NĂNG LƯỢNG ÂM: LÀM SAO CÓ THỂ ÍT HƠN CẢ “KHÔNG CÓ GÌ”?

Tonight, let's leave the hustle and bustle of the world behind, lie down comfortably, and join us on a journey into what seems like the most empty space in the universe. There, we'll begin with a very simple question: If 0 is the absence of energy, then what is -1 joule? Everything around us seems to need energy to exist and function. Phones need electricity, the body needs food, stars need fuel to shine. When energy is depleted, all activity must cease. Yet physics has a concept that sounds almost illogical: negative energy. How can something have energy lower than 0? If we remove everything from a region of space and only a vacuum remains, what else could we possibly take in? And is what humans call "nothing" truly empty? In tonight's cosmic story, we'll slowly journey from an imaginary machine with an energy level of -1 joule, into the world of quantum vacuum and the Casimir effect, then leave Earth to explore the strangest ideas of modern physics: wormholes, the bending of spacetime, and warp ships capable of traversing vast distances between stars. There's no need to memorize complex concepts. Think of it as a slow journey through the strange questions of the universe, letting the narrative and imagery of space take you away from your present room, past the stars, and into a deep night. You can listen to explore, to relax before sleep, or simply close your eyes and let the story continue. And who knows, before drifting off to sleep, you might still have one question lingering in your mind: If even “nothing” isn’t truly nothing… then what does the dark space between the stars really contain? 🌌 Listen to stories about the universe at night – strange scientific questions, journeys through space, and stories to help you relax, unwind, and gently drift off to sleep. #ListenToStoriesOfTheUniverse #NightUniverse #NightSpace #NumericalEnergy #QuantumPhysics #MysteriesOfTheUniverse #Science #GoodSleep
