Eric Lerner. Professional work[edit] Lerner received a BA in physics from Columbia University[4] and started as a graduate student in physics at the University of Maryland, but left after a year due to his dissatisfaction with the mathematical rather than experimental approach there.[5][6] He then pursued a career in popular science writing.
Lerner is also an active general science writer, estimating that he has had about 600 articles published.[3] He has received journalism awards between 1984 and 1993 from the Aviation Space Writers Association.

Errors in the "The Big Bang Never Happened" Top | Criticism | Alternative | Miscellaneous | Bottom Eric Lerner starts his book "The Big Bang Never Happened" (hereafter BBNH) with the "errors" that he thinks invalidate the Big Bang.
These are Are these criticisms correct? No, and they were known to be incorrect in 1991 when Lerner wrote his book. Let us look at the superclusters first. Lerner gives the example of filaments or sheets 150 million light years apart in Figure 1.1, and then asserts that material would have to travel 270 million light years to make the structure.

Olbers' Paradox - by Eduardo Manuel Alvarez: Back to Cosmology Introduction Olbers' ParadoxAnalysis of Proposed SolutionsFinal Explanation ConclusionReferences Introduction During a warm summer night last January, two couples of friends, my wife and I were having a great time while dining out in the open at the pavement of an enjoyable little downtown restaurant.
Suddenly, at the final coffees, all lights were off. Having realized that the best thing to do was just waiting for the lights to come back (instead of “rapidly disappearing”, like someone actually suggested) the amicable chat resumed under a complete darkness. Knowing my great fondness for astronomy, all kind of questions were immediately shot over me, mostly the usual trivial ones. Apparently simple and naive, my friends had posed a very hard question.

Can anything 'real' be infinite? Can anything 'real' be infinite?
We often here the terms 'infinite' and 'infinity', sometimes used in connection with the size of the universe, such as an infinite universe for example. The terms more properly belong in the world of mathematics, where for example we may have an infinitely long string of numbers as the result of a calculation, such as pi. The terms are very real to mathematics, but can anything real, not theoretical, be infinite? An infinite Universe? Coma galaxy cluster Naturally in mathematics we can have infinity, numbers go on for ever, but numbers are not real, they are abstract. The concept of infinity is a puzzling one.

Cosmology Olbers' Paradox I am indebted to Professor Peter Saulson for the artistic comparisons I use below.
While "his" paradox had been considered by other astronomers all the way back to Kepler, Heinrich Olbers (1926) gave the question its final shape: Why is the night sky black? If we assume that the universe is infinite and stars are evenly distributed throughout the universe we ought to see a star in any direction we look. We can safely assume that all stars have the same surface brightness on the average as the Sun; it is simply that they are so far away that they appear very small. Consider a 100-watt light bulb, on the table next to you. Now consider this: the light from an individual star falls off as the square of its distance r. Www.ronaldkoster.net//olber.pdf.

Inferences from the dark sky: Olbers' paradox The classical formulation of "Olbers' Paradox" consists in looking for an explanation of the fact that the sky at night is dark. We use the experimental datum of the nocturnal darkness in order to put constraints on a Newtonian cosmological model. We infer then that the Universe, in such a model, should have had an origin at a finite time in the past. John Baes gives a brief, but, illuminating discussion See The most important point, IMO, if infinitely old and populated, the universe should be in thermal equilibrium.
