A boundary-breaking astrophysicist reimagines the universe—and our place within it—in this audacious journey through the Nine Realms of the cosmos. The universe gave rise to everything: stars and cells, minds and memories, purpose and pain. But it doesn’t care about us. It follows its own...

Ao longo da história, encontramos grandes pensadores, cientistas e inventores que, num rompante criativo, desafiam nossos paradigmas e nos atiram sem piedade a uma nova realidade, que a princípio pode parecer desconfortável, incompreensível ou até questionável. Mas, afinal, de onde surgem as grandes ideias?

COMO O UNIVERSO SURGIU? QUAL SERÁ SEU DESTINO? O QUE HÁ NELE? Em O universo escuro, a astrofísica Larissa Santos convida o ouvinte a mergulhar nos maiores enigmas da cosmologia contemporânea: a matéria escura, a energia escura e os limites do conhecimento científico. Com linguagem acessível e, ao mesmo tempo, rigorosa, a autora percorre os fundamentos da física moderna e as descobertas que abalaram a forma como compreendemos o cosmos. Neste audiolivro, não há espaço para respostas fáceis.

The extraordinary true story of Lockheed Martin’s “Skunk Works”—the radical innovation hub that designed the greatest airplanes of the twentieth century—and the visionary who made it all possible "A kerosene-soaked masterclass in what extreme innovation looks, feels, and even smells...

"The Roswell Report: Case Closed" by James McAndrew is a historical account produced by the United States Air Force, written in the late 20th century. The book centers on the infamous Roswell Incident of 1947, which has fueled decades of speculation regarding extraterrestrial life and UFOs...

This book challenges the centuries-old pursuit of a final theory in physics by revealing why reality resists scale-independent description. Drawing on developments in effective field theory, renormalization, and the philosophy of science, it argues that physical laws are not universal absolutes but layered tools adapted to context. With clarity and precision, it explores the limits of unification, the power of pragmatic models, and the intellectual maturity required to live with structural incompleteness.

Why is the fine-structure constant approximately one over one hundred and thirty-seven? Why is the proton exactly 1836 times heavier than the electron? Why is gravity so absurdly weak compared to the other forces? For more than a century, physicists have measured the fundamental constants of nature with exquisite precision—yet no one can explain why they have the values they do. Three answers have been proposed. The constants are brute accidents with no deeper explanation. They will one day be derived from a final theory.

For half a century, cosmology has relied on two invisible ingredients to explain the universe: dark matter, a substance that has never been detected despite decades of experimental search, and dark energy, a repulsive force whose physical nature remains entirely unknown. Together, they are said to constitute ninety-five percent of the cosmos. The remaining five percent—ordinary atoms, light, everything we have ever touched or measured—is treated as a minor addendum to a universe made mostly of darkness. This textbook presents a different cosmology. It is not speculative.
