A Physics Professor Bet Me $10,000 I’m Wrong…

September 2nd, 2026

A UCLA Physics Professor bet me $10,000 that my video (https://youtu.be/jyQwgBAaBag) about going downwind faster than the wind was wrong.

Here’s how we proved it…

JWST May Have Discovered a New Cosmic Object: The Black Hole Star

August 27th, 2026

Gigantic black holes existed in a cosmic eyeblink after the Big Bang. That should be impossible. The James Webb Space Telescope has either made the problem much worse, or solved it by discovering the first Black Hole Star.

It’s impossible to choose a number at random

August 24th, 2026

In math you can’t truly pick things at random because formulas always give the same result.

So if we can’t pick randomly, how do we select anything in math?

Tesla just posted its best second-quarter deliveries ever — beating Wall Street’s ~409,000 estimate by about 20% — while US EV sales fell 20% after the $7,500 federal tax credit vanished. The tell isn’t the cars; it’s 1.48 million active FSD subscribers (up 56% year-over-year) and more than 55% of new North American Teslas leaving with FSD at delivery. Motor Trend flipped from calling the system exhausting in 2025 to naming FSD v14 the best driver-assistance product for 2026. I walk through why that turns a Model 3/Y into a transportation unit competitors can’t copy with a supplier part, and why Cybercab plus unsupervised software is the actual industrial bet.

ChatGPT can take two seconds or two hours and nobody dies — but a self-driving car or humanoid that hesitates the same way is a life-or-death failure. The next wave isn’t a bigger language model; it’s world models that watch video, remember 3D space, simulate physics, and act in real time under a battery power budget. I walk through why today’s chips were built for raw arithmetic, not memory and data movement, and what DeepMind’s Genie 3, Meta’s V-JEPA 2, and Microsoft’s Mirage are actually proving about the hardware physical AI still doesn’t have.
