Origin: This vast expanse is believed to have originated from the Big Bang nearly 14 billion years ago and has been expanding ever since Key concepts of the Big Bang theory: Initial state: The universe originated from an infinitesimally small, hot, and dense point, often called a singularity. Rapid expansion: In the first fraction of a second, the universe underwent an exponential expansion known as cosmic inflation. This stretched the universe. As the universe expanded, it cooled. Subatomic particles like quarks and gluons formed, which then combined to create protons and neutrons. Further cooling led to the formation of the first light elements, primarily hydrogen and helium, during a process called Big Bang nucleosynthesis. About 380,000 years after the Big Bang, the universe cooled enough for electrons to combine with nuclei to form the first neutral atoms. This event, known as recombination. Made the universe transparent for the first time, allowing light to travel freely. Gravity acted on the slightly denser regions of matter, causing them to pull in more material over billions of years. This process led to the formation of gas clouds, stars, and galaxies. Recent observations indicate that the expansion of the universe is accelerating. This is attributed to a mysterious force called "dark energy". Key Components of Universe: Space and Time: These are fundamental components of the universe, forming what is known as space-time. Matter: This includes everything that has mass and takes up space, such as planets, stars, galaxies, gases, and dust. Energy: The universe also contains various forms of energy, including light and other forms of radiation. Physical Laws: The universe is governed by physical laws that dictate how matter, energy, and space-time interact.
