Richard Muller’s New Book Links Flow of Time With Big Bang

A simple question from his wife, “Does physics really allow people to travel back in time?” propelled Lab physicist Richard Muller on a quest to resolve a fundamental problem that had puzzled him throughout his 45-year career: Why does the arrow of time flow inexorably toward the future, constantly creating new “nows”? That quest resulted in his new book “Now: The Physics of Time.” More>

Construction of World’s Most Sensitive Dark Matter Detector Moves Forward

LUX-ZEPLIN, an ultrasensitive dark matter detector, has cleared a major approval milestone and is on track to begin its mile-deep hunt for theoretical particles known as WIMPs in 2020. WIMPs are among the top prospects for explaining dark matter, the unseen stuff that we have observed only through gravitational effects. More>
