Keating answers what may be the deepest question in science: what happened before the Big Bang? He explains that the cosmic microwave background is the leftover heat of nuclear fusion at the universe's birth, still filling all of space as microwaves. To detect it without interference from atmospheric water vapor — which absorbs microwaves the way a microwave oven heats food — you need to go to Antarctica or Chile's Atacama Desert at 17,000 feet altitude. He describes four competing pre-Big Bang theories: Stephen Hawking's 'there is no before' (the South Pole analogy — you can't go south from the South Pole); the Big Crunch/Big Bang cycle; string theory's colliding membranes; and the multiverse. He notes that the Genesis model — a single, specific beginning of time — is the only one that sounds like 'In the beginning,' and that it's the only one with a falsifiable scientific signature: primordial gravitational waves detectable in the CMB.

Brian Keating's birth father abandoned him at age 7, choosing to waive child support rather than stay in his sons' lives. When Keating reconnected with him in graduate school and discovered they had independently pursued identical physics research, he set a singular goal: win the Nobel Prize his father never could. Partly for science. Partly for revenge.
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.'
