Type III Dyson Sphere of Highly Advanced Civilizations around a Super Massive Black Hole

TL;DR

This paper proposes a novel concept of a Type III Dyson Sphere around a supermassive black hole, enabling advanced civilizations to efficiently harness and transmit energy, expanding SETI search strategies.

Contribution

It introduces a new model of energy collection and transmission around SMBHs for advanced civilizations, suggesting detectable signals for SETI.

Findings

Energy transmission via coherent electromagnetic beams is feasible.

A galactic club of Type III civilizations could coordinate energy use.

Detection of such signals could expand extraterrestrial intelligence searches.

Abstract

We describe a new system for a society of highly advanced civilizations around a super massive black hole (SMBH), as an advanced Type III "Dyson Sphere", pointing out an efficient usage of energy for the advanced civilizations. SMBH also works as a sink for waste materials. Here we assume that Type III civilisations of Kardashev classification [1] form a galactic club [2] in a galaxy, and the energy from the SMBH will be delivered to the club members, forming an energy control system similar to power grids in our present society. The energy is probably transmitted by a sharp beam with coherent electro-magnetic waves, which provide a new concept for the search for extraterrestrial intelligence (SETI) via detection of such energy transmission signals. This expands the search window for other intelligences within the Universe.
