🧠 Think energy is always conserved? Think again.
This episode will completely change your understanding of one of physics' most fundamental laws — the law of energy conservation.
I Misunderstood Energy Conservation for Years – Here's the Truth | Daily Dose | Ep. 10
🎥 In this video, we explore:
✅ Why energy conservation may not apply in an expanding universe
✅ How Noether’s Theorem links conservation laws to symmetries
✅ Real-world cosmological phenomena where energy isn’t conserved
✅ What this means for the Big Bang, Dark Energy, and the end of the universe
🎯 Key Points Covered in This Video
