'''Radiation resistance''' is that part of an [[antenna (electronics)|antenna]]'s feedpoint resistance that is caused by the [[radiation]] of [[Electromagnetic radiation|electromagnetic]] waves from the antenna, as opposed to loss resistance (also called ohmic resistance) which generally causes the antenna to heat up. The total of radiation resistance and loss resistance is the [[electrical resistance]] of the antenna.

The radiation resistance is determined by the geometry of the antenna, where loss resistance is primarily determined by the materials of which it is made.  While the energy lost by ohmic resistance is converted to heat, the energy lost by radiation resistance is converted to electromagnetic radiation.
== General metric ==


Radiation resistance is caused by the [[radiation reaction]] of the conduction electrons in the antenna.
The FLRW metric starts with the assumption of [[homogeneity (physics)#Translation invariance|homogeneity]] and [[isotropy]] of space. It also assumes that the spatial component of the metric can be time-dependent. The generic metric which meets these conditions is
:<math>- c^2 \mathrm{d}\tau^2 = - c^2 \mathrm{d}t^2 + {a(t)}^2 \mathrm{d}\mathbf{\Sigma}^2</math>
where <math>\mathbf{\Sigma}</math> ranges over a 3-dimensional space of uniform curvature, that is, [[elliptical space]], [[Euclidean space]], or [[hyperbolic space]]. It is normally written as a function of three spatial coordinates, but there are several conventions for doing so, detailed below. <math>\mathrm{d}\mathbf{\Sigma}</math> does not depend on ''t'' — all of the time dependence is in the function ''a''(''t''), known as the "[[Scale factor (universe)|scale factor]]".


When electrons are accelerated, as occurs when an AC electrical field is impressed on an antenna, they will radiate electromagnetic waves. These waves carry energy that is taken from the electrons. The loss of energy of the electrons appears as an effective resistance to the movement of the electrons, analogous to the ohmic resistance caused by scattering of the electrons in the crystal lattice of the metallic conductor.
===Reduced-circumference polar coordinates===
In reduced-circumference polar coordinates the spatial metric has the form
:<math>\mathrm{d}\mathbf{\Sigma}^2 = \frac{\mathrm{d}r^2}{1-k r^2} + r^2 \mathrm{d}\mathbf{\Omega}^2, \quad \text{where } \mathrm{d}\mathbf{\Omega}^2 = \mathrm{d}\theta^2 + \sin^2 \theta \, \mathrm{d}\phi^2.</math>


[[Power (physics)|Power]] is calculated as
''k'' is a constant representing the curvature of the space. There are two common unit conventions:
*''k'' may be taken to have units of length<sup>−2</sup>, in which case ''r'' has units of length and ''a''(''t'') is unitless. ''k'' is then the [[Gaussian curvature]] of the space at the time when ''a''(''t'') = 1. ''r'' is sometimes called the reduced [[circumference]] because it is equal to the measured circumference of a circle (at that value of ''r''), centered at the origin, divided by 2{{pi}} (like the ''r'' of [[Schwarzschild coordinates]]). Where appropriate, ''a''(''t'') is often chosen to equal 1 in the present cosmological era, so that <math>\mathrm{d}\mathbf{\Sigma}</math> measures [[comoving distance]].
*Alternatively, ''k'' may be taken to belong to the set {−1,0,+1} (for negative, zero, and positive curvature respectively). Then ''r'' is unitless and ''a''(''t'') has units of length. When ''k'' = ±1, ''a''(''t'') is the [[Radius of curvature (mathematics)|radius of curvature]] of the space, and may also be written ''R''(''t'').


:<math>P = I^2R \,</math>
A disadvantage of reduced circumference coordinates is that they cover only half of the 3-sphere in the case of positive curvature—circumferences beyond that point begin to decrease, leading to degeneracy. (This is not a problem if space is [[elliptical geometry|elliptical]], i.e. a 3-sphere with opposite points identified.)


where <math>I</math> is the [[electric current]] flowing into the feeds of the antenna and <math>P</math> is the power in the resulting electromagnetic field. The result is a virtual, effective [[Electrical resistance|resistance]]:
===Hyperspherical coordinates===
In ''hyperspherical'' or ''curvature-normalized'' coordinates the coordinate ''r'' is proportional to radial distance; this gives
:<math>\mathrm{d}\mathbf{\Sigma}^2 = \mathrm{d}r^2 + S_k(r)^2 \, \mathrm{d}\mathbf{\Omega}^2</math>
where <math>\mathrm{d}\mathbf{\Omega}</math> is as before and
:<math>S_k(r) =
\begin{cases}
\sqrt{k}^{\,-1} \sin (r \sqrt{k}), &k > 0 \\
r, &k = 0 \\
\sqrt{|k|}^{\,-1} \sinh (r \sqrt{|k|}), &k < 0.
\end{cases}
</math>


:<math>R = \frac{P}{I^2} \,</math>
As before, there are two common unit conventions:
 
*''k'' may be taken to have units of length<sup>−2</sup>, in which case ''r'' has units of length and ''a''(''t'' ) is unitless.  ''k'' is then the [[Gaussian curvature]] of the space at the time when ''a''(''t'' ) = 1.  Where appropriate, ''a''(''t'' ) is often chosen to equal 1 in the present cosmological era, so that <math>\mathrm{d}\mathbf{\Sigma}</math> measures [[comoving distance]].
This effective resistance is called the '''radiation''' resistance.
*Alternatively, as before, ''k'' may be taken to belong to the set {−1,0,+1} (for negative, zero, and positive curvature respectively). Then ''r'' is unitless and ''a''(''t'' ) has units of length. When ''k'' = ±1, ''a''(''t'' ) is the [[Radius of curvature (mathematics)|radius of curvature]] of the space, and may also be written ''R''(''t'' ).  Note that, when ''k'' = +1, ''r'' is essentially a third angle along with ''θ'' and ''φ''. The letter ''χ'' may be used instead of&nbsp;''r''.


==See also==
Though it is usually defined piecewise as above, ''S'' is an [[analytic function]] of both ''k'' and ''r''. It can also be written as a [[power series]]
*[[Abraham–Lorentz force]]
:<math>S_k(r) = \sum_{n=0}^\infty \frac{(-1)^n k^n r^{2n+1}}{(2n+1)!} = r - \frac{k r^3}{6} + \frac{k^2 r^5}{120} - \cdots</math>
*[[Impedance of free space]]
or as
*[[Bremsstrahlung]]
:<math>S_k(r) = r \; \mathrm{sinc} \, (r \sqrt{k})</math>
where sinc is the unnormalized [[sinc function]] and <math>\sqrt{k}</math> is one of the imaginary, zero or real square roots of ''k''. These definitions are valid for all ''k''.

===Cartesian coordinates===
When ''k'' = 0 one may write simply
:<math>\mathrm{d}\mathbf{\Sigma}^2 = \mathrm{d}x^2 + \mathrm{d}y^2 + \mathrm{d}z^2.</math>
This can be extended to ''k'' ≠ 0 by defining
:<math> x = r \cos \theta \,</math>,
:<math> y = r \sin \theta \cos \phi \,</math>, and
:<math> z = r \sin \theta \sin \phi \,</math>,
where ''r'' is one of the radial coordinates defined above, but this is rare.
 
== Solutions ==

{{main|Friedmann equations}}
 
Einstein's field equations are not used in deriving the general form for the metric: it follows from the geometric properties of homogeneity and isotropy. However, determining the time evolution of <math>a(t)</math> does require Einstein's field equations together with a way of calculating the density, <math>\rho (t),</math> such as a [[equation of state (cosmology)|cosmological equation of state]].
 
This metric has an analytic solution to [[Einstein field equations|Einstein's field equations]] <math>G_{\mu\nu} + \Lambda g_{\mu\nu} = \frac{8\pi G}{c^{4}} T_{\mu\nu}</math> giving the [[Friedmann equations]] when the [[energy-momentum tensor]] is similarly assumed to be isotropic and homogeneous. The resulting equations are:<ref>{{citation |author=P. Ojeda and H. Rosu |date=2006 |title=Supersymmetry of FRW barotropic cosmologies |journal=[[International Journal of Theoretical Physics]] |volume=45 |issue=6 |pages=1191–1196 |doi=10.1007/s10773-006-9123-2 |arxiv=gr-qc/0510004 |bibcode=2006IJTP...45.1152R}}</ref>
:<math>\left(\frac{\dot a}{a}\right)^{2} + \frac{kc^{2}}{a^2} - \frac{\Lambda c^{2}}{3} = \frac{8\pi G}{3}\rho</math>
:<math>2\frac{\ddot a}{a} + \left(\frac{\dot a}{a}\right)^{2} + \frac{kc^{2}}{a^2} - \Lambda c^{2} = -\frac{8\pi G}{c^{2}} p.</math>
 
These equations are the basis of the standard [[big bang]] cosmological model including the current [[Lambda-CDM model|ΛCDM]] model. Because the FLRW model assumes homogeneity, some popular accounts mistakenly assert that the big bang model cannot account for the observed lumpiness of the universe. In a strictly FLRW model, there are no clusters of galaxies, stars or people, since these are objects much denser than a typical part of the universe. Nonetheless, the FLRW model is used as a first approximation for the evolution of the real, lumpy universe because it is simple to calculate, and models which calculate the lumpiness in the universe are added onto the FLRW models as extensions. Most cosmologists agree that the [[observable universe]] is well approximated by an ''almost FLRW model'', i.e., a model which follows the FLRW metric apart from [[primordial fluctuations|primordial density fluctuations]]. {{As of|2003}}, the theoretical implications of the various extensions to the FLRW model appear to be well understood, and the goal is to make these consistent with observations from [[Cosmic Background Explorer|COBE]] and [[WMAP]].
 
===Interpretation===
The pair of equations given above is equivalent to the following pair of equations
:<math>{\dot \rho} = - 3 \frac{\dot a}{a}\left(\rho+\frac{p}{c^{2}}\right)</math>
:<math>\frac{\ddot a}{a} = - \frac{4\pi G}{3}\left(\rho + \frac{3p}{c^{2}}\right) + \frac{\Lambda c^{2}}{3}</math>
with <math>k</math>, the spatial curvature index, serving as a [[constant of integration]] for the first equation.
 
The first equation can be derived also from [[Thermodynamics of the universe|thermodynamical considerations]] and is equivalent to the [[first law of thermodynamics]], assuming the expansion of the universe is an [[adiabatic process]] (which is implicitly assumed in the derivation of the Friedmann–Lemaître–Robertson–Walker metric).
 
The second equation states that both the energy density and the pressure cause the expansion rate of the universe <math>{\dot a}</math> to decrease, i.e., both cause a deceleration in the expansion of the universe. This is a consequence of [[gravitation]], with pressure playing a similar role to that of energy (or mass) density, according to the principles of [[general relativity]]. The [[cosmological constant]], on the other hand, [[Dark energy|causes an acceleration in the expansion]] of the universe.
 
===Cosmological constant===
The [[cosmological constant]] term can be omitted if we make the following replacements
:<math>\rho \rightarrow \rho + \frac{\Lambda c^{2}}{8 \pi G}</math>
:<math>p \rightarrow p - \frac{\Lambda c^{4}}{8 \pi G}.</math>
 
Therefore the [[cosmological constant]] can be interpreted as arising from a form of energy which has negative pressure, equal in magnitude to its (positive) energy density:
:<math>p = - \rho c^2. \,</math>
Such form of energy—a generalization of the notion of a [[cosmological constant]]—is known as [[dark energy]].
 
In fact, in order to get a term which causes an acceleration of the universe expansion, it is enough to have a [[scalar field theory|scalar field]] which satisfies
:<math>p < - \frac {\rho c^2} {3}. \,</math>
Such a field is sometimes called [[Quintessence (physics)|quintessence]].
 
===Newtonian interpretation===
The Friedmann equations are equivalent to this pair of equations:
:<math> - a^3 {\dot \rho} = 3 a^2 {\dot a} \rho + \frac{3 a^2 p {\dot a}}{c^2} \,</math>
:<math>\frac{{\dot a}^2}{2} - \frac{G \frac{4 \pi a^3}{3} \rho}{a} = - \frac{k c^2}{2} \,.</math>
 
The first equation says that the decrease in the mass contained in a fixed cube (whose side is momentarily ''a'') is the amount which leaves through the sides due to the expansion of the universe plus the mass equivalent of the work done by pressure against the material being expelled. This is the conservation of mass-energy ([[first law of thermodynamics]]) contained within a part of the universe.
 
The second equation says that the kinetic energy (seen from the origin) of a particle of unit mass moving with the expansion plus its (negative) gravitational potential energy (relative to the mass contained in the sphere of matter closer to the origin) is equal to a constant related to the curvature of the universe. In other words, the energy (relative to the origin) of a co-moving particle in free-fall is conserved. General relativity merely adds a connection between the spatial curvature of the universe and the energy of such a particle: positive total energy implies negative curvature and negative total energy implies positive curvature.
 
The [[cosmological constant]] term is assumed to be treated as dark energy and thus merged into the density and pressure terms.
 
During the [[Planck epoch]], one cannot neglect [[quantum mechanics|quantum]] effects. So they may cause a deviation from the Friedmann equations.
 
== Name and history ==
 
The main results of the FLRW model were first derived by the Soviet mathematician [[Alexander Friedmann]] in 1922 and 1924. Although his work was published in the prestigious physics journal [[Zeitschrift für Physik]], it remained relatively unnoticed by his contemporaries. Friedmann was in direct communication with [[Albert Einstein]], who, on behalf of Zeitschrift für Physik, acted as the scientific referee of Friedmann's work. Eventually Einstein acknowledged the correctness of Friedmann's calculations, but failed to appreciate the physical significance of Friedmann's predictions.
 
Friedmann died in 1925. In 1927, [[Georges Lemaître]], a Belgian priest, astronomer and periodic professor of physics at the [[Catholic University of Leuven (1834–1968)|Catholic University of Leuven]], arrived independently at similar results as Friedmann and published them in Annals of the Scientific Society of Brussels. In the face of the observational evidence for the expansion of the universe obtained by [[Edwin Hubble]] in the late 1920s, Lemaître's results were noticed in particular by [[Arthur Eddington]], and in 1930–31 his paper was translated into English and published in the [[Monthly Notices of the Royal Astronomical Society]].
 
[[Howard P. Robertson]] from the US and [[Arthur Geoffrey Walker]] from the UK explored the problem further during the 1930s. In 1935 Robertson and Walker rigorously proved that the FLRW metric is the only one on a spacetime that is spatially homogeneous and isotropic (as noted above, this is a geometric result and is not tied specifically to the equations of general relativity, which were always assumed by Friedmann and Lemaître).
 
Because the dynamics of the FLRW model were derived by Friedmann and Lemaître, the latter two names are often omitted by scientists outside the US. Conversely, US physicists often refer to it as simply "Robertson–Walker". The full four-name title is the most democratic and it is frequently used.{{Citation needed|date=September 2011}} Often the "Robertson–Walker" ''metric'', so-called since they proved its generic properties, is distinguished from the dynamical "Friedmann-Lemaître" ''models'', specific solutions for ''a''(''t'') which assume that the only contributions to stress-energy are cold matter ("dust"), radiation, and a cosmological constant.
 
== Einstein's radius of the universe ==
 
'''Einstein's radius of the universe''' is the [[Radius of curvature (mathematics)|radius of curvature]] of space of [[Einstein's universe]], a long-abandoned [[Static spacetime|static]] model that was supposed to represent our universe in idealized form. Putting
:<math>\dot{a} = \ddot{a} = 0</math>
 
in the Friedmann equation, the radius of curvature of space of this universe (Einstein's radius) is{{Citation needed|date=June 2011}}
:<math>R_E=c/\sqrt {4\pi G\rho}</math>,
 
where <math>c</math> is the speed of light, <math>G</math> is the [[gravitational constant|Newtonian gravitational constant]], and <math>\rho</math> is the density of space of this universe. The numerical value of Einstein's radius is of the order of 10<sup>10</sup> [[light year]]s.

The Friedmann–Lemaître–Robertson–Walker (FLRW) metric is an exact solution of Einstein's field equations of general relativity; it describes a homogeneous, isotropic expanding or contracting universe that may be simply connected or multiply connected.[1][2][3] (If multiply connected, then each event in spacetime will be represented by more than one tuple of coordinates.) The general form of the metric follows from the geometric properties of homogeneity and isotropy; Einstein's field equations are only needed to derive the scale factor of the universe as a function of time. Depending on geographical or historical preferences, a subset of the four scientists — Alexander Friedmann, Georges Lemaître, Howard P. Robertson and Arthur Geoffrey Walker — may be named (e.g., Friedmann–Robertson–Walker (FRW) or Robertson–Walker (RW) or Friedmann–Lemaître (FL)). This model is sometimes called the Standard Model of modern cosmology.[4] It was developed independently by the named authors in the 1920s and 1930s.

General metric

The FLRW metric starts with the assumption of homogeneity and isotropy of space. It also assumes that the spatial component of the metric can be time-dependent. The generic metric which meets these conditions is

c2dτ2=c2dt2+a(t)2dΣ2

where Σ ranges over a 3-dimensional space of uniform curvature, that is, elliptical space, Euclidean space, or hyperbolic space. It is normally written as a function of three spatial coordinates, but there are several conventions for doing so, detailed below. dΣ does not depend on t — all of the time dependence is in the function a(t), known as the "scale factor".

Reduced-circumference polar coordinates

In reduced-circumference polar coordinates the spatial metric has the form

dΣ2=dr21kr2+r2dΩ2,where dΩ2=dθ2+sin2θdϕ2.

k is a constant representing the curvature of the space. There are two common unit conventions:

  • k may be taken to have units of length−2, in which case r has units of length and a(t) is unitless. k is then the Gaussian curvature of the space at the time when a(t) = 1. r is sometimes called the reduced circumference because it is equal to the measured circumference of a circle (at that value of r), centered at the origin, divided by 2Potter or Ceramic Artist Harry Rave from Cobden, spends time with hobbies for instance magic, property developers house in singapore singapore and fitness. Finds inspiration through travel and just spent 7 months at Keoladeo National Park. (like the r of Schwarzschild coordinates). Where appropriate, a(t) is often chosen to equal 1 in the present cosmological era, so that dΣ measures comoving distance.
  • Alternatively, k may be taken to belong to the set {−1,0,+1} (for negative, zero, and positive curvature respectively). Then r is unitless and a(t) has units of length. When k = ±1, a(t) is the radius of curvature of the space, and may also be written R(t).

A disadvantage of reduced circumference coordinates is that they cover only half of the 3-sphere in the case of positive curvature—circumferences beyond that point begin to decrease, leading to degeneracy. (This is not a problem if space is elliptical, i.e. a 3-sphere with opposite points identified.)

Hyperspherical coordinates

In hyperspherical or curvature-normalized coordinates the coordinate r is proportional to radial distance; this gives

dΣ2=dr2+Sk(r)2dΩ2

where dΩ is as before and

Sk(r)={k1sin(rk),k>0r,k=0|k|1sinh(r|k|),k<0.

As before, there are two common unit conventions:

  • k may be taken to have units of length−2, in which case r has units of length and a(t ) is unitless. k is then the Gaussian curvature of the space at the time when a(t ) = 1. Where appropriate, a(t ) is often chosen to equal 1 in the present cosmological era, so that dΣ measures comoving distance.
  • Alternatively, as before, k may be taken to belong to the set {−1,0,+1} (for negative, zero, and positive curvature respectively). Then r is unitless and a(t ) has units of length. When k = ±1, a(t ) is the radius of curvature of the space, and may also be written R(t ). Note that, when k = +1, r is essentially a third angle along with θ and φ. The letter χ may be used instead of r.

Though it is usually defined piecewise as above, S is an analytic function of both k and r. It can also be written as a power series

Sk(r)=n=0(1)nknr2n+1(2n+1)!=rkr36+k2r5120

or as

Sk(r)=rsinc(rk)

where sinc is the unnormalized sinc function and k is one of the imaginary, zero or real square roots of k. These definitions are valid for all k.

Cartesian coordinates

When k = 0 one may write simply

Einstein's field equations are not used in deriving the general form for the metric: it follows from the geometric properties of homogeneity and isotropy. However, determining the time evolution of a(t) does require Einstein's field equations together with a way of calculating the density, ρ(t), such as a cosmological equation of state.

This metric has an analytic solution to Einstein's field equations Gμν+Λgμν=8πGc4Tμν giving the Friedmann equations when the energy-momentum tensor is similarly assumed to be isotropic and homogeneous. The resulting equations are:[5]

(a˙a)2+kc2a2Λc23=8πG3ρ
2a¨a+(a˙a)2+kc2a2Λc2=8πGc2p.

These equations are the basis of the standard big bang cosmological model including the current ΛCDM model. Because the FLRW model assumes homogeneity, some popular accounts mistakenly assert that the big bang model cannot account for the observed lumpiness of the universe. In a strictly FLRW model, there are no clusters of galaxies, stars or people, since these are objects much denser than a typical part of the universe. Nonetheless, the FLRW model is used as a first approximation for the evolution of the real, lumpy universe because it is simple to calculate, and models which calculate the lumpiness in the universe are added onto the FLRW models as extensions. Most cosmologists agree that the observable universe is well approximated by an almost FLRW model, i.e., a model which follows the FLRW metric apart from primordial density fluctuations. Template:As of, the theoretical implications of the various extensions to the FLRW model appear to be well understood, and the goal is to make these consistent with observations from COBE and WMAP.

Interpretation

The pair of equations given above is equivalent to the following pair of equations

ρ˙=3a˙a(ρ+pc2)
a¨a=4πG3(ρ+3pc2)+Λc23

with k, the spatial curvature index, serving as a constant of integration for the first equation.

The first equation can be derived also from thermodynamical considerations and is equivalent to the first law of thermodynamics, assuming the expansion of the universe is an adiabatic process (which is implicitly assumed in the derivation of the Friedmann–Lemaître–Robertson–Walker metric).

The second equation states that both the energy density and the pressure cause the expansion rate of the universe a˙ to decrease, i.e., both cause a deceleration in the expansion of the universe. This is a consequence of gravitation, with pressure playing a similar role to that of energy (or mass) density, according to the principles of general relativity. The cosmological constant, on the other hand, causes an acceleration in the expansion of the universe.

Cosmological constant

The cosmological constant term can be omitted if we make the following replacements

ρρ+Λc28πG
ppΛc48πG.

Therefore the cosmological constant can be interpreted as arising from a form of energy which has negative pressure, equal in magnitude to its (positive) energy density:

p=ρc2.

Such form of energy—a generalization of the notion of a cosmological constant—is known as dark energy.

In fact, in order to get a term which causes an acceleration of the universe expansion, it is enough to have a scalar field which satisfies

p<ρc23.

Such a field is sometimes called quintessence.

Newtonian interpretation

The Friedmann equations are equivalent to this pair of equations:

a3ρ˙=3a2a˙ρ+3a2pa˙c2
a˙22G4πa33ρa=kc22.

The first equation says that the decrease in the mass contained in a fixed cube (whose side is momentarily a) is the amount which leaves through the sides due to the expansion of the universe plus the mass equivalent of the work done by pressure against the material being expelled. This is the conservation of mass-energy (first law of thermodynamics) contained within a part of the universe.

The second equation says that the kinetic energy (seen from the origin) of a particle of unit mass moving with the expansion plus its (negative) gravitational potential energy (relative to the mass contained in the sphere of matter closer to the origin) is equal to a constant related to the curvature of the universe. In other words, the energy (relative to the origin) of a co-moving particle in free-fall is conserved. General relativity merely adds a connection between the spatial curvature of the universe and the energy of such a particle: positive total energy implies negative curvature and negative total energy implies positive curvature.

The cosmological constant term is assumed to be treated as dark energy and thus merged into the density and pressure terms.

During the Planck epoch, one cannot neglect quantum effects. So they may cause a deviation from the Friedmann equations.

Name and history

The main results of the FLRW model were first derived by the Soviet mathematician Alexander Friedmann in 1922 and 1924. Although his work was published in the prestigious physics journal Zeitschrift für Physik, it remained relatively unnoticed by his contemporaries. Friedmann was in direct communication with Albert Einstein, who, on behalf of Zeitschrift für Physik, acted as the scientific referee of Friedmann's work. Eventually Einstein acknowledged the correctness of Friedmann's calculations, but failed to appreciate the physical significance of Friedmann's predictions.

Friedmann died in 1925. In 1927, Georges Lemaître, a Belgian priest, astronomer and periodic professor of physics at the Catholic University of Leuven, arrived independently at similar results as Friedmann and published them in Annals of the Scientific Society of Brussels. In the face of the observational evidence for the expansion of the universe obtained by Edwin Hubble in the late 1920s, Lemaître's results were noticed in particular by Arthur Eddington, and in 1930–31 his paper was translated into English and published in the Monthly Notices of the Royal Astronomical Society.

Howard P. Robertson from the US and Arthur Geoffrey Walker from the UK explored the problem further during the 1930s. In 1935 Robertson and Walker rigorously proved that the FLRW metric is the only one on a spacetime that is spatially homogeneous and isotropic (as noted above, this is a geometric result and is not tied specifically to the equations of general relativity, which were always assumed by Friedmann and Lemaître).

Because the dynamics of the FLRW model were derived by Friedmann and Lemaître, the latter two names are often omitted by scientists outside the US. Conversely, US physicists often refer to it as simply "Robertson–Walker". The full four-name title is the most democratic and it is frequently used.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park. Often the "Robertson–Walker" metric, so-called since they proved its generic properties, is distinguished from the dynamical "Friedmann-Lemaître" models, specific solutions for a(t) which assume that the only contributions to stress-energy are cold matter ("dust"), radiation, and a cosmological constant.

Einstein's radius of the universe

Einstein's radius of the universe is the radius of curvature of space of Einstein's universe, a long-abandoned static model that was supposed to represent our universe in idealized form. Putting

a˙=a¨=0

in the Friedmann equation, the radius of curvature of space of this universe (Einstein's radius) isPotter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

RE=c/4πGρ,

where c is the speed of light, G is the Newtonian gravitational constant, and ρ is the density of space of this universe. The numerical value of Einstein's radius is of the order of 1010 light years.

Evidence

By combining the observation data from some experiments such as WMAP and Planck with theoretical results of Ehlers–Geren–Sachs theorem and its generalization,[6] astrophysicists now agree that the universe is almost homogeneous and isotropic (when averaged over a very large scale) and thus nearly a FLRW spacetime.
