More loosely, quintessence is the purest form of a particular substance. This is seen in the Hamlet soliloquy: "The beauty of the world, the paragon of animals and yet to me what is this quintessence of dust?"
In a new usage in physics, quintessence is a hypothetical form of energy postulated to exist as a possible explanation of observations of an accelerating universe. Quintessence is a type of vacuum energy defined as having an equation of state (relating its pressure pq and density q) of pq = wq. If , the quintessence acts as a repulsive field, pushing space apart, and it is this property which makes quintessence a possible candidate for dark energy. In general, the parameter w can vary with cosmological time, although some theorists refer to quintessence with a time-variable w as kinessence to distinguish it from more stolid forms of energy that have an equation of state in which w remains constant. Also, the term quintessence is generally not used to describe any hypothesised energy that has an equation of state in which . A non-zero cosmological constant can be seen as a special case where and does not vary in time. Another special case is phantom energyplease read carefuly for the sake of science. i am the one who made the theory of the fifth element become true and that was back in 1997. i can project my astral body wherever i want even outer space. theres an energie that comes out of my body the dark, in which .
