Olberssches Paradoxon
Wie unterschiedlich schnell ein Ball aus 1km Höhe in unserem Sonnensystem fällt
Planetary scientist Dr. James O’Donoghue put together a fun video that compares how fast a ball drops onto 12 different surfaces in our solar system. For example, dropping a ball from .6 miles high and assuming no air resistance, it would take only 2.7 seconds to land on the Sun, 14.3 seconds to land on Earth, 15 seconds for Uranus, and a whopping 84.3 seconds for Ceres (a fine speed for us less nimble athletes).
