Intelligent consciousnesses outside of Matrioshka brains may communicate via wormhole networks.

Examples of this use include the Matrioshka brain and the Matroska media-container format.

The Matrioshka brain concept is based on this stellar engine concept, extracting energy for a specific purpose: data processing.

Humans colonize Saturn's upper atmosphere as the inner planets are dismantled into a Matrioshka Brain.

This proves to be a normal stage in the life-cycle of an inhabited solar system; the galaxies are revealed to be filled with such Matrioshka brains.

A matrioshka brain is a hypothetical megastructure proposed by Robert Bradbury, based on the Dyson sphere, of immense computational capacity.

In Godplayers (2005), Damien Broderick surmises that a matrioshka brain would allow simulating entire alternate universes.

A Matrioshka brain is a collection of multiple Concentric Dyson Spheres which make use of different wavelengths of light.

There are three classes of stellar engines, explained in more depth here and another variant, called a Matrioshka Brain, which harnesses a star's energy entirely for computer processing needs.

Bostrom speculates that if humans deliberately evolved to a post-human stage the species would run massive computer simulations before each stage using machines such as the Matrioshka brain.

For example, an alien civilization may form a Matrioshka brain or a black hole and communicate using neutrinos or gamma-ray bursts at bandwidths that exceed our receiving capabilities.

For example, Matrioshka brains extract energy for purposes of computation; Shkadov thrusters extract energy for purposes of propulsion.

Another economic argument is that although advanced virtual civilizations - possibly en route developmentally to a Matrioshka Brain - could engage in travel to other star systems, they choose not to.

A matrioshka brain design is concentrated on sheer capacity and the maximum amount of energy extracted from its source star, while a Jupiter brain is more optimized for computational speed.

One idea suggested by Charles Stross, in his novel Accelerando, would be to use it to run perfect simulations or uploads of human minds into virtual reality spaces supported by the Matrioshka brain.

Additionally, a variant of the Dyson sphere has been proposed which would be difficult to observe from any great distance; a Matrioshka brain is a series of concentric spheres, each radiating less energy per area than its inner neighbour.

The futurist and transhumanist author Anders Sandberg wrote an essay speculating on implications of computing on the massive scale of machines such as the Matrioshka brain, published by the Institute for Ethics and Emerging Technologies.

As events progress in Accelerando, the planets of the solar system are dismantled over time to form a Matrioshka brain, a vast solar-powered computational device inhabited by minds inconceivably more advanced and complex than naturally evolved intelligences such as human beings.

In the novel Accelerando by Charles Stross, a Dyson swarm (possibly a Dyson bubble) of computronium forms a massive matrioshka brain around the sun providing virtual space for trillions of uploaded human minds and corporate AI.

The term "matrioshka brain" was invented by Robert Bradbury as an alternative to the "Jupiter brain"-a concept similar to the matrioshka brain, but on a smaller planetary scale and optimized for minimum signal propagation delay.

The nanoscale computers of each shell would be designed to run at different temperatures; shells or components at the core could be nearly as hot as the central star, while the outer layer of the matrioshka brain could be almost as cool as interstellar space.

The idea of the matrioshka brain violates none of the currently known laws of physics, although the engineering details of building such a structure would be staggering, as such a project would require the "disassembly" of significant portions (if not all) of the planetary system of the star for construction materials.
