There’s been this picture going on of what the earth would look like without oceans, except it isn’t true. The picture is actually a map of the earth’s gravity. Blue is lower gravity, orange is higher. Guess which spot has the lowest gravity in the world, by far? It’s Sri Lanka.
What this image shows is the density of whatever is under the earth and how that affects gravity. Because our earth isn’t a uniform thing underneath. So apparently whatever is going on under Sri Lanka isn’t that dense.
These are actually few implications of this, however. The gravity difference, as you may have noticed, are imperceptible. They can only be detected by two satellites that can detect hair’s breadth changes between themselves. This wonderful looking map has few applications.
You could say that this makes Sri Lanka the idea candidate for a space elevator, but not really. Being near the equator and the adopted home of Arthur C. Clarke are good for that proposition, but you could say that Singapore might be better suited to actually do it.
As it is it’s just a cool map and a rare opportunity to say we’re #1. Fuck gravity!
