The media release refers to “time before the Big Bang.” The idea that time did not begin, for our purposes, with the Big Bang would be contested by some. That raises arrow-of-time issues.
Siegel: In order for inflation to end, that energy has to get converted into matter and radiation. The evidence strongly points to that happening some 13.8 billion years ago.
Actually, multiverse cosmology would make a starting point irrelevant or else subject to endless redefinition. Powell’s bookmark-able summary can’t address the problem, of course, but that’s precisely what the multiverse does. Facts no longer matter much because contradictory facts have equal status.
It’s quite clear that Siegel’s objection to the idea of a beginning to the universe is philosophical. Most of the nonsense one hears, generally, can be traced to unwillingness to admit that.
At Quanta: After two years of sparring, the groups have traced their technical disagreement to differing beliefs about how nature works.
Nearly everything that has failed about the Big Bang model has been added because of bad metaphysics, a refusal to accept the consequences of a beginning. The remaining pieces of the Big Bang model that are failing and which can’t be attributed to bad metaphysics, were added from sheer laziness.
All that said, faith in mathematics is better than faith in a lucky rabbit’s foot because the mathematics might make sense someday.
Compared to evidence-free claims about the multiverse, news about the filling in of the missing pieces of Big Bang cosmology attracts little attention. Could that be because, however well-attested, the Big Bang is unpopular among cosmologists? (Due, we are told, to its apparent theistic implications.)
Researcher: The lack of evidence of HeH+ caused some doubts whether we do understand the formation and destruction of this special molecule as well as we thought,’ Güsten tells Chemistry World. ‘This concern is gone now.’
Maybe the cosmologists who don’t like the theistic implications of the Big Bang can overthrow the current universe and appoint another one?
Dr Carol Wood of Wesleyan University (a student of Abraham Robinson who pioneered non-standard analysis 50+ years ago) has discussed the hyperreals in two Numberphile videos: First: Extended: Wenmackers may also be helpful: In effect, using Model Theory (thus a fair amount of protective hedging!) or other approaches, one may propose an “extension” of the […]
Two things many cosmologists would like to get rid of are the Big Bang and apparent fine-tuning of the universe. Telling a different story is difficult mainly due to lack of evidence for a different story but they can make do with discrepancies. But then maybe the years have made some of us cynical.
The WIMP (Weakly Interacting Massive particles) model has just not worked out: We understand how the Standard Model particles behave. We have solid predictions for how they should interact through all of the fundamental forces, and experimental confirmation of those theories. We also have extraordinary constraints on how they’re permitted to interact in a beyond-the-Standard-Model […]
Thank goodness we were never in any danger of running out of end-of-the-universe/world/world-as-we-know-it scenarios anyway.
“The big universe is a problem for Christianity” is a claim something like “They’re out there” (meaning ET). It has nothing to do with facts; it is pure social positioning (or posturing). As with the Cosmos’s series’s “artistic license to lie,” it is a way of indicating that their social position is so powerful that they can misrepresent people.
