The start of the universe should be modeled not as a Big Bang but more like water freezing into ice, a team of theoretical physicists report. As reported in the journal Physical Review D, the researchers from the University of Melbourne and RMIT University suggest that by investigating the cracks and crevices common to all…
In 1967, the United States joined the United Kingdom and the Soviet Union in signing the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies. The agreement, more casually known as the “Outer Space Treaty,” remains the closest thing the world…
