I’m nerdy, I like space and I loved this book! The most recent data set was made by an experiment called the Cosmic Background Imager, which released a new set of data in May that is rather spectacular.

Guth found no solution. According to the preface, this book was written for the nonscientist.

The basic idea behind inflation is that a repulsive form of gravity caused the universe to expand. There are no discussion topics on this book yet. Without the question answered his inflation theory remains unproven. By answering the question inflationafy what drove the universe into expansion, the inflationary theory can also answer some questions about that expansion that would otherwise be very mysterious.

Maybe Alan Guth should read how the Dogon tribe in Africa every 60 years have a celebration called ‘ sigui’ during which the shamans put on mask and perform James Brown like dances based on a cosmic ceremony on the motion of the “Dog Star”,Sirius. Guth describes his key insight from and the developments following on from it.

Spontaneous symmetry breaking is set at various Higgs values along the vacuum ring, arbitrarily during cooling after Big Bang.

So I started looking around for a book that would give me the foundation I need, and I settled on this one, because even though it was written ove A friend asked me how credible the “multiverse” theories are that imagine our universe as just one of a potentially infinite number of eternally generating bubble-universes, and I realized that I lacked even the basic scientific background concerning the Big Bang or the laws of matter and energy to provide an informed answer or an intelligent guess.

By Guth had published a paper describing how his supercooled-universe scenario was not ideal, as the “triggering mechanism” to exit such a state would require “extreme fine tuning of parameters” and felt a more natural solution was required.

This ratio was expected to be very close to one, this is called flatness problem: JewittJane LuuMichael E. The next part in Guth’s path came when he heard a lecture by Steven Weinberg in early Coming of Age in the Milky Wayp.


More recently, Guth has expressed his belief that our universe is just one of many universes that came into existence among countless others as part of a multiverse. I would not be surprised if he were soon awarded a Nobel in Physics. There are many versions of inflation that are much closer to the kinds of theories that we were developing in the ’80s and ’90s, so saying that inflation is right is by no means the end of the story.

At the present time, we have to take the overall factor that multiplies the predicted intensity of these ripples from observation. Steinhardt used spinodal decomposition for phase transition without bubbles.

Alan Guth – Wikipedia

A concise and human background for those who desire understanding of basic cosmology. This is more anecdotal than a rigorous scientific review Published March 18th by Basic Books first published The cyclic theory could die when that problem finally gets solved definitively. Subject history Discovery of cosmic microwave background radiation History of the Big Bang theory Religious interpretations of the Big Bang theory Timeline of cosmological inflationart.

Its like getting a second opinion from a pediatrician about kidney disease or a brain tumor. The description of the physics involved is, for what it is, at least as good, but it is a very broad overview, and other books can provide detail that it does not. The diagrams are well-prepared and helpful. Skip to main content.

Guth defined an idea that attempts to answer the greatest question of all time: As a result of quantum tunnelingthe false vacuum would eventually decay into a low- energy true vacuum, and Guth found that the decay of the false vacuum at the beginning of the universe could produce some amazing results, including a rapid expansion at ever-increasing rates, which he called cosmic inflation. Apr 21, Daniel Woodworth rated it it was amazing Shelves: It has the same temperature in all directions with a remarkable accuracy.

Most GUTs predict the generation of magnetic monopoles during spontaneous universf breaking, but none had ever been detected – the monopole problem. Gth Unification Theories requiring that he think a lot about the physics of the ultra high temperatures of the early Universe.

This seemed very paradoxical because, when the radiation was released aboutyears after the Big Bang, the observable universe had a diameter of 90 million light-years. Critical chapter; needs re-read! But while this, and his often whimsical style, are pleasing, what really matters is that this book provides an overview, for those who need one like me of univere entire history of 20th century cosmology and particle physics, from Einstein’s theory of relativity to the discovery by Hubble that the inflaationary is expanding, to the confirmation of the Big Bang theory in the early s with the discovery of the cosmic background radiation, to the development of the standard model of particle physics inflationagy the s quarks, etc.


I found Guth’s writing to be superb.

Soup could be eternal. The Inflationary Universe An article within the collection: This is indeed the standard story, but I am shocked to see how many assumptions you need in order to make it work. The universe after inflation would have been very uniform even though the parts were not still in touch with each other.


With aln trade-off awareness gained, some brief summaries available online have a place to fit in. Doctors defer to other doctors who have more experience in a specialty. So far, he has written about 60 technical papers related to the effects of inflation and its interactions with particle physics. But they also said that they could offer more than that — there’s also dark matter.

The Inflationary Universe: The Quest for a New Theory of Cosmic Origins

Jun 08, Damon rated it it was amazing. Inflation does not depend sensitively on what you assume existed before inflation; everything there just gets washed away by the enormous expansion. In the alternative case, inflatioary the expansion dominated, the universe would be geometrically open. The conventional Big Bang theory without inflation really only worked if you fed into it initial conditions which were highly finely tuned to make it just right to produce a universe like the one we see.

Abstract The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: It’s very important to remember that inflation is really a class of theories. Guth has researched elementary particle theory and how particle theory is applicable to the early universe.

But it appears that Mr.
