I thought I would add a serious reply.
I took an introductory astronomy class in college in the late 1980s with Robert K. Soberman, a real "renowned astronomer" who thought that the Big Bang theory was incorrect. Whenever I hear the term, I think of him.

A comment from the blog link you posted:
I’m glad that Brad and Brian made the points I wanted to make when I read this post. The cosmological background is more than a single point in favor of the Big Bang theory: (1) the blackbody shape (2) with small anisotropies (3) that DO correlate with observed large scale structure are three arguments in favor of the theory. On top of that, the synthesis of the right ratio of light elements depends on an exact difference of exponentially-decaying neutrons and quadratically-growing space which is very difficult to satisfy in alternate theories.
Without inflation, the Big Bang’s problems were theoretical, not experimental. The smallness of the anisotropies are consistent with observations of the large scale structure we see today (other factors matter more), but in inflationless Big Bang, not enough of the last-scattering sky was in thermal contact to guarantee such uniformity. It was also strange that the universe should be so spatially flat today, considering that any non-zero curvature will grow with time. Both of these are solved by inflation, “the patch on the Big Bang,” but they could have equally been solved by the much less satisfying “maybe the universe was born that way” (exactly zero curvature, uniform blackbody distribution). It’s not the observations that disagree.
Even before the bullet cluster image, there was evidence that the majority (not quite 100%) of dark matter was non-baryonic, but by spatially separating the dark matter and baryonic matter, that image made it much clearer.
The WMAP analysis is somehow able to extract the right proportions of baryonic and non-baryonic matter from the cosmic microwave background, but I don’t understand that in detail. Those proportions were first measured in the modern universe, so that would be a non-blind confirmation.
I’m not against re-thinking an established idea, especially since the Big Bang theory has two patches that aren’t satisfactorily-motivated yet: inflation and dark energy. But it’s dishonest to suggest that the observational evidence is much weaker than it is.10 -

This is an idea proposed by Roger Penrose. The CMB could be a map/guide created by intelligence from the previous universe.

We can't study this. It's truly impossible to study this regardless of how advanced our technology becomes in the future.

Any theory about the universe is just exercise for an energetic mind. Nothing will ever come of it. Humans are intrinsicaly subjective so comprehending infinity accurately is not possible. A beginning and/or an end doesn't have to exist. Big bang is just an extension of the old theory of the earth being the center of the universe.

red shift is inherent in “quasars”, not just a doppler shift

Im not sure i appreciate the inference sir.
*whips out telescope*
A celestron hubble d3000 no less. Would a fake astronomer have one of these badboys i ask you! We have had some great times together. The milf in the tower block a couple of km down the road springs to mind. She assumed she was safe from prying eyes high up on floor 52. Now shes famous on voyeurporn.com
