If the title alone doesn't make your head explode, read on.

"Gravity simulators1 are laboratory systems in which small excitations such as sound2 or surface waves3,4 behave as fields propagating on a curved spacetime geometry. The analogy between gravity and fluids requires vanishing viscosity2,3,4, a feature naturally realized in superfluids such as liquid helium or cold atomic clouds5,6,7,8. Such systems have been successful in verifying key predictions of quantum field theory in curved spacetime7,8,9,10,11. In particular, quantum simulations of rotating curved spacetimes indicative of astrophysical black holes require the realization of an extensive vortex flow12 in superfluid systems. Here we demonstrate that, despite the inherent instability of multiply quantized vortices13,14, a stationary giant quantum vortex can be stabilized in superfluid 4He."

Alas, while very interesting, none of this will translate to something on the shelf at the Home Depot anytime soon.

If you're fluent in this stuff you're way above my head.
Seriously...my father was a world renowned nuclear physicist and yet, when I try to parse any of what you just put down, I might as well try to translate Klingon into Ancient Sanskrit.

What are you trying to say? Why is this paper more interesting than any other recent one?

 

[Loulit01]

What Do We Want?
Time Travel!
When Do We Want It?
That's Irrelevant!

ROFL. Exactly... or relatively.

I got this in my feed. Most of them (papers) I can't access. It was incredibly dense and confusing, but the implications of it are very, very interesting - if many of the details are beyond my comprehension.

Quantum Mechanics fascinate me. They're like the very rich - they're not like you and me. Embedded in this paper are references to scores of other papers (most of which I also cannot access).

As some have speculated, there are implications for time travel, as well as other breakthroughs regarding the interrelationships of time, mass, energy and the shape and function of the universe. I was particularly (unintended pun) interested in the modeling of a black hole's operation through this methodology.

 

[Loulit01]

While I don't understand the abstract, I've watched several documentaries about quantum physics/mechanics that try to get a few key points across to barbarians like me. The one thing that constantly goes through my head when I watch them is, "Hey, it's not supposed to do that!"

I watched one that showed how Einstein was wrong in describing quantum entanglement as "spooky action at a distance." Einstein was proven wrong by a theorem/experiment conducted by John Stewart Bell. I was completed fascinated watching something I still struggle to understand.

I have figured out three things:
The speed of light is absolute and we cannot theorize anything traveling faster.
It's a bad idea to ponder how a particle can be in two places at once while you are stuck in traffic.
And...

"I do not like it, and I am sorry I ever had anything to do with it."
—Erwin Schrödinger

"You know nothing, Loulit01."

P.S. I like the F. Scott Fitzgerald reference.

[In my best Scotty voice] "Translating Sanskrit is easy. Reading Klingon, that's hard."

 

[bomberfox]

Whut?

 

[DCCougar]

Hmm. Interesting.

"Our research positions quantum liquids, particularly He  II, as promising contenders for finite-temperature, non-equilibrium quantum field theory simulations, marking a transformative shift from already established simulators in curved spacetimes."

Thus the holy grail of unifying, to some degree, quantum physics with General Relativity?

Penrose said ""Indeterminacy in quantum mechanics only arises when you perform what is called 'making a measurement' and that involves magnifying an event from the quantum level to the classical level."

Sounds like they are "magnifying an event from the quantum level to the classical level." They made no mention of the Heisenberg Uncertainty Principle....

It doesn't mean FTL....

Are you sure about that?

I am surely uncertain.

Yeah, I went there.... OR, maybe I didn't.

Who was your father?

Who was your father?

Peter H. Haas, Deputy Director - Defense Nuclear Agency.

Invented the RF Permeameter which revolutionized radio manufacturing, headed up the teams that developed pulsed power, teams that invented nuclear hardening for military and mission critical civilian electronic and electrical infrastructure, helped invent the pulse reactor, starting with the Aurora facility in Maryland, used in simulating nuclear weapons effects testing.

In memorium: Peter H. Haas, 1921-1986​

​

None of us three sons inherited his math and physics abilities.
I guess most of the brains get inherited from the mother's side, as was apparently the case with us.
All of us turned out to be more suited to creative and artistic abilities. Mom's side were all artists, cabinetmakers and wrought iron workers.

Funny thing is, when I watched the movie "Avalon", I noticed that Armin Mueller-Stahl ("Sam Kritchinsky") was the spitting image of my father, both in looks and accent.
It was as if my father had suddenly become an actor.

A fascinating family to be sure.

 

[bomberfox]

Again wat? Can someone explain this to me like im 5? The way the op is describing it is like word salad to me. What on earth is even a giant quantum vortex? The hell is a multiply quantized vortices? Just wat? Would Depak Chopra glom onto this? Does the article even know the definition of these terms?! Defining your terms is very important!

Ive seen a lot of quantum woo but this makes me question if this is above my pay grade or is it quantum woo.

 

[Mr Person]

This kind of thing makes me wish I spoke mathematics, the true language of reality.

But then I see this and wonder how many decades of study it'd take to get there....
