Quintessence: The Search for Missing Mass in the Universe is the fifth non-fiction book by the American theoretical physicist Lawrence M. Krauss. [1] The book was published by Basic Books on December 21, 2000. [2] [3] [4] This text is an update of his 1989 book The Fifth Essence.
In physics, Kaluza–Klein theory (KK theory) is a classical unified field theory of gravitation and electromagnetism built around the idea of a fifth dimension beyond the common 4D of space and time and considered an important precursor to string theory.
A five-dimensional space is a space with five dimensions. In mathematics , a sequence of N numbers can represent a location in an N -dimensional space . If interpreted physically, that is one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics .
[clarification needed] Similarly, modern quintessence would be the fifth known "dynamical, time-dependent, and spatially inhomogeneous" contribution to the overall mass–energy content of the universe. Of course, the other four components are not the ancient Greek classical elements, but rather "baryons, neutrinos, dark matter, [and] radiation."
The observation that matter occupies space goes back to antiquity. However, an explanation for why matter occupies space is recent, and is argued to be a result of the phenomenon described in the Pauli exclusion principle, [33] [34] which applies to fermions. Two particular examples where the exclusion principle clearly relates matter to the ...
The Fifth Essence: The Search for the Dark Matter in the Universe is the debut book by the American physicist Lawrence M. Krauss, published in 1989. [1] [2] Krauss talks about dark matter and its importance to our understanding of the universe. The book also contains information about modern astrophysics and Greek philosophers. [3]
Photonic matter is a phenomenon where photons interacting with a gas develop apparent mass, and can interact with each other, even forming photonic "molecules". The source of mass is the gas, which is massive. This is in contrast to photons moving in empty space, which have no rest mass, and cannot interact.
In the Big Bang, the expanding Universe causes matter to dilute over time, while in the Steady-State Theory, continued matter creation ensures that the density remains constant over time. In cosmology , the steady-state model or steady state theory is an alternative to the Big Bang theory.
