    Undergrad LHC To Announce Its Lepton Universality Violation Results On Tuesday (20-Dec-2022)

    The second to last paragraph of the most recent article linked in the linked source notes that the biggest discrepancy drops from 4.1 sigma to 0.2 sigma when the bin closest to the charm loops is removed from the analysis, and the charm loops aren't properly considered in this analysis...

    High School Can anyone deeply understand relativity?

    A frequently meaning of "using natural units" is to omit c=h=1 from the notation entirely.

    High School Can anyone deeply understand relativity?

    Strong disagree on this point. A novice should be meticulous about fully displaying all units and continue to do so until the person intuitively knows the units of everything in the equations being used. As a math and science tutor when I was in college (and afterwards), one of the most common...

    Studying Correlating IQ and STEM performance

    I think that you are almost surely wrong. When I first moved to Denver, I looked at detailed statistics about various kinds of educational outcomes at different high schools in the city. One of those was West High School which had the worst outcomes in the city. In particular, they tracked kids...

    Studying Correlating IQ and STEM performance

    My guess is that the OP is getting at something along the lines of the analysis of this paper (discussed further by one of the authors at the link below): Non-linear Psychometric Thresholds for Physics and Mathematics Stephen D.H. Hsu, James Schombert...

    Undergrad If gravity is emergent, how does this affect string theory and loop quantum gravity?

    SUSY also isn't just up against the LHC results. SUSY was touted as a source of a dark matter particle candidate, and SUSY dark matter particle candidates have been essentially ruled out. SUSY was touted as a source of a discrepancy between the experimental measurement of muon g-2 and the SM...

    Undergrad If gravity is emergent, how does this affect string theory and loop quantum gravity?

    Gravity is not emergent in M theory and F theory in the same sense that it is in entropic gravity theories, i.e. in M theory and F theory it is not the case that gravity flows logically from the other forces without a need for it to have a source of its own. Indeed, in some versions of these...

    Undergrad If gravity is emergent, how does this affect string theory and loop quantum gravity?

    There are emergent gravity theories that are intimately related to entropy concepts such as S. Shamari, A. Sheykhi, "Resolving Galactic and Cluster Dynamics Without Dark Matter: Tsallis Entropy as the Unique Foundation of Emergent Gravity" arXiv:2607.19435 (July 21, 2026) (see especially the...

    Undergrad Is infinity a necessary concept?

    Also worth mentioning that many significant aspects of mathematics involve finding ways to get results that avoid infinities, and in the applied mathematics of physics, some of the most important examples involve "renormalization" (in high energy physics/particle physics) and complex analysis...

    Announcement PF Style 2026

    Don't like the zero character having a slash. I understand the reason to distinguish the letter oh and the number zero, but it is too easy to misread as an eight in small fonts or at a distance.

    Announcement PF Style 2026

    Ugh! Not a fan of the forest green and earth tones. Also, the font used for "Today, 7:31 AM" in light gray, maybe Courier, is hard on the eyes. Disagree that it looks modern. More like early 1970s or retro sci-fi.

    Graduate Is the massless survivor of an SMG gapped phase genuinely chiral?

    Practicing physicists, in my experience, are almost always willing to discuss their papers and specialties with well-informed people.

    Graduate What is new with Koide sum rules?

    How do these papers fit into a larger research program of either of the authors?

    Graduate How valid is the Block Universe theory?

    To this extent, the block universe could arguably be disproven because in quantum gravity, which is not deterministic, neither the future nor the past is determined definitively by a specific slice of perfect data about the present (indeed, even perfect data about the present is theoretically...
