I've dedicated my life to one goal: the creation or discovery of a wormhole. I wish I had set myself upon this goal sooner, instead of wasting my twenties wandering aimlessly through life. It'll be a decade before I get my PhD in physics, and I sincerely hope that donors will be receptive to a 40-year-old postdoc with dreams of creating a wormhole. I'm aware of the 99 percent probability that I will fail in my mission, and that I'll die not even coming close to finding or creating a wormhole. But if even just my research and experiments can help future generations master transgalactic or even transuniversal travel, I'll be pretty damned happy.
Faster-than-light travel is one of the three most important technological achievements our species will ever have. It will free us from the shackles of the Solar System, and open up an entire universe of possibilities. Even the first FTL tech will allow us to reach millions of worlds. Then we will be able to reach billions. Then trillions.
We have a long way to go. But there's technology that even now is being worked on, such as the Alcubierre drive. How far in the future the drive is depends greatly on materials and energy requirements, but eventually we'll get there. However, even the Alcubierre drive will get us to Alpha Centauri in weeks or months, as opposed to much more convenient days. That's why wormholes are so crucial.
Wormholes have yet to be observed in nature, though it's thought that quantum foam (if it exists) is made up of countless tiny wormholes sparking in and out of existence. If those wormholes really are there, it's just a matter of creating a device sensitive enough to detect them, and then creating new equipment that can "trap" and then expand one of those microscopic wormholes to a macroscopic scale. The energy required to do this is probably gargantuan, and probing to that scale may take a particle accelerator the size of Earth's orbit around the Sun, powered by the full solar force of the Sun itself (and/or antimatter reactors).
There is another option. Maybe sheer power isn't the only way. Perhaps it's just a matter of creating something "sharp" enough to poke a hole in space-time. If space is like a balloon, and all the stars and galaxies are like fingers pushing into that balloon, then what we need is a tack. Something that won't push against space-time, but go right through it like a needle. Unfortunately, I have no idea what that material might be.
In any case, eventually wormholes will be found or created. It may take millennia, but it will happen. And when it does, stars that are years, centuries, and millennia away may only be a few days away. Or a few hours. Maybe even just a few minutes. Our descendants will be able to spread throughout the stars, colonizing trillions of worlds.
It may not be just interstellar travel that will be impacted. The wormholes could be realms of entirely new forms of energy, energy that can power even more powerful machines that will allow our descendants to finally shatter the greatest barrier the universe can throw at us: time.
But before that day arrives, our descendants will have to face the demons of our past...and threats yet to come.
