According to FLRW model, Big Bang is taking place right now, everywhere

According to ‘FLRW metric’ expansion of space is taking place all the time everywhere. If 1 mm distance is becoming 2 mm in 1 billion years then 2 mm is becoming 4 mm in same 1 billion year and so on. Every length of space has to become double in same 1 billion years.

So it is like Big Bang of creation of empty space taking place right now – everywhere. Nothing solid is being created by this everyday-everywhere happening Big Bang. However solid things are getting distant apart due to this all the time everywhere happening Big Bang.

And we are told that this is science. Failure to rightly explain cosmological redshifts has resulted in this non-sense Physics. This is really possible only in balloon surface like expansion where every point of surface keeps on expanding. But balloon is expanded due to continuous application of pumping action or force whereas in Big Bang Model, it is said that only the original one time pumping action is still doing its work. It cannot be argued that current expansion is the inertial motion generated by original one time Big Bang because it is not one time thing. This ‘Big Bang’ is taking place all the time – even now.

This type of Big Bang is all the time creating only ‘new empty space’. We should conclude that matter was never created by Big Bang. Matter existed already. Big Bang could only create ‘space’ and even now doing only the same. Given that Universe existed prior to Big Bang, the Big Bang only started ‘expansion’. Before start of Big Bang, it was a static universe. After stoppage of ongoing Big Bang, universe shall be again static.

Edwin Hubble did not say in 1929 that ‘Universe is Expanding’. Here is the original 1929 paper:

Edwin Hubble DID NOT say that Universe is expanding.

Let us see what he actually said in year 1929. Following is link to his original 1929 paper:

A relation between distance and radial velocity among extra-galactic nebulae

Title of the paper is: “A relation between distance and radial velocity among extra-galactic nebulae.”

Here “radial velocity” means “redshift”.

From 1912 onwards, scientists had been noticing redshifts in far off galaxies (then thought of spiral nebulae). Naturally by that time those redshifts were interpreted in terms of Doppler’s Effect. Due to Doppler’s interpretation, those redshifts were also called “radial velocities”.

Here in the title of his paper, Hubble has used common term “radial velocity” for “redshift”.

But to determine what he actually wants to say, we must very carefully study the first paragraph of 1929 paper. Following is the first paragraph:

“Determinations of the motion of the sun with respect to the extra-galactic nebulae have involved a K term of several hundred kilometers which appears to be variable. Explanations of this paradox have been sought in a correlation between apparent radial velocities and distances, but so far the results have not been convincing. The present paper is a re-examination of the question, based on only those nebular distances which are believed to be fairly reliable.”

Here it is also true that he starts his paper with sentence “Determinations of the motion of the sun with respect to the extra-galactic nebulae”.

But … in the very first paragraph … he is pointing something perplexing for which he is using word ‘paradox’ and after pointing out this ‘paradox’, now he is using term apparent velocities instead of velocities.

Following is relevant sentence in the first paragraph:

“Explanations of this paradox have been sought in a correlation between apparent radial velocities and distances, but so far the results have not been convincing.”

Here is the point. In Doppler’s Shift, there is no redshift-distance relationship but what Hubble was observing was a redshift-distance relationship. Therefore with this paper, he was seeking explanations for this ‘paradox’.

From whom he was seeking explanation?

He wrote this question in a public paper so he asked it from wise community. But he asked for this explanation from particular people of his choice also. Furthermore, he has skeptically concluded this paper with following words:

“In the de Sitter cosmology, displacements of the spectra arise from two sources, an apparent slowing down of atomic vibrations and a general tendency of material particles to scatter. The latter involves an acceleration and hence introduces the element of time. The relative importance of these two effects should determine the form of the relation between distances and observed velocities; and in this connection it may be emphasized that the linear relation found in the present discussion is a first approximation representing a restricted range in distance.”

 In the letter to de-Sitter, he writes:

“Mr. Humason and I are both deeply sensible of your gracious appreciation of the papers on velocities and distances of nebulae. We use the term ‘apparent’ velocities to emphasize the empirical features of the correlation. The interpretation, we feel, should be left to you and the very few others who are competent to discuss the matter with authority.[i]”

 Thus ‘apparently’ redshifts seemed like velocities but for Hubble, the actual interpretation of redshifts was unresolved question. With this, he actually rightly recognized the fact that redshift involved in extra galactic nebulae was of a different kind than to the usual Doppler’s Shift.

With his 1929 paper, Hubble not only did not suggest ‘expansion of universe’, he also almost denied that meaning of ‘redshifts’ was ‘velocities’. He used term ‘apparent velocities’ and he even looked for such reasons of redshift as apparent slowing down of atomic vibrations and a general tendency of material particles to scatter.

The usage of term ‘apparent’ for velocities and then looking for explanation of redshifts in such reasons as apparent slowing down of atomic vibrations and a general tendency of material particles to scatter indicates that for Edwin Hubble, ‘velocities’ was not the final meaning for redshifts. The term ‘apparent’ points to the determination of meaning of redshifts as indeterminate.

But soon Robertson and Walker were going to give him an undue gift of literal meaning of ‘apparent velocities’. FLRW metric (Friedmann-Lemaître-Robertson-Walker) was declared to be the only possible interpretation of cosmological redshifts. In this so-called metric, ‘apparent velocities’ of galaxies literally became ‘apparent velocities’ such that there was no actual velocity but ‘space’ was expanding thus galaxies were ‘apparently’ receding away from our solar system.

Whatever FLRW metric says but point of this blog post is only to show that Edwin Hubble himself did not suggest expansion of universe and neither did he took redshifts of galaxies as actual receding velocities of those galaxies.

After having seen what Hubble exactly told us in year 1929, now we should guess the level of misinformation in general public about Hubble’s finding when NASA itself is also gravely misinformed. Following is a quote from NASA website:

https://map.gsfc.nasa.gov/universe/bb_tests_exp.html

“The Big Bang model was a natural outcome of Einstein’s General Relativity as applied to a homogeneous universe. However, in 1917, the idea that the universe was expanding was thought to be absurd. So Einstein invented the cosmological constant as a term in his General Relativity theory that allowed for a static universe. In 1929, Edwin Hubble announced that his observations of galaxies outside our own Milky Way showed that they were systematically moving away from us with a speed that was proportional to their distance from us. The more distant the galaxy, the faster it was receding from us. The universe was expanding after all, just as General Relativity originally predicted! Hubble observed that the light from a given galaxy was shifted further toward the red end of the light spectrum the further that galaxy was from our galaxy.”

For heaven’s sake NASA – Hubble DID NOT say that galaxies are ‘moving away’. At the most he said that galaxies are APPARENTLY moving away.

Preface

The analysis in this book is started with the confirmed fact that Alexander Friedmann’s 1922 work had no relation with Hubble’s Law that was yet to be found by Edwin Hubble in 1929. Official sources repeatedly tell us that Georges Lemaître had found similar to Friedmann’s solution in year 1927 so I thought that Lemaître’s work also should have no actual relation with Hubble’s Law. My analysis kept going with this assumption till section I.III where I realized that if unlike Friedmann, Lemaître had the data of Doppler’s Redshifts of various galaxies, then he also could have means to find the distance of those galaxies. Admittedly, this book up to section I.III is an analysis based on an incorrect assumption that by 1927, Lemaître should be unaware of Hubble Type redshift-distance relationship in light coming from far off galaxies. But that analysis forced me to download 1927 paper of Lemaître. Initially I found English Translation (1931) by the title: “A Homogeneous Universe of Constant Mass and Increasing Radius accounting for the Radial Velocity of Extra-galactic Nebulæ”. I was shocked to see that my analysis was wrong up to section I.III because apparently Lemaître had already derived Hubble type redshift-distance relationship solely from General Relativity (GR) Equations. But I was not wrong. This was a manipulated translation; he had not derived that relationship from GR equations rather had derived from a method which he took directly from Hubble himself, detail thereof I have explained in this book. Here in this book, original papers of Friedmann (1922), Lemaître (1927), Edwin Hubble (1929), Albert Einstein (1917) along with other important relevant papers have been analyzed and only the most fundamental aspects like expansion and CMBR of Big Bang Cosmology are covered. If these two aspects of Big Bang Cosmology are precisely refuted then there is nothing crucial left with the standard model.

Philosophy is not concerned with providing definite solutions to the problems. Therefore, alternatives suggested in this book should not literally be taken as definite alternatives. They however represent philosophically solid and justified positions and it is up to readers who should conclude the matter by applying their own critical judgment. This book will however expose the undue authoritative nature of FLRW metric and with this book, Big Bang Theory is set to become a story of past.
