I'm really enjoying how this book is coming together at the end. Right now the author is talking about Einsteins "biggest blunder" in which he did not take into account the universe is expanding. I like how the author explains that an expanding universe suggests the universe began with a big bang and then goes on to give three pieces of evidence that support the big bang theory.

I think it's great that the author uses two dimensional examples to show how gravity bends space time and how black holes are created in respect to event horizons. I can't conceive how the event horizon of a black hole exists in three dimensional space.

A part I find pretty confusing is world lines and how they fit into space time. Space time, unlike the observable universe, is the same for everyone. But world lines(the path of your travel shown on a graph of time and space) can seem different to two people. The author explains that this is possible because space actually bends and constrains the movement of objects.

I am recommending this book because the author uses "thought experiments" to demonstrate special relativity. It makes it easy for any reader to understand no matter there background knowledge in science.

I highly recommend this book to anyone who finds conceptual learning mind blowing. So far, my favorite concept is time dilation. The author does a great job explaining and gives great examples with small visuals. You definitely don't have to be a genius to understand the basics of relativity.

I chose to read this book because I've never learned about relativity in a science class. So far, the book has explored the nature of light and gravity, and why perspective matters.
