Yes, there is sufficient evidence of a big bang event and a high density early environment dated about 13.8 billion years ago.That bit of evidence along with the discovery of the CMBR and of course the abundance of lighter elements, all point to the Universe evolving from a hotter, denser state about 13.8 billion years ago.
That said, my view of the composition of the CMB differs from existing theory. I developed my hypothesis in my thread (moved to Pseudoscience) called “At Rest with our Hubble View”. The thread turned ugly, but in a nutshell, my suspicion is that there is a contribution to the observable microwave background radiation from outside our arena.
Big Bang Theory with Inflation theorizes that surface of last scattering occurred 380,000 years after the big bang. Theory says that until then the opacity of the “arena” contained the photon energy and so no radiation escaped the expanding hot dense ball of energy. By that time the expanse of the space occupied by the contained photon energy had inflated and expanded much faster than the speed of light, and had cooled enough for atoms to form, lifting the opacity and releasing the photon energy. By that time the “universe” (arena in my lexicon) was so vast that when the opacity was lifted and the contained photons escaped, they started coming from all points far across that vast expanse and are still coming toward us from all directions today.
However, if the idea of preconditions to the big bang is considered as an alternative to “something from nothing”, or “God did it”, then the preexisting universe would be an alternative source to the inflowing radiation that we now observe filling our arena and still coming from all directions at every point in observable space.
That is my layman case for saying that part of the CMB is coming from preexisting space and out of a greater universe within which our Big Bang occurred. The consensus theory seems contrived to the extent that such a scenario is necessary to maintain the theory that everything began at the big bang (space, time and energy). My hypothesis is that our big bang was not the only active big bang event, and background energy coming into view from all directions might represent a background that is characteristic of a potentially infinite greater universe that has been characterized by a potentially infinite history of similar big bang type events all across the potentially infinite expanse.
Yes, the phrase, “As we know them”, leaves a huge opening for the “as yet unknown”, .I always like to talk of the BB bringing into existence/creating space and time "AS WE KNOW THEM". I see that as very important, and distinguishing from space and time, "AS WE DON'T KNOW THEM".
True, and the quantum foam is another part of the generally accepted quantum theory that contributes to the “weirdness” of QM. It is a way to address another aspect of the “as yet unknown”, and is common to many of the interpretations of the QM, I believe. It goes along with the case that non-locality is characterized by the probability function that allows an unobserved particle to take an infinite number of paths, or even may not physically exist until it is observed.This space and time "AS WE DON'T KNOW THEM" is often referred to as the quantum foam.
There is an alternative view, and I think it was really shoved to the back burner for a long time until some errors were found in the ideas of von Newmann. He presented a mathematical proof that had been generally accepted that said hidden variables could not work in the quantum world (see Hidden Variables in, “Q is for Quantum”, by Gribbin). It was John Bell that pointed out the simple error in von Newmann’s work.
Yes, to be sure. But we can be comforted by the fact that in science anything that appears Supernatural has natural causes that we just don’t yet understand (assuming that the scientific method excludes anything Supernatural).Well at least outside of time and space " AS WE KNOW THEM".
And of course any hypothesis so formed, including a divine omnipotent deity is outside the descriptive/predictive parameters of our current model of the BB and GR.
No, I am not hypothesizing the Oscillating theory of Universal evolution, though that is a common misunderstanding about my so called model. Note that the article I quoted from the DeepAstronomyBlog included this comment about the oscillating theory:It appears to me that you are hypothesizing "The Oscillating theory of Universal evolution, which was on level terms along with the BB and Steady State in the early fifties.
Two of those quickly fell out of favour with the Hubble expansion discovery, although the Oscillating theory would encompass the BB theory, but we do not have any evidence for any big crunch and then re-expansion.
And the recent discovery of the acceleration in the expansion rate, points to a recollapse as impossible.
DeepAstronomyBlog said:“Further, the idea of cyclical universes doesn't solve it either.
For reasons having to do with entropy and the second law of thermodynamics the process of an ever cycling universe - one that continually expands and contracts - cannot be perfectly efficient. This means that each successive expansion will take a little longer than the previous one.
If each previous universe is, say, half as long as the one that succeeds it, and the one before that half as long, this infinite sum does eventually converge to a universe with zero length with no obvious past and we are back again to at least one big bang starting for no obvious reason.”
I agree with his assessment. My view is of a landscape of big bangs; a potentially infinite number of active big bang arenas at any given point in time, playing out across a potentially infinite space.
I agree. Our ability to observe limits us in observing the details of nature at the micro and macro levels, but my so called model includes the hypothesis that as we improve our technology, as we have with the LHC for example, and with WMAP and the Planck Sky Survey, we will continue to push back the curtain.At this stage from what little I know, string theory, Quantum Loop Gravity and other derivatives seem to mathematically describe the Planck era/10-43 seconds after the initial event quite eloquently, but as yet we do not have the technology or know how of observing and/or measuring at those scales.
Yes, you should read Laura Mersini-Houghton’s paper called, “Is Eternal Inflation Eternal?”. http://arxiv-web3.library.cornell.edu/abs/1106.3542My pet hypothesis is as I have said before....Our BB was just one of a near infinite number to have arose out of fluctuations in the quantum foam....some of those fluctuations arose and collapsed again...others have expanded far to quickly and have burst, while our own Universe bubble continues.
