They can claim whatever they want about the big bang...the simple fact of the matter is that it is postulated from observances that we make AFTERWARDS...we have no way of knowing that what we THINK caused what we observe is really what happened....so technically, it can't be replicated or validated scientifically...it's just a well-thought out guess....unlike other theories...that can be validated scientifically....
The point is...the theory of relativity...observed...through our observations it's deemed "correct"....atomic theory...observed...through our observations it's deemed "correct"....etc etc
big bang theory....not observed...cannot be deemed "correct" through our observations...because our observations aren't relevant to the timeframe....the big bang happened in an instant...relativity...atomic theory...they persist...there's no 'one' point in "time" when they happened......
Gravity...is OBSERVED...WE SEE IT WORKING EVERY DAY...WE CAN TEST IT...

Or you can just say the Big Bang is an atheistic word for GOD.

big bang theory....not observed...
The existence of the CMB radiation was first predicted by Ralph Alpher, Robert Herman, and George Gamow in 1948, as part of their work on Big Bang Nucleosynthesis. It was first observed inadvertently in 1965 by Arno Penzias and Robert Wilson at the Bell Telephone Laboratories in Murray Hill, New Jersey.
This figure shows the prediction of the Big Bang theory for the energy spectrum of the cosmic microwave background radiation compared to the observed energy spectrum. The FIRAS experiment measured the spectrum at 34 equally spaced points along the blackbody curve. The error bars on the data points are so small that they can not be seen under the predicted curve in the figure! There is no alternative theory yet proposed that predicts this energy spectrum. The accurate measurement of its shape was another important test of the Big Bang theory.
(The Big Bang) cannot be deemed "correct" through our observations...
The concept of the Big Bang was not immediately obvious to astrophysicists, but rather grew out of a steady accumulation of evidence gathered from both theoretical and observational research throughout the course of the 20th century. A wide range of theories attempting to explain the origin of the Universe were eventually discredited and superseded by the Big Bang hypothesis based upon the following critical considerations:
- the current expansion, or Hubble flow, of the Universe
- the observed helium and deuterium abundances
- the cosmic background radiation
- the cosmological solutions of Einstein's equations
- agreement between various independent estimates of the age of the Universe
What is the evidence against the Big Bang?
Light Element Abundances predict contradictory densities
Large-scale Voids are too old
Surface brightness is constant
Too many Hypothetical Entities--Dark Matter and Energy, Inflation
No room for dark matter
No Conservation of Energy
Alignment of CBR with the Local Supercluster
The ambition to find the ultimate reason for the existence of everything may be acceptable as a (pseudo-) religious quest but hardly as an objective and rational scientific endeavour. It is obvious that the assumption of a 'creation' is logically inconsistent with the scientific principle of cause and effect. Any valid scientific approach is therefore necessarily tied to the infinite dimensions of space and time as the forms of existence (the argument of cosmologists that time and space came only into existence at the 'time' of the big bang is a logical contradiction in itself and therefore scientifically nonsense).
The microwave “background” makes more sense as the limiting temperature of space heated by starlight than as the remnant of a fireball.
The expression “the temperature of space” is the title of chapter 13 of Sir Arthur Eddington’s famous 1926 work, [] Eddington calculated the minimum temperature any body in space would cool to, given that it is immersed in the radiation of distant starlight. With no adjustable parameters, he obtained 3°K (later refined to 2.8°K []), essentially the same as the observed, so-called “background”, temperature. A similar calculation, although with less certain accuracy, applies to the limiting temperature of intergalactic space because of the radiation of galaxy light. [] So the intergalactic matter is like a “fog”, and would therefore provide a simpler explanation for the microwave radiation, including its blackbody-shaped spectrum.
Such a fog also explains the otherwise troublesome ratio of infrared to radio intensities of radio galaxies. [] The amount of radiation emitted by distant galaxies falls with increasing wavelengths, as expected if the longer wavelengths are scattered by the intergalactic medium. For example, the brightness ratio of radio galaxies at infrared and radio wavelengths changes with distance in a way which implies absorption. Basically, this means that the longer wavelengths are more easily absorbed by material between the galaxies. But then the microwave radiation (between the two wavelengths) should be absorbed by that medium too, and has no chance to reach us from such great distances, or to remain perfectly uniform while doing so. It must instead result from the radiation of microwaves from the intergalactic medium. This argument alone implies that the microwaves could not be coming directly to us from a distance beyond all the galaxies, and therefore that the Big Bang theory cannot be correct.
None of the predictions of the background temperature based on the Big Bang were close enough to qualify as successes, the worst being Gamow’s upward-revised estimate of 50°K made in 1961, just two years before the actual discovery. Clearly, without a realistic quantitative prediction, the Big Bang’s hypothetical “fireball” becomes indistinguishable from the natural minimum temperature of all cold matter in space. But none of the predictions, which ranged between 5°K and 50°K, matched observations. [] And the Big Bang offers no explanation for the kind of intensity variations with wavelength seen in radio galaxies.
The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.
According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know.
