## Is quantum foam proven?

There is no such thing as empty space; there is only ‘quantum foam,’ everywhere. Such is space-time for a quantum physicist. “Because these bubbles are so small and last for such a short time, they can never be observed directly,” says Perlman. “But they would affect light in an interesting way.”

### Who discovered quantum foam?

John Wheeler

Quantum foam (also referred to as space-time foam) is a concept in quantum mechanics devised by John Wheeler in 1955. The foam is supposed to be conceptualized as the foundation of the fabric of the universe.

**Is quantum foam random?**

“This random, probabilistic froth is the thing of which the singularity is made, and the froth is governed by the laws of quantum gravity. In the froth, space does not have any definite shape (that is, any definite curvature, or even any definite topology).

**Is quantum foam dark matter?**

The galactic `dark matter’ effect is regarded as one of the major problems in fundamental physics. Here it is explained as a self-interaction dynamical effect of space itself, and so is not caused by an unknown form of matter….’Dark Matter’ as a Quantum Foam In-Flow Effect.

## Is quantum foam energy?

In this artist’s impression, spacetime at the Planck scale is a quantum foam. A new analysis suggests that even though this foam may have an enormous energy, it can still resemble a zero-energy vacuum on large scales.

### Why does quantum foam exist?

Quantum foam (also known as spacetime foam or spacetime bubble) is the quantum fluctuation of spacetime on very small scales due to quantum mechanics. Matter and antimatter is constantly created and destroyed. These subatomic objects are called virtual particles. The idea was devised by John Wheeler in 1955.

**How does string theory relate to quantum field theory?**

Interaction in the quantum world: worldlines of point-like particles or a worldsheet swept up by closed strings in string theory. The application of quantum mechanics to physical objects such as the electromagnetic field, which are extended in space and time, is known as quantum field theory.

**Is there such a thing as quantum foam?**

Quantum foam or spacetime foam is the fluctuation of spacetime on very small scales due to quantum mechanics.

## When did John Wheeler invent quantum foam?

Quantum foam or spacetime foam is the fluctuation of spacetime on very small scales due to quantum mechanics. The idea was devised by John Wheeler in 1955. With an incomplete theory of quantum gravity, it is impossible to be certain what spacetime would look like at small scales.

### Which is the string field theory of gravity?

The string field theory of the closed strings of the B-model is known as the Kodaira–Spencer theory of gravity and was developed by Michael Bershadsky, Sergio Cecotti, Hirosi Ooguri and Cumrun Vafa in Kodaira–Spencer Theory of Gravity and Exact Results for Quantum String Amplitudes .
