Hossenfelder’s clarifications will at least help us understand what we are all confused about.
Which says that if there are more holes than pigeons, some pigeons must share.
The black hole has always occupied a sort of space in the middle, between science and philosophy. It’s good to see that acknowledged. From ScienceDaily: Erik Curiel studied Philosophy as well as Theoretical Physics at Harvard University and the University of Chicago, and the primary aim of his current DFG-funded research project is to develop […]
Most of Novella’s piece has to do with people who seriously espouse a flat earth as opposed to people who check the box and go back to their Twitter feed, surely the vast majority. It won’t be fun when those people have responsible positions, imparting their knowledge of the world.
It’s not a job that needs doing, the editors say.
No, Sabine, you’re not crazy. But you live in crazymaking times. Cosmology has degenerated into the pursuit of cool nonsense like the multiverse via string theory. So much now seems to revolve around whether findings help or hurt the nonsense. Not about learning more about what is really happening here now.
Thank goodness we were never in any danger of running out of end-of-the-universe/world/world-as-we-know-it scenarios anyway.
In short, she is saying, the universe wasn’t supposed to be like this and that’s the basis for the current crisis in cosmology. One can always invent “falsifiable” theories but their falsifiability is not in itself a virtue; it is simply the basis for them being theories in science at all. The question of whether they should be pursued or funded is a quite different one.
Peter Woit doesn’t want to give up but he makes it clear that the options are narrow and expensive. Perhaps we are entering a period of decline when cosmology is about the multiverse rather than the Higgs boson.
From ScienceDaily: Earth most likely received the bulk of its carbon, nitrogen and other life-essential volatile elements from the planetary collision that created the moon more than 4.4 billion years ago, according to a new study by Rice University petrologists in the journal Science Advances. “From the study of primitive meteorites, scientists have long known […]
As a matter of fact, we don’t often hear the Higgs called the “God particle” now that it’s been clearly identified and given Peter Higgs’s name. That was more common before. It’s almost like something else is bothering Dorigo but we won’t speculate.
“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.
Sean Carroll, an avowed atheist in the “scientism” camp of Bill Nye and Jerry Coyne, has made a list of apologia for the Big Bang (hereafter BB). You might wonder why there needs to be any apology at all if, as he himself says, “We have overwhelming evidence that it is true.”
And afterwards, we find the math works. Sabine Hossenfelder author of Lost in Math: How Beauty Leads Physics Astray, asks us to consider what distinguishes a good problem in physics, hence in cosmology, from a trip through some interesting weeds.
Says a team of three Canadian physicists.
