To all the #theoretical #physicists out there, here is a #question for you.
What #physical #dimension is #quantum?
A. Length.
B. Height.
C. Depth.
D. Volume.
The #answer is #depth because it reflects parallel space.

The Amazing History of #Locality in #Theoretical #Physics
#Philosopher #DavidAlbert rambles (his word) for ½ hour on the often gripping (and #funny) #saga of #nonlocality in #scientific #thought. Starting with #fish, he ushers us along to #Bell's #Theorem in the 1960s. It seems we are "inescapably" in the age of nonlocality. Perhaps an age of #TimeTravelers?

#Zoomposium interview with Prof. Dr. #Holger #Lyre": Conscious #structures or structures for #consciousness?"
A Zoomposium interview with Prof. Dr. Holger Lyre, renowned German philosopher of #science and professor of #theoretical #philosophy at the University of Magdeburg, where he has also been a member of the Center for #Behavioral #Brain #Sciences (CBBS) since 2010.

The #KrononautMoon Project is an ongoing series of community experiments to contact #TimeTravelers — as "in-person", but more likely via #quantum #signal. The next attempt is coming up soon on 14 Mar 2025 — under the #TotalLunarEclipse — wherever you are. These outreaches are sometimes referred to as "landing receptions", but call them or redesign them however you like. Following is a brief, all-true #chronology of such #events, going back 40+ years. The excerpt is from our detailed #article on Medium.com.
❛❛ #Future #intelligences would have the necessary transport #technology that is not yet existent in our #world. To date, there have been 5 recorded attempts of this method, with the most famous one devised by the late #theoretical #physicist #StephenHawking, in #Cambridge #UK on 2009 Jun 28.
Hawking referred to his get-together as a “reception”—what we now think of as a version type 1.0. His champagne toast to “tourists from the future” was, by no means, not the first of the prototypes, however, because it was staged years after 3 similar experimental attempts — stationed in different #countries and unrelated to each other. The professor’s cheeky soirée occurred four years after a rollicking party that was thrown for “Inhabitants of the Future” at Forrest Place, #Perth #AU, on 2005 Mar 31. Then, a few months later, an equally festive #TimeTraveler #Convention was hosted at #MIT — The #Massachusetts Institute of Technology, #Cambridge #MA #US, on 2005 May 07. These elaborate productions were preceded by a full two decades, back when a group identifying itself as the #Krononauts assembled in #Baltimore #MD #US (alt. spelling: #Chrononauts). That seminal event, which was covered by a #NewYorkTimes reporter, happened at a downtown #bookstore, under the light of a #FullMoon, and a multi-planetary #syzygy, on 1982 Mar 09.
More recently, in the spring of 2023, a dogged #podcaster for TheLastArchive.com and Pushkin.fm, published a riveting and droll #audio recounting of Baltimore’s Krononauts gathering, and then gave the concept a uniquely personal #experimental spin, noting the time and #GPS #coordinates. The effort successfully demonstrated that a single individual can attempt extra-temporal #contact on one’s own, equipped with little more than a #public #library #bench, and can meaningfully contribute to the corpus of #Community #Time #Travel #Research. ❜❜
On 2025 Mar 14, join your #friends, fellow #Mastodonians, and #TimeTravelers for an evening of #peace, #love, and #cosmic #tranquility, wherever you are.

@djb (Daniel J. Bernstein) tooted about a new blog post[1] he published. It's here:
https://blog.cr.yp.to/20250118-flight.html
It's interesting. He's a #mathematician and software guy that in more recent years has been known mostly for his work in #cryptography, #theoretical and #practical. You're probably using his #Curve25519 every day in your #communications.
I'm not a mathematician (by a long shot), but it's written in a pretty accessible manner - it's not #formulae and #turgid academic #prose.
The central point he's getting at, by my possibly-mistaken understanding of it, is that current "common sense" about when attacks against pre-quantum cryptography like #RSA (and therefore when post-quantum cryptography becomes critical) are badly mistaken - based on bad assumptions about how attacks work, how they're implemented, and on badly #extrapolating from those bad assumptions using logic that doesn't actually represent the way attacks are developed and become practical.
TL;DR is something along the lines of "#quantum cryptographic attacks against RSA will be practical sooner than most people think, and you should be deploying quantum-resistant cryptography now, not later".
It's worth reading if you're at all interested in #crypto and #security stuff.
He also mentions a project he's involved in that has been discussed separately, transparent post-quantum tunnelling for unmodified #server and #client #software. Link in post.
[1] Written more like a conference presentation, FWIW.
Theoretical Physicist Michael Vera is the author of 'The #Unified #Theory of #Energy'.
@michaelvera's work is available on the #web and as a #PDF.
Vera has been a gentle critic of The #KrononautMoon Project. We encourage all civil discourse. One's belief in Time Travel is not a prerequisite when attempting #contact with #TimeTravelers.

I love the fact that many of our science departments were founded because we thought deeply about stuff like time, stars, the origin of life, consciousness etc. and then some other smart people started to conduct experiments based on that philosophical thought. #metaphysics #theoretical-philosophy the problem of time(travel), when has something changes so much that its not the same thing anymore and and and… Philosophy is completely underrated. IMHO.

❛❛ #Civilizations need #energy to expand. You’ve probably heard of the #Kardashev scale, which classifies civilizations based on their ability to generate and use energy (if you’re interested, #humans are barely on the scale). A new paper has shaken up that scale ❜❜ (with ad 7 min.)

Did you know that #invisibility cloaks are #real?
From the 2nd c's Cap of Hades to #Marvel 's Invisible Woman, magic that renders one #invisible is a common theme in #mythology & #scifi.
In 2006, #theoretical #physicist John Pendry figured out that light could be bent around an object so that it renders it invisible.
This led to many advancements in metamaterial science, known as 'metamaterial cloaking'.
I've enjoyed this talk by Pendry: https://www.youtube.com/watch?v=VO6IrynhjKs [start: 4:43min]

#Theoretical #physicist Fred Alan Wolf on possibilities of Time Travel:
…❛❛ I believe that the mind … the sub #SpaceTime realm out of which I believe matter comes into being — according to my understanding of #quantum #physics — that realm is a #spaceless #timeless realm which means that it's like in a sense a place where closed timelike paths can emerge ❜❜…
