Key ideas from Brian Cox

• "In 400 years from Kepler and Galileo, we've gone from essentially the same view of the natural world as ancient Egypt to the modern world because we worked out how to do science" - Brian Cox
• Emergence explains how complex phenomena like consciousness arise from simple underlying laws, though we can't predict them from studying individual components alone
• Dark matter is supported by multiple independent observations including cosmic microwave background sound waves, making it likely some kind of particle rather than modified gravity
• The standard model has three identical families of fundamental particles (quarks and leptons), but physicists don't know why nature chose exactly three generations
• "If you try to probe smaller than the Planck length by increasing photon energy, the energy density creates a black hole that grows larger, preventing you from seeing smaller" - Brian Cox on fundamental limits
• Information is never destroyed in physics - even burning an iPad theoretically preserves all data in the scattered photons and particles, though practically unrecoverable
• Quarks cannot be isolated because pulling them apart adds enough energy to create new quark pairs through hadronization, preventing single quark observation
• Inside a black hole's event horizon, you have roughly 24 hours before reaching the singularity for supermassive black holes like M87, where time itself ends
