[2504.01830] Is Lorentz invariance violation found?

https://arxiv.org/abs/2504.01830

> ...Very recently, the Carpet collaboration has completed the full data analysis, reporting further support for their previously detected photon now at ${\cal E} = 300^{+ 43}_{- 38} \, {\rm TeV}$, which manifestly clashes with conventional physics
...
> If confirmed by future observations our finding would represent the first positive result in quantum gravity phenomenology.

In order to create a superposition state, quantum particles must be cooled to just above absolute zero. Innsbruck physicists have now succeeded in realizing “hot Schrödinger cats” - which are, of course, still very cold

The market isn't crashing.

It's quantum and just wants to be at it's lowest energy state.

It sounds like Sabine Hossenfelder is inaccurately diagnosing (some) real problems (and some false ones) as being scientists' fault directly.
The problems are a capitalist (profit-focused) failure of resource allocation. This includes a structure of education that incentivises "work-ready" skills over critical analysis.
You don't need to be an expert! Literally just encouraged to try, fail, learn, and try again.
THAT is 'science' -- not the scientific method (precisely) nor the institution of scientific research on a given scale of human organisation.

Scientists use magnetic minerals, fossil records, and innovative mapping to reconstruct our planet's 4-billion-year geological #history. You can trace the movement of continents from ancient Pangea to today's landscape, explaining how our world has constantly reshaped itself.

Reclaiming the Land

Lava floods human-made infrastructure on Iceland’s Reykjanes peninsula in this aerial image from photographer Ael Kermarec. Protecting roads and buildings from lava flows is a formidable challenge, but it’s one that researchers are tackling. But the larger and faster the lava flow, the harder infrastructure is to protect. Sometimes our best efforts are simply overwhelmed by nature’s power. (Image credit: A. Kermarec/WNPA; via Colossal)

I'm a strong proponent of learning with others. Here are two examples from physics and coding of the advantages of cooperative learning.

ICYMI: Mathematician Hannah Fry's performs a #physics demonstration with thread and bricks! This elegant experiment shows how the same number of threads can either fail catastrophically or support heavy loads, depending on one simple factor. The #video explains the #engineering that keeps elevators safely suspended and bridges standing.

It's the time of the year in which I challenge my students of #physics in engineering in producing a "tomato battery", i.e. to reproduce on stage the basic functioning principle of a galvanic cell: a pair of suitable metals, an acid solution, and some connecting wires.

"one tomato" battery is not enough to generate the 1.5V tension needed for the small digital clock, so they have to realise a serie of two tomato batteries is needed.

"Mind-boggling" speed of quantum entanglement is measured for the first time

Poster Prize at the LIGO Virgo KAGRA Collaboration Meeting

Congratulations to our colleague Lorenzo Pompili! Lorenzo is a PhD student in the “Astrophysical and Cosmological Relativity” department at @mpi_grav in Potsdam. Last week he won the prize for the best poster in the “Theory” category at the March 2025 meeting of the @LIGO Virgo KAGRA collaboration in Melbourne, Australia.

His poster presented new tests of Einstein's general theory of relativity using gravitational waves from the final stage of a binary black hole merger. During this “ringdown”, the black hole settles into its final post-merger configuration and emits gravitational waves at specific frequencies.

If Einstein's theory is correct, these frequencies depend only on the black hole's mass and spin. By measuring the frequencies, it is possible to test for deviations from Einstein's theory.

It is a very dense black cat, so dense that it bends the space-time of the pillow.

Scientists managed to film how a black hole absorbs matter.

Calling all physical science #researchers! The application process is open for the 2025 SNOLAB Underground Science Institute lecture program. Come to #SNOLAB for the summer, work on your project and/or a project at the lab, and get access to academic training and hands-on workshops. This is aimed at graduate students and postdoctoral researchers.

We will start reviewing applications soon!
