That is not proof that the universe came from philosophical nothingness. In a debate about the question, physicist Lawrence Krauss said the universe’s observed properties are consistent with such an account, but added: “Does that prove it was the case? Absolutely not!”
What does “nothing” mean in physics?
The answer depends on what counts as nothing. An empty quantum vacuum is not absolute nonbeing: it is a physical state with structure, described by physical theory. A more ambitious cosmological proposal asks whether space and time could arise rather than already exist. That is different from saying that absolutely nothing—no space, time, matter, energy, quantum state, or laws—produced something.

This distinction is central to the Craig–Krauss debate. Krauss discusses a possibility in which there is no classical space or time before a universe appears, while acknowledging that physical laws remain part of the account. Philosopher William Lane Craig objects that a state described by laws is not nonbeing in the philosophical sense. Their disagreement is an argument about what the models mean, not a settled conclusion supplied by the debate transcript. Read the debate transcript.
What does the reported “proof” actually claim?
A 2014 Futurism article by Joshua Filmer described a theoretical proposal by Dongshan He and colleagues. It invoked the Wheeler–DeWitt equation and the uncertainty principle to describe an expanding bubble of true vacuum. The article’s headline calls this “proof,” but the account describes a mathematical proposal—not an established observational demonstration that the universe emerged from nothing.

A model can show that a proposed origin is mathematically possible under specified assumptions. That is not the same as observing the origin, establishing that the model describes what actually happened, or showing that its starting assumptions came from absolute nothingness. The proposal therefore supports a possibility claim, not a conclusive answer to the historical or philosophical question.
Does the Big Bang explain what came before?
Not necessarily. The question “What happened before the Big Bang?” assumes that “before” has meaning in this context. Krauss argues that time itself may arise out of the Big Bang, in which case there may be no earlier time to refer to. In the debate, he put it this way: “Time itself may arise out of the Big Bang. There may be no time before the Big Bang in which case the question ‘What happened before?’ is simply not a good question.” This is a participant’s argument, not proof that every account of the early universe excludes a prior state.

Rank #2
Even if a model describes the beginning of observable expansion or the emergence of classical space-time, it does not automatically explain why there is anything at all. The model may still assume a quantum state, physical laws, or a mathematical framework. Whether those assumptions answer the philosophical question depends on what one means by “nothing” and what kind of explanation one is seeking.
What can we conclude?
- Theoretical possibility: Some proposals describe a universe arising from a quantum state, or space-time emerging rather than existing classically beforehand.
- Empirical proof: The cited debate and 2014 news account do not establish that this is what actually happened. Krauss explicitly distinguishes consistency with observations from proof.
- Philosophical explanation: A physical model that starts with laws or a quantum state does not, by itself, settle why anything exists rather than nothing in the sense of absolute nonbeing.
For Krauss’s own account of cosmology and the origin question, Arizona State University discusses his book A Universe from Nothing: Why There Is Something Rather Than Nothing. It presents Krauss’s perspective; it should not be mistaken for independent proof of the claim. See Arizona State University’s book overview.
