Planet Earth is part of the cosmic landscape, sharing existence with billions of planets and solar systems. Our solar system resides in the Laniakea supercluster, which includes over 100,000 galaxies. These superclusters are seen as immense structures, yet they are largely illusory due to the influence of dark energy. The Universe originated approximately 13.8 billion years ago from the Big Bang, characterized by slight irregularities that fostered the competition between the Universe's expansion and gravitational forces, which shaped cosmic structures over time.
Planet Earth is unremarkable in the vast cosmic scale, orbiting a star within a solar system, itself part of numerous galaxies and superclusters.
Superclusters like Laniakea are vast structures, containing over 100,000 galaxies, but are merely apparent due to the influence of dark energy.
The Universe began 13.8 billion years ago with the Big Bang, marked by tiny imperfections that ultimately led to the formation of cosmic structures.
The expansion of the Universe and gravitation continually compete, influencing how matter and energy clump together across cosmic distances.
