What Is Time According to Physics

You have heard that time slows down near a black hole and that the stars you see tonight might already be gone, and you nodded along without really getting it. Every explanation seemed to need a whiteboard you never had.

This audiobook answers the question through the sky itself, one idea per chapter, in a voice built for listening rather than reading. You learn why the night sky is a view into the past, why the clocks on GPS satellites have to be corrected every day to stay in step with yours, and what would happen to a wristwatch drifting toward a black hole. Each idea rests on a single comparison you can hold in your head, with no equations anywhere, and the narrator says plainly where physics still has no answer.

By the last chapter, the age of the universe feels like something that includes you. Press play tonight and look up with new eyes.
