P1: A belief: our galaxy is merely one among countless other galaxies -> distant galaxies are uniformly receding -> fundamental property of the universe: its expansion. Spacetime is not static but stretches, carrying galaxies with it.
Background information on the expansion of the universe
P2: Investigation: galaxy: distinct motion -> hinting large-scale mass density fluctuations. These movements help understand whether the universe continues to expand or recollapse due to gravity?
Raising a question on the universe expansion.
P3: A study by Edwin Hubble and Slipher solidifies the significance of galactic movement mentioned in P2, implied that galaxies are moving away from us. Static universe will soon be overshadow by the acceptance of uniformly expanding cosmos.
A study confirming the expansion of the universe
P4: By 1930, the expanding universe became accepting concept, encapsulated by the Hubble Law. By 1970, Hubble Law further implication was embraced – the universe’s expansion originated from the big bang 15bi years ago
