There are multiple independent observations pointing toward dark matter:

1. Galaxy rotation curves. 2. Galaxy cluster mass measurements from gravitational lenses and infrared. 3. Cosmic Microwave Background models (mass measurements from inhomogeneities that correspond to acoustic waves, for eg).

MOND only explains 1.

Dark matter accounts for all 3. Only catch is that it hasnt been directly observed.

From Terry Tao's comments in the thread:

"Very nice! ... actually the thing that impresses me more than the proof method is the avoidance of errors, such as making mistakes with interchanges of limits or quantifiers (which is the main pitfall to avoid here). Previous generations of LLMs would almost certainly have fumbled these delicate issues.

...

I am going ahead and placing this result on the wiki as a Section 1 result (perhaps the most unambiguous instance of such, to date)"

The pace of change in math is going to be something to watch closely. Many minor theorems will fall. Next major milestone: Can LLMs generate useful abstractions?

Underrated even among physicists. Among the immediate post war generation his contributions are up there with Feynman and Schwinger.

To quote Freeman Dyson: "Professor Yang is, after Einstein and Dirac, the preeminent stylist of the 20th century physics. From his early days as a student in China to his later years as the sage of Stony Brook, he has always been guided in his thinking by a love of exact analysis and formal mathematical beauty. This love led him to his most profound and original contribution to physics, the discovery with Robert Mills of non-Abelian gauge fields. With the passage of time, his discovery of non-Abelian gauge fields is gradually emerging as a greater and more important event than the spectacular discovery of parity non-conservation which earned him the Nobel Prize."

Plausible. General Relativity was concieved by an extraordinary genius, but the perihelion of mercury was measured by dozens of painstaking but otherwise unexceptional people. Without that fantastically accurate measurement, GR would never have been accepted as a valid theory.

There should be legal recourse against these companies and investors. It is pure crime to release such obviously broken software.

The standard model is 100% quantum mechanics. It's just QM as applied to fields. While undergrads start with single or few particle quantum mechanics.

There is a lot of hard math and fundamental physical ideas that pop out when we apply quantum mechanics to fields, but it's still QM.

The work of Heisenberg, Schrodinger, Dirac, Pauli from 1925-28 or so is absolutely not our date.

Killian civilians in war has been completely normalized. Even in highly visible conflicts in Gaza and Ukraine. People just shrug and move on.

Political discourse has lost all sense of decency. Senators, the VP and POTUS all routinely mock and demean their opponents and laugh even at murder. Arrests are made by unknown masked men with assault rifles.

AI is simply irrelevant to this - humans are selfish, tribal and ugly.

The Democratic Governor of California denounced them publicly and stopped the effort.

Despite Musk raising millions and campaigning viciously against the Democrats the administration kept all of SpaceX contracts and Tesla ev subsidies. In fact the IRA benefited Tesla disproportionately.

Both sides are NOT the same. One is fascist and the other is not

Yes, both parties do it. In California for example left-wing politics is openly racist and I have sympathy for even the crazy republicans here.

However to defend Obama - he explictly ran on unity and went out of his away to not openly benefit his own race.

Fine, I don't disagree with anything you point out. However where we differ is that I believe identity politics is the trigger factor here, all the other changes you mention (loss of balance of power etc) are downstream of this.

Low-level corruption at the local/state level is related but its effects are different though. In fact even today low level corruption in the US is extremely low by global standards - you can't bribe your way to a drivers license openly, for example. I'm sure it happens but it's not common or openly boasted about (parts of CA or DC could be an exception).

Here the corruption is openly displayed as a kind of peacock-tail to the beneficiaries.

It turns out that when elections are fought on the basis of identity (race, religion) etc corruption is actually considered a benefit! This is because the loyalists interpret this as "we" are winning and "they" are losing.

I witnessed this up close in India where parties openly exist to benefit certain constituencies based on caste, language, religion and so on.

It is horrifying to see this attitude take root in my adopted land.

Apart from Einstein, Heisenberg, Dirac, Pauli, Bohr and Fermi are clearly ahead in depth and breadth of contribution. Post-war it's less clear, but IMO Steven Weinberg and Murray Gell Mann are probably greater.

This analysis in the end doesn't show what it claims to show and actually proves the reverse - US Health care spending is much larger than other countries, it eats up significant fraction of productivity gains in other sectors (rises faster than income as shown by the 1.8 slope in the very first graph), and does not lead to better health outcomes. It actually proves we would be better off if we spent less and focused on lifestyle.
