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.
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 ...
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the " fundamental sciences " because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics.
The physical universe is defined as all of space and time [a] (collectively referred to as spacetime) and their contents. [10] Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space.
In his 1687 theory, Isaac Newton postulated space as an infinite and unalterable physical structure existing before, within, and around all objects while their states and relations unfold at a constant pace everywhere, thus absolute space and time. Inferring that all objects bearing mass approach at a constant rate, but collide by impact ...
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 .
