Instead of high-tech spacecrafts, are intelligent aliens using stars to travel around the galaxy? That’s what a new research paper suggests.
According to Dr. Clement Vidal, a philosopher from Vrije University Brussels in Belgium, believes two stars binary systems, spidar pulsars and redback pulsars, are the most likely to be used by aliens to travel the galaxy. Pulsars are created when a supernova explodes.
“Since about half the stars in our galaxy are in binary systems where life might develop too, we introduce a model of a binary stellar engine,” Vidal wrote in his research paper. “We apply the model to candidate systems, spider pulsars, which are binary stars composed of one millisecond pulsar and a very low-mass companion star that is heavily irradiated by the pulsar wind.”
Universe Today breaks down in layman terms how aliens could possibly use a spidar pulsar to travel through space.
“A spider pulsar is a pulsar with a companion, usually a red dwarf, a brown dwarf, or even a planetary-mass object. They’re called spider pulsars because it’s as if the pulsar spins a web of powerful beams of radiation that strips away the companion’s mass, eventually destroying it.
Vidal’s paper describes the payload as a pulsar with about 1.8 solar masses and the propellant as its low-mass companion star with between 0.01 and 0.7 solar masses.
