Hossenfelder is a freelance popular science writer who has kept a blog since 2006.[26] She contributes to the Forbes column "Starts with a Bang"[27] as well as Quanta Magazine,[28] New Scientist,[29] Nature Physics,[30] Scientific American,[31] Nautilus Quarterly[32] and Physics Today.[33] To show some gaps in the argument of Verlinde's claim that gravity is an entropic force, she derived[34] Verlinde's formula for Newton's law of universal gravitation using a new form of an entropic variation formula that reduces to Bekenstein-Hawking entropy at the black hole event horizon.
