We all are born in a place where every one of us has been sharing almost the same amount of spacetime curvature. But, It would be a misconception to think of the entire universe this way. We, humans, are just sharing a small common frame of reference, and there are innumerable frames of reference that are bizarrely different relative to ours. All About Spacetime is all about understanding the fabric of spacetime and its stranger versions and its influences on mass-energy, This book starts with the introduction of very fundamental topics like what is the fabric of spacetime to understand some of the different versions of it including singularity, primordial singularity, wormholes, spacetime cutoff, etc. The content of the book is oversimplified, making the content perceivable to even beginners. This book would be a boon for beginners as well as for the readers who have the basic concepts of astrophysics cleared. Virtually no maths has been used in the content and even if there is a little, the reader always has an option to skip the math part, thus maintaining the flow of reading with no loss in understanding the content as a whole. In most of the parts of this book, I have emphasized visualization of the concept rather than skipping it by using any technical word that many pretend to understand. Visualization of these concepts will just never fail to wonder anyone about the stranger version of reality, described in this book.
