Dan Hooper, a senior scientist with Fermi National Accelerator Laboratory has written a paper outlining a way future aliens could keep their civilizations alive in spite of the isolation due to an expanding universe. In his paper uploaded to the arXiv preprint server, he suggests they might consider collecting and storing stars.
Advanced alien civilisations could build a machine capable of moving a star – and we might be able to catch them in action.
The idea, thought up by Alexander Svoronos at Yale University, is called a Star Tug and would allow civilisations to avoid cosmic disasters.
“It’s a megastructure that can be used to move an entire star system,” says Svoronos. “If their star system is going to be in proximity of a supernova, they might want to try to avoid it."
Stars Aren’t Supposed to Go Out Like This
When a massive star went missing, astronomers expected to find a supernova in its place. But there wasn’t one.
