Contraction

There is, in my opinion , plasma which I see as a disorganized matter and, of course free energy and solid matter, geometrically stable and with energy which has very limited freedom! Each one can transform into the other one under certain circumstances! Which transformation would be called sucking in depends on the density of both! As I naively think that the solid one is denser, then the plasma transforms into solid and that's sucking in! So, the matter on the left side is being sucked into the matter with some certain geometrical forms on the right and it is the result of the sucking in! Contraction, that is!

I normally like to give you my ideas of what I see. However I am lost for words on this one. That said, I do like what I see. I think it is some mark of appeal of this image that it has attracted Pierre to write more than 3 or 4 words.
