Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm- shifting view of how everything that exists came to be in the first place. A Universe from Nothing: Why There Is Something Rather than Nothing. Home · A Universe from Nothing: Why There Is Author: Lawrence M. Krauss. The question, "Why is there something rather than nothing? Lawrence M. Krauss is a renowned cosmologist and science popularizer, and is.

This is a brilliant and disarming book. As Lawrence Krauss lucidly explains, astronomers living two trillion years from now, will perhaps be pondering precisely the same question! Beautifully navigating through deep intellectual waters, Krauss presents the most recent ideas on the nature of our cosmos, and of our place within it. A fascinating read. The climax is a bold scientific answer to the great question of existence: Why is there something rather than nothing.

It is a question that philosophy and theology get themselves into muddle over, but that science can offer real answers to, as Krauss's lucid explanation shows. Here is the triumph of physics over metaphysics, reason and enquiry over obfuscation and myth, made plain for all to see: Krauss gives us a treat as well as an education in fascinating style.

What was there before it? What will the future bring? And finally, why is there something rather than nothing?

Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.

My fear that a theoretical physics book would induce something between a deep sleep and a coma before I finished the first page of equations, proved happily unfounded.

Krauss has taken enormous pains to explain the story in non-mathematical language, which could not have been easy or comfortable for him as a scientist with a reputation to protect.

He did an excellent job, and I am a grateful reader. My only reservation is that, having explained to us so well how quantum fluctuations can lead to something from nothing, he does not tackle the next turtle down, namely, what might have caused quantum fluctuations themselves, and the phenomenon of spacetime inflation, to exist?

A Universe from Someone: A critique of Lawrence Krauss

He invokes the bubbling oatmeal or turtle soup? I gather that the answers are yet to be discovered, but I would have appreciated him lifting this turtle too and peeking underneath, if only via speculation. Robert J. Nothing should not be thought to be a vacuum or a void which is dimensional and orientable — where you can have more or less space ; and it is certainly not a physical law.

Inasmuch as the laws of physics have real physical effects, they must be considered to be something physical. Therefore if at one time nothing was in existence, it would have been impossible for anything to have begun to exist; and thus now nothing would be in existence — which is absurd.

Where do the rules come from?

What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

It strikes me as genuinely incomprehensible that anything — laws, energy, etc. The fundamental physical laws that Krauss is talking about in A Universe From Nothing — the laws of relativistic quantum field theories — are no exception to this.

The… elementary physical stuff of the world, according to the standard presentations of relativistic quantum field theories, consists unsurprisingly of relativistic quantum fields. And the fundamental laws of this theory… have nothing whatsoever to say on the subject of where those fields came from, or of why the world should have consisted of the particular kinds of fields it does, or of why it should have consisted of fields at all, or of why there should have been a world in the first place.

Case closed.


End of story… Krauss seems to be thinking that these vacuum states amount to the relativistic-quantum-field-theoretical version of there not being any physical stuff at all.

And he has an argument — or thinks he does — that the laws of relativistic quantum field theories entail that vacuum states are unstable. And that, in a nutshell, is the account he proposes of why there should be something rather than nothing.

Relativistic-quantum-field-theoretical vacuum states — no less than giraffes or refrigerators or solar systems — are particular arrangements of elementary physical stuff.

And the fact that particles can pop in and out of existence, over time, as those fields rearrange themselves, is not a whit more mysterious than the fact that fists can pop in and out of existence, over time, as my fingers rearrange themselves.

And none of these poppings… amount to anything even remotely in the neighborhood of a creation from nothing.All rights reserved.

Recall that the empty space within protons is teeming with virtual particles that pop in and out of existence out of nothing. Space from Nothing So, we have established that, according to our best science as counter-intuitive as it sounds , an infinitesimal amount of energy could pop out of empty space to generate our current universe.

Quantum mechanics is a theory that developed between and as a way to explain the behaviour of elementary particles, such as electrons, which move in ways that are far different than everyday objects such as baseballs and bubble gum p. So we cannot be entirely sure, based on this method alone, of the mass of matter in the universe, and hence of its shape.
