I remember in my first chemistry lessons at high school my teacher told us about atomic properties of materials elastics and stiffness and what ever else. At one point he came up with an example of an (theoretical?)liquid that would even crawl out of its vessel to overcome differences in gravity, desiring to get to closest to the gravity well as possible and even overcoming obstacles by trying to achieve this. Back then the idea quiet fascinated me, fascinated me enough to think every few years about it again.
But today, my self being a hobby astro physician and having at least a layman understanding of how gravity works, I start questioning his statement. I can't really understand how a substance could gain that "information" to when it can get closer to the source of gravity by a ratio between energy required to overcome the obstacle to gain in range reduction to teh gravity source.
So my question is, what was the substance he was refering to? Does such a substance exist? And if so, how does it work?
