syl, I am a big fan of hawkings for sure and have studied astronomy and cosmology for over thirty years.
Just fyi, the light left over from the biug bang if you have never seen this, before any stars existed at all.
The big bang is falsifiable by the way.

The theory of evolution is supported by all the sciences and confirmed with dna and all the evidence.
a joint statement of IAP by 68 national and international science academies lists as established scientific fact that Earth is approximately 4.6 billion years old and has undergone continual change; that life, according to the evidence of earliest fossils, appeared on Earth at least 3.8 billion years ago and has subsequently taken many forms, all of which continue to evolve; and that the genetic code of all organisms living today, including humans, clearly indicates their common primordial origin
Of course we are off topic here, but figured I would show you the wmap info if you have never seen it as it is extremely cool.
Neither the big bang or evolution will likely shown to be wrong, but will take on additional information as we get better with our technology. There pretty well supported substantially.
"It will be interesting to see how the SIBO dialog evolves over the next few years."
What has been interesting is Pimnetal writing a book it is the cause of IBS, using an inaccurate test in the intial studies that showed a high percentage and when they used better testing it showed a much much lower percentage. What is important is some people have both and the study of colonic bacteria in general and its effects on IBS and on other disorders. But again people can have IBS and not have sibo and people can have sibo for a variety of reasons. SIBO is a consequence of another problem. Like altered motility, so what causes the altered motility. But then there is viceral hypersensivity and brain gut axis dysfuntion as well.
Take a look at this thread and the posts to it.

Introduction
In this second installment in our quarterly literature review series on topical issues in irritable bowel syndrome (IBS) and chronic constipation, 3 original research studies are reviewed. These reports describe new information regarding the pathophysiology of IBS, the role of alternative therapies in the treatment of IBS, and the treatment of constipation."
"Lawal A, Kern M, Sidhu H, Hofmann C, Shaker R. Novel evidence for hypersensitivity of visceral sensory neural circuitry in irritable bowel syndrome patients. Gastroenterology. 2006;130:26-33.
The pathophysiology of IBS involves multiple underlying factors, including abnormalities in visceral sensation, disturbances in gut motility, and differences in the central nervous system (CNS) processing of visceral pain.[1] Many investigators now believe that visceral hypersensitivity is the most important pathophysiologic abnormality in IBS patients. The mechanism that leads to visceral hypersensitivity in patients with IBS is unknown, although current theories postulate the presence of abnormal sensory receptors and sensory afferents, deficient descending modulating factors, and a hypervigilant CNS. This latter component has been demonstrated in studies using functional magnetic resonance imaging (fMRI) and positron emission tomography scans.[2,3] The end result is that IBS patients sense abdominal discomfort at lower levels than normal individuals and often misinterpret normal sensations as painful (allodynia).[4] This has been demonstrated in a number of studies that typically involve distending the lumen of the gastrointestinal tract with a balloon.[5] One concern is that these studies may be influenced by cognitive processes associated with perceived sensory stimulation. Stated another way, anticipation of a possibly unpleasant sensation (balloon distention of the rectum) may alter cortical activity and thus change fMRI findings. Lawal and colleagues[6] addressed this potentially confounding factor by evaluating visceral sensation in IBS patients using subliminal stimulation."
"This well-designed, novel study is the first to show that very low levels of distention in the gastrointestinal tract, without any related cognitive processes typically associated with perceived distention, lead to increased CNS activity in IBS patients compared with healthy volunteers. In addition, patients with IBS demonstrated a maximum response to subliminal distention, as compared with the graded response seen in healthy volunteers. These findings are important for a number of reasons. One, it confirms the now widely accepted view that the brain-gut axis is a critical component in IBS. Two, it emphasizes that hypersensitivity is a key underlying pathophysiologic mechanism in the generation of symptoms in IBS patients. And finally, although not evaluated in this study, these findings point out that therapeutic options for patients with IBS should focus on treating both the hypersensitive gut and the hypersensitive CNS."
