quintessencia
- But, if quintessence is the answer, we still don't know what it is like, what it interacts with, or why it exists.
Examples
-
The recognition that the universe is dominated by dark energy suggests a new field—known as quintessence—that permeates all space.
Academic text (2004) -
A possible candidate for dark energy that avoids some of the fine-tuning problems associated with the cosmological constant is quintessence, a very low-energy field with a wavelength comparable to the size of the observable universe.
Academic text (2004) -
One would expect that a quintessence field f related to dark energy would still be evolving and that its continuing evolution in time and space would lead to Lorentz-violating effects.
Academic text (2004) -
An alternative view of this mysterious dark energy that calls it "quintessence" presumes a temporal variability that Einstein's cosmological constant would not possess.
Academic text (2003) -
In addition to its effect on the expansion of the universe, quintessence might also manifest itself through its possible interactions with matter and radiation (n2, n18).
Academic text (2004) -
If future searches for Lorentz invariance and time-dependent fundamental "constants" bring positive results, they may prove that the universe contains a long-wavelength degree of freedom and point toward the nature of quintessence.
Academic text (2004) -
Scientists have three possible dark energy candidates: quintessence, vacuum energy, and phantom energy.

Etymology
Quintessence in modern cosmology borrows the old Latin name quinta essentia, 'fifth essence'. Scientists chose the word because it suggests a hidden 'fifth' ingredient of the universe that could drive its expansion, so the term fits this idea of a mysterious form of dark energy.
