"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."
More than 80 years ago, Erwin Schrödinger, a theoretical…

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.

Ping-coincidence lattice "with a twist":
a "Null-Strut Wheel".
"Can this set of causal relations (with 8-fold rotational spatial symmetry) be found in a spacetime region of Schwarzschild geometry ?"
(PSE/q/845793)
(Enjoy it while it out-lasts the drive-by-assaulting ...)

The article doesn’t say too much, but is it surprising to find the universe may be more complicated than we currently think it is?

www.bbc.com#OnThisDay On March 20, 1916, Albert #Einstein submitted to the German scientific journal Annalen der Physik the final version of an article on "General Theory of #Relativity."
Today is International Day of #Happiness and World #SparrowDay.
physics, relativity
Ivette Fuentes, PhD is working on figuring out the relativity inside of fancy atomic clocks that work using entanglement. She says that they are getting precise enough now that it's noticeable, and that we might finally have a decent experiment to start looking at how quantum objects get affected by general relativity.

@syferdet@toad.socialBRAXTON: The only way for me, for us, to recover is to obliterate Voyager from the timeline. That way, none of the events that caused this illness will have occurred.
JANEWAY: What events?
BRAXTON: Thirty years of exile on twentieth century Earth. The temporal inversion in the Takara sector. The #Vikings winning the Super Bowl.
/ @syferdet@toad.socialWon't the crew of Voyager be surprised when they find the 29th century birth control pill dispenser hidden in a conduit?
/ @syferdet@toad.socialSeven desperately tries to tweet back to the 29th century, however Grok has become so sentient that it controls the time-space continuum.
/ @syferdet@toad.socialHave a look at our memecoin tracking board. It shows Rikercoin futures being manipulated by Quark Industries.
/ @syferdet@toad.social15:43? We quote times only in Freedom Units on Voyager!
It's 3:43 pm and you're going to report it as such.
/ @syferdet@toad.socialPARIS: Ping-Pong. You should try it, it's a great test of hand-eye coordination.
SEVEN: I don't require testing.
PARIS: Yeah, so the Doc tells me. A visual acuity index of ninety nine point six.
So, the Doctor violates the doctor-patient privacy by just blurting out random test scores of his patients.
/ @syferdet@toad.socialEither this is the last thing you see before that final swelling blackness collects your soul, or the TV's electronics are about to go.
/ @syferdet@toad.socialStarfleet ships of the future will have soundboards at every station so you can perfect that perfect mix tape.
/ @syferdet@toad.socialCareful, Captain. This is an experimental chair controlled by your mind. It was created by some dipstick named Elon.
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”
5/5
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…
