Making Science Cool, with Jeff Goldblum

What It Covers

Neil deGrasse Tyson interviews Jeff Goldblum about portraying scientists in film, exploring chaos theory, de-extinction ethics, planetary defense against asteroids, and whether humanity should resurrect extinct species or contact potentially hostile alien civilizations.

Key Questions Answered

• •Chaos Theory Applications: Small initial condition changes in deterministic systems produce vastly different outcomes—the butterfly effect applies to weather patterns, economics, heart rhythms, and personal life decisions where minor choices create unpredictable long-term consequences across multiple domains.
• •De-Extinction Limitations: Ancient DNA degrades completely after one million years, making dinosaur resurrection impossible. Woolly mammoths died 10,000 years ago within DNA recovery range, but scientists debate whether humans owe extinct species resurrection if our ancestors caused their extinction.
• •Planetary Defense Gaps: NASA has catalogued most kilometer-sized asteroids capable of global extinction, but two-thirds of 25,000 regional-impact asteroids (140 meters plus) remain undetected. The DART mission tests kinetic deflection techniques, though funding prioritizes detection over deflection capabilities.
• •Extinction Pattern Complexity: Five major mass extinctions show no consistent asteroid correlation—some large impacts caused no extinctions while major die-offs occurred without impact evidence. Current research points to supervolcano eruptions releasing toxic gases as primary extinction drivers, not extraterrestrial impacts.
