Expanding Universe
Galaxies formed early in cosmic history, within a few hundred million years of the Big Bang. This shows that structure emerged quickly from an initially simple universe. Observations confirm that gravity wasted little time turning primordial gas into organized systems, even before features we now consider typical. Such as central supermassive black holes commonly found in galaxies.

Trivia: Did Einstein or Galileo discover the Relativity Principle?
Relativity
Galileo Galilei showed that constant motion is undetectable. That physics works the same on a smooth ship or solid ground. Isaac Newton made gravity universal. Centuries later, Albert Einstein extended Galileo’s insight. Einstein revealed that space and time are intertwined. Energy is matter, and gravity is the very fabric of spacetime itself.
