The future of space travel could have ships that use supernovae as fuel and fly at the speed of light


Avi Loeb, head of the Galileo Project, founding director of Harvard University’s Black Hole Initiative, explained in a report that the future of space travel could have ships using supernovae for fuel.

The also director of the Institute for Theory and Computation of the Harvard-Smithsonian Center for Astrophysics and author of the bestseller “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth” also suggested that these spacecraft could fly at the speed of light.

The text published in El Confidencial details that the powerful flash of light from the explosion of a supernova could serve as fuel for a ship to travel at that speed.

The theory explained

The study shows, for example, that a solar sail weighing less than half a gram per square meter can reach the speed of light even though it is separated from a stellar explosion by a hundred times the distance of the Earth from the Sun.

This is due to the typical luminosity of a supernova, equivalent to a billion suns shining for 30 days.

Another way to power the ships of the future would be to use powerful lasers to push light sails better than the Sun itself. The Breakthrough Starshot Project aims to reach several tenths of the speed of light by pushing a light candle for a few minutes with a laser beam 10 million times brighter than sunlight on Earth.

For these possibilities, it is necessary to have civilizations in our galaxya longing for astronomers who dream of colonizing space.

If we are lucky enough to have many technological civilizations in our galaxy, there could be swarms of solar sails around massive stars, patiently waiting for their explosions.”, adds the expert.

Also, navigate at the speed of light using the natural flashes of a supernova would save the costly expense of building artificial launch systems.

The most economical possibility is that a civilization, living near a massive star, “parks” numerous solar sails around it, waiting for a powerful explosion that launches the sails at the speed of light.
