Mainstream physics and cosmology defend the Big Bang theory as if it was sacred. But the process of scientific progress is not being made at the basis of ignoring any other viable explenation of the cosmos.
The Big Bang theory has a number of problems. One of them is that we need to assume that almost 95% of the contents of the universe is made of some unknown stuff (dark matter/energy) for which there is no observational evidence. The Big Bang theory is patched any time observational evidence shows that the predictions of the theory don't hold.
The more philosophical typed problems of the BB Theory is that in some way the theory urges us to assume that the universe must have had some cause.
An alternative physics theory, I recently came accross, makes different approaches on many terrains, and comes up with a consistent theory of physics.
In last instance this theory just makes only one assumption, namely that space itself is an eternal and infinite substance in eternal motion, and causes all the known phenemona of the universe in the form of wave interactions.
In this physics theory, there aren't any particles, but the phenomena which we call or see as particles are just the consequences of standing waves in the space medium.
The theory is known as Wave Structure of Matter.
Apart from a total new and different physics theory, it also is an alternative to the Big Bang, as it has a different explenation for both red shift and cosmic background radiation.
In WSM theory (Wave Structure if Matter) the universe is a finite part of infinite and eternal space. The size of the universe is just determined by the maximum distance waves can interact. Every point in space has a spherical shell around it, it is the center of it's own universe.
And because of that maximum distance, the universe shells of two distant points have less common 'universe', and that is what we see as redshift. It explains why there is a redshift - distance relationship.
Apart from other mechanisms that can cause redshift.
This is a very simple and brief explenation, and shows that the pilars of the Big Bang theory might fall.
Since the theory is rather new (although not that new, some principles have been put forward several hundred years ago), from what I know about it, this theory is in accordance with known physical observations.
General Theory of Relativity, Quantum Mechanics, etc. don't go directly out of the window, as these ideas are basically right, and can be incorporated into WSM theory.
I just present it here, for people to get in touch with it and hopefully discuss it on here, as als a viable alternative for the BB theory.
According to WSM theory, there was no Big Bang, since there is no expansion of the universe, and space itself as the primal substance is both eternal and infinite and in motion.
The principles of WSM theory are very simple, but the impact is great.
