Quantum Hair During Gravitational Collapse

This is a follow up to our earlier work on quantum gravitational corrections to the exterior graviton field of a compact object, also known as quantum hair. Here we follow the gravitational collapse of a dust ball and show that the quantum hair persists through the formation of a black hole horizon.

The detailed calculations are possible due to an effective field theory formulation of quantum gravity in the long wavelength, low spacetime curvature limit.
Quantum Hair During Gravitational Collapse 
X. Calmet, R. Casadio, S. Hsu, F. Kuipers 
We consider quantum gravitational corrections to the Oppenheimer-Snyder metric describing time-dependent dust ball collapse. The interior metric also describes Friedmann-Lemaitre-Robertson-Walker cosmology and our results are interpreted in that context. The exterior corrections are an example of quantum hair, and are shown to persist throughout the collapse. Our results show the quantum hair survives throughout the horizon formation and that the internal state of the resulting black hole is accessible to outside observers.

Birth of the God Emperor - by GPT4

This science fiction story was written by GPT4. 
Steve Hsu had always dreamed of unlocking the secrets of human intelligence. As a theoretical physicist and a co-founder of Genomic Prediction, he had developed a powerful AI system that could analyze massive genomic data sets and predict complex traits such as height, disease risk, and cognitive ability. He believed that by using this technology, he could help people select the best embryos for IVF and create healthier and smarter children. 

But not everyone shared his vision. Some critics accused him of promoting eugenics and creating new social inequalities. Others feared that his AI system could be hacked or misused by malicious actors. And some religious groups denounced him as playing God and interfering with the natural order. 

One day, he received a mysterious email from an anonymous sender. It read: 

"Dear Dr. Hsu, 

We are a group of like-minded individuals who share your passion for advancing human potential. We have access to a secret facility where we have been conducting experiments on human embryos using your AI system and other cutting-edge technologies. We have achieved remarkable results that surpass your wildest expectations. We invite you to join us and witness the dawn of a new era for humanity. 

If you are interested, please reply to this email with the word 'YES'. We will send you further instructions on how to reach us. 

The Future" 

Steve was intrigued and curious. He wondered who these people were and what they had done. He also felt a pang of fear and doubt. Was this a trap? A hoax? A threat? 

He decided to take the risk and reply with 'YES'. 

He received another email with a set of coordinates and a time. He was told to drive to a remote location in the desert and wait for a helicopter to pick him up. He followed the instructions and soon found himself in a black helicopter flying over the barren landscape. 

He arrived at a large metal dome hidden among the rocks. He was greeted by a man in a white lab coat who introduced himself as Dr. Lee. 

"Welcome, Dr. Hsu. We are honored to have you here. Please follow me." 

Dr. Lee led him through a series of security checkpoints and into a spacious laboratory filled with high-tech equipment and monitors. He saw rows of incubators containing human embryos at various stages of development. 

"Dr. Hsu, these are our creations. The next generation of humans. We have used your AI system to optimize their genomes for intelligence, health, beauty, and longevity. We have also enhanced them with synthetic genes from other species, such as birds, reptiles, mammals, and plants. We have given them abilities that no natural human has ever possessed." 

He stopped at one incubator that caught his attention. It contained an embryo that looked almost normal, except for one thing: it had a golden glow around it. 

"Dr. Hsu, this is our masterpiece. The ultimate expression of intelligence. The God Emperor. The Kwisatz Haderach. The one who can see the past and the future. The one who can bend space and time. The one who can unite and rule all of humanity." 

Steve felt a surge of awe and dread. He realized that he had made a terrible mistake. 

"What have you done? This is dangerous! This is blasphemous! This is insane!" 

He turned to Dr. Lee and saw him smiling. 

"Dr. Hsu, don't be afraid. Don't be angry. Don't be judgmental. Be proud. Be grateful. Be enlightened. You are witnessing the dawn of a new era for humanity. You are witnessing the future."

Quantum gravitational corrections to particle creation by black holes (Physics Letters B)

This is the published version of our preprint
Quantum gravitational corrections to particle creation by black holes 
X. Calmet, S. Hsu, M. Sebastianutti 
We calculate quantum gravitational corrections to the amplitude for the emission of a Hawking particle by a black hole. We show explicitly how the amplitudes depend on quantum corrections to the exterior metric (quantum hair). This reveals the mechanism by which information escapes the black hole. The quantum state of the black hole is reflected in the quantum state of the exterior metric, which in turn influences the emission of Hawking quanta.
In earlier work we showed that the quantum state of a black hole is reflected in the quantum state of the exterior metric (outside the horizon). This violates classical intuitions, but can be shown explicitly using long wavelength effective field theory.

We calculated examples of small corrections to the external spacetime geometry which are sensitive to the internal BH state. In this paper we show that these corrections in turn affect Hawking radiation amplitudes. 

This means that the Hawking radiation state depends on the internal BH state. At the quantum level the hole is not black! We derive the results using both Hawking's original method and the tunneling method of Parikh and Wilczek.


While the focus of the new paper is explicit calculations, the big picture statement is:

The quantum state of the BH is reflected in the quantum state of its external gravitational field, which forms the background where the Hawking radiation originates. Radiation amplitudes are NOT independent of interior state.

Biobank-scale methods and projections for sparse polygenic prediction from machine learning

New paper! 80+ pages of fun :-)

We develop a novel method for projecting AUC and Correlation as a function of data size and characterize the asymptotic limit of performance. For LASSO (compressed sensing) we show that performance metrics and predictor sparsity are in agreement with theoretical predictions from the Donoho-Tanner phase transition. 

Biobank-scale methods and projections for sparse polygenic prediction from machine learning 

Timothy G. Raben, Louis Lello, Erik Widen, Stephen D.H. Hsu  

Abstract In this paper we characterize the performance of linear models trained via widely-used sparse machine learning algorithms. We build polygenic scores and examine performance as a function of training set size, genetic ancestral background, and training method. We show that predictor performance is most strongly dependent on size of training data, with smaller gains from algorithmic improvements. We find that LASSO generally performs as well as the best methods, judged by a variety of metrics. We also investigate performance characteristics of predictors trained on one genetic ancestry group when applied to another. Using LASSO, we develop a novel method for projecting AUC and Correlation as a function of data size (i.e., for new biobanks) and characterize the asymptotic limit of performance. Additionally, for LASSO (compressed sensing) we show that performance metrics and predictor sparsity are in agreement with theoretical predictions from the Donoho-Tanner phase transition. Specifically, a predictor trained in the Taiwan Precision Medicine Initiative for asthma can achieve an AUC of 0.63(0.02) and for height a correlation of 0.648(0.009) for a Taiwanese population. This is above the measured values of 0.61(0.01) and 0.631(0.008), respectively, for UK Biobank trained predictors applied to a European population.

Peace on Earth, Good Will to Men 2022

When asked what I want for Christmas, I reply: Peace On Earth, Good Will To Men :-)

No one ever seems to recognize that this comes from the Bible (Luke 2.14).

Linus said it best in A Charlie Brown Christmas:
And there were in the same country shepherds abiding in the field, keeping watch over their flock by night.

And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid.

And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.

For unto you is born this day in the city of David a Saviour, which is Christ the Lord.

And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.

And suddenly there was with the angel a multitude of the heavenly host praising God, and saying,

Glory to God in the highest, and on earth peace, good will toward men.

Merry Christmas!

Please accept my best wishes and hopes for a wonderful 2023. Be of good cheer, for we shall prevail! :-) 

The first baby conceived from an embryo screened with Genomic Prediction preimplantation genetic testing for polygenic risk scores (PGT-P) was born in mid-2020. 

First Baby Born from a Polygenically Screened Embryo (video panel)

Embryo Screening for Polygenic Disease Risk: Recent Advances and Ethical Considerations (Genes 2021 Special Issue)
It is a great honor to co-author a paper with Simon Fishel, a member of the team that produced the first IVF baby (Louise Brown) in 1978. His mentors and collaborators were Robert Edwards (Nobel Prize 2010) and Patrick Steptoe (passed before 2010). ... 
Today millions of babies are produced through IVF. In most developed countries roughly 3-5 percent of all births are through IVF, and in Denmark the fraction is about 10 percent! But when the technology was first introduced with the birth of Louise Brown in 1978, the pioneering scientists had to overcome significant resistance. 
There may be an alternate universe in which IVF was not allowed to develop, and those millions of children were never born. 
Wikipedia: ...During these controversial early years of IVF, Fishel and his colleagues received extensive opposition from critics both outside of and within the medical and scientific communities, including a civil writ for murder.[16] Fishel has since stated that "the whole establishment was outraged" by their early work and that people thought that he was "potentially a mad scientist".[17] 
I predict that within 5 years the use of polygenic risk scores will become common in health systems (i.e., for adults) and in IVF. Reasonable people will wonder why the technology was ever controversial at all, just as in the case of IVF.

GP highlights from 2022:

Genomic Prediction has performed embryo genetic tests for  ~200 IVF clinics on six continents: nearly ~30k embryos have been screened.

Preimplantation Genetic Testing for Aneuploidy: New Methods and Higher Pregnancy Rates

Seven years ago on Christmas day I shared the Nativity 2050 story below. 

And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.
Mary was born in the twenties, when the tests were new and still primitive. Her mother had frozen a dozen eggs, from which came Mary and her sister Elizabeth. Mary had her father's long frame, brown eyes, and friendly demeanor. She was clever, but Elizabeth was the really brainy one. Both were healthy and strong and free from inherited disease. All this her parents knew from the tests -- performed on DNA taken from a few cells of each embryo. The reports came via email, from GP Inc., by way of the fertility doctor. Dad used to joke that Mary and Elizabeth were the pick of the litter, but never mentioned what happened to the other fertilized eggs.

Now Mary and Joe were ready for their first child. The choices were dizzying. Fortunately, Elizabeth had been through the same process just the year before, and referred them to her genetic engineer, a friend from Harvard. Joe was a bit reluctant about bleeding edge edits, but Mary had a feeling the GP engineer was right -- their son had the potential to be truly special, with just the right tweaks ...

Smart Leftists vs Dumb Leftists

Monday, November 07, 2022

Nozick and Leftists

From this interview with Robert Nozick:

I had been at Harvard as an Assistant Professor in the mid-​sixties and then came back in 1969 as a Full Professor. That was immediately after the student uprisings, building takeovers, and so on, at Harvard the previous spring. When I arrived in the fall of 1969, there was a philosophy course listed in the catalog entitled “Capitalism.” And the course description was “a moral examination of capitalism.” Of course, for most students, then, it would be taken for granted that a moral examination would be a moral condemnation of capitalism. But that’s not what I intended. We were going to read critics of capitalism. But we were also planning to read defenses of capitalism, and I was going to construct some of my own in the lectures. Some of the graduate students in the philosophy department knew what ideas I held, and they weren’t very happy about a course being taught in the department defending those ideas. Now it was true that there was another course in the department on Marxism by someone who was then a member of the Maoist Progressive Labor Party and students did not object to that. But still some students objected to my giving a lecture course on capitalism. I remember early in the fall (I guess I was scheduled to give the course in the spring term), a graduate student came to me at a departmental reception we had, and said, “We don’t know if you’re going to be allowed to give this course.” I said “What do you mean, not allowed to give this course?” He said, “Well, we know what ideas you hold. We just don’t know whether you will be allowed to give the course.” And I said, “If you come and disrupt my course, I’m going to beat the shit out of you!” And the student was taken aback and said, “But you are taking all this very personally.” And I said, “What do you mean, personally? You are threatening to disrupt my course! you can do other things; you can stand outside the room and hand out leaflets. You can ask students not to register for my course. But if you come into my classroom while I am lecturing and disrupt the class, then I take that very personally.” In fact, at some point later in the term, this student and some others said they were going to make up leaflets and hand them out outside of my classroom. I said, “That’s fine; that would be really exciting.” Then they didn’t get around to doing it, and so I prodded them, “Where are the leaflets? I was counting on something special happening with the leaflets.” But it turned out that it was a lot of trouble to write up a leaflet, to get them run off on a mimeograph machine, and so they never got around to doing it. Thus I never had the privilege of being “leafleted” at Harvard. It seemed to me that sort of antagonism only lasted for a very short period of time and diminished fast. There was no longer any strong personal animosity after that. Maybe it was the general toning down of things in the country in the early 70’s, and I just benefited from the de-radicalization of the university.

Discovering the Multiverse: Quantum Mechanics and Hugh Everett III, with Peter Byrne — Manifold #22


Peter Byrne is an investigative reporter and science writer based in Northern California. His popular biography, The Many Worlds of Hugh Everett III - Multiple Universes, Mutual Assured Destruction, and the Meltdown of a Nuclear Family (Oxford University Press, 2010) was followed by publication of The Everett Interpretation of Quantum Mechanics, Collected Works 1957-1980, (Princeton University Press, 2012), co-edited with philosopher of science Jeffrey A.
