1 Gravity is fun!The word gravity, derived by Newton from the Latin gravitas, conveys both weight and deadly seriousness. But gravity can be the opposite of that. As I researched my book during the sleep-deprived days of the pandemic, flashbacks to the role gravity had played in some of my most memorable moments kept popping into my mind: swinging in hammocks in the Amazon, learning to fly over Niagara Falls, or simply letting myself go in the arms of loved ones.

Die physikalische Macht, die dahinter steckt, ist allerdings – Newton und Einstein hin oder her – längst noch nicht endgültig verstanden. Ein Gastbeitrag von Claudia de Rham Heute, 08:00 UhrGravitation ist ein vertrautes Konzept. Es ist in fast jeder Sprache und Kultur vertreten.

We present a formulation of ghost-free massive gravity with flat reference metric that exhibits the full nonlinear constraint algebraically, in a way that can be directly implemented for numerical simulations. Motivated by the presence of higher order operators in the low-energy effective description of massive gravity, we show how the inclusion of higher-order gradient (dissipative) terms leads to a well-posed formulation of its dynamics.
