Gravity's Influence on Cosmic Evolution: From the Big Bang to Galaxy Formation

Zhonglong Zhao*

Gravity, the most familiar and yet the most mystifying of nature's fundamental forces, has played a pivotal role in shaping the cosmos from the moment of the Big Bang to the intricate structures of galaxies we observe today. This omnipresent force has guided the cosmic evolution, acting as the architect of the universe's vast and majestic tapestry. In the saga of cosmic evolution, from the uniformity of the early universe to the complex galaxy systems, gravity has been the constant influence, sculpting the cosmos into its current form. This exploration delves into gravity's critical role in cosmic evolution, tracing its impact from the universe's fiery inception to the majestic galaxy formations that dominate the cosmic landscape.
