Snapshot · The Diary Of A CEO with Steven Bartlett
Everything humanity knows — biology, chemistry, physics, food — accounts for only 5% of what drives the universe; dark matter and dark energy make up the rest.

Asked to explain the Big Bang as if to a 12-year-old, Tyson obliges. Approximately 13.8 billion years ago, everything in the universe began as an infinitesimal, extremely hot point. [1] — Neil deGrasse Tyson "Dark matter + dark energy = 95% of universe: Everything humanity knows — biology, chemistry, physics, food — accounts for only 5% of what d…" 23:38 Energy and matter are interchangeable via Einstein's E=mc² (established in 1905), so as the hot fireball expanded and cooled, energy condensed into matter. Stars and galaxies formed over vast timescales, and the expansion continues today. But here's the humbling part: dark energy — a pressure in the vacuum of space causing the expansion to accelerate rather than slow — won a Nobel Prize in 1998 when its discovery overturned all predictions. Combined with dark matter (unexplained gravitational sources), these two unknowns constitute 95% of what drives the universe. Everything humanity has ever studied — every particle, molecule, organism, force — is just the remaining 5%. Tyson proposes renaming them 'Fred' and 'Wilma' since we have essentially no idea what either actually is.
The Big Bang occurred approximately 13.8 billion years ago, creating all space, time and matter in our universe from an infinitesimal point of energy.
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.
