Snapshot · The Diary Of A CEO with Steven Bartlett
Tidal forces inside a black hole stretch a human body head-to-toe, then snap it into pieces — bifurcating 1 to 2 to 4 to 8 — while simultaneously extruding them through spacetime like toothpaste through a tube.

Tyson begins with a concept 10-year-olds can grasp — escape velocity — and builds systematically to the full horror of black holes. [1] — Neil deGrasse Tyson "Falling into a black hole, you'd watch the entire future history of the universe unfold in fast-forward due to time dilation. Then tidal fo…" 42:40 Earth's escape velocity is 7 miles per second; a black hole is simply any object where that threshold equals the speed of light. Cross the event horizon and there is no path in any direction that leads out — spacetime itself is folded back on itself. Inside, time dilation means the universe's future unfolds in fast-forward around you. Then come the tidal forces: the difference in gravity between your head and feet grows catastrophically. You are stretched, then snap at the base of your spine into two pieces — and you keep falling, bifurcating 1 to 2 to 4 to 8 all the way to the singularity. Simultaneously, you're being compressed laterally and extruded through the fabric of spacetime 'like toothpaste through a tube.' At the singularity itself, general relativity predicts infinite density and infinite smallness — a point where the equations themselves break down. Tyson closes by noting that general relativity actually predicts an entirely new spacetime opening up inside the black hole — a whole universe of its own.
A black hole isn't mysterious magic — it's any object where the escape velocity equals the speed of light, so nothing, not even light, can get out. The moment you cross the event horizon, there is no path in any direction that leads back out.
Earth's escape velocity is 7 miles per second; a black hole is an object where that threshold equals the speed of light, preventing anything — including light — from escaping.
Falling into a black hole, you'd watch the entire future history of the universe unfold in fast-forward due to time dilation. Then tidal forces would stretch and snap you into two pieces, then four, then eight, all the way to the singularity — while simultaneously extruding you like toothpaste through the fabric of spacetime.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
Even compounds that clear preclinical testing often fail in humans: 30 to 50% of drugs entering phase 1 trials do not advance to phase 2, frequently because human behavior differs from animal models.
More than 80% of published BPC-157 research comes from a single academic group whose researchers have IP and commercial interests connected to the molecule, limiting independent replication.
Roughly 100 peptide drugs are already FDA-approved, about 150 more are in clinical trials, and 600–700 are in preclinical development, underscoring the legitimacy of peptide science broadly.
The scientist who discovered BPC-157 refused to disclose the screening method used to identify the compound and has never fully published the parent protein sequence — what Peter Attia calls 'scientific trust me, bro.'
The brain's visual, auditory, and motor cortices light up nearly identically whether an experience is real or imagined, making visualization a form of actual neural training.
