3 Questions: Alan Guth on new insights into the ‘Big Bang’

…how the expansion was slowed by the attractive force of gravity. Inflation proposes that the expansion of the universe was driven by a repulsive form of gravity. According to Newton,…

Strong Gravity & Gravitational Radiation

advanced LIGO detectors, in concert with theoretical modeling of the waves that come from strong-gravity sources, will be a new and powerful probe of strong gravity and strong gravity systems….

Alan Guth shares $1 million Kavli Prize in Astrophysics

…Cosmological inflation builds on general relativity’s description of gravity as a distortion of space-time, which allows for the possibility of repulsive gravity. At very high energies, like those that existed…
