@theory_of_relativity2: The expanding universe refers to the idea that the fabric of space itself is growing, causing galaxies to move farther apart from each other. This concept, supported by Edwin Hubble's discovery in 1929, revolutionized our understanding of cosmology. The expansion is often linked to the Big Bang theory, which suggests the universe began from a hot, dense state and has been expanding ever since. As galaxies move apart, light from them shifts to the red end of the spectrum, a phenomenon known as redshift, which provides evidence for the universe’s continual expansion. #ExpandingUniverse #BigBangTheory #Cosmology #Astrophysics #SpaceScience #HubbleLaw #Redshift #AstronomyFacts #LearnWithMe #UniverseMysteries
