Gravitational anomalies

Whilst researching on the internet about gravity I came across this fascinating map of our Earth.

The GRACE mission, a collaboration between NASA and the German Aerospace industry, ran between 2003-17. Twin satellites  mapped the Earth’s gravity field and charted its anomalies. They were looking at the quantity and movement of water. What they did find was that not only was the Earth not perfectly round, but  gravity varied globally.

Gravity was less strong in the blue patches, (mostly the oceans) and shaded to stronger towards the dark red/brown.( on first glance mostly mountain ranges. As before discussed, gravity does vary according to what it is traveling through. These models really bring that point to life though.

Aspects of reality

Gravity is not even as it travels though the Earth. It varies according to the terrain it passes through.
