After the Space-Time Cones, I'd like to share the bigger project behind it, the place where all of this geometry lives. 🌌 Have you ever seen the shadow of a four-dimensional shape? We can't see the 4th dimension directly. But we can see its shadows. A 3D cube held under a lamp casts a flat 2D shadow on the table. In the same way, a 4D shape casts a 3D shadow into our world. Flatten that again and you get a 2D pattern. That's what the Geometry Atlas is: a map of those shadows. 👉 https://allistarcenter.com/geometry-atlas.html What's inside Nine interactive models, each one you can rotate, zoom and look inside: 🔷 The six regular 4D polytopes, the 4D "cousins" of the Platonic solids: • the 5-cell, the 4D tetrahedron and the simplest 4D shape • the Tesseract, the 4D cube • the 16-cell, the 4D octahedron • the 24-cell, a shape that exists only in four dimensions, with no 3D equivalent • the 600-cell and the 120-cell, the largest and most complex of all, built entirely on the golden ratio 🔷 The 600-cell and 120-cell merged into one dual pair. A slider lets you grow one inside the other and watch the exact moment they lock together: when the 120-cell is φ times the 600-cell. 🔷 Nested Platonic solids and nested dual shells: tetrahedron, cube, octahedron, icosahedron and dodecahedron sitting inside one another, layer by layer, each touching the next at exact points. How you can explore them 🔄 Rotate in 3D, and on some models even rotate through the 4th dimension and watch the shadow turn itself inside out. 👁️ Look along the symmetry axes: vertex-first, cell-first, edge-first, face on, and 2-, 3-, 4- and 5-fold views. 🎨 Switch each shell on and off to see how the layers build up from the centre. 📏 Read every rod length in millimetres for the size you choose. Each model is also a parts list for building it physically from copper rods and hubs. The orthographic views: where it gets beautiful When you look straight down a symmetry axis, the 3D shadow flattens into an exact 2D pattern: rings within rings, stars within stars. The 600-cell even produces a 30-fold mandala.

Been heads-down in the lab for weeks instead of posting — long overdue for an update. Here's part of what's happened since I went quiet, more to come. Claude helped me calibrate and connect one of my VNAs to the PC software and run some tests. The cones showed an amazing S11 (Return Loss) at a resonant frequency of 2.85 MHz. Later, when using a Slayer circuit with a MOSFET, the LED got brighter at that same frequency — which independently confirmed the measurement. S11 tells you how much power sent into the antenna is actually absorbed versus reflected back to the source. You can see the numbers in the first image, and in the second image you can get a sense of what a value like -61 dB actually means in practice. The third image shows the Sierpinski gasket Merkabah. You can see multiple spikes with good S11, but they sit well above what a standard oscilloscope or signal generator can handle — most of that gear only works up to 80–90 MHz, so it's essentially blind above that range. I also need to rule out contamination from the leads sticking up off the coax cable, since they can act as a dipole antenna themselves and might be contributing to some of those spikes. Next, you can see I'm building crystal holders where I wind copper wire and arrange them symmetrically around the cone's equator, pulsing them that way. This isn't the final design yet. Working in Fusion 360 hasn't been easy for me, but I just discovered something amazing — using an MCP connection, I can actually talk to Claude Code, and it executes the parametric modeling for me, examines what I've already built, and suggests better designs and ideas. This could take things to a whole new level and finally help us build the structural elements for the big Space-Time Antenna — the parts that need to hold real weight and hold tight tolerances. The last few days I also learned something important about diodes. The ones I've been using aren't good above about 30 kHz. A diode doesn't switch off instantly when voltage reverses — it keeps conducting backward for a short window first. On the scope, that showed up as roughly 450 nanoseconds of "leakage" every cycle. At low frequency that's nothing, but at 1 MHz each full cycle is only 1000 nanoseconds long, so that dead zone eats up nearly half of it. And yet we were still getting some power transfer above 800 kHz despite that.

has anyone heard from Krasimi? Has he gone missing like other scientists?

Hey everyone 🌀 Some of you have asked to try the Tesseract, so here it is — consider this a soft launch, just for this community first. When you log in, you get 10 Mirrors as a gift — enough for one full report, completely free, no card needed. If you want to explore further after that, it's €2 per report (10 Mirrors), minimum purchase €10 (5 reports). Home: https://tesseract.allistarcenter.com/ The tool itself: https://tesseract.allistarcenter.com/tesseract How it works (read this first if you're new): https://tesseract.allistarcenter.com/how-it-works A few honest notes: I've had a lot of you reach out wanting to try this personally, and I want to be upfront — I can't be the bridge for everyone individually right now. This is exactly why I built it the way I did: you can log in and run it yourself, completely privately. If there's something you want to explore that you'd rather not share with me directly — a personal decision, something private, something you're still working out for yourself — that's genuinely fine. Nobody sees your intention or your report but you. This is still actively evolving. I'm shipping changes regularly — some of you have already seen the tool change shape week to week. If something feels rough, unclear, or breaks, please tell me. Your feedback on anything — the wording, the experience, a bug, an idea — genuinely shapes what gets built next. This isn't a finished product handed to you; it's something being built partly with you. One thing worth knowing going in: the Tesseract is a mirror, not an oracle. It doesn't predict or tell you what to do — it holds your intention across 26 independent perspectives and shows you where your own thinking converges, and where it doesn't. Read the "How it works" page before your first run — it takes two minutes and will make your one free report meaningfully better.

🎁 I've put together a step-by-step beginner tutorial (PDF attached below) that walks you through everything I wish someone had shown me on day one: ✅ The one settings switch that unlocks everything else ✅ How to build and publish your own website — no coding, just conversation ✅ How to make Claude create custom Skills for itself (this one changes everything) ✅ Setting up British English mode — written and spoken No jargon. Just follow the checklist on the last page and you'll be building within an hour. 🎟️ AND — I'm giving away ONE voucher for a free week of Claude Pro, which unlocks Claude Code (the tool I use to build everything you see here). To enter: download the PDF, try one thing from it, and comment below with what you built or set up. I'll pick the winner in 7 days. The tools are simple. What you point them at is what matters. 🔺 Gere is free trial for a week if you resonate https://claude.ai/referral/id9qoBQFqQ?s=android
