At some point in the far future, our descendants may want to relocate the Sun — a hypothetical megascale project referred to as stellar engineering. But as crazy as that sounds, the physics says it could work. Here's how we'll do it.
A Type I Kardashev civilization would use the power of its entire planet. Type II, a star system, and a Type III would harness the energy of an entire galaxy. It boggles the mind to think about the engineering required to rearrange the stars of an entire galaxy.
