Detailed explanation-1: -The universe is just homogeneous (the same everywhere), and it’s large enough that light hasn’t had enough time to cross it since the CMB was emitted. The CMB we see is from the same distance in every direction because it’s all been traveling for the same amount of time.
Detailed explanation-2: -No, the highly diverse distribution of cosmic matter that we see in the Universe at present – stars, galaxies, galaxy clusters – has not always been in place.
Detailed explanation-3: -The cosmic microwave background (or CMB) fills the entire Universe and is leftover radiation from the Big Bang. When the Universe was born, nearly 14 billion years ago, it was filled with hot plasma of particles (mostly protons, neutrons, and electrons) and photons (light).
