It suggests that the universe began as a hot, dense point and has been expanding ever since. This theory explains the observed redshift of distant force-motion-and-energy?dictionary=galaxies&did=855" onclick="getAsistant(this,event,855,'galaxies');return false;" style="color:#009000;">galaxies, the force-motion-and-energy?dictionary=cosmic+microwave+background+radiation&did=1230" onclick="getAsistant(this,event,1230,'cosmic microwave background radiation');return false;" style="color:#009000;">cosmic microwave background radiation, and the abundance of force-motion-and-energy?dictionary=light&did=966" onclick="getAsistant(this,event,966,'light');return false;" style="color:#009000;">light elements in the universe.

This means that the force-motion-and-energy?dictionary=galaxies&did=855" onclick="getAsistant(this,event,855,'galaxies');return false;" style="color:#009000;">galaxies are moving away from each other, and the force-motion-and-energy?dictionary=space&did=847" onclick="getAsistant(this,event,847,'space');return false;" style="color:#009000;">space between them is increasing. The expansion of the universe is a key concept in cosmology and is supported by various lines of evidence, such as the redshift of force-motion-and-energy?dictionary=galaxies&did=855" onclick="getAsistant(this,event,855,'galaxies');return false;" style="color:#009000;">galaxies and the force-motion-and-energy?dictionary=cosmic+microwave+background+radiation&did=1230" onclick="getAsistant(this,event,1230,'cosmic microwave background radiation');return false;" style="color:#009000;">cosmic microwave background radiation.

Cosmology also seeks to understand how large-scale structures, such as force-motion-and-energy?dictionary=galaxies&did=855" onclick="getAsistant(this,event,855,'galaxies');return false;" style="color:#009000;">galaxies, force-motion-and-energy?dictionary=galaxy&did=971" onclick="getAsistant(this,event,971,'galaxy');return false;" style="color:#009000;">galaxy clusters, and superclusters, formed in the universe. The distribution of these structures provides insights into the early universe and the processes that led to the formation of cosmic structures.
