Comments On: A Universe From Nothing

TL;DR

This paper critically examines claims in Krauss's book suggesting the universe can originate from nothing, arguing that modern physics does not fully support these assertions.

Contribution

It provides a critical analysis of popular claims about the universe's origin from nothing, highlighting gaps in their support from current physical theories.

Findings

Many claims are not supported by modern general relativity.

Quantum field theory in curved spacetime does not fully substantiate the claims.

The paper clarifies misconceptions about the universe's origins.

Abstract

We study some claims in Krauss' recent book, \emph{A Universe from Nothing: Why there is something rather than nothing}, that are employed to show that a universe can come from "nothing". In this brief paper, we show that many of the claims are not supported in full by modern general relativity theory or quantum field theory in curved spacetime.
