has detailed prominent inconsistencies with the said model. The redshift controversy pointed out by several cosmologists from time to time, presence of full-bloomed galaxies with higher metallicity in the very early epoch of the universe, as also the presence of superclusters of galaxies and supervoids in the cosmos are some of the unsolved mysteries that remain inexplicable by the Big Bang model. It is ironic that the mainstream cosmologists have remained indifferent to admit the cosmological realities despite the loopholes with the said model repeatedly being pointed out from time to time. Ironically, Hawking’s immense popularity as a popular science writer hinges upon success of his widely popular book, ‘A Brief History of Time’ that is all about the origin of the universe. Authencity of the information contained in these books depends on the validity of the ‘Big Bang Model’.When the said model itself in mired in deep controversy, what Hawking has been preaching to the world is mere a gossip without any iota of truth.

The Redshift Controversy:
As per Hubble’s law, galaxies in the cosmos are observed to recede on account of expansion of universe. However, there remains nagging uncertainty whether the redshift calculated on the basis of Hubble’s law gives true value of the receding galaxies. Some astronomers (Narlikar 1989; Parker 1993; Harrison 1993; Longair 1995) have serious reservations about the authenticity of the galactic velocities catalogued by astronomers using the Hubble’s velocity- distance law, v = Hd. Expansion redshift does not arise from the Doppler effect, nor is the redshift related to velocity by the special relativistic relation, 1+z =[(1+v/c)/(1-v/c)]1/2 (Narlikar 1993). Einstein’s relativistic Doppler formula merely applies to the motion of galaxies through space, it does not apply to the recession of galaxies (Seeds 2007). Moreover, Doppler redshift is bound by the laws of Einstein’s special relativity, which dictates that an object cannot travel faster than the speed of light whereas in the case of cosmological redshift, v > c is possible since the space which separates the objects (e.g. a quasar from the Earth) through a vacuum can expand faster than the speed of light.
Under the cosmological redshift interpretation, galaxies are not receding simply by a physical velocity in the direction away from the observer; instead, the intervening space is expanding, which accounts for large-scale isotropy of the effect demanded by the cosmological principle (Harrison 1981). In the current cosmological model (Gray and Davies 2008), cosmological redshift z(cos) is described as the observable time-dependent cosmic scale factor (a), governed by the expression,
1+z(cos)= a(now)/a(then). Bondi (1947) defined cosmological redshift as the summation of the Doppler shift due to an object’s motion through space, and the global gravitational shift (Einstein effect) due to the difference between the potential energy per unit mass at the source and the observer. Mathematically, cosmological redshift is expressed as z(cos) = z(dop)+ z(grav), where 1+ z(cos) =[(1+v/c)/(1-v/c)]1/2 (1+∆Ф/c2), and ∆Ф is the difference in gravitational potential between the points of emission and reception of a photon, which hints at the Doppler shift not being the correct measure of distance between the source and the observer.
The inflationary concept (in the Inflationary Big Bang Model), supporting a vacuum-dominated universe (arising out of quantum fluctuations) during phase transition in the early history of the universe was evolved by some cosmologists (Guth 1981; Linde 1982) to circumvent problems of ‘flatness’, ‘horizon’ and the ‘primordial magnetic monopole’ associated with the Big Bang model. The hypothetical inflation field giving rise to inflation, however, is very speculative lacking sound scientific explanation.There is no general consensus among cosmologists regarding the timing of the beginning and end of the inflationary epoch. In Linde’s ‘chaotic inflation’, inflation starts at the Planck time, 10 -43 sec when the temperature was 10 32 K, whereas in other models, inflation starts when the temperature falls to the point
(10 -35 sec after Big Bang when the temperature was ~10 28 K) at which the symmetry of the Grand Unified Theory (GUT) is spontaneously broken.
Element of arbitrariness is also quite prominent in regard to interpretation of the cosmological costant in Einstein’s equations of general relativity. Some cosmologists have related the cosmological cosnstant to the dark energy following observations in 1998 of very distant galaxies that were suggestive of accelerating expannsion of the universe. Ironically, the true nature of the 73% dark energy and 23% dark matter ( as per the latest WMAP intertretations) pervading the universe hitherto remains elusive.
"Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist."
- Stephen Hawking in “The Grand Design”
“As recent advances in cosmology suggest, the laws of gravity and quantum theory allow universes to appear spontaneously from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.”
- Stephen Hawking, Ibid
Here three questions can be asked:
1) Which one came first, universe, or laws of gravity and quantum theory?
2) If the universe came first, then how was there spontaneous creation without the laws of gravity and quantum theory?
3) If the laws of gravity and quantum theory came first, then Hawking has merely substituted God with quantum theory and laws of gravity. These two together can be called Hawking's "Unconscious God". Therefore we can legitimately ask the question: Who, or what, created Hawking's unconscious God?
Not only this, but there are other problems also. If the laws of gravity and quantum theory allow universes spontaneously appearing from nothing, then initially there was nothing. Then wherefrom appear those laws of gravity and quantum theory to allow universes appearing spontaneously from nothing? In which container were those two laws of nature?
Now regarding the M-theory: I have already written something on multiverse theory (not yet published anywhere). There I have come to the conclusion that if there are an infinite number of universes, then only within that infinite number of universes there will certainly be at least one universe in which life will emerge. If the number of universes is only 10 to the power 500, then it is very much unlikely that any one of them will support life, because no universe will know which set of values the other universes have already taken, and if everything is left on chance, then there is every probability that all the universes will take only those set of values that will not support life. There will be no mechanism that will prevent any universe from taking the same set of values that have already been taken by other universes. There will be no mechanism that will take an overview of all the universes already generated, and seeing that in none of them life has actually emerged will move the things in such a way that at least one universe going to be generated afterwards will definitely get the value of the parameters just right for the emergence of life. Only in case of an infinite number of universes this problem will not be there. This is because if we subtract 10 to the power 500 from infinity, then also we will get infinity. If we subtract infinity from infinity, still then we will be left with infinity. So we are always left with an infinite number of universes out of which in at least one universe life will definitely emerge. Therefore if M-theory shows that it can possibly have 10 to the power 500 number of solutions, and that thus there might be 10 to the power 500 number of universes in each of which physical laws would be different, then it is really a poor theory, because it cannot give us any assurance that life will certainly emerge in at least one universe. So instead of M-theory we need another theory that will actually have an infinite number of solutions.
Now the next question to be pondered is this: How did the scientists come to know that an entire universe could come out of nothing? Or, how did they come to know that anything at all could come out of nothing? Were they present at that moment when the universe was being born? As that was not the case at all, therefore they did not get that idea being present at the creation event. Rather they got this idea being present here on this very earth. They have created a vacuum artificially, and then they have observed that virtual particles (electron-positron pairs) are still appearing spontaneously out of that vacuum and then disappearing again. From that observation they have first speculated, and then ultimately theorized, that an entire universe could also come out of nothing. But here their entire logic is flawed. These scientists are all born and brought up within the Christian tradition. Maybe they have downright rejected the Christian world-view, but they cannot say that they are all ignorant of that world-view. According to that world-view God is omnipotent, omniscient and omnipresent. So as per Christian belief-system, and not only as per Christian belief-system, but as per other belief-systems also, God is everywhere. So when these scientists are saying that the void is a real void, God is already dead and non-existent for them. But these scientists know very well that non-existence of God will not be finally established until and unless it is shown that the origin of the universe can also be explained without invoking God. Creation event is the ultimate event where God will have to be made redundant, and if that can be done successfully then that will prove beyond any reasonable doubt that God does not exist. So how have they accomplished that job, the job of making God redundant in case of creation event? These were the steps:
1) God is non-existent, and so, the void is a real void. Without the pre-supposition that God does not exist, it cannot be concluded that the void is a real void.
2) As virtual particles can come out of the void, so also the entire universe. Our universe has actually originated from the void due to a quantum fluctuation in it.
3) This shows that God was not necessary to light the blue touch paper and set the universe going, as because there was no creation event.
4) This further shows that God does not exist.
So here what is to be proved has been proved based on the assumption that it has already been proved. Philosophy is already dead for these scientists. Is it that logic is also dead for them?
