It s different

a new gravity map of the Earth suggests if you want to feel one per cent lighter you should be in India, where the pull of gravity is a bit less than elsewhere due to the type of mantle material beneath the country's crust.

The map, a colourful tapestry of space-based cartography, shows the little variations in the Earth's gravitational field depending on location. The amount of gravity in any point of the Earth is proportional to the amount of mass of that area. The more the mass, the stronger is its gravitational force.

The map is the first of many gravity maps to be generated by the twin satellites of grace
