In physics, quintessence is a hypothetical form of dark energy postulated as an explanation of observations of an accelerating universe. Quintessence is a scalar field which has an equation of state (relating its pressure pq and density ρq) of pq = wρq, where w is less than -1/3. Quintessence is dynamic, and generally has a density and equation of state that varies through time and space. By contrast, a cosmological constant is static, with a fixed energy density and w = −1. A black hole concept drawing by NASA. Physics (from the Greek, φυσικός (physikos), natural, and φÏσις (physis), nature) is the science of the natural world dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. ... A hypothesis (foundation from ancient Greek hupothesis where hupo = under and thesis = ) is a proposed explanation for a phenomenon. ... In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure. ... Accelerating universe is a term for the idea that our universe is undergoing divergent rapid expansion. ... In mathematics and physics, a scalar field associates a scalar to every point in space. ... In cosmology, the equation of state of a perfect fluid is characterized by a dimensionless number w, equal to the ratio of its pressure p to its energy density ρ: . It is closely related to the thermodynamic equation of state and ideal gas law. ...
Many models of quintessence have a tracker behavior, which partly solves the cosmological constant problem. In these models, the quintessence field has a density which closely tracks (but is less than) the radiation density until matter-radiation equality, which triggers quintessence to start behaving as dark energy, eventually dominating the universe. This naturally sets the low scale of the dark energy. The cosmological constant (usually denoted by the Greek capital letter lambda: Λ) occurs in Einsteins theory of general relativity. ... According to the Big Bang theory, the Universe originated in an extremely dense and hot state (bottom). ... In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure. ... In physics, energy scale is a particular value of energy determined with the precision of one order (or a few orders) of magnitude. ... In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure. ...
Some special cases of quintessence are phantom energy, in which w < −1 and k-essence (short for kinetic quintessence) which has a non-standard form of kinetic energy. Phantom energy is a hypothetical form of dark energy with equation of state . ... Kinetic energy is energy that a body has as a result of its speed or energy of motion. ...

Dark Energy dominates the Universe (outreach poster from University of Bonn)
For quintessence, however, the gravitational force is repulsive, and this causes the expansion of the universe to accelerate.
Quintessence is a dynamic, time-evolving and spatially dependent form of energy with negative pressure sufficient to drive the accelerating expansion.
Quintessence, a sublime substance, may permeate the universe, marking an end to the epoch that saw the formation of stars and galaxies, and the beginning of an epoch of cosmic acceleration.
So the word quintessence has a direct relationship to the basis of the Bible using the 4 elements of earth, water, air, fire and then quintessence which spiritually would be the new mind or the Christ consciousness.
Quintessence is dynamic, and generally has a density and equation of state that varies through time and space.
Then the physics connection to Quintessence used by science to describe an invisible and untrackable power or force in the universe also equated with dark energy, dark matter, and phantom energy.
