    Here’s an article from Quanta Magazine on the subject. The universe is expanding, but no one can agree on exactly how fast.

    Thanks Mara  :good:

    The implications are so interesting that Fermilab front-man Don Lincoln felt moved to make a video explaining why “No, this does not disprove the theory about a Big Bang, but… “:

    Thanks very much for always keeping readers up to date and ahead of the learning curve, Nigel. Much appreciate your insights and leadings wrought from having a knowledgeable foot firmly in the scientific world and the other in the realm of revelation.

    But the video you linked is very disappointing. The title is a phony hook to sell the current obsession with the rate of universal expansion/contraction. At the 5:33 minute mark, the grinning professor says: “Nobody seriously questions that the universe began 14 billion years ago, and has been expanding  since. The evidence is simply overwhelming.” The scientific arrogance makes me mad all over. That terrible assumption is why I, and probably many others, jeer at the findings and pronouncements of the astro-physics community, claiming as it does, absolutely irrevocably, that the whole universe was once smaller than a sesame seed. That’s utterly, completely, and totally ridiculous, even to we the base and ignorant hoi-polloi.

    If the non-physicist world could conceive, or even cared one whit about, what’s being taught by cosmic scientists, there might be more push-back. We’re relying on you the insider, Nigel. And a fine job you’re doing, and without igniting an unholy war on the UB. (See Nigel’s many and excellent Youtube presentations here: https://www.youtube.com/results?search_query=nigel+nunn&sp=6gMA

    Questions: (Maybe you’ve answered this before, on the old Forum, can’t recall.) What does the AP community reply when asked, “In which constellation did the Big Bang occur? Where was this presumed source and center of the physical universe located?”

    Hi Rick,

    I think this is why “slow and steady” is the name of the game. As long as we are susceptible to such irritations…  ;-)
