Why do some places on Earth have higher gravity than others? Sometimes the reason is unknown. To help better understand the Earth's surface, sensitive measurements by the orbiting satellites GRACE and CHAMP were used to create a map of Earth's gravitational field. Since a center for studying these data is in Potsdam, Germany, and since

    Look at that low US gravity, no wonder we’re so fat. And then there’s Australia and New Zealand over there breeding the next evolution of super humans.
    But most of all, wtf is going on in the Indian Ocean? Does shit just randomly launch into space sometimes?

    Maybe my eyes are gliding over it, but does anyone know what the actual difference is? They’ve got relative “+80” to “-80”, but no indication of what those units are. Would I be 1 kg lighter between the highest and lowest spot or .0001 grams lighter?

      Based on Wikipedia I think the unit is milligals, where a gal is 1 centimeter per second squared.

      That is a bit of an odd unit where g is ~980,000 milligals.

      So these changes are extremely small.

      So then the total variation is all within about 0.02% of gravities normal value

      The article says it’s “slightly different”, I imagine of a few grams, cuz a difference of 1kg between zones would be exaggerated.
