Can I ask a favour? Could you read this and tell me where you think my argument fails? If you’re not sure, but still think physicists are basically right about black holes, could you ask a theoretical physicist to explain what I’ve got wrong? I’d appreciate it. 🧪 ⚛️
Six decades of black-hole physics built on sand.
The fallacy: mistaking inevitability for actuality, ignoring GR’s most basic rule.

I hate this cover image, but couldn’t force DALL-E to draw it right. The bounces should be cycloidal, constantly decelerating, like parabolas strung together with sharp bounces between. AI wants to smooth it out. Can anyone fix it?

No, Professors Penrose, Steinhardt and Turok: Albert Einstein did NOT propose a cyclic cosmology
They’ve proven themselves fallible—not just capable of error, but of seeing what they want to see; inventing their own truth. Once you’ve seen that, can you ever trust it’s the only time?

Have you ever heard that Copernicus independently rediscovered heliocentrism and wasn’t aware of Aristarchus? Or that ancient Greeks rejected Aristarchus’s heliocentric model because they were unable to observe stellar parallax?
Both are false

Setting the Record Straight: How Copernicus Concealed His Debt to Aristarchus—and Claimed an Intellectual Priority He Knew Wasn’t His
There’s a prevailing myth in the history of science that Copernicus rediscovered heliocentrism independently—and that he had no real connection to Aristarchus, whose own theory was vague, obscure, …

Einstein gave us relativity. But what if he misunderstood its true meaning — and led generations of physicists astray? In this essay, I argue that he did exactly that. Curious whether you find the reasoning convincing.

Space-time is a powerful and useful map — but it isn’t reality itself. Building from first principles, I argue that space-time, as the sum of all events, literally cannot exist. Recognising this distinction clears up a century of conceptual confusion in physics.

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time. But what does it mean to say that space-time exists? What kind of thing is it — is space-time structure, substance or metaphor? Read here: buff.ly/fg3RmlO
