As civilizations advance, they may need to migrate across the galaxy, and some researchers speculate they could use their own stars as massive engines.

New research explores the possibility of a binary stellar engine, particularly spider pulsars, as potential propulsion systems. By carefully manipulating these systems, a highly advanced extraterrestrial species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.
