Where Does Energy Come From If It Cant Be Created? [VhArLPWaLRt]
Where does the energy inside your body come from, and can anything truly create energy from nothing? In this episode of The Sleeping Physicist, we follow the energy that moves your hand backward through food, sunlight, nuclear fusion, primordial hydrogen, and the earliest moments of the universe. Learn why energy can transform but never simply disappear, how the Sun converts mass into light, and why the hydrogen powering every star was formed during the first few minutes after the Big Bang. We also explore why energy is not a physical substance, how gravity may balance the universe’s positive energy, how vacuum energy relates to cosmic inflation, and why the deeper mystery may be the universe’s extraordinarily ordered beginning.
