What is the Universe—and where do we fit inside it? From tiny particles to enormous galaxies, the Universe contains everything we know about space, time, matter, and energy. In this educational video, we'll zoom out from Earth and explore our cosmic home. 🌍 Our Cosmic Address Earth → Solar System → Milky Way → Local Group → Cosmic Structures → Observable Universe You'll discover just how incredibly small our planet is compared with the enormous scale of the cosmos. 🌟 In This Video, You'll Learn: What the Universe is What space and time mean What matter and energy are What stars are What planets are What galaxies are Where the Solar System is located What the Milky Way is What black holes are What dark matter means What dark energy means What the observable Universe is How scientists estimate the Universe's age What the Big Bang theory explains How stars and galaxies formed Why the Universe is still expanding 💥 The Big Bang The Big Bang theory describes the Universe's evolution from an extremely hot, dense early state. As the Universe expanded and cooled, particles formed, followed by atoms, stars, galaxies, and eventually planets. Today, the Universe is approximately 13.8 billion years old and continues to expand. 🔭 How Big Is the Universe? The observable Universe is roughly 93 billion light-years across. But the entire Universe could be much larger—and scientists don't currently know whether it is finite or infinite.
