NASA | Beyond Einstein: Part I

The video explores Albert Einstein's transformative contributions to physics, including his 1905 papers that reshaped our understanding of atoms, light, and relativity. It discusses the implications of his theories on gravity and space-time, leading to the concept of an expanding universe. The video also highlights modern challenges in cosmology, such as dark energy, and NASA's efforts to explore these mysteries through advanced missions. It emphasizes the ongoing quest to understand the universe's fundamental laws and the role of dark energy in its accelerated expansion.
