The paradox is that a static, infinitely old universe with an infinite number of stars distributed in an infinitely large space would be bright rather than dark. [1] A view of a square section of four concentric shells. To show this, we divide the universe into a series of concentric shells, 1 light year thick.
"Infinity turns out to be the opposite of what people say it is. It is not 'that which has nothing beyond itself' that is infinite, but 'that which always has something beyond itself'." (Aristotle) [5] Belief in the existence of the infinite comes mainly from five considerations: [6] From the nature of time – for it is infinite.
In his book, Greene discussed nine types of parallel universes: The quilted multiverse conditions in an infinite universe necessarily repeat across space, yielding parallel worlds. The inflationary multiverse says that eternal cosmological inflation yields an enormous network of bubble universes, of which our universe would be one.
In cosmology, a static universe (also referred to as stationary, infinite, static infinite or static eternal) is a cosmological model in which the universe is both spatially and temporally infinite, and space is neither expanding nor contracting. Such a universe does not have so-called spatial curvature; that is to say that it is 'flat' or ...
Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
The javelin argument, credited to Lucretius, is an ancient logical argument that the universe, or cosmological space, must be infinite. The javelin argument was used to support the Epicurean thesis about the universe. It was also constructed to counter the Aristotelian view that the universe is finite. [1]
In the 1996 edition of the book and subsequent editions, Hawking discusses the possibility of time travel and wormholes and explores the possibility of having a universe without a quantum singularity at the beginning of time. The 2017 edition of the book contained 12 chapters, whose contents are summarized below.
However, this is not implied by the abstract definition of a vector space, and vector spaces of infinite dimension can be considered. This is typically the case in functional analysis where function spaces are generally vector spaces of infinite dimension. In topology, some constructions can generate topological spaces of infinite dimension.
