From this link:
The Sun is 4.6 billion years old and is estimated to live in this stable phase another 4.6 billion years.
Since the Sun is a star, once it reaches the end of its lifetime, it will become a supernova, at least from what I've learned. From this link:
They can only happen when an aging massive star can no longer generate energy from nuclear fusion and undergoes a rapid gravitational collapse. This collapse releases potential energy that heats up and throws off the outer layers of the star in the form of an enormous explosion.
Since the Sun clearly fits the criteria for a supernova to occur (aging, massive), does this mean we could recharge the sun's batteries by refueling it with items that create energy from nuclear fusion?
I'm pretty well aware this is probably a crazy idea, but what I'd really like to know is, how feasible could it be?
