Our neighboring galaxy, Andromeda, can easily be seen with the naked eye during moonless nights. Isn’t it frustrating that we can see the galaxy, but we can’t travel to it using the world’s current technological progress? But is that really true?
The fact is that there is a way to travel to another galaxy, although the distances are almost beyond human comprehension. For instance, the distance that separates our Milky Way galaxy from Andromeda is about 2.53 million light-years. In other words, we would need 10 billion years to reach Andromeda using our current technology. We hate to bring bad news, but no human being will live that long.
There has to be a faster way to reach at least the closest galaxy to our own.
A wormhole is what we need
A wormhole placed somewhere in our own Solar System would represent the cosmic door to another galaxy. By accessing it, we wouldn’t have to deal with the enormous distances that separate galaxies anymore. That’s because, by definition, wormholes are nothing but shortcuts in spacetime.
If it sounds too good to be true, well, guess what? It is! While the math calculations tell us that wormholes should exist somewhere out there in the Universe, we would need a tremendous amount of energy, more than our planet would ever be able to produce, to create at least one single wormhole.
Wormholes don’t occur naturally, as someone or something needs to create them. Finding a wormhole near planet Saturn, for instance, as if it was placed there by a superintelligent alien civilization, such as suggested in the sci-fi ‘Interstellar’ movie from 2014, would be an ideal scenario. The only problem is that there aren’t any wormholes near any of our Solar System’s planets, as far as astronomers know.
Furthermore, waiting for a superintelligent alien civilization to build a wormhole for us to reach other galaxies or solar systems is as realistic as waiting for those same extraterrestrial beings to give us a “lift” themselves in their spaceships to another galaxy or solar system. We’re not even sure that highly-intelligent aliens exist in the first place! There is an extremely small chance for such a scenario to happen, of course, but it’s highly improbable. We could even say that there are higher chances for the world to find a way to generate unlimited energy to create a wormhole near our planet.
What exactly is a wormhole?
To understand the concept of wormholes better, you need to imagine our physical spacetime as a sheet of paper. Instead of going from point A to point B in a straight line, why not fold the paper itself (the spacetime, in our case) so that we can rapidly connect those two points with an imaginary line that will be much shorter? That’s basically the whole idea of a wormhole: a shortcut through spacetime.
Why should we go to another galaxy?
Finding extraterrestrial life is one of the main goals of astronomers. While our own Solar System is pretty much sterile except for the wonderful abundance of life that exists on Earth (roughly 8.7 million species), we need to look for alien life in other solar systems and maybe even other galaxies. The closest solar system to ours is Alpha Centauri, which is located about 4.3 light-years away from Earth. Nobody knows exactly if there is any life dwelling there, but what we know for sure is that there are exoplanets.
Going to another galaxy would be a huge step for mankind, and it would mean drastically improving our chances of finding alien life.
You got the main idea: wormholes are probably our only chance of escaping at least our solar system, but nobody can build one using humanity’s current knowledge. The existence of wormholes is possible in theory, but we can’t be sure when it comes to putting it into practice. If you somehow know the secret to creating a wormhole, please don’t be selfish and share the information with us in the comment section! Who knows what wonders await us in another galaxy?
