Introduction To | Cosmology

Cosmology shifts our perspective from the local to the infinite. It reveals a universe that is dynamic, evolving, and largely invisible. While we have mapped the history of the cosmos back to its earliest seconds, the nature of dark energy and the exact mechanism of the Big Bang remain the great frontiers of modern science.

The study of cosmology is our attempt to understand the universe as a single, physical entity. While early humans looked at the stars and created myths to explain the heavens, modern cosmology uses the rigorous tools of physics and mathematics to answer the "big questions": Where did we come from, how is the universe structured, and how will it end? 1. The Expanding Universe Introduction to Cosmology

The ultimate fate of the cosmos depends on the battle between gravity and dark energy. Current data suggests we live in a "flat" universe dominated by dark energy, leading to a scenario known as the In this future, galaxies will move so far apart they become invisible to one other, stars will run out of fuel, and the universe will eventually become a cold, dark, and empty void. Conclusion Cosmology shifts our perspective from the local to

An invisible form of matter that does not emit light but exerts gravitational pull, holding galaxies together. The study of cosmology is our attempt to

A repulsive force that appears to be accelerating the expansion of the universe, pushing galaxies apart at an increasing rate. 4. The Fate of the Universe
