Cosmic Expansion by Eleanor Hawking

"Cosmic Expansion" explores the accelerating expansion of the universe, a groundbreaking discovery in cosmology. It examines evidence supporting this phenomenon, dark energy's role, and the implications for the universe's fate. One intriguing aspect discussed is how the expansion challenges our current understanding of physics, particularly the standard model of particle physics. The book also highlights observations from the Hubble Space Telescope, WMAP, and the Planck satellite, showcasing how data from these sources support the accelerating expansion.

The book progresses by first introducing fundamental cosmology concepts like the Big Bang theory and the cosmic microwave background. It then presents evidence for accelerated expansion through supernova observations and baryon acoustic oscillations. Finally, it delves into potential future scenarios like the Big Rip, Big Freeze, and Big Crunch.

"Cosmic Expansion" stands out by focusing specifically on the physics of cosmic expansion and dark energy, making it a valuable resource for students, researchers, and anyone interested in astrophysics.
