Space Time Physics

Un día, Miguel estaba viendo Star Trek cuando, de pronto, se le ocurrió cómo revolucionar la teoría de la relatividad y viajar más rápido que la luz… La anécdota, que parece sacada de The Big BangTheory, es completamente real. La protagonizó un joven mexicano cuando estudiaba su doctorado en Cardiff. Este libro cuenta aquel momento, pero—más interesante aún—relata la ciencia que hay detrás de esa posibilidad, de aquellateoría de Einstein y de algunos de los postulados más espléndidos de la astrofísica.

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.

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.

Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High-energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole—heating it to millions of degrees as it is shredded at the event horizon.

Are you captivated by the mysteries of the universe and the minds that unravel them? Eager to understand how a single equation transformed our understanding of everything from atoms to galaxies? Wondering how the thoughts of one visionary could redefine the boundaries of space, time, and reality itself? Dive into the extraordinary life and legacy of Albert Einstein in A Brief History of Albert Einstein - Space, Time, and Quantum Theory: E=mc² and the Foundations of Modern Physics.

It has been a long time to reconcile quantum physics and general relativity. To date, no globally accepted theory has been proposed to explain all physical observations save for the theory herein presented. The current understanding of gravity is based on Albert Einstein's general theory of relativity, which incorporates his theory of special relativity and deeply modifies the understanding of concepts like time and space. Within GR, gravity has two possible interpretations: a field one and a geometric one. According to the latter, that has become the prevalent one, gravity is due to the ...

As a subject, it has perplexed and fascinated generations of scientists, historians and more, and continues to spark the most intriguing questions being asked in science today. Can time be stopped? Is time travel possible? Does time even exist? In these 10 bite-sized essays, Colin Stuart delves into these big questions and uncovers the most awe-inspiring and revealing things we should all know about time.

His face is instantly recognisable. His name is shorthand for genius. Today, he's a figurehead as much as a man, symbolic of things larger than himself: of scientific progress, of the human mind, even of the age. But who was Einstein really? The Nobel Prize-winning physicist who discovered relativity, black holes and E = mc2, dined with Charlie Chaplin in Hollywood and was the inspiration for element 99, Albert Einstein was also a high school dropout with an FBI file 1,400 pages long. In this audiobook, Samuel Graydon's writing brings history's most famous scientist back to life.

Here are five accessible essays by those who walk the fine line between science and science fiction, moving ever further out in discovering the patterns of nature, aimed at listeners who share their fascination with the deepest mysteries of the universe. Includes essays by Stephen Hawking, Timothy Ferris, Alan Lightman, and more.

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born.

In Newton’s view, all objects exert a force that attracts other objects. That universal law of gravitation worked pretty well for predicting the motion of planets as well as objects on Earth and it's still used, for example, when making the calculations for a rocket launch. But Newton's view of gravity didn't work for some things, like Mercury’s peculiar orbit around the sun. The orbits of planets shift over time, and Mercury’s orbit shifted faster than Newton predicted. Einstein’s idea was that gravity is not a force, but it is really an effect caused by the curvature of space and ...

This short book presents a brief and concise exploration of the Duality of Time postulate and its consequences on General Relativity and Quantum Mechanics. To make it easier for citing, this book is presented in the form of a scientific paper, which will also make it more accessible and easier to be read by researchers who are interested in the astounding conclusions rather than any exhausting introductions which are provided in the previous books for more general readability.

One of the biggest questions Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. But his famous theory on the Big Bang ran into a crisis when the equations predicted a multiverse - countless different universes, most of which were too bizarre to support life. Holed away in the physics department at Cambridge, Stephen Hawking and his collaborator Thomas Hertog worked for twenty years on a new theory of the cosmos.

What exactly constitutes an atom? How and why did the universe come into existence and how will it end? What subatomic particles go to make up the Standard Model? This essay serves as an entry point to nuclear physics and contains many useful references to other work on this and related topics. The essay also deals with other fascinating stuff.

Stephen Hawking's worldwide best seller, A Brief History of Time, has been a landmark volume in scientific writing. Its author's engaging voice is one reason, and the compelling subjects he addresses is another: the nature of space and time, the role of God in creation, and the history and future of the universe.

The universe should be fun, and you’re about to discover an audiobook that understands that, weaving humor and wit into every minute so that you not only understand what you’re listening to, but enjoy the whole process.

The first popular introduction to Hawking's work, this program discusses the mysterious world of black holes, singularities, and the "big bang"--the point at which our universe may have begun.

How does it feel to orbit the Earth 10 times faster than a speeding bullet? What's it like to eat, sleep and go to the toilet in space? And where to next - the moon, Mars or beyond? Ask an Astronaut is Tim's personal guide to life in space, based on his historic Principia mission and the thousands of questions he has been asked since his return to Earth.

At the two four-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015, they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected, and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a powerful new path to understand the workings of the universe.

The Superluminal Universe reveals, for the first time in English, the incredible insights of French quantum physicist Professor Regis Dutheil. Thanks to the development of particle accelerators, physicists are now able to propel particles (tachyons) at a speed close to that of light (300,000 km per second). At these extreme speeds, the laws that govern our universe no longer apply. Professor Dutheil's work has shown that the theory of relativity is not incompatible with that of tachyons, provided that we allow for the possibility of a double reality.
