Beschreibung The Music of the Big Bang: The Cosmic Microwave Background and the New Cosmology (Astronomers' Universe) (English Edition)

Ever since its infancy, humankind has been seeking answers to some very basic and profound questions. Did the Universe begin? If it did, how old is it, and where did it come from? What is its shape? What is it made of? Fascinating myths and brilliant in- itions attempting to solve such enigmas can be found all through the history of human thought. Every culture has its own legends, itsownworldcreationtales,itsphilosophicalspeculations,itsre- gious beliefs. Modern science, however, cannot content itself with fanciful explanations, no matter how suggestive they are. No- days, our theories about the Universe, built upon rational ded- tion, have to survive the hard test of experiment and observation. Cosmology, the science which studies the origin and evo- tion of the Universe, had to overcome enormous dif?culties before it could achieve the same level of dignity as other physical dis- plines. At ?rst, it had no serious physical model and mathematical tools that could be used to address the complexity of the problems it had to face. Then, it suffered from a chronic lack of experim- tal data, which made it almost impossible to test the theoretical speculations. Given this situation, answering rigorously the many questions on the nature of the Universe seemed nothing more than a delusion. Today, however, things have changed. We live in the golden age of cosmology: an exciting moment, when, for the ?rst time, we are able to scienti?cally understand our Universe.

Cosmic Microwave Background: Remnant of the Big Bang / Space ~ The cosmic microwave background (CMB) is thought to be leftover radiation from the Big Bang, or the time when the universe began. As the theory goes, when the universe was born it underwent a .

cosmic microwave background (CMB) / History & Formation ~ Cosmic microwave background (CMB), electromagnetic radiation filling the universe that is a residual effect of the big bang 13.8 billion years ago. Because the expanding universe has cooled since this primordial explosion, the background radiation is in the microwave region of the electromagnetic spectrum.

Cosmic Microwave Background: Big Bang Relic Explained ~ The Cosmic Microwave Background radiation tells us the age and composition of the universe. See what the CMB means for our understanding of the universe in this SPACE infographic.

What is the Steady State Hypothesis? - Universe Today ~ Another major argument against the Steady State Hypothesis was the discovery of the Cosmic Microwave Background (CMB) in 1964, which the Big Bang model predicted.

Lambda-CDM model - Wikipedia ~ The discovery of the cosmic microwave background (CMB) in 1964 confirmed a key prediction of the Big Bang cosmology. From that point on, it was generally accepted that the universe started in a hot, dense state and has been expanding over time. The rate of expansion depends on the types of matter and energy present in the universe, and in particular, whether the total density is above or below .

History of the Big Bang theory - Wikipedia ~ Huge advances in Big Bang cosmology were made in the 1990s and the early 21st century, . ESA's Planck spacecraft released even more detailed images of the cosmic microwave background, showing consistency with the Lambda-CDM model to still higher precision. Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding what .

Alexander Friedmann - Wikipedia ~ Alexander Alexandrovich Friedmann (also spelled Friedman or Fridman / ˈ f r iː d m ə n /; Russian: Алекса́ндр Алекса́ндрович Фри́дман) (June 16 [O.S. 4], 1888 – September 16, 1925) was a Russian and Soviet physicist and mathematician.He is best known for his pioneering theory that the universe was expanding, governed by a set of equations he developed now .

The Life of the Cosmos / Universe / General Relativity ~ the Big Bang, and the question of why the universe is hospitable to life. These are all problems we have so far failed to solve, in spite of having made partial progress on some of them. In my view, part of the reason for this is that we have not paid enough attention to the ways in which a theory that could be sensibly applied to the whole universe must differ from our present theories.

Big Bang Theory - The expanding Universe - AQA - GCSE ~ Learn about and revise red-shift, the expanding Universe, the Big Bang theory and the future of the universe with GCSE Bitesize Physics.

What Is Cosmology? Definition & History / Space ~ Cosmology by definition is the branch of astronomy involving the origin and evolution of the universe, from the Big Bang to the future of the cosmos.

What Is the Big Bang Theory? / Space ~ The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it talks about the universe as we know it starting with a small singularity, then inflating over the .

How Two Pigeons Helped Scientists Confirm the Big Bang ~ How Two Pigeons Helped Scientists Confirm the Big Bang Theory For decades, astronomers had debated how the universe began. Then, in 1964, they had their “Eureka!” moment

Our Expanding Universe: Age, History & Other Facts / Space ~ The universe was born with the Big Bang as an unimaginably hot, dense point. Space offers an overview of the universe and its history.

Big Bang: The Origin of the Universe: : Singh ~ The final nail in the coffin for the Steady State argument was the accidental discovery of cosmic microwave background radiation by Penzias and Wilson. Big Bang theorists had predicted the presence of this radiation, which dates back to about 300,000 years after the initiation of the universe, and they had been proved right. In the 1990s .

Space Ripples Reveal Big Bang’s Smoking Gun - The New York ~ Astronomers looking back 13.8 billion years found ripples in the fabric of space-time that support the theory of a universe being wrenched violently apart around its inception.

Astronomy - Copernicus / Britannica ~ Astronomy - Astronomy - Copernicus: Polish astronomer Nicolaus Copernicus announced the motion of Earth in De revolutionibus orbium coelestium libri VI (“Six Books Concerning the Revolutions of the Heavenly Orbs,” 1543). (An early sketch of his heliocentric theory, the Commentariolus, had circulated in manuscript in the small astronomical community of central Europe from about 1510, but it .

Big Bang: The Most Important Scientific Discovery of All ~ In the 1940s, Fred Hoyle, along with others, proposed an alternative to the Big Bang theory by suggesting a Steady State model in which the universe was expanding but where new matter was continually being created in the gaps between the old galaxies. The discrepancies in the age of the earth and the universe were less of a problem for this theory but it still had its own difficulties. It .

The Big Bang Theory: How the Universe Began / Live Science ~ The Big Bang theory describes how the universe began based on what cosmologists know about the sliver of existence visible today.
