Why did Einstein introduce the cosmological constant?
The usual story is that he wanted a static Universe.
But the actual motivation is more interesting, and involves a fundamental principle that has largely been forgotten.

Newton's laws allow objects to accelerate forever without consuming energy
In fact, two masses can orbit, collide, or accelerate together indefinitely
The reason we don't talk about this is much the same reason we can't travel faster than light

Ordinary, stable atoms can only exist in a Universe with 3 space dimensions
The argument is very straightforward:
Stability in atoms is a balance between kinetic energy and potential energy of the electrons

The 2026 Nobel Prize is the third prize for neutrino astrophysics, not the first. A visionary engineering achievement by a distinguished physicist and his team. With great potential. But...

Sci populists can’t hide the ball for 5 minutes.
What is the “benefit to humankind” of FTL alien telephones, superdeterminism and carrying water for bullshit artists like Eric Weinstein.
Shitting on productive physicists for the titillation of contrarians is the game here.

IceCube, high-energy neutrinos, and Francis Halzen win 2026’s Physics Nobel
A deep dive on the history and development of high-energy neutrino astrophysics.
Francis Halzen thoroughly deserves to be the first solo physics Nobel Laureate since 1992!

The man who just won the Nobel Prize for IceCube told me the truth: by every objective measure, physics is a miserable career.
The only reason to do it is obsession. Francis Halzen on the insecurity he carried for decades, why imagination can beat intelligence, and the Nobel logbook that made Barry Barish feel like an impostor next to Einstein. Full episode with @nobelprize winner Francis Halzen: youtu.be/cun1zuEQTVU

Ioannis Tsiokos, a software developer from Athens, credits his discovery of the first 3D “einstein” to GPT-6 Astra: “The 3D Einstein was found by Astra, not me. I have only understood the intuitive geometric argument of the proof, not the mathematics of it.”
