A Light Year Is So Big Your Brain Can't Process It

Professor Jim Al-Khalili explores the extraordinary 600-million-year evolution of the human brain. From primitive sea creatures and the first neurons to the rise of mammals and the emergence of imagination, he uncovers the scientific breakthroughs that transformed a simple nervous system into the most complex organ in the known universe.

Thailand’s New Year celebrations bring huge crowds to Pattaya’s Walking Street and Koh Phangan’s Full Moon Party. As tourist police patrol through the night, a dispute at a nightclub turns into a brawl, partygoers lose their belongings, and one reveller’s attempt at fire skipping ends painfully.

Consciousness, the thought realm and the hero's journey — Spirit Science asks what your thoughts actually do once they leave your mind. We have mapped the body and the brain, but never the soul. This is the missing third: measurable thoughts, Emoto's water crystals, the monomyth, and our ruined soil. 📑 CHAPTERS 👉 KEY MOMENTS 👉 1:12 "We have scientifically mapped the mind and the body." 👉 5:39 "Emotions are much more powerful than thoughts. Emotions pull on you." 👉 6:58 "it's through the feeling of being vulnerable that you become vulnerable in the physical" 👉 8:09 "you can literally change everything in your life by willing it so" 👉 9:04 "If thoughts can do that to water, just imagine what thoughts can do to us." 👉 11:30 "It's a style as old as time and no one knows quite where it came from." 👉 22:34 "The best heroes have character, not gender." 👉 25:53 "How can anyone recommend a proper way of eating when 90 plus percent of the food that's available is trash?" 🌀 Welcome to Spirit Science

A devastating fall, a high-speed motorcycle crash, and a horrific head-on collision leave trauma teams battling to save multiple lives. As emergency doctors race against the clock, they face catastrophic brain injuries, internal bleeding, shattered bones, and impossible decisions where every second could mean the difference between life and death.

Can science really help us become fitter, younger, smarter and maybe even more perfect? In this episode of Myth or Science, Dr Jennifer Gardy puts some of the biggest health and human-performance claims to the test. Can exercise reverse aging? Is a few minutes of high-intensity training really as good as a long workout? Can you be fat and fit? Is willpower something you can train like a muscle? And could coffee, cooked food, music, or even sleep change the way our bodies and brains work? From intense lab tests and skin biopsies to MRI scans, DNA analysis, brain challenges, and music therapy after stroke, Jenn dives into the science behind the myths we hear every day. Along the way, she discovers that some “too good to be true” claims are surprisingly real, while others need a little more nuance. ------- Chapters ▷ 00:00 - Intro: Can Science Make Us Better? ▷ 01:27 - Can Exercise Reverse Aging? ▷ 03:47 - The Mice Experiment: Exercise vs. Aging ▷ 05:35 - Skin Biopsy Results: From 70 to 40? ▷ 07:44
