Feynman erklärt: Das Universum ist voller Sterne – aber warum ist es schwarz? | Quantenphysik-Rätsel

Why is it dark at night, even though the universe is full of stars? (Olbers Paradox) We'll crack the Olbers Paradox Feynman-style: speed of light, age of the universe, Big Bang, redshift, tunneling effect, and cosmic microwave background radiation. Plot twist: The sky is shining—only invisibly. ⏱️ Chapters 0:00 Why is it dark at night? 0:56 Intro: Understanding like Feynman 1:31 The Forest Experiment 2:50 Why distant stars don't help 4:31 Olbers Paradox & the Dust Trap 6:25 Speed ​​of Light & Age of the Universe 8:31 Quantum Physics: Tunneling Effect in the Sun 10:50 Expansion & Redshift 13:31 Plot Twist: Cosmic Microwave Background Radiation 16:31 Will the sky get even darker? 17:20 Feynman Challenge & Outro 🔔 Subscribe:    / @verstehenwie.  . 💬 Explain it in one sentence – the best answer will be pinned! ⚠️ Disclaimer: For educational purposes only.
