Physics Cosmology

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 ...

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.

The universe is full of matter and the attractive force of gravity pulls all matter together. The expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. It turns out that ...

The marvelous complexity of the universe emerges from several deep laws and a handful of fundamental constants that fix its shape, scale, and destiny. Where did these laws and these constants come from? And why are the laws so fruitful when written in the language of mathematics? Author Peter Atkins considers the minimum effort needed to equip the universe with its laws and its constants. He explores the origin of the conservation of energy, of electromagnetism, of classical and quantum mechanics, and of thermodynamics, showing how all these laws spring from deep symmetries.

A wise, very old, strongly clairvoyant lady leads us on a fictional journey through an imaginary land that symbolizes the levels of conscious of the mind of Homo sapiens. Perhaps there are many universes. Perhaps there is an unlimited number of virtual realities.

In Fantastic Numbers and Where to Find Them, leading theoretical physicist and YouTube star Antonio Padilla takes us on an irreverent cosmic tour of nine of the most extraordinary numbers in physics. These include Graham's number, which is so large that if you thought about it in the wrong way, your head would collapse into a singularity; TREE(3), whose finite value could never be reached before the universe reset itself; and 10^{-120}, which measures the desperately unlikely balance of energy the universe needs to exist....

The science behind the debate raging in modern physics over the disconcerting and uncomfortable realization that just maybe there is, as astronomer Fred Hoyle put it, some sort of "superintellect that has monkeyed with the physics". Written with the non-scientist in mind, this exploration of the big bang, Schroedinger's cat, the chaos of 9/11, the complexity of the mimic octopus and the blister beetle, and the strong anthropic principle is accessible to anyone bright enough to be interested.

The Cybernetic Theory of Mind series is a collection of books by evolutionary cyberneticist and philosopher Alex M. Vikoulov on the ultimate nature of reality, consciousness, the physics of time, quantum cosmology, computational physics, philosophy of mind, foundations of quantum physics, the technological singularity, transhumanism, posthumanism, the impending phase transition of humanity, the simulation hypothesis, economic theory, the extended Gaia theory, transcendental metaphysics and God. If you're eager to familiarize with probably the most advanced ontological framework to date or ...

Physicist Harry Cliff ventures out in search of the ultimate apple pie recipe, tracing the ingredients of our universe through the hearts of dying stars and back in time to a tiny fraction of a second after our universe began. Along the way, he confronts some really big questions: what is matter really made of? How does the stuff around us escape annihilation in the fearsome heat of the Big Bang? And will we ever be able to understand the very first moments of our universe?

When Stephen Hawking died, he was widely recognized as the world's best physicist, and even its smartest person. He was neither. In Hawking Hawking, science journalist Charles Seife explores how Stephen Hawking came to be thought of as humanity's greatest genius. Hawking spent his career grappling with deep questions in physics, but his renown didn't rest on his science. He was a master of self-promotion, hosting parties for time travelers, declaring victory over problems he had not solved, and wooing billionaires.

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.

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.

The Science and Philosophy of Information book series is adapted for general audience and based on the previously published grand volume titled “The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution” by digital philosopher Alex Vikoulov on the ultimate nature of reality, consciousness, the physics of time, philosophy of mind, digital physics, the technological Singularity, transhumanism, the impending phase transition of humanity, the simulation hypothesis, digital philosophy, foundations of quantum physics, extension to the original gaia hypothesis, economic theory, ...

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.

What is it that helps both scorpions and cyclists to survive? What do raw eggs and gyroscopes have in common? And why does it matter? In an age of string theory, fluid dynamics and biophysics, it can seem as if the science of our world is for only specialists and academics. Not so, insists Helen Czerski - and in this sparkling new audiobook she explores the patterns and connections that illustrate the grandest theories in the smallest everyday objects and experiences.

Everywhere light goes, It has found that darkness is already there. Darkness is the natural state of the universe. For a star to be born, it takes an astounding number of possibilities to become a reality. From this unlikely alignment, we now have trillions of stars! Thankfully stars would progress to give us light, life, and an observable universe. No one knows how many stars exist, but we will tour a handful of the most famous in our known universe. Sit back and enjoy the world of outer space that spreads before you. Each constellation and luminary has a story that you won’t want to miss!

Mind Openers 2.0 is the second installment in a two-part set. It takes a fresh look at relativity, cosmology, and quantum theory by imagining a “sandbox universe”, in which space and time are treated as tangible and visualizable phenomena. In addition to providing an intuitive feel for the physics, the model makes a number of acutely unexpected predictions. The author is a geophysicist (MSc, fellow of geoscientists, Canada) and educator, who specializes in translating scientific material for the non-expert.

Were ancient Greek philosophers right about reality being only an illusion? What was really the biggest blunder of Einstein's life? Is everything we've been taught about the universe incorrect? In The Unobservable Universe, visionary scientist and engineer Scott M. Tyson successfully unravels cosmology from the level of rocket science and brings it down to Earth, demystifying the universe in terms that laymen can comprehend and enjoy, splitting atoms but not hairs on this magical mystery tour of the outback of time and space.

Y si existiera una cuarta dimensión espacial que no pudiéramos percibir? ¿Y si el tiempo, que nos parece una realidad implacable, no fuera más que una ilusión de nuestra mente? ¿Y si nuestro universo fuera sólo uno de los muchos que integran un complejo multiverso inflacionario? Estas preguntas, que parecieran derivadas de un guion de ciencia ficción o propias de un temperamento esotérico, constituyen algunos de los planteamientos más rigurosos de la física moderna. Y son la fascinante materia de este libro.

According to some theoretical physicists, the universe exists by a long series of accidental and fortuitous events. When we examine the scientific evidence of our universe, we find that it began when nothing existed. Upon the commencement of our universe, precise events took place at specific moments of Planck Time, in exact balance with each other, to exact a specific outcome. When we build a house, the same process ensues. We have an idea. We draft a plan. We engineer the plan so that we will know ahead of time whether the house can be built by a specific procedure. We begin to build and ...
