There is a real need to reach these extreme speeds because the galaxy is so huge.
The solar system is 100,000 light years in radius, so it is necessary if you want to to travel between the stars.
Even the nearest star is four light years distance, so even with the fastest rocket, it would take 20,000 – 30,000 years to reach.
Professor Kipping explains: “We would like interstellar travel to take centuries-long time scales at least, maybe even decades time scales.
“And if you want to do that, you will have to get close to the speed of light – and the Halo Theory provides a means of achieving that.
