the LUX-ZEPLIN central detector. Its nearly mile-long descent down an elevator shaft, and its delivery to a research cavern where it will hunt for dark matter, were successfully carried out last week.
