Physics Cosmology

O tempo não é um conceito abstrato. É uma substância material que ocupa todo o universo e se deforma, vibra, oscila. De Newton a Einstein, de Planck ao relógio cósmico, foi protagonista de metamorfoses vertiginosas, fascinantes e monstruosas. O tempo flui? Ou está parado? E como é medido? Como a gravidade o retarda? E como os buracos negros conseguem pará-lo? Sempre vivemos no tempo, que, no entanto, não é eterno.

Cosa succederebbe se la Terra orbitasse attorno a un buco nero? E se dalla sua superficie sparissero tutti gli oceani? E se venisse colpita da una supertempesta solare? E il Sole, appunto: se un giorno levassimo il naso all'insù senza più vederlo? Se qualcuno volesse improvvidamente tentare di spegnerlo con una gigantesca secchiata d'acqua? (Spoiler: sarebbe una pessima idea.) E la Luna! Cosa accadrebbe se una notte in cielo ne spuntassero due? Raddoppierebbe la poesia o ci ritroveremmo non esattamente nelle condizioni ideali per apprezzare la cosa?

Vorwärts in die Vergangenheit. Weiße Löcher sind das Gegenteil von Schwarzen Löchern – sie sind vermutlich ihre Abkömmlinge. Die einen ziehen alle Materie unwiderstehlich in sich hinein, die anderen geben ihre Information wieder frei. Sie sind ein weiteres großes Rätsel der Kosmologie, und noch gibt es keinen Beweis ihrer Existenz. Einsteins Gleichungen lassen sie aber vermuten, und mit Carlo Rovellis Quantentheorie sind Weiße Löcher theoretisch darstellbar.

Black holes are the most extraordinary phenomenon in the universe, but they are a riddle that confounds our intuitions. Anything that enters them can never escape and yet they contain nothing at all. They are bigger on the inside than the outside suggests. They are dark on the outside but not on the inside. They invert time into space and space into time.

The "universe" refers to all "observable things", ranging in size from the entire cosmos to elementary particles. A guide for an enjoyable visit to the universe, this small tome on fundamental physics, cosmology, Higgs bosons, time travel, and all that is unlike any other analogous book. Its scientific statements are correct or, at least, they coincide with the opinions held by the vast majority of experts. It establishes clear distinctions between things we know for sure and things that we know that we do not know, or we do not understand.

The European Space Agency released a map of the afterglow of the big bang map, which contains anomalies that challenge our understanding of the universe. This is the first book to address what will be an epoch-defining scientific paradigm shift. Will we ever know what happened before the big bang? What's at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?

Stargazing has shaped the entire course of human civilization. The rhythm of our ancestors' lives revolved around the stars, from cycles of agriculture to patterns of birth. How radically different would humanity be if our ancestors had looked up to the night sky and seen...nothing? In lyrical yet evidence-grounded meditations, Trotta imagines a world without stars, a dramatic alternate history in which we wouldn't understand gravity, where couldn't navigate or have much sense of time, and where our sense of the profound - of art and of the divine - was altered beyond recognition.

Forty-four science articles using the Rational Scientific Method of Inquiry. These subjects are covered in the book Curious Chain of Events, and this is the first in a series of Rational Science books.

Have you ever found yourself wondering what we might have in common with stars or why the moon never leaves us? Thinking about the precise dancing of planets, the passing of time or the nature of natural things? Our world is full of unshakable mystery, and although we live in a civilisation more complicated than ever, there is beauty and reassurance to be found in knowing how and why.
