Early Universe
Early Universe refers to the period of time between the Big Bang and the formation of the first stars and galaxies. During this time, the Universe was filled with a hot, dense plasma of particles that were constantly colliding and interacting with each other. As the Universe expanded and cooled, the particles began to combine and form atoms, which allowed light to travel freely for the first time. This event, known as recombination, occurred about 380,000 years after the Big Bang and is responsible for the cosmic microwave background radiation that we observe today. The study of the Early Universe is important for understanding the fundamental laws of physics and the origin of the Universe.
