If MOND a₀ is connected to cosmological density (a₀ ∝ sqrt(ρ_c)), then a₀ must evolve with redshift as a₀(z) = a₀(0) × E(z), where E(z) = sqrt(Ω_m(1+z)³ + Ω_Λ).

I’m genuinely thrilled. There are rare moments in science when two long-standing puzzles suddenly seem to click into place at once. For me, this feels like one of them: the possibility that we may be seeing a common thread between high-T superconductivity and light-induced SC.

AI-generated papers should never be published.

Actually not just math, this is happening across almost every field. AI is collapsing the barrier to entry for research. What once required a PhD and years of training can now start much easier. We are moving toward a world where there is no “hard research”, but just unsolved problems. Big things are coming!

Terence Tao responding to a question on what advice he would give someone considering a career in math in 2026: 'Yeah, so we live in a time of change. It is, as I said, we live in a particularly unpredictable era. And I think things that we've taken for granted for centuries may not hold anymore. So, yeah, the way we... do everything, not just mathematics, will change. In many ways, I would prefer the much more boring, quiet era where things are much the same as they were 10 years ago, 20 years ago. But I think one just has to embrace that there's going to be a lot of change and that, you know, the things that you study, some of them may become obsolete or revolutionized, but some things will be retained. There'll be a lot of opportunities for things that you wouldn't be able to do before. So, I mean, in math, you previously had to basically go through years and years of education to be a math PhD before you could contribute to the frontier of math research. But now it's quite possible at the high school level or whatever, that you could get involved in a math project and actually make a real contribution because of all these AI tools and lean and everything else. So there'll be a lot of non-traditional opportunities to learn. So you need a very adaptable mindset. There'll be one for pursuing things just for curiosity, for playing around. And I mean, you still need to get your credentials. I mean, I think for a while it would still be important to sort of still go through traditional education and learn math and science and so forth the old-fashioned way for a while. Yeah, but you should also be open to very, very different ways of doing science, some of which don't exist yet. Yeah, so it's a scary time, but also very exciting.'

@BahramShakerin Sir if you like cosmic coordinators… what do you think of the zimmerman formula?

Discovered new physics and all of a sudden my Claude Code won’t run out of credits. Well isn’t that a coincidence!

@pjungar @Anthony_Bonato Yes but this isn’t fitting the data… it’s a derivation of cosmologic principals.. and it changes well.. everything
