As most of you know, the Sun will eventually die and destroy all of us. Stars like the Sun shine by burning lighter elements such as hydrogen in a process known as nuclear fusion. And when the hydrogen supply in the Sun runs out, it will become a red giant and engulf many of the solar system planets, including Earth. There is no question that we will all die.

If the Sun will die from running out of hydrogen, a logical solution would be to provide it with additional hydrogen. There are many sources of hydrogen easily accessible on our planet, but one of the most efficient ones is water. We obviously can’t spray the Sun with a hose, as water puts out fire. Instead, we will supply water in a much more indirect, but still relatively efficient, way. Allow me to introduce - the watermelon.

Watermelons have some of the highest water concentrations of any plant. They are also extremely round, making them an effective projectile to launch hundreds of millions of kilometers away. However, using watermelons does present a problem: how are we going to supply the mass of the Sun with a few fruits? The answer is simple: special relativity.

Instead of launching an impossibly large amount of melons, we can instead drastically increase the mass of a single watermelon. According to Albert Einstein’s theory of special relativity, a moving object will gain more mass the faster it travels, approaching infinity the closer you get to the speed of light. This also means that there is a certain velocity where the mass of the watermelon is just enough to support the Sun for enough time, yet not overwhelm it with mass and create a black hole. Through a bit of calculation, by accelerating a single watermelon to 99.99999999999999999861% the speed of light, it will be able to sustain the Sun for a year. Routinely doing this solves the problem.
