# Gravitational Waves and the Death of the PDF

Einstein published in 1916 a paper containing the prediction of the existence of gravitational waves. It has just one author (A.E. himself) and consists of a few pages of text and equations (Einstein, 1916). Fast forward exactly 100 years, the LIGO collaboration announced in a paper that they observed what Einstein had predicted. The paper has more than 1000 co-authors and it condenses, in just a few pages of text, equations and figures, an enormous amount of technical information (Abbott et al., 2016).
