the Universe Between Moments: A Human Guide to Time, Space, Matter, and Edge of Knowing

What is time?Why does the universe have a beginning? What happens inside a black hole? Why does the future feel different from the past? And how can a species living on one small planet hope to understand a cosmos billions of light-years across?The Universe Between Moments is an accessible journey through some of the deepest questions in modern science.Beginning with the scale and history of the cosmos, Abhishek Kumar explores the ideas that transformed our understanding of reality-from relativity and quantum mechanics to black holes, entropy, dark matter, dark energy, and the expanding universe.Along the way, the book asks questions that reach beyond equations.How did matter become stars, planets, and eventually life? Could life exist elsewhere? Is time fundamental, or something that emerges from deeper laws? What might have happened before the earliest moments we can observe? And where does our current understanding finally break down?Written for curious readers rather than specialists, The Universe Between Moments separates established science from speculation while explaining difficult ideas through intuition, examples, and thought experiments.Inside, you'll explore: - The birth and evolution of the universe - Einstein's strange picture of space and time - Quantum uncertainty and the microscopic world - Black holes and the limits of known physics - Entropy and the arrow of time - Dark matter and dark energy - Stars, galaxies, planets, and the search for life - The mysteries of consciousness and observation - Quantum gravity and competing ideas about deeper reality - Possible futures-and the eventual fate-of the cosmosThe universe has existed for billions of years.Yet for a brief moment, part of it has become capable of asking what it is.This book is about that moment.
