The Intrepid Jellyfish Dives Into a Black Hole: Explanations

Available on lulu.com

The Intrepid Jellyfish Dives Into a Black Hole: Explanations gives a lighthearted, accessible, yet thorough explanation of the science of black holes.

Imagine a universe with the same physical laws as ours but teeming with space jellyfish and other intergalactic creatures. An intrepid jellyfish sets out on an expedition to a black hole, traveling in a spaceworthy submarine. The submariner drops the jellyfish off and watches it dive down into the black hole. The jellyfish knows that once it gets past a certain point—the event horizon—it will be on a one-way trip.

As the jellyfish falls deep into the black hole, it sees the universe and its denizens—not to mention the submarine—become multiplied, multicolored, distorted, and generally weird. You’ll share its bizarre experiences: there’s a lot to see, and even more to wrap your mind around.

The copiously illustrated Intrepid Jellyfish books are grounded in Einstein’s theory of general relativity. This standalone book—the second and most detailed—shows not only what the jellyfish and the submariner see, but also why they see it. You don’t have to be a physicist or mathematician to enjoy this book: all it takes is the desire to understand the mysteries of the universe.
