I mean this is the Physics of things that everything takes energy. I have dealt elsewhere on my thoughts about money and the nonsense of the financial system in human affairs.
But I am fascinated by physical systems and how one thing feeds off another, a law that has worked its way into the realms of life as all life feeds off other life. It seems so central to our universe that we almost ignore it and take for granted the way in which reason can ameliorate an otherwise impersonal law like this. Preferring as we do to not think about it as it would take too much energy and bring about huge compromises in our own selfish behaviour to act in such a way as to limit what life dies so that we might continue to live.
As far as Physics is concerned though the earth is going to die and bits of our solar system one day may collide with others and set off a chain reaction that will develop a new sun. Without us dying that new sun may never be created. The idea of dying is different for living beings than it is for matter as a whole, or so it seems. But we have no idea if atoms can feel pain. Or even if that observation has any validity outside of sentient life. All we know is that atoms make up everything.
For all we know the universe is screaming in agony.
