Gravitational Surfing.

This article I'm about to write just completely blew me away!
Check this out. So we know every planet has to maintain a certain amount of gravity right? right! now because we know every planet more or less radiates gravity in this form:

Well because scientists know this they have been able to predict "gravitational surfs". "Gravitational surfs" or "tubes" if you will, are kind of like the Ocean's currents.

Which as you know it's easier to travel with a current than against it. Well this is exactly what NASA is trying to accomplish with these gravitational surfs and they have! Nasa launched the Genesis mission to explore solar winds, they used a small spacecraft to surf gravitational tubes on its way towards the Sun. The spacecraft only carried about 4% of its fuel as to the regular 40% and was a complete success.

The cool part is that these tubes will constantly shift with the motions of the planets because the tubes are formed between the “balancing points” (lagrange points) of two large gravitational bodies.

So what can be accomplished by this discovery is:
1) Interplanetary travel will be increased
2) Cheaper space travel: Less fuel is required to travel interplanetary.
3) Faster space travel; Like the discover of currents boosted trade and discovery in the days of old. This will have a similar impact. (:
