Physicists at the University of Surrey have uncovered evidence suggesting that, at the quantum level, time does not have a single, forward direction but instead can emerge in two opposing directions.
An international team of energy scientists and theoretical physicists say they've solved the centuries-old mystery of why ultra-thin sheets of gold glow.
Scientists say they have created a new method of testing materials that allows predictions to be made about their strength, which may eventually lead to virtually “unbreakable” metals.
