"This work connects the dots among the great pillars of twentieth century #physics #thermodynamics, #relativity, and #quantummechanics—for a major paradigm shift…implications of quantum information processing in wetware at ambient temperatures," said Kurian.

"Physicists and cosmologists should wrestle with these findings, especially as they consider the origins of life on Earth and elsewhere in the habitable universe, evolving in concert with the electromagnetic field."

phys.orgPhysicist revisits the computational limits of life and Schrödinger's essential question in the era of quantum computingMore than 80 years ago, Erwin Schrödinger, a theoretical physicist steeped in the philosophy of Schopenhauer and the Upanishads, delivered a series of public lectures at Trinity College, Dublin, which eventually came to be published in 1944 under the title "What is Life?"

Back in 1915, Einstein put forth his most ambitious idea: the general theory of relativity, combining #gravity with #relativity to create an entirely new conception of our #Universe.

In most conventional circumstances, the predictions of Einstein’s theory are indistinguishable from that of its predecessor: Newton’s law of universal gravitation.

Is it possible, then, to somehow reduce Einstein’s equations down to Newton’s equations?

🚨 Postdoctoral positions in Computational Relativistic Astrophysics at our Potsdam institute 🚨

The “Computational Relativistic Astrophysics” department at the @mpi_grav in Potsdam led by Masaru Shibata announces the opening of postdoc appointments (2 years).

The department is currently composed of two group leaders, one senior scientist, and several postdoc researchers and students.

It focuses on several research topics in relativistic computational astrophysics including neutron star merger, collapsar, stellar core collapse and explosion, formation of supermassive black holes, and multi-messenger astronomy.

To be fair, though, I must add that the LLM even mentioned the usual caveats here. But these may not have been understood by the person:

“requires rigorous mathematical formulation and testing - currently speculative without such validation”

“a tall order needing extensive proof”

“a hypothesis awaiting the hard test of evidence”

After all, what could possibly go wrong when non-physicists pour their “physics buzzword bingo” with questions that sound like physics (but are not) into an LLM that ultimately doesn't understand physics either?

If the LLM then says, among other things, “it does seem almost too logical and elegant to be completely wrong”, this is of course problematic. Especially if the person at that point decides not to listen to any experts at all…

My objection that the central definition underlyinig the “theory” is not physical and ambiguous was completely ignored.

Worse still: because I was perceived to be to “stupid” has led the person to conclude that they will only discuss this with AIs in the future because “it obviously doesn't make sense (anymore) to discuss it with physicists.”

That's probably a problem.

Often they have become so bogged down in their pseudo theories that it is almost impossible to have a meaningful discussion with them.

Sometimes you can try and present a well-reasoned objection. Whether the other side will get it, is a different question.

Recently, I had the case that the person had “discussed” their theory with an AI / LLM beforehand and, due to “praise” from the language model, was convinced that they *could not be wrong*.
