Since liquid water is less dense than ice, under pressure the water can be in a lower energy state by being liquid instead of solid. This is why it can stay liquid at low temperatures. Also for the same reason the liquid water at the bottom of the lake can be in thermal equilibrium with the ice above so there does not have to be any energy input to drive the system.
So what's your number one complaint about hard drives: - Unreliable - Not enough space - Not fast enough - Too expensive - Makes too much noise - Generates too much heat - Is too damn thick!
On the other hand, there are the (relatively) recent measurements of distant galaxies moving faster than expected, suggesting a repulsive force weaker than gravity. If it does exist and is governed by some power law like gravity or electrical forces, then at sufficiently small distances it is stronger than gravity, thus creating an extremely powerful repulsive force.
The repulsive force measured actually increases with distance, not decreases like the gravitational or eletromagnetic forces, so the smaller the distance, the less powerful this force is.

Oops! Yeah I got that the wrong way around. :(
Thanks for the correction.
