Our understanding of the universe is constantly evolving from "summary" of Astrophysics for People in a Hurry by Neil deGrasse Tyson
Our understanding of the universe is constantly evolving. What we think we know today may very well be proven wrong tomorrow. This is the nature of science - an iterative process of refinement, adjustment, and sometimes complete overhaul. As technology advances and new data becomes available, our perceptions of the cosmos are reshaped and redefined. The history of astrophysics is a testament to this ever-changing landscape of knowledge. Concepts that were once considered unassailable truths have been discarded in the face of new evidence. For example, the geocentric model of the universe, with Earth at the center, was replaced by the heliocentric model proposed by Copernicus. This shift revolutionized our understanding of the cosmos and paved the way for further discoveries. Even today, our understanding of fundamental aspects of the universe is in flux. Dark matter and dark energy, for instance, remain mysterious entities that challenge our current understanding of the cosmos. These enigmatic forces exert a gravitational inf...
