Wrinkles left by the Big Bang may have magnetized the universe

As cosmic strings – exotic ripples in spacetime left behind by the first moments of the Big Bang – travel, they may trigger the formation of magnetic fields in their wake, new research suggests. These magnetic fields would then soak the universe, thus explaining the magnetization of galaxies and clusters, scientists propose in a new …

Popping Cosmic Inflation

Can cosmic inflation – and the Big Bang – be ruled out?

Cosmic inflation is a popular scenario for the first phase in the evolution of the Universe. Credit: A. Ijjas, PJ Steinhardt and A. Loeb (Scientific American, February 2017) According to astrophysicists, cosmic inflation – a point in the infancy of the Universe where spacetime expanded exponentially, and what physicists really refer to when they talk …
