Snapshot · The Diary Of A CEO with Steven Bartlett
Objects in low Earth orbit travel at roughly 17,000 miles per hour — making even a fleck of paint carry the destructive force of a rifle bullet or exploding grenade.

The conversation shifts to the growing congestion in low Earth orbit. Steven Bartlett notes that roughly 5,000 new satellite objects were launched in 2025 alone, and Tyson confirms SpaceX's Starlink constellation reached 10,510 as of the mid-2026 recording. The economic justification is real — GPS underpins Uber's entire business model, and Starlink brings high-speed internet to remote regions — but the risks are mounting. [1] — Neil deGrasse Tyson "If enough satellites crowd low Earth orbit and one is destroyed, the resulting debris traveling at 17,000 mph will strike other satellites,…" 58:00 Tyson explains Kessler Syndrome, first described in 1978: past a critical density threshold, a single satellite collision creates debris traveling at 17,000 mph — far faster than a rifle bullet — which strikes other satellites, each breaking into ten pieces, cascading until 100% of satellites could be destroyed. Four nations (China, India, Russia, and the US) have already demonstrated anti-satellite weapons. The movie Gravity, Tyson notes, portrays exactly this scenario. The future of astronomy, he concludes, lies in space-based or lunar telescopes precisely to escape this problem.
The widely cited ego-depletion model — the idea that willpower is a finite resource that gets depleted — failed to replicate in follow-up studies.
Humans are estimated to have 5,000–7,000 thoughts per day, yet can recall essentially none of them afterward, highlighting why in-the-moment emotional tracking matters.
A large Harvard study found that a wandering mind is an unhappy mind — people report greater happiness when their attention is tethered to the present, even if the task is unpleasant.
A key study finding that we have a 'credit card's worth of plastic' in our bodies was likely skewed because researchers used nitrile gloves that shed plastic particles onto the microplastic detector.
Emotionally sensitive people have a hyperactive amygdala, an underactive prefrontal cortex, and a frayed connection between the two — making emotional regulation structurally harder.
Rejection sensitivity can be observed as early as age 2 or 3, suggesting it has strong developmental and likely genetic roots.
A Yale study found that non-judgmental observation of emotions — without rushing to resolve them — reduces activation in the brain, making it a powerful regulation tool.
Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Barry Schwartz's research found that maximizers — people who try to optimize every decision — tend to achieve objectively better outcomes but report lower happiness than satisficers who choose 'good enough.'
