The cosmological constant will also cause a precession of the perihelion of a planet. Cardona and Tejeiro (, ApJ, , 52) claimed that this effect could set limits on the vacuum density only ten or so times higher than the critical density, but their calculation appears to be off by a .

It was a Nobel prize-winning discovery too. But these hopes were shattered with the discovery that the expansion of the universe is accelerating, which implied that the cosmological constant.

Einstein's Great Book of Universes. The arrival of Einstein's general theory of relativity marked a rebirth of interest and work in cosmology, the study of the universe on the largest scale. Within Newtonian theory, cosmology had reduced essentially to one question: just how is matter distributed within an infinite, Euclidean space. The Anthropic Principle is the Law of Human Existence. It is well known that our existence in this universe depends on numerous cosmological constants and parameters whose numerical values must fall within a very narrow range of values. If even a single variable were off, even slightly, we would not exist.

And the editors provide a series of introductions that describe the contributions of the papers and tie them together, making these classics more accessible Cited by: In cosmology, the cosmological constant (usually denoted by the Greek capital letter lambda: Λ) is the energy density of space, or vacuum energy, that arises in Albert Einstein's field equations of general is closely associated to the concepts of dark energy and quintessence.

Einstein originally introduced the concept in to counterbalance the effects of gravity and. The cosmological constant paradox Perhaps the most startling "cosmic coincidence" that modern scientists have noted in the structure of our universe is the fine-tuning of the cosmological constant [Vilenkin, pg.

The paradox derives from. The cosmological constant. You may have heard that the Universe's expansion is accelerating due to dark energy, and this requires yet one more parameter -- a Cosmological Constants book constant -- to describe.

The anthropic principle is a philosophical consideration that any data we collect about the universe is filtered by the fact that, in order for it to be observable in the first place, it must be compatible with the conscious and sapient life that observes it. Proponents of the anthropic principle reason that it explains why this universe has the age and the fundamental physical.

Cosmological constant, term reluctantly added by Albert Einstein to his equations of general relativity in order to obtain a solution to the equations that described a static universe, as he believed it to be at the constant has the effect of a repulsive force that acts against the gravitational attraction of matter in the universe.

When Einstein heard of the evidence that the. From the inside the front book cover flap: "Cosmological Constants gathers in one place the seminal works of such greats as Einstein, Hubble, Sakharov, Weinberg and Freidmann, much of which is hard to find or unavailable in English.

What is a Cosmological Constant. Einstein first proposed the cosmological constant (not to be confused with the Hubble Constant) usually symbolized by the greek letter "lambda" (Λ), as a mathematical fix to the theory of general its simplest form, general relativity predicted that the universe must either expand or contract.

1 The Cosmological Constant Problem A Classical Ambiguity In the eld equation for General Relativity, R 1 2 Rg + g = 8ˇGT ; () there is an ambiguity: the cosmological constant, is not xed by the structure of the theory.1 There is no formal reason to set it File Size: KB. Cosmological constant definition is - a constant term used in the relativistic equations for gravity to represent a repulsive force which may account in part for the rate of expansion of the universe.

For example, the cosmological constant may be a fundamental constant, but attempts have also been made to calculate it from other constants, and according to the author of one such calculation, "the small value of the cosmological constant is telling us that a remarkably precise and totally unexpected relation exists among all the parameters of.

The cosmological constant (, or also indicated by λ) is the value of the energy density of the vacuum of space. It was originally introduced by Albert Einstein in as an addition to his theory of general relativity to achieve a static cosmological constant is the simplest possible form of dark energy, since it is constant in both space and time.

The Cosmological Constant exists and the simplest solution (Occam’s Razor) is to admit that it exists to allow for carbon based life. Hence, it is a determined force with purpose, as opposed to an accidental force without purpose (which is mathematically absurd).

Seminal papers in cosmology are collected in this book. Included are Einstein's paper on cosmology and general relativity and the basic articles on the theoretical and observational foundations of the expanding universe.

The book also contains papers on the discovery of cosmic background radiation and the work leading up to it, and on the processes that occurred during Cited by: Exactly what the value of the cosmological constant is, though, is controversial.

There are different ways to measure the cosmological constant, and physicists have known for a few years that the Author: Starts With A Bang. Gravitation and Modern Cosmology The Cosmological Constants Problem.

Degree of fine tuning. Recent Studies have confirmed the fine tuning of the cosmological constant (also known as "dark energy"). This cosmological constant is a force that increases with the increasing size of the universe. First hypothesized by Albert Einstein, the cosmological constant was rejected by him, because of lack of real world data.
