In this book summary, you can expect to dive into a sea of intriguing hypothetical questions that lead us to the exciting world of science. Created for individuals in the age range of 20-40 years, Munroe sheds light on captivating questions, such as Australia’s potential to control the galaxy, constructing Rome in a day, surviving a trip to the depths of the Mariana trench, and much more! Prepare to expand your understanding of scientific concepts, all while remaining engaged in these eclectic hypothetical situations.

Jupiter’s Explosive Secret

Jupiter’s hot and compressed interior, with super-strong gravitational forces, would cause a massive explosion if it were shrunk to the size of a house. Although it has the same density as water, Jupiter’s original form was a big diffuse cloud of gas that collapsed in on itself due to gravity, making it tens of thousands of degrees hot. Despite the explosion, the good news is that it would be contained, and Jupiter would return to its original state as diffuse gas clouds.

Australia: The Galactic Controller

In a hypothetical scenario, if every country’s territory were extended infinitely upward, Australia would be the controller of the galaxy due to its location in the Southern Hemisphere. This is because the Southern Hemisphere is tilted advantageously towards the center of the Milky Way, where the supermassive black hole – the galaxy’s core – is located. As the Earth rotates every 24 hours, galactic territory would change hands from country to country. When the galaxy’s core is centered in Australian airspace, it would lay claim to more galactic territory than any other country. However, the Northern Hemisphere has its own advantages. It is tilted towards the outer galactic disk, which contains millions of planetary systems, such as the star 47 Ursae Majoris known to have three orbiting planets. During 12 minutes each day, technically any crimes committed on those planets would fall under the legal jurisdiction of the state of New Jersey. The book summary explores this interesting scenario with wit and clarity, providing a fascinating glimpse into the hypothetical world of space governance.

Could Rome be Built in a Day?

The article explores the possibility of building Rome in a day. Civil engineer, Daniel M. Chan, estimates that with a real estate value of $150 billion and construction costs of 60% of that value, it would take between 10 and 15 years to build Rome. However, if eight billion people worked on the project, it could be completed in little more than 15 minutes. Considering the artistic and architectural masterpieces, like the ceiling of the Sistine Chapel, the estimated time to construct all of Rome working at Michelangelo’s pace is 20 billion hours. Thus, eight billion workers could do it in about 2 and a half hours.

Deep Sea Adventure

Discover the wonders and dangers of the Mariana Trench in this breathtaking guide on submerging to the earth’s lowest point.

Welcome to the depths of the Mariana Trench, the world’s least-visited site with a plethora of mysteries waiting to be uncovered. But, before plunging into adventure, make sure to pack appropriately. Though the temperature at the bottom is slightly above freezing, you’ll still be cold without a nice thick sweater and a torch with long-life batteries.

Descending in a totally indestructible glass tube, three times deeper than the world’s deepest mines, you’ll find yourself exploring one of the most fascinating places on our planet. Yet, despite its allure, there are serious risks to contend with. Twice a year, if you’re lucky enough, you’ll see the sun pass directly above the mouth of your tube, but after that, it’s six months of total darkness.

If you don’t want to spend six months in the dark with frigid temperatures, knock a hole in the side of your glass tube to let in water, which will carry you up above sea level. But be warned, a supercharged jet of seawater will charge through the hole. Allowing water in slowly through a tap at the bottom of the tube is the only safe way to ascend. Once the tube has filled up with a kilometer or two of seawater, open it fully to rush more seawater in, and with a giant plunger, you’ll be back above sea level in no time, traveling at 500 miles per hour on a giant fountain of icy water.

Prepare yourself for an unforgettable experience as you embark on one of the most extreme adventures of a lifetime. Grab your sweater, torch, tap, and giant plunger. You’re all set for an exciting deep-sea adventure.
