What makes a kilogram a kilogram? Since the late 19th century the standard, which a kilogram has been measured, has been based on a chunk of platinum-alloy, called Le Grand K, that’s held at the International Bureau of Weights and Measures laboratory in Sèvres, France. According to the Encyclopedia Britannica, a kilogram was originally intended […]

Stephen Hawking: There May Be a Way Out of a Black Hole

August 26, 2015

Yesterday, renowned physicist and cosmologist Stephen Hawking, speaking to attendees of a conference being held at Sweden’s KTH Royal Institute of Technology, proposed a new idea that addresses a forty-year old cosmological mystery called the Black Hole Information Paradox. Simply put, the basis for the paradox is the conflict between quantum mechanics and the theory […]
