The equations of general relativity include a constant lambda in their solution. If lambda is non-zero and positive, this represents the phenomenon of cosmic repulsion. In this book Eddington discussed the implications of this repulsion for models of the universe.Contents: 1. The recession of the galaxies. 2. Spherical space. 3.

Bibcode: 1940Natur.145..549E Altcode: UNDOUBTEDLY, the mass of the radiation should be added to the mass of the stars and of the nebulous matter in computing the total mass of the universe. But the general belief is that its contribution is comparatively small-less than 1 per cent of the whole. This is not inconsistent with the figures cited by Admiral Beadnell. With radiation at the rate of 4 × 1028 tons per second, it would take 5 × 1018 seconds, or more than 1011 years, to accumulate to 1 per cent of the total mass 2 × 1049 tons. According to cosmological theory, the age of the stars can scarcely exceed 1010 years. Title: The correction of statistics for accidental error Authors: Eddington, A.

Bibcode: 1933Natur.132..639E Altcode: THE letter of Gamow and Landau1 suggests that an upper limit to the internal temperature of a star can be obtained by considering the disintegration of lithium. Investigations of this kind will probably be of great importance in the future development of astrophysics, but the actual proposal of Gamow and Landau rests on an assumption which is scarcely likely to be true. They postulate that any lithium found at the surface must have been carried there by diffusion from the central region, where it is presumed to have been created. Diffusion in a star is an exceedingly slow process, the time of relaxation being of the order 1013 years2. It would make small progress during the maximum age of the giant stars. But there is a process of mixing which is likely to operate much faster, namely, the circulating currents in meridian planes indirectly caused by the rotation of the star. The order of magnitude is indicated in an example treated by the writer in which the speed of the vertical current was found to be 60 metres a year3. The example was chosen with the view of giving an upper limit to the amount of this circulation ; but, allowing for slower currents in an average star, the lithium will be brought to the surface far more quickly in this way than by diffusion. Title: The Expanding Universe Authors: Eddington, A. S. Bibcode: 1933Natur.132..406E Altcode: I THINK everyone will agree with Miss Clark that if the distribution of nebular velocities is considered to be mainly a distance effect, it indicates an expanding system, whereas if it is mainly a time effect it indicates a system which is about to enter on a stage of contraction; and her letter is of service in pointing out the two alternatives. Adopting the hypothesis that it is a time effect, we see from her figures that 100 million years ago the spiral nebulæ (near and far) were moving away from our galaxy at 17,000 km. per sec, and that in the next 50 million years some kind of central attraction acting equally on near and distant nebulæ reduced the recession to 8,500 km. per sec. Formally there is nothing against this; but there is not much temptation to pursue the speculation unless some kind of cosmogonic explanation of the rather odd distribution of velocities and rather unusual law of attraction is offered. The most direct criticism is that the attractive force seems to be very much too large to be due to the ordinary gravitation of the system and has to be invented ad hoc.

Bibcode: 1930Natur.125..489E Altcode: I ASK your permission to reply to the arguments brought forward by Prof. Milne (NATURE, Mar. 22) against my treatment of the problem of stellar luminosity. The outcome of my investigation is a formula which predicts the luminosity of a star of given mass and radius (or mass and effective temperature). I have followed the common procedure of first employing special assumptions to make the mathematical answer definite, and then removing the assumptions by calculating the effect of the greatest admissible variation from the conditions adopted as standard-thus obtaining what is equivalent to a probable error of the prediction. The calculations of luminosity must, of course, be considered in conjunction with these estimates of probable error. I think that the discussion in ``Internal Constitution of the Stars'' of all known sources of uncertainty is exhaustive; and I conclude that the error is not so great as to impair the practical value of the formula. I have shown that differentially the result agrees excellently with observation, but absolutely it makes all the stars about ten times too bright. In view of this remaining discordance, I have been as eager as my critics in searching for possible loopholes or complications. If Milne's scrutiny brought to light any new possibility I should be grateful; but his criticism is not of this type. He claims that there is a fundamental inadequacy in my method, so that not even a rough value can be computed in this way.

S. Bibcode: 1928Natur.121..496E Altcode: THE problem of the general state of matter at high temperature is so fundamental in stellar physics that I venture to pursue the discussion with Dr. Jeans (NATURE, Feb. 25, p. 278). I would first thank him for his reply to my letter, which, though I differ from it on a number of points, deals fairly with the questions raised. I still believe I was not exaggerating in saying that Jeans's theory requires that the ions (in giant M stars) should be so large that they jam at densities that of air. Jeans wishes to amend this to 80 × air. But my figure represents the order of magnitude of the central density of Betelgeuse according to the usual gas model, and he has himself said that the star contracts as a gas until there are substantial deviations from the gas laws in the central regions. To form his liquid core of higher density it would seem that Betelgeuse must have contracted as a gas to its present radius, and then for unexplained reasons thrown out a gaseous envelope filling the present volume. Or starting from his liquid core of density 80 × air, we have to face the problem of balancing on this a gaseous atmosphere containing much less mass and subject initially to 8000 times the gravitation of the ordinary model. I think that to achieve this Dr. Jeans will have to depart much more widely from current theory than he intended. Title: The deviation of stellar material from a perfect gas Authors: Eddington, A. S.

Bibcode: 1928Natur.121..278E Altcode: IN NATURE of Feb. 4 (p. 173), Dr. Jeans has given an attractive exposition of his new theory of stellar evolution involving `liquid' stars. With all goodwill towards innovations which might help to remove present difficulties of the evolutionary theory, I cannot follow Dr. Jeans's lead because I find myself in disagreement with him on two preliminary and essential points. These points, discussed separately below, have already been the subject of careful investigation, and even in Dr. Jeans's fuller papers on his theory I find no new considerations which would modify the conclusions formed.

Bibcode: 1925MNRAS..86....2E Altcode: No abstract at ADS Title: Ether-drift and the Relativity Theory Authors: Eddington, A. S. Bibcode: 1925Natur.115..870E Altcode: THE brief messages in the daily press with regard to Prof. D. C. Miller's experiment have aroused much interest and bewilderment; it is therefore of great value to have Dr. Silberstein's authoritative account in NATURE for May 23. Comment on the experiments themselves would be out of place until the details are published; but it may not be premature to point out that the surprising hypothesis of ether-drift, by which it is proposed to account for the results, is disproved in advance by the daily measurements at astronomical observatories. These measurements constitute a test for differential ether-drift much more delicate than the Michelson-Morley experiment. Title: The Source of Stellar Energy Authors: Eddington, A. S. Bibcode: 1925Natur.115..419E Altcode: THE source of a star's energy is debated in recent letters by Prof. Lindemann and Dr. Jeans (NATURE, Feb. 14 and 28). Dr. Jeans's conclusion is that the liberation of energy from the sub-atomic store occurs at a rate independent of temperature and density; and if one star liberates energy more slowly than another, it is solely because the former has exhausted the more prolific material. I think that there are grave astronomical objections to this view. Title: Circulating currents in rotating stars Authors: Eddington, A. S.

Bibcode: 1924Natur.113..746E Altcode: IN a letter to NATURE of April 26, Dr. Silberstein makes a proposal for determining the distance of a remote star by observing the displacement of the spectral lines at six months interval; he claims that this method will separate the ordinary Doppler effect of the unknown motion of the star from the distance-effect predicted by de Sitter. It seems to me clear that this proposal contains a fallacy. The material to be experimented on is a certain regular train of light-waves proceeding through the small region round the sun accessible to us; the star itself is inaccessible. The frequency of these waves is to be measured by two observers-for example, a January observer and a July observer. These observers differ only in their velocities V1 and V2 relative to the frame of reference; Dr. Silberstein neglects any effects of the short interval of time and of space between the two observations and of the distortion of the waves by the local gravitational field.

Bibcode: 1924Natur.113..192E Altcode: IN Whitehead's theory of gravitation, as in Einstein's, the tracks of particles in a gravitational field are determined by the condition that a certain integral taken along the track is stationary. The integrand is denoted by dJ in Whitehead's theory and ds in Einstein's. Light-tracks are further conditioned by dJ or ds, respectively, being zero. Since both theories are known to give the observed results for the perihelion of Mercury and the deflexion of light, dJ cannot be widely different from ds in the field of a single particle (the sun); but I do not think it has hitherto been noticed that dJ is exactly equal to ds.

Bibcode: 1922Natur.110..697E Altcode: I CANNOT resist Mr. Cunningham's invitation in his review of my Romanes Lecture (NATURE, Oct. 28, p. 568) to justify more precisely the transition from the picture of world-history as a tangle of world-lines to the scheme of intervals filling a continuum of space-time and demanding non-Euclidean geometry. `` Prof. Eddington seems to contemplate as `measurable' the intervals between pairs of points in this continuum which do not correspond to events in the history of any particle or electron in the material universe. But we wish to ask him how these intervals are in practice to be measured.'' Mr. Cunningham's point is that the picture which we have to dissect is the actual history of the world, and we are not allowed to alter it-to introduce measurements which never were made, or to introduce physically recognisable events at points where nothing actually happened. I accept this limitation. He admits, however, that all measurements that have ever been made are contained in the picture, and, I might add, all measurements that ever will be made. Thus we have a large number of measured intervals available for discussion; and I think that Mr. Cunningham, like myself, is convinced that the geometry which these measured intervals obey is not exactly Euclidean but is given correctly by Einstein. When once this geometry is determined we proceed to fill all space-time with calculated points and intervals ; just as we ordinarily fill all space with calculated points and distances after first determining the geometry by means of a few distances actually measured and a few points actually perceptible. Only a small number of the calculated points and intervals correspond to events and measurements in the historical picture; but whenever there is a measured value it will agree with the calculated value.

Bibcode: 1921Natur.107..170E Altcode: I AM indebted to the Editor's courtesy for the opportunity to comment on the foregoing letter. In deciding whether an approximation is allowable, regard must be had to the problem to which it is to be applied. It is true that equation (3) neglects a term of importance in the motion of the apse, and is therefore not valid for the problem of the perihelion of Mercury; but there may be other problems for which the approximation can be justified. One of these is the calculation of the Gμν for continuous matter on p. 59 of my ``Report''. My proof starts with the approximate calculation of the line-element in a sphere which is ultimately made infinitely small; I think that the justification of the neglect of m21 given in § 36 is correct, though the argument is intricate, and I would welcome detailed criticism. But, for example, my formulæ are not sufficiently accurate to give the rotation of the apse-line of a particle moving freely through a diffuse spherical nebula.

ANDERSON suggested in NATURE of December 4 (p. 354) a possible source of systematic error in the determination of the deflection of light at an eclipse, owing to lateral refraction caused by a temperature-gradient in the shadow-cone in our atmosphere. Having carefully considered this suggestion, I feel convinced that the effects of any possible temperature-gradient would be small. Title: The sources of stellar energy Authors: Eddington, A. S.

Bibcode: 1917Natur..99..445E Altcode: I AM in general agreement with Mr. Jeans's remarks on the difficulty of obtaining a source of stellar energy more powerful than the Helmholtz contraction. It may be added that there is a conceivable source, which was, I believe, once suggested by Mr. Jeans himself, viz. a gradual annihilation of matter by positive and negative electrons occasionally neutralising one another. This would provide an almost inexhaustible store of energy, but there is the grave objection that it affords no reason why the, dense dwarf stars should liberate so much less energy than rarefied stars of the same mass. One would have expected compression to be favourable to the process of cancelling of electrons. The search for an additional store of energy is not at all encouraging; but, on the other hand, there are important arguments against the short time-scale-notably Prof. Strutt's evidence of the age of terrestrial rocks, and the time needed for the tidal evolution of the earth-moon system. I have not felt myself able to combat the arguments on one side any more than on the other; accordingly, in the paper criticised by Mr. Jeans, the question was left entirely open. In the one place where it was necessary to consider the source of stellar energy, I attempted to show that my formula fairly represented both the radio-activity and the contraction hypotheses-having regard to the necessarily approximate character of the investigation. Title: The Radiation of the Stars Authors: Eddington, A. S. Bibcode: 1917Natur..99..365E Altcode: MR. JEANS'S criticism of the dimensions of my equation, ``radiation-pressure=gravity,'' is clearly only a verbal matter. It may be preferable to expand the sentence so as to read, ``force on material due to radiation-pressure=force on material due to gravity.'' But statements that radiation-pressure is x times gravity have been commonly made in connection with the theory of the repulsion of comets' tails, and I thought the reader would have no difficulty in inter- preting my statement in the same sense.
