Once helium burning has occurred... the next possible reaction-carbon burning-is not necessarily slow... This reaction involves ...a strong as opposed to a weak interaction. ...Carbon burning results in magnesium. ...Taking a cross section of a highly evolved star would reveal a system of many layers. The inner layers have been subjected to the largest pressures, thereby forced to the highest temperatures, and burned the furthest; the outermost layers, by contrast, have not burned at all. Thus, as we proceed from outside in, there will be an outermost layer with the initial mix of hydrogen and helium, a layer of mostly helium, a layer of carbon, a layer of magnesium, and so on. ...So we arrive at the picture of a star, in the latest stages of its evolution... now composed of mostly carbon nuclei and other explosive material.
Frank Wilczek
Take a look at the simplest of objects. Let's take, for example, an old chair. It seems like nothing. But think of the universe comprised within it: the sweaty hands cutting the wood that used to be a robust tree, full of energy, in the middle of a luxuriant forest by some high mountains. The loving work that built it, the joyful anticipation of the one who bought it, the tired bodies it has helped, the pains and the joys it must have endured, whether in fancy halls or in a humble dining room in your neighbourhood. Everything, everything shares life and has its importance! Even the most worn down of chair carries inside the initial force of the sap climbing from the earth, out there in the forest, and will still be useful the day when, broken into kindling, it burns in some fireplace.
