# What’s the Universe Made Of? Math, Says Scientist

MIT cosmologist Max Tegmark believes the universe is a mathematical structure. BROOKLYN, N.Y. — Scientists have long used mathematics to describe the physical properties of the universe. But what if the universe itself is math? That’s what cosmologist Max Tegmark believes. In Tegmark’s view, everything in the universe — humans included — is part of a mathematical structure. All matter is made up of particles, which have properties such as charge and spin, but these properties are purely mathematical, he says. And space itself has properties such as dimensions, but is still ultimately a mathematical structure. “If you accept the … Continue reading What’s the Universe Made Of? Math, Says Scientist
