I am reading our mathematical universe by max tegmark and he keeps mentioning some sort of seed fluctuations that eventually grew into the galaxies and the structure of the universe, but I don’t really understand any of it. What are they? Is he talking about the cosmic web?
In: Planetary Science
Imagine the early universe as a perfectly smooth soup. Seed fluctuations are like tiny grains of salt sprinkled unevenly into the soup.
These “grains” represent minuscule differences in density in the early universe. Over billions of years, gravity pulled denser areas together, causing them to grow and eventually form the galaxies, stars, and planets we see today. The cosmic web is the large-scale arrangement of these structures, like clumps in the soup.
