"The most important thing in the next 3-4 years is data centers in space. In every way, data centers in space, from a first principles perspective, are superior to data centers on earth. In space, you can keep a satellite in the sun 24 hours a day. The sun is 30% more intense, which results in six times more irradiance than on Earth. So you don't need a battery. The cooling in these data centers is incredibly complicated. Space cooling is free. You just put a radiator on the dark side of the satellite. The only thing faster than a laser going through a fiber optic cable is a laser going through absolute vacuum. Link satellites with lasers, and you have a faster and more coherent network than any data center on Earth."

🚨They CANNOT SCAN kilometers into SOLID ROCK! That is what skeptics of the Khafre Project’s findings say, and they are correct to point out that Synthetic Aperture Radar (SAR) can't do this. They are also TOTALLY MISTAKEN, here is why: The Khafre team are not using conventional SAR imaging in the way critics assume. They are using a patented form of SAR Doppler Tomography, pioneered by Prof. Filippo Biondi. This is not simple surface imaging. It is a phase-coherent interferometric method that detects subtle Doppler frequency shifts caused by internal micro-vibrations within dense structures. Instead of trying to penetrate rock, it “listens” to tiny seismic vibrations in the stone. Biondi’s trick is to capture micro-motions. Tiny seismic or structural tremors slightly shift the radar’s frequency (Doppler effect). By analyzing these Doppler shifts across multiple SAR images, they can reconstruct a 3D tomographic image of what’s inside, like a CT-scan from space. Prof. Filippop Biondi's patent (PCT/EP2023/064345) explicitly describes processing “coherent vibrational Doppler information” in SAR to allow penetrating 3D imaging "over a depth of several kilometers". In other words, it effectively turns the radar into a spaceborne sonar, using Earth’s natural vibrations to “sound” the subsurface, something ordinary SAR can’t do. A peer-reviewed Remote Sensing paper describes using COSMO-SkyMed SAR data to map new shafts and chambers inside Khufu . This case study in a scientific journal shows the technique in action (with high-res 3D results!). Beyond pyramids, the technique has practical uses. For bridges and infrastructure, Biondi’s SAR Doppler method can extract a structure’s “vibration profile” from orbit. That profile highlights cracks or damage. In one study the team applied it to Italy’s Morandi Bridge before it collapsed, SAR-based vibration maps showed unusual energy spikes right at the failing pylon. They even imaged deep tunnels. The HarmonicSAR site reports they “detected for the first time the Gran-Sasso Physics Laboratory at 1.4 km below the Earth using SAR”. In other words, their tomography saw a known underground lab 1400 m under Italy! They’ve also done scans of mountain tunnels (San Gottardo). Biondi was co-author on a 2016 Scientific Reports paper tracking Iraq’s Mosul Dam instability via SAR. That study used spaceborne radar to measure tiny ground motions around the dam over time. It shows that SAR micro-motion techniques can monitor slow structural shifts on a large engineering project. In short, SAR Doppler Tomography isn’t ordinary radar, it’s like using satellites and the Earth’s own background hum to “see” underground. Think of it as applying a CT-scan or ultrasound-like method from orbit. It’s unconventional, but it’s patent-backed and has some peer-reviewed results.

This researcher just discovered 8 “huge structures” under the Pyramids in Egypt. They go over 1 km deep. And they connect to a massive hidden chamber deep underground. Filippo Biondi: “We have measurements … using a synthetic aperture radar.” “We are seeing huge structures that are connected to the base of the Khafre Pyramid.” “These structures are extending underneath for … approximately over one kilometer of depth.” “The structures are like tubes that are connected to the base of the pyramid.” “We are counting, at the moment, four plus four tubes that are descending underneath.” “They are connecting the top—so the base of the pyramid—to something that is located at the bottom.” “At the bottom, we probably have huge chambers, approximately 80 meters wide, and also of height 80 meters on the bottom.” “What we know now is this, there are these huge tubes that are descending underneath.” “And we have noticed that these tubes has a sort of spiral nature.” “Each tube has a core in the center, which … connects the spirals.” Jesse Michels Khafre Research Project SAR Technology

"I grew up in a locality in Ahmedabad, which is called Satellite. It was named there because ISRO was started in Ahmedabad due to Dr. Vikram Sarabhai. And all of the SAR satellites which were built in India, were built from Ahmedabad." Gaurav Seth, CEO & Founder at PierSight, on why he built a satellite company in Ahmedabad, not Bangalore, not Hyderabad. "If you want to start a space company in 2018, you'll have to do a capex of $10 million even to build a 3U satellite. We've raised total of $10 million so far. We've been able to launch an in-orbit demo satellite, build a product drone-based SAR. And also now we'll be able to launch our commercial satellite."

Ok, one more as I dream of doing this: > an amateur timelapse video taken by a tourist from ` plush and comfortable room on a space cruise, timelapse is as it orbits around saturn at a peculiar angle, at times you can see the reflection of the room, at other times the lights are off, it's from a gopro on a tripod mounted next to the window. in a timelapse fashion we see people moving around quickly in the background, no sound effects, just calm music You can tell it's amateur as they put the tripod on a sofa.

NEWS: Each new Starlink V3 satellite carries six space lasers moving 400 gigabits each The lasers connect the satellites to each other, forming a mesh in orbit that can route your data between almost any two points on Earth without touching the ground. Together they add up to a petabit-scale network, and the paths are redundant. If one link is busy or blocked, traffic reroutes through another satellite. This is why Starlink can work in the middle of an ocean or a desert. Data hops satellite to satellite by laser, then drops down only where it needs to. It is the same laser tech NASA just chose to beam 4K video from its Orion Moon spacecraft. (Source: Starlink, July 17)

In our last conversation, Gavin said data centers in space will be the most important thing in 3-4 years. He explains that means "racks in space" and thinks orbital compute will solve the watts shortage: "When people hear data centers in space, they picture a Pentagon-sized building in space. That's not what it is. A Blackwell rack weighs 3,000 pounds. It's eight feet high. Four feet deep. Three feet wide. It's racks in space. It has these solar wings that are probably 500 feet long on each side. You keep it in a Sun-synchronous orbit, so those solar panels are always in the sun. And then because it's in an exactly Sun-synchronous orbit, the radiator, which extends behind it for hundreds of feet is in the shade. You link these racks using lasers traveling through vacuum which are already on every Starlink. SpaceX operates the world's largest satellite fleet, which is 98 or 99% of all satellites in orbit. Every Starlink, they're cooling it today. I think Starlink V3 is going to operate at 20 kilowatts. A Blackwell rack is only 100 kilowatts. And people talk a lot about density. Well, if you're connecting the racks with lasers through vacuum, you can make the rack bigger physically. In space, there's all sorts of things that SpaceX can do. They also now operate the largest data center on Earth. I've spent a lot of time at Starbase over the years, and I've talked to a lot of SpaceX engineers. It is the most talented group of engineers on planet Earth, and they're very confident they have solved this."

Pakistan's PRSC-EO3: an unusual orbit for an optical satellite Radar tracking via Leonardo Avella. Processed via COMSPOC SSA. PRSC-EO3 (visualized in cyan) launched April 25, 2026 on a Long March 6. It's an optical imager — but its orbit is curious. Most optical LEO satellites use sun-synchronous orbits (~97-105° inclination), which provide consistent lighting for imaging. PRSC-EO3 is in a 38° inclined orbit instead. This sacrifices global coverage and consistent lighting, but increases revisit rates over a specific latitude band: 20-40°N. That's India, Kashmir, and Pakistan. Now consider PRSC-S1 (visualized in pink), Pakistan's SAR satellite launched July 2025, sitting in a 41° orbit. Similar inclination, similar altitude — but their RAANs are ~175° out of phase. When one passes over South Asia in daylight, the other passes in darkness. SAR works day and night. Optical needs sunlight. The geometry appears to allow complementary coverage. We ran the access analysis [Image 1]. The SAR sensor (unconstrained) and optical sensor (daytime-constrained) together provide repeatable revisit across day and night. The gaps left by one are filled by the other. Then there's PRSC-HS1 — a hyperspectral satellite in SSO [Image 2], capable of detecting camouflage and identifying materials from orbit. Optical shows you the picture. SAR shows you the picture at night and through weather. Hyperspectral tells you what you're looking at. Five remote sensing satellites in 16 months [Image 2]. All launched by China. All with orbits favoring South Asian coverage. The stated missions are civilian. The orbital architecture appears consistent with a multi-modal ISR constellation.

HOLY CRAP 🚨: Graham Hancock just dropped a devastating blow to mainstream archaeology with the Great Pyramid of Giza. “It’s a 6 million ton monument… more than 2 million individual blocks of stone.” “The Great Pyramid is aligned within 3/60ths of a single degree to true north… on a 6 million ton monument.” “It sits almost exactly on latitude 30 which is 1/3rd of the way between the north pole and the equator.” “And it incorporates the dimensions of the earth on a scale of 1 to 43,200 in its own dimensions.” “So if you take the height of the Great Pyramid and multiply it by 43,200… you get the polar radius of the earth. Measure the base perimeter of the Great Pyramid… multiply it by the same factor, 43,200, and you get the equatorial circumference of the Earth.” “Archaeologists know this. They say it’s a coincidence, total coincidence, just by chance.” “However, I could agree with them actually if the scale was not 1 to 43,200. But the fact that it’s 1 to 43,200 changes everything because that belongs to a sequence of numbers that is found in ancient mythology all around the world… multiples of the number 72… derive from… the precession of the equinoxes.”

🚨#BREAKING EGYPT STAIRCASES TO THE PRE FLOOD ERA as HUGE STRUCTURES are Discovered 2km BELOW Pyramid of Giza! Synthetic Aperture Radar Doppler Tomography Reveals Details of Undiscovered High-Resolution Internal Structure of the Great Pyramid of Giza A research team consisting of Corrado Malanga, Armando Mei, Filippo Biondi, and Nicole Ciccole has released new findings from a SAR (Synthetic Aperture Radar) scan conducted on the Giza Plateau, focusing specifically on the underground structures beneath the Khafre Pyramid. This work is part of the ongoing Khafre Research Project, which leverages advanced satellite technology to explore the site’s hidden architecture. A mysterious L-shaped structure has been observed underground in the western cemetery of Giza. Known as the Cemetery of the Nobles or the Cemetery of the Pyramid Builders, it is an ancient burial ground located on the western bank of the Nile River, near the famous Giza pyramids in Egypt. The team used remote sensing technology to detect remains in the underlying structure. This cemetery served as the final resting place for individuals who held significant roles in ancient Egyptian society, including officials, administrators, and artisans involved in the construction of the pyramids. To look for more remains in the area, the team used electrical resistivity tomography, a geophysical imaging technique used to investigate the subsurface properties of the Earth, such as the distribution of rocks, soils, groundwater, and man-made structures. It involves sending electrical currents into the ground and the resistance is measured to detect underlying structures. According to a report in LiveScience, an anomaly was observed roughly 6.5 feet beneath the surface indicating the presence of some structure. Further investigation revealed an L-shaped structure measuring at least 33 feet in length. According to a paper published in the journal Archaeological Prospection, the structure seems to have been filled with sand, which means it was backfilled after it was constructed. The team has begun excavation to find out what this mysterious structure is could be a mix of sand and gravel, or perhaps an air void, the team said. Experts speculate that the structure is not natural in formation given it has a sharp shape. Dating back to the Old Kingdom period (around 2600-2100 BCE), the Western Cemetery contains a vast array of tombs, mastabas (rectangular structures with flat roofs), and burial shafts. These structures vary in size and complexity, reflecting the social status and wealth of the deceased individuals. One of the most famous tombs in the Western Cemetery is that of Queen Hetepheres I, the mother of King Khufu (Cheops), the builder of the Great Pyramid of Giza. Discovered in 1925 by archaeologist George Reisner, her tomb contained a wealth of artefacts, including furniture, jewellery, and other personal belongings, providing valuable insights into ancient Egyptian funerary practices and royal life. A problem with synthetic aperture radar (SAR) is that, due to the poor penetrating action of electromagnetic waves inside solid bodies, the capability to observe inside distributed targets is precluded. Under these conditions, imaging action is provided only on the surface of distributed targets. The present work describes an imaging method based on the analysis of micro-movements on the Khnum-Khufu Pyramid, which are usually generated by background seismic waves. The results obtained prove to be very promising, as high-resolution full 3D tomographic imaging of the pyramid's interior and subsurface was achieved. Khnum-Khufu becomes transparent like a crystal when observed in the micro-movement domain. Based on this novelty, we have completely reconstructed internal objects, observing and measuring structures that have never been discovered before. The experimental results are estimated by processing series of SAR images from the second-generation ROBIN WESTENRA

This cemetery served as the final resting place for individuals who held significant roles in ancient Egyptian society, including officials, administrators, and artisans involved in the construction of the pyramids. To look for more remains in the area, the team used electrical resistivity tomography, a geophysical imaging technique used to investigate the subsurface properties of the Earth, such as the distribution of rocks, soils, groundwater, and man-made structures. It involves sending electrical currents into the ground and the resistance is measured to detect underlying structures. According to a report in LiveScience, an anomaly was observed roughly 6.5 feet beneath the surface indicating the presence of some structure. Further investigation revealed an L-shaped structure measuring at least 33 feet in length. According to a paper published in the journal Archaeological Prospection, the structure seems to have been filled with sand, which means it was backfilled after it was constructed. The team has begun excavation to find out what this mysterious structure is could be a mix of sand and gravel, or perhaps an air void, the team said. Experts speculate that the structure is not natural in formation given it has a sharp shape. Dating back to the Old Kingdom period (around 2600-2100 BCE), the Western Cemetery contains a vast array of tombs, mastabas (rectangular structures with flat roofs), and burial shafts. These structures vary in size and complexity, reflecting the social status and wealth of the deceased individuals. One of the most famous tombs in the Western Cemetery is that of Queen Hetepheres I, the mother of King Khufu (Cheops), the builder of the Great Pyramid of Giza. Discovered in 1925 by archaeologist George Reisner, her tomb contained a wealth of artefacts, including furniture, jewellery, and other personal belongings, providing valuable insights into ancient Egyptian funerary practices and royal life. A problem with synthetic aperture radar (SAR) is that, due to the poor penetrating action of electromagnetic waves inside solid bodies, the capability to observe inside distributed targets is precluded. Under these conditions, imaging action is provided only on the surface of distributed targets. The present work describes an imaging method based on the analysis of micro-movements on the Khnum-Khufu Pyramid, which are usually generated by background seismic waves. The results obtained prove to be very promising, as high-resolution full 3D tomographic imaging of the pyramid's interior and subsurface was achieved. Khnum-Khufu becomes transparent like a crystal when observed in the micro-movement domain. Based on this novelty, we have completely reconstructed internal objects, observing and measuring structures that have never been discovered before. The experimental results are estimated by processing series of SAR images from the second-generation ROBIN WESTENRA

Brian Cox is pointing at one dot. The dot is a galaxy with 100 billion stars. There are 200 billion more on the same map. The thin line at the top of that map represents a billion light-years. At the speed of light, it would take a billion years to cross that sliver. The math gets stranger. The observable universe holds roughly 30 sextillion stars. Every grain of sand on every beach on Earth combined is about 7.5 sextillion. The universe has 4x more stars than Earth has sand. The deeper number is which of those galaxies you can ever actually reach. Dark energy is accelerating cosmic expansion. Space itself is stretching faster than light can cross it. The cosmic event horizon sits at roughly 16 billion light-years from Earth. Anything past that is moving away from us faster than light can chase. We can see those galaxies because their photons left billions of years ago when the gap was small enough. We cannot reach them. We cannot send a signal. We cannot know what they look like now. 97% of the galaxies on Cox's map are already disconnected from our future. Visible artifacts of a past that has ended. Now look forward. In about 150 billion years, accelerating redshift will push every galaxy outside our Local Group beyond detection. Andromeda will have merged with the Milky Way. The other 199,999,999,999 galaxies will be invisible. Civilizations on planets around future stars will look up and see only one galaxy. Their telescopes will tell them the universe ends at the edge of the Local Group. They will not see cosmic background radiation. They will not observe expansion. They will not know about the Big Bang. The evidence will have receded past their light cone. Every astronomy textbook they could ever write would conclude the universe is small, static, and made of one galaxy. We exist in a 100-billion-year window where the universe is still legible. Before us, too hot, too dense, too young. After us, the lights go out one galaxy at a time. 30 sextillion stars on the map. A 100-billion-year window in which to read it. We exist inside the only overlap.

New lecture for the book! Nominally about synthetic data, but mostly is a walk through of the distillation literature from the Hinton 2015 paper to multi-teach on-policy distillation of today! At 7.4 hours of video in my post-training brain dump and counting :) It was fun to stare at the math long enough and talk through the 3-4 core changes that needed to be made to the original formulation to have on-policy distillation be ready for the mainstream like it is today (and in RL frameworks). Otherwise, I include a bit of a history lesson for how synthetic data generally slowly took over all post-training data research (it wasn't always the case)! Then I do some 101 review on constitutional AI, rubrics, and other popular methods. 00:00 The emergence of synthetic data 10:50 Background on teacher-student knowledge-distillation 24:47: On-policy distillation (OPD, MOPD, and OPSD) 37:11 Constitutional AI & AI Feedback 45:50 Rubrics as rewards & conclusions Ofc, watch on YouTube etc.

Elon Musk explains exactly how Space X's Mechazilla can catch the Super Heavy booster. On Sunday morning, Space X successfully caught a 20+ story tall rocket booster. "This is a custom-built tower with arms that are designed to catch the largest flying and heaviest flying object ever made and pluck it outta the air." "It'll weigh about 250 tons. We'll make that lighter over time." "So you got a couple hundred tons plummeting at more than half the speed of sound. So this thing is still coming in really fast." "When the engines land... it's gonna drop the velocity to basically zero and come in between the arms." "The arms will be wide, and as it's coming in, the arms will, will close, go flush against the side of the vehicle, and the vehicle will be descending through the arms." "The probability is uncertain, but it is above zero." Insane.

Bridgit Mendler on how Northwood is fixing the space economy's ground infrastructure problem: "The problem that we're solving is for every satellite, it requires a connection point back to Earth so that they can control the spacecraft." "That point of contact on Earth is called the ground infrastructure." "If you don't have it, you don't have a space mission." "It literally is just like a rock in space you're doing nothing with." "There was this whole boom around spacecraft manufacturing." "And interestingly what started becoming the longest pole in the tent was just getting the point of contact on the ground to connect with." "You could build a satellite and launch it faster than you could actually connect with it from the ground." "Which just seemed absurd." Bridgit Mendler with Erik Torenberg

Elon Musk built a second internet above the first one. Nobody asked him to. Thousands of satellites orbit at 550 kilometers. Moving at 25 times the speed of sound. Talking to each other through lasers in the vacuum of space. Musk: “Thousands of satellites providing low latency, high-speed internet throughout the world.” Before Starlink, satellite internet lived at 36,000 kilometers. Geostationary orbit. Signals traveling a tenth of the way to the moon before bouncing back. The lag made it barely functional. Musk dropped the altitude by 98%. One decision rewrote the physics of an entire industry. But the altitude wasn’t the real play. Musk: “There are laser links between the satellites. It forms a laser mesh. The satellites can communicate between each other and provide connectivity even if the cables are cut.” Every internet connection you’ve ever used runs through cables. Fiber optic lines buried in soil. Dragged across ocean floors. Threaded through chokepoints that every military maps before anything else. A single anchor drop can black out a country. An earthquake can sever a continent. The entire digital world hangs from threads in the mud. Musk built a network that doesn’t touch the ground. No cables. No trenches. No ocean floor. No single point of failure. A constellation of machines whispering to each other through light at the edge of the atmosphere. The men who tried before him weren’t fools. Gates backed Teledesic at the height of Microsoft’s power. Motorola built Iridium with the best engineers alive. Both paid someone else to reach orbit. Both went to zero. Musk owned the rocket. SpaceX made launch reusable. Built the satellites in-house. Flew them on its own rockets. Owned every inch of the chain from factory floor to orbit. That isn’t a cost advantage. It’s a moat no one can cross without first building a rocket company from scratch. Starlink passed 10 million subscribers as a side project. Every telecom executive on Earth watched it happen. Not one of them can explain the architecture underneath. They think he built a better satellite company. He built the only network that survives when the ground gives out. And the ground always gives out.

The cheapest place to put AI will be space. Elon Musk says solar panels in space produce 5 times more power than on the ground. No atmosphere, no clouds, no day-night cycle. No batteries needed. And critically, no permits. Scaling energy on Earth means fighting land use regulations, environmental reviews, and grid interconnection queues that take years. Space has none of that. The math gets wild fast. SpaceX could launch hundreds of gigawatts of AI compute into orbit annually. That's more compute than currently exists on Earth. Ten thousand Starship launches per year. One launch every hour. And you only need 20 to 30 ships to sustain that cadence. Earth gets about half a billionth of the Sun's total energy output. A millionth of the Sun's energy is 100,000 times all of civilization's current electricity production. The AI race is not a software race. It is a power plant race. And software people are about to get a very hard lesson in hardware.
