Time Cosmology

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

In this special thematic anthology, we traverse the solar system, the galaxies and the multiverse, voyaging across space to explore 25 celestial objects and phenomena. Included are programmes on the universe, the sun, the moon, the stars and the planets - among them our near neighbours, Venus and Mars. Also featured are discussions on comets, asteroids and black holes, as well as eclipses, exoplanets and the mysterious, invisible substance known as 'dark matter'.

"The Beginner's Guide to Parallel Realities" transforms mind-bending concepts into accessible insights that will forever change how you view reality. Using clear examples and engaging thought experiments, this guide breaks down complex theories about the multiverse, time travel, and alternate dimensions into digestible pieces that anyone can understand.

كان كتاب ستيفن هوكنج "موجز تاريخ الزمن" الذي صدر في عام 1988م والذي حقق أفضل المبيعات، علامة مميزة في الكتابة العلمية. ويرجع السبب في ذلك إلى صوت المؤلف الواعد والموضوعات الملحة التي تناولها: طبيعة المكان والزمان. ودور الرب في الخلق، وتاريخ ومستقبل العالم. ومنذ أن نشر الكتاب دأب القراء مراراً على مخاطبة الأستاذ هوكنج وإخباره بالصعوبات التي يلقونها في فهم الموضوعات الأكثر أهمية في الكتاب.

In 2000, Martin Bojowald, then a 27-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity - a cunning combination of Einstein’s theory of gravity with quantum mechanics - to create a simple model of the Universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do - illuminate the very birth of the Universe.

In this vibrant, eye-opening tour of milestones in the history of our universe, Chris Impey guides us through space and time, leading us from the familiar sights of the night sky to the dazzlingly strange aftermath of the Big Bang. What if we could look into space and see not only our place in the universe but also how we came to be here? As it happens, we can. Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past.

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.

Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones - from the tiniest particles to the nature of space-time itself - black holes might be the key to a deeper understanding of the cosmos.

Space is the biggest, oldest, hottest, coldest, strangest thing a human can study. It's no surprise then, that the weirdest facts in science (not to mention the weirdest scientists themselves) are found in astrophysics and cosmology. If you're looking for instructions on how to set up your grandad's telescope this book probably isn't for you. In Astronomical, Tim James takes us on a tour of the known (and unknown) Universe, focusing on the most-mind boggling stuff we've come across, as well as unpacking the latest theories about what's really going on out there.

This is an indispensable guide to physics that offers readers an overview of the most popular physics topics written in an accessible, irreverent, and engaging manner while still maintaining a tone of wry skepticism. Even the novice will be able to follow along, as the topics are addressed using plain English and (almost) no equations. Veterans of popular physics will also find their nagging questions addressed, like whether the universe can expand faster than light.

Do we really understand what gravity is? Taouil continues where Einstein left off, expanding on the theory of general relativity in a ground-breaking new concept about gravity and what it really is. His ideas are profound, and the implications can change the world of physics. The audiobook is easy to hear, and gives a step-by-step historical background to the science behind his observations that is both powerful and fascinating.
